Preface

A Few Words

Why this came to be

There's nothing much to say why I am writing this report in one single page except that I want the information and discoveries I wish to share written in an organized manner rather than on different blog posts. This report also serves as my journal or documentation of the many information I have discovered while studying statistically this type of lottery. If you are interested how this blog was conceived, you can read Why I Created This Blog on one of the pages here with the same title.

Studies I made used simple methods, basic arithmetic mainly counting, adding, and calculating percentages. What made it complicated is that I had to deal with a large volume of data, faced with a challenge on how to calculate numbers in one click. Equipped with a programming skill, the first digital tool I used was MS Access - a database program. Unfortunately, time outdated my computer and software had become unaffordable. Eventually, I switched to Excel. Macbook replaced my notebook which made me switch to Numbers (a Mac spreadsheet app). For the reason that I wanted to share my data live on this blog, I switched to Google Sheets. Unlike any database program, the use of a spreadsheet program was more of a challenge: large volume lags the sheets; you can not automate everything; studying how the built-in functions work and how to formulate them can be brain excruciating. Nevertheless, in the end, it was all fun and self-rewarding.

To make this report comprehensive even to the ordinary mind, I tried not to use technical terms but not to avoid to mention them totally, just so to express that I know what I am really talking about Statistically speaking. I also made up some terms specifically for this report. Do not worry; everything will be explained.

Do I have the right to write this stuff? Maybe, I don't. I am simply an Accountant by profession with some programming skills and with a nerdy passion for numbers. In the entire report, after this preface, I will be using most of the time, ignoring the strict and formal rules of creative writing, We or You instead of I simply for the sake of a conversational feel.

Warning: This is a long read! The rich information may overwhelm you; so, pace your reading and be patient.

6/58 Lottery and Its Study: An Overview

Just about what this is

This part may not interest you, so just skip anytime. I won't mind. You may jump to the Table of Contents and pick the topics that interest you most. However, if you wish to learn a little about Math, elegant mathematics, this type of lottery, and how I measured everything, you are mostly welcome. Just to prove that I make sense out of it. Let's begin your journey.

[ This report is a work in progress. Though I started writing this in 2018, the data are updated if necessary to see if there are significant changes to the statistics. You will find a date stamp in Part 2 Chapter 1 that tells you up to what date the data has been updated. ]

ABOUT

The passion beneath those numbers

The first ever lottery in the Philippines was launched on March 8, 1995. It was something new, and it was legal, so I was a regular player just playing one ticket each time. Back then, lottery draws were not done live on TV. Nothing on the web even. The only access to the results were either you drop by at a nearest lotto kiosk or buy a newspaper. One lotto outlet, called Winsum, would sell a booklet showing all lotto results of the past. And each time, I would buy one until I have so many that one day I decided to throw them away. However, being a computer programmer, I saw the list of numbers a potential database. That's when I started building a database of lottery winning numbers and explored anything I could think of behind those numbers. It became a passion.

When blogging on the Net started as a new web hobby, I decided to document my discoveries; thus, the birth of this blog: LottoTips888.

Each time I would analyse the numbers, I kept asking the universe: what is the secret behind those numbers? I wanted to know. Sometimes, I would get inspirations to make some calculations. Some results excited me; some, frustrated me. But, I never stopped exploring. This report is the product of those countless nights tapping my keyboard and figuring out how I can manipulate those numbers to come out with something relevant.

Starting from the winning frequency of each number, what statistics reveal is not enough. Then I analysed patterns: low vs high numbers; odd vs even numbers; and so forth and so on. But they were not enough. Something was missing. So, I started digging even deeper. How deep have I gone? You will all find out as you read along. Anything I discover is written on this blog.

CONTEXT

The figures behind the numbers

This report is about a statistical study of the collected drawing results of a 6/58 lottery system. It aims to find out if there is anything significant behind those numbers once we tweak them, re-arrange them, group them, and do anything under the sun. Initially, the studies covered results from 2015 - 2018. Later studies included data until 2022.

The report classifies two types of probability: general (all-time) and current (recent periods). General probabilities, set as standards, are based on all actual results beginning from 2015 until 2022 (and in some cases, up to the present). Current or trending probabilities, with the aim to capture what's currently trending, are based on the most recent draws which may cover 6 draws, 21 draws, 33 or 60 draws.

How I explore the numbers start with a question. For example, the very first question that came to my mind was: How often does each lotto number win? Can the figures erase any doubts? But then, soon I found out that mere counting is not enough. I had to go further deeper.

Here are a few of the questions that came to mind when I started studying the winning numbers.

What are the odds of winning a 6/58 lottery system? Are chances either to win or to lose? Are top winning numbers guarantee a sure win?
Would probability data reveal better chances of winning, or otherwise? With various probability measures used to calculate rates of probability, how can they aid in increasing the chances of winning?
How often forms and patterns are repeated? If such significantly exist, do they guarantee better chances of winning?
What are trend probabilities? How do they differ from all-time probability measures? Which one work well?
And I think, the most wonderful set of questions to ask is: Who designed randomness? Why is it so perfect? Is there someone in the universe who control it? I think, these are questions that we could never get answers from.

There are numerous metrics that can be adapted and aid in analysing groups of winning numbers. These metrics are discussed in full details in later chapters.

As said earlier, this is a progressive report, therefore, data may include lottery results from the most recent ones, not only from the old past, to create and collect measured data, analyse statistical figures, observe patterns and behaviour, and come up with findings.

What Covers The Study

This study is classified into four parts:

Part I is an overview about what this report is all about: its content, what covers the study, and in general, what the 6/58 lottery system is.
Part II analyzes historical data with the aim to discover statistical numbers that could somehow make sense.
Part III examines current data based on shorter periods to find out if their metric data would have any difference from all-time statistics that were established in Part II. It answers the question: Are trending data would be more relevant than all-time data?
Part IV discusses how to use the Lotto calculator that I created for the 6/58 lottery system.

The following TOC provides a shortcut to the specific topics.

How to play and win from PCSO's Ultra Lotto 6/58.

What Is A 6/58 Lottery System?

Basic Information

A 6/58 lottery system is a lottery system wherein six numbers are drawn from numbers 1 to 58. The first six numbers drawn make the official winning numbers. The method of drawing the six numbers vary. It can be digital or traditional. The usual traditional method of drawing the numbers use a tumbler. This tumbler contains 58 pingpong balls numbered 1 to 58. Each pingpong ball is of the same size, shape, and weight with precision of up to ten decimal points or longer.

Today, lottery companies use air-pressurized tumbler to ensure that no hands intervene with the drawing of the lottery results.

In the Philippines, this type of lottery is called Ultra Lotto 6/58. Lottery companies from other countries may call it some other names. Whatever it is called, the names are irrelevant.

Ultra Lotto 6/58 is being managed by Philippine Charity Sweepstakes Office (PCSO), a Philippine government agency. Drawing of results use an air-pressurized tumbler. Only one tumbler is used. This tumbler contains 58 pingpong balls numbered 1 to 58. The first six balls drawn determine the six winning numbers. Winning numbers are in no particular order.

Featured Lottery Game: PCSO's Ultra Lotto 6/58

Ultra Lotto 6/58 started playing in 2015. Its very first draw was held on 8th February 2015. The winning numbers were 57 • 05 • 53 • 42 • 18 • 55 with a ₱50 million jackpot. Since then, more than 1,500 draws were held.

How To Play PCSO's Ultra Lotto 6/58 and How To Win It

To play Ultra Lotto system 6/58, you pick six unique numbers from 1 to 58. Your six numbers can be in any combination and order. Using a bet card, you mark the card corresponding to your six numbers. A lotto operator feeds the card to a computer to generate a ticket. Printed on this lotto ticket are the six numbers you are playing. You can play as many tickets as you like. Each set of six numbers played costs ₱20 prior to 2026; ₱25 currently.

Under the Aquino regime, PCSO taxed the price of each lottery ticket increasing it to ₱24. The Duterte administration moved it back to ₱20. The Marcos administration increased it to ₱25 in 2026 to include tax. Jackpot prices were also raised.

How You Win The Game

If the six numbers you played are the same numbers drawn during the official drawing of the lottery, you win the jackpot prize. If there are more than one winner, the winners share the jackpot prize equally. You can win a smaller prize if you matched only 3, 4, or 5 numbers. The order the balls are drawn is irrelevant.

What are the options in marking the bet card?

LP or Lucky Pick. The system generates the numbers for you.
Void. Should you make a mistake marking the card, mark void.
5R or 5 Roll. Allows you to mark 5 numbers and let the system combine them with the rest of the numbers.
System Play. With system play, you can mark 7 up to 12 numbers. Based on your selected numbers,the system will generate all possible combinations that can be made out from the numbers you have chosen. You can combine LP with system plays. The back of the card lists all the number of combinations that can be formed for each system play and how much you will have to pay. If you are using an old card, most likely the price is based on the old price of ₱20.
Advance Draws. You can play your numbers for future draws up to the next 6 draws.

For your reference, as of 2026, the following are the number of combinations you play for each system play together with its total cost.

Table of system plays, number of combnations and cost

When are Ultra Lotto 6/58 draws held?

Ultra Lotto 6/58 draws are held every Tuesday, Friday and Sunday.

How much one play costs?

Each play costs ₱25. Initially at ₱10, then ₱20 per one-combination ticket.

How much is the initial jackpot prize?

Jackpot prize from Ultra Lotto 6/58 starts at ₱75,000,000.00 (net of agent's prize commission).

About The Study

Scope and Extent of the Study

In order to accomplish our objective for this study, we need actual data produced by an existing 6/58 lottery system. To achieve that, we need to collect a good volume of actual draw results from the said lottery. It really does not matter from which date we begin collecting. What matters is to establish an appropriate amount or number of data. Statistically speaking, there is no single universal rule as to the size of our sampled data that is enough for every project nor is there a hard maximum cap on sample size. What is enough depends entirely on the research goals, population size, and the variability of the data. What is important is that for our sample data to yield a low margin of error (typically around ±2.5% to ±3.0%) at 95% confidence level. To achieve a 95% confidence level with ±5% margin of error, a minimum of 385 samples is good enough. For lottery data, we need to find out how much sample size do we need considering a finite universe of 40,475,358 possible combinations.

Featured Subject of the Study: PCSO's Ultra Lotto 6/58

For the study of this 6/58 lottery system, results from PCSO's Ultra Lotto 6/58 of the Philippines were used. The results cover the period 8 February 2015 (its very first drawing) up to, as much as possible, the current date.

What if I live outside the Philippines, can I use this study?

For other players in other countries, so long as your lottery system method of drawing use the tumbler method, the information here may still serve useful for adapting it to a similar system in your area. Otherwise, if you want to use your own draw results, you can just download the tools provided here and replace the results with that of your local lottery’s.

Actual Data Covered and Sampled

Following is a set of information about how much is covered by this study. The information shows the size of the data (count of draw results), the range of draw dates covered, the number of possible combinations, jackpot odds, and the frequency odds baseline. This information is fired from a database stored on Google Drive. Jackpot odds is the probability rate of a winning combination to win each draw; or your chance of winning assuming you are holding a single ticket. Baseline probability is the expected average draw hit rate or probability of each number to be drawn out.

Ultra Lotto 6/58 Results Database

If your are interested to view the content of the database, this particular page on this blog lists all the results of Ultra Lotto 6/58 up to a certain date as indicated here. The database are presented by draw date; and the other in numeric sequential order. You can use the numeric sequential order to form your combination that is yet unique; i.e., not a duplicate of previous winners. Statistics say that, so far, all winning combinations are unique.

Methodology: Simple Basic Math

Generally, most method used in the studies is simple math such as summation and calculating the percentage. It gets complex, however, when presenting the data on a spreadsheet such as manipulating the database with the use of complex spreadsheet functions and formula. Methodology in statistics is actually a complicated concept; so, I will just skip the technicality. Whatever method I used, it will be discussed in related chapters. An example below is one of them.

Grouping the lotto numbers with related attributes

Quantiles divide probability data into equal groups, such as a group of four, five, six or ten. If grouped into four, each group is called a quartile. If five, quintiles. If six, hextiles. There are studies that classified the numbers by frequency rank, sequence group and time/age.

Lotto system 6/58 draws 6 winning numbers. If we are going to group the lotto numbers into 6 groups, is it possible that each winning number would come from each group; or would there be a group that would not produce a winning number?

Dividing the numbers or data into different groups reveal more information as to which numbers win most often. In the very first chapter of Part II, the data were divided into six, called hextiles, according to the frequency of winning of each lotto number. In Chapter 9 of Part II, The Probability of Number Diversity, the lotto numbers were grouped by their first digits such as 00s, 10s, 20s, 30s, etc.

Setting The Standards

In setting the standards, we measure probability metrics based on all actual data; meaning, all draw results starting from the beginning. Here, we establish which metrics are mostly common or usual.

What comprises a winning combination
Probable range of winning numbers. Not all combinations are probable.
Distances or the difference between two consecutive numbers. Predicting the next probable numbers.
The probability of time. Identified sets of periods considered significant in establishing the probable potentials of lotto numbers. The probability of an event to take place again such as when a number is likely to win again.
The probability of winning ranks. Do top winning numbers win all the time? Maybe not.
The probability of number diversity.
Trending values based on periodic winning frequency; standardising the parameters that delimit probabilities. How to recognise trending numbers.
Common forms and patterns of lottery results
- Top vs bottom vs middle numbers
- Low vs high numbers
- Odd vs even numbers

Core Mathematics

Permutations vs Combinations

In Statistics, there is a difference between permutations and combinations. In permutations, the order of the numbers is significant. In combinations, the order of the numbers is irrelevant. In permutation, ABC is not the same as CBA. In a combination, ABC is just the same as ACB, BCA, BAC, CAB, CBA. For the reason that Ultra Lotto system 6/58 disregards the order of numbers, we are only after all possible combinations.

Number of All Possible Combinations

To determine the number of all possible 6-number combinations that you can make from numbers 1 to 58, use the Combination formula.

The other way to write it is —

C(n,k) = n! ÷ [(n - k)! k!]

which you read it as —

n choose k equals the factorial of n divided by all over the factorial of n minus k times the factorial of k. In other words, find all possible combinations of k objects from n items.

Let's substitute the formula with lotto 6/58.

C(58,6) = 58! ÷ [ (58 - 6)! × 6! ]

Let's read —

58 choose 6 = the factorial of 58 divided by all over the factorial of 58-6 times the factorial of 6.

The result is — 40,475,358 possible combinations all in all.

In Excel and Google Sheets, the function to find the number of combinations is COMBIN(n,k); eg COMBIN(58,6).

Jackpot Odds Of Winning

With over 40 million combinations, your chance, therefore, or probability of winning a jackpot from a 6/58 lottery system is 1:40,475,358 or 0.00000247%. By playing two combinations, you double your chance. To increase your odds of winning to 1%, you need to play 404,754 combinations; this will cost you ₱8,095,080.

Probability Measures

Probability is a math word that measures how likely it is for something to happen. It uses numbers from 0 to 1, where 0 means impossible and 1 means absolutely certain. For example, flipping a coin gives you a 50% or half a chance of landing on heads. In lottery, the chance of each ball to be drawn out of 58 balls is 1 / 58, i.e., 1.72%. There are two types of probability: theoretical and empirical.

Theoretical Probability (Fixed and Constant)

The theoretical probability is based on the physical attributes of the game, not on actual historical data. In the case of 6/58 lottery system, there are 58 balls numbered 1 to 58; 6 balls are drawn to determine the winning numbers for the day. Dividing 6 by 58 results to 10.34%; this is the probability, somewhat like constant, of six balls being drawn. This probability does not change ever as long as there are 58 balls in the tumbler and 6 balls are drawn each time. The significance of this probability rate is to determine how much a specific number drifts from this rate based on historical performances.

Empirical Probability (Historical)

Empirical probability is based on historical or past data—data based on events that already happened. In contrast with theoretical probability, empirical probability can change depending on the subject data. For example, the lotto #22 has won 177 times based on actual 1,516 data results (1,516 actual 6/58 lottery draws). Based on those data, #22 has 11.68% empirical probability. As explained earlier, you can use the theoretical probability figure as a guide to find out how #22 has been performing so far, which is 1.34% above par.

To illustrate:

Based on 1516 results, #22 has won 177 times. The calculated empirical (based on historical data) probability is 11.68% (177 divided by 1,516 total draws sampled). Comparing 11.68% with the theoretical probability of 10.34%, it means that lotto #22 is over-performing its theoretical average rate by 12.96% (11.68% / 10.34%) – 1. So, would you bet on #22? Why not?
To compare with lotto #30, this number has won 157 times, an empirical probability of 10.36%, which is close to its theoretical probability of 10.34%. This number is performing just fine.
In contrast, lotto #33 has won only 139 times, an empirical probability of 9.17%, which is slightly below its theoretical performance of 10.34%. So, would you bet on #33? Maybe. It's a matter of time, which is your are going to learn later.

Margin of Error

Margin of Error (MOE) expresses how close statistics to truth. It is usually expressed with plus or minus.

When we look at lottery results, we can't be 100% certain that our calculations perfectly match reality. This is because we're only working with a limited number of past draws, not every possible draw that could ever happen. Think of it like tasting a spoonful of soup to check if it needs more salt; you don't need to drink the whole pot to get a good idea, but that spoonful might not be perfectly identical to the entire batch. This small difference between what we observe and what's actually true is called the margin of error. It gives us a range, instead of an exact number, within which the real probability likely falls.

For example, if number 23 appeared 45 times out of 500 draws, that's about 9%. But does this mean number 23 truly has a higher chance of winning, or is this just normal random variation? The margin of error helps us answer this by showing an acceptable range, such as 7% to 11%, within which the true probability might exist. If a number's frequency falls way outside this expected range, it becomes more meaningful and less likely to be pure chance, though in a fair lottery system, such patterns will still eventually occur due to sheer luck.

So, when studying lottery numbers, always remember: probability studies do not offer certainty. They offer educated estimates. The margin of error simply reminds us that our numbers have "wiggle room," and that even seemingly unusual patterns can still happen naturally in a truly random system.

To illustrate, let's calculate the margin of error of one of our probability findings.

The lotto numbers 01 - 58 were grouped into six such as: 1s, 10s, 20s, 30s, 40s, 50s. Based on 324 lotto results, 318 revealed that there's always 1 winning number that would come from each group.

Let's calculate its margin of error.

Margin of Error Formula

The formula to calculate the margin of error is ~

MOE = z √ {[p ( 1 - p )] / n }

where ~

n is sample size
p is sample proportion expressed in percentage
z is the confidence level (which is usually 95% expressed as 1.96; if 99%, 2.58)

You can read the formula as ~

The square root of p times 1 minus p divided by n multiplied by z equals MOE

Let's substitute the formula with our figures above.

Sample size n is 324, which is the number of draw results.
Proportion p is 318 or 98.15% probability (318 divided by 324).
Confidence level z is 99% expressed as 2.58 (this is constant based on a standard table).

So, how true is the 98.15% probability that there's always 1 winning number that would come from each group mentioned above? Let's calculate the margin of error.

MOE = 2.58 √ {[ 98.15% ( 1 - 98.15% )] / 324 } = ± 1.93% or 2% rounded off.

The MOE, therefore, is ± 1.93%. This means that the statement mentioned above is 96% to 100% true (98.15% plus or minus 1.93%)

Chi-square Test

Chi-square test is another statistical tool that checks whether something is truly random or if there's a pattern worth noticing. Imagine rolling a six-sided die 60 times. If it's fair, you'd expect each number (1-6) to appear about 10 times. But what if number 4 showed up 25 times, while others appeared less often? The chi-square test helps answer: "Is this just luck, or is something making the die favor number 4?"

For a lottery, the chi-square test works the same way. Instead of checking individual numbers one by one (like margin of error does), it looks at all 58 numbers together and compares how often each one actually appeared versus how often they should appear if the lottery were perfectly fair. If the overall pattern is close to what's expected, the lottery is likely random. But if the pattern is very different from expectations, it raises a flag that something unusual might be happening—though in most fair lotteries, results will naturally pass this test since randomness itself causes some numbers to appear more or less often by chance.

Simple way to remember it: Margin of error checks one number at a time; chi-square checks all numbers at once to see if the whole system still "feels" random.

For every probability measure I do, I will calculate either its MOE or chi-square test whichever is applicable.

Frequently Used Terms

Probability: In simple words, the mathematical measure of chance between 0 and 1 where 0 is impossible and 1 is possible. This is either presented in a percentage form (%),ratio (x:y), or decimal. Sometimes mentioned as probability rate or probability ratio. Other than chance, another synonymous word is odds. You would often encounter these words interchangeably.
Theoretical Probability (The Future): This is the math-based probability dictated by the physical rules of the game. Think of it as the standard expected outcome. For example, in the 6/58 lottery system, every single ball has an exact mathematical chance of being drawn among the 6 out of 58 balls, regardless of actual draw data. That expected probability is 6 / 58 = 10.34%; which means that you can expect every number to achieve this probability rate. But then, what if the probability rate based on actual data is less than 10.34% How do you look at it?
Empirical Probability (Historical): This is probability measure that is strictly based on historical data—from events that actually happened. You will mostly see empirical figures for the reason that we would be studying actual historical data.
Margin of Error (MOE): Margin of error measures how close to truth is our probability findings. The value is expressed with a plus or minus sign (±) to depict a range of values rather than one specific value. It tells us that whatever probability rate we come out with is not absolute; say, if the rate is 93%, it is more likely true to say 90% to 96%, which is plus or minus 3%.
Chi-square Test: Chi-square test checks all numbers at once to see if the whole system still feels random; or perhaps, there's something hanky-panky going on.
Law of Large Numbers: It is an observed behaviour that as the volume of sampled data grows larger, the probability metrics tend to be close or almost equal.
Frequency: The number of times an event or something has occurred or recurred. Mostly often used to refer to the winning frequency of a lotto number.
Winning Frequency: The number of times a lotto number has won in a given period, which could be all-time or from a shorter period. Usually labeled as Freq or Frq or simply %.
Occurrence: Similar to frequency, but usually used to refer to events other than the frequency of winning. For example, the occurrence of elapsed draws since the last time a lotto number has won.
Instance: Similar to occurrence but on a narrower perspective such as events constrained or contained within a given criteria or parameters, or homogeneous attribute from a snapshot of the database, such as a 30-day period. Commonly used to refer to instances that exist in a combination of numbers. For example, how many in the combination are from 20 – 29.
Instance of instance (ioI): In some cases, we would have to measure the existence or event of a number or its attribute within a common set of instances.
Elapsed Draws or Skips: Elapsed draws refer to the count of draws that have elapsed since the last win of a lotto number. In other words: how long has a lotto number not been winning? If the value of elapsed draw is zero, it means that a lotto number has won twice consecutively (a repeater). If the value is 1, it means that it last won prior. Elapsed draw is also called skip
TimeAge: TimeAge refers to the time a lotto number has not been winning prior to its latest win. Timeage can refer to the number of days or number of draws. In the case of lotto 6/58 in which draws are not held everyday, timeage refers to elapsed draws plus 1. In contrast with elapsed draws, if the value of timeage is 1 (instead of 0), it means that a lotto number has won twice consecutively; that is zero elapsed draw. Timeage is not a valid word. It was coined specially for this report.
Trend value: Also called trending value or trending score. This refers to the winning frequency of a number within a trending period.
Trend zone: Also referred to as the trending period. A trend zone refers to a certain period that comprises a smaller number of draws where numbers start to trend or cease to trend. In the case of a system 6/58 lottery, a trending period covers 21 consecutive draws starting from the most recent one. As study progresses, the trending period may change.
Hot zone: The hot zone refers to the most recent 6 consecutive draws. Also referred to as the winning zone or jackpot zone.
Delimiters: Delimiters are probability indicators that constraints your choices of numbers. With delimiters, numbers with the least probability of winning are removed. Thus, instead of choosing from 58 numbers, your choices become limited to a few.
Probability indicators: Any value that indicates any level or grade of probability. A similar term is probability factors or markers.
Rank: This is presented as an ordinal number such as 1st, 2nd, 3rd, etc.
Percentage Rank: Presented as %Rank, it is ranking presented in percentage form such as the top 10%.

As you read on, you will encounter terms used specially and differently for this report.

All-Time Statistics

SETTING THE STANDARDS

General probability based on all results

In this first set of chapters, all studies were based on all draw results, starting from the time Ultra Lotto 6/58's first draw, which was in the year 2015 and to cover until portions of 2022; and in some cases, up to the present as shown by the date stamp in Chapter 1. All in all, the mathematical studies covered over 1,000 drawing results (and growing) from Ultra Lotto 6/58. The purpose of this all-time statistics study is to establish a set of general probability standards which you may observe when picking and combining the lotto numbers that you wish to play.

Ch 1

Winning Combinations Are Unique

No Winning Combination Wins Twice, So Far

There are a total of unique 40,475,358 possible combinations that can be formed with a 6/58 lottery system. In a lottery draw, however, any combination can win twice or even more. There is no rule that they can only win once. The question is: Has there been any winning combination that has won twice or more?

A single number can win multiple times; likewise a pair of numbers; or even a trio. A quad of numbers can also win multiple times; that's also possible. What about 5 numbers? Yes, they can. Even a 6-number combination? Yes, but the question is: Has it happened, so far?

Let us see what data say.

We checked every winning combination to find out if any winning combination has won twice or more. Below is the result. Linked to the database at real time, if there are any winning combination that has won more than once, it will be listed below. If none, it will say "So far, each winning combination is unique."

Fig 2.1 List of winning combinations that have won more than once

Significance of Uniqueness

Let this finding be the first standard. On record, so far, all winning combinations from Ultra Lotto are unique, which means, none of them has won more than once. Every single set of winning numbers is not a duplicate of any winning combination. What is its significance?

First Standard

Each winning combination is unique; therefore, if you are going to play Ultra Lotto, make sure that your 6-number combination has never won before.

What if 5 of your numbers had won before, would you play them again?

Observed Findings

Lotto #s 14 and 22 are one of the topmost winners with a winning frequency of 185 and 184, respectively, in July 2026. Together, as a pair, they have won only 20 times.
Lotto #43 is the 3rd top winner, also with 184 wins. Together with #s 14 and 22, as a trio, they have won only once, that's on May 25, 2018.
Let's add another number. The 4th top winner is #06 with 183 wins. Together with #s 14, 22, and 43, as a quad set, it has never won yet.
If we add another number to form a 5-number combination, most likely, the result is also zero.
Therefore, if 5 or 6 of the numbers in your combination together have won before, might as well substitute 1 or 2 of your numbers with another. If 5, replace 1 or 2 with another. If 6, replace 2 or 3 with another.

How To Ensure Your Combination Is Unique

🔎 Somewhere on this blog is a list of winning combinations for Ultra Lotto. Search Ultra Lotto 6/58 results archive" (I published a dedicated page for Ultra Lotto 6/58 results history). The numbers are in numerical order, lowest to highest. That will be easy for you to check if your numbers have won before.

If you have no access to this database, follow this simple technique:

💡 Pick any winning combination from any date. Arranged the numbers lowest to highest. From any of the last 5 numbers, change at least 2 to any lower or higher number. For example, with 07-30-32-34-48-55 (28 July 2026 winner) as a winning combination, you may change 30 to 27 and 34 to 33 or 40.

Winning Performance of Each Number

How each number is doing

In this chapter, we explore:

The winning frequency of each of the 58 numbers of Ultra Lotto
We look at a different pespective of each winning frequency by measuring its performance based on the theoretical probability
What comprises the winning combinations: top or bottom numbers

Winning Frequency of Each Number

Perhaps, the first thing that crosses your mind and eager to find out is: which of the lottery numbers usually win? Let's find out.

In Oct 2022, the probability for each number to win ranges from 8% - 12%. Following is the result from more than 1,000 lottery draws. For the reason that from time to time, the data are updated, you may see a different set of statistical values. To give you real-time data, the information that follows show up to which date the sampled data cover.

Fig 2.1 Winning Frequency of Each Number

Perhaps, you have noticed from the chart above that the winning frequency of each number does not deviate much from the others. This happens when a study involves a large volume of data (Law of Large Numbers). To view the data metrics from a more significant perspective, we look, instead, at its performance rate. However, before we move further, let's establish first our probability baseline.

Baseline Probability = 10.34%

It is important to establish first our theoretical probability (also called expected rate or expected probability) metric so that we would have the baseline to compare our empirical (actual) probability values. By comparing the two (expected vs actual), we would know if the winning frequency of a number is performing as expected or beyond what is expected, or otherwise.

Our expected probability rate is 10.3448% calculated as 6 / 58. This is the probability rate that math predicts even before any draws happen. This theoretical probability rate of 10.34% serves as our baseline and it remains constant regardless of historical data. This means, by symmetry, every number has a 10.34% chance of being one of those 6 winners.

So right now, we are about to find out how the numbers are doing so far.

Performance Rates of Each Number

Fig 2.2 Performance Status of the 58 Numbers

The above data are arranged according to the numbers's winning performance rates. The top performers are on top as denoted by positive performance rates. Lotto numbers that have not been performing so far have corresponding negative performance rates. The chart, alongside also shows the numbers's empirical probability rate and frequency of winning. As a bonus, the last column indicates the "hot/cold" status of each number where a high number means cold or currently not performing well; a low number means that it is currently hot. It is divided into 6 groups (called hextiles). The first hextile, which you see on the first page, is the top 10 winning numbers of all time. The second top 10 winning numbers are presented on the second page; followed by the next 10 on the third page, and so forth and so on. The figures on the chart are updated from time to time as shown by the date you stumbled upon earlier. This date indicates up to which draw the data cover.

The Figures Explained

6 Groups. The lotto numbers are divided into 6. The reason for that is to classify the numbers according to their degree of performances. Thus, you can observe whether the winning numbers commonly come from the group of top performers or a mix of top and bottom. In addition to that, is it probable that each group would produce one winning number each?
Lotto № shows the lotto numbers 1 - 58 arranged according to each number's frequency of winning or performance, top performers on top.
Win Count is the winning frequency of each lotto number; i.e., the number of times each lotto number has won so far since the first draw of PCSO's Ultra Lotto 6/58. Just to give you an idea, lotto number 6 has won more than 130 times out of 1076 draws (the highest in March 2023); while the lotto number 37 has won 91 times (the lowest so far in March 2023). In July 2025, lotto number 6 remained on top with 163 wins at 11.93% probability. The number with the least wins went to #27 with 120 wins at 8.78% probability; while #37, the former lowest ranking number, rose to the 50th place with 130 wins at 9.52% probability.
Hit Rate is the (empirical / historical) Probability Rate in percentage. In March 2023, the highest probability rate was 12.17%; while the lowest was 8.46%. Notice that the probability rates slightly deviate from the 10.34% theoretical probability. Does it imply that each lotto number is doing well? The performance rates reveal the answer.
Performance. The performance rate is measured by dividing the empirical (actual hit rate) by the theoretical baseline of 10.34% minus 1. The result would either be a positive (performing well) or negative (not performing well) value. Positive if it is above 10.34%; negative if it is below 10.34%. It is easier to look at the performance rate rather than on the frequency values and hit rates because it gives you a better idea whether a number is winning well or not.
TimeAge. The age is a time value. It counts the number of elapsed draws plus 1. It indicates the last time a number has won. If 1, the number just won from the most recent draw; if 2, it won just prior. If higher, say 12, it means that the lotto number has not been winning for the last 12 draws (11 elapsed draws + 1). Another way to look at it is temperature. If the value is 0 – 6, the number is hot; if greater than 21, it is a cold number. You will learn more about this in the chapter Time Metrics.

You may have wondered if the top six numbers had won the jackpot before. At one point, the top six numbers were 06 • 14 • 25 • 22 • 13 • 34. Based on July 2026 data, these numbers have not made it to the jackpot yet; not even any 5 of the numbers combined. Four of these numbers had won only once. Any 3 of these numbers had won 34 times. If these are the top 6 winning numbers, how come they have not made it to the jackpot? So, we dig further.

Top Winning Numbers

What if you play all the top winning 29 numbers? What are your chances of winning?

Fig 2.2 is the result of that study.

Fig 2.3 Top 29 Lotto Numbers

Presented above are the top 29 winning numbers based on PCSO's Ultra Lotto 6/58 drawing results from 2015 to 2022. For each draw, the presence of the top 29 numbers were determined. These are the results.

Unique combinations from the top 29 made it to the jackpot 20 times (2%).
Any 5 of these numbers had won 130 times (12.7%)
Any 4 of these numbers had won 262 times (25.6%)
Any 3 of these numbers had won 340 times (33.2%)
There were only 5 instances when none of these numbers had won. Therefore, 1019 out of 1024 draws, the chance of, at least, one of these numbers to win is 99.5%;
The chance of winning a price is 73%.
The chance of winning a jackpot is 2%.

Sounds good? Yes, but the drawback is that you need to play 475,020 combinations each time; and this will cost you ₱9.5 million pesos every time you play. Hmm! Perhaps, there's another way. (Note that these figures were true only in 2022. For an updated list of the top 29 winning numbers, see the previous chart Fig 2.1.)

Top vs Bottom Numbers

Standard 02

Let's look at the data just presented from a different perspective.

All bottom numbers made it to the jackpot only 5 times, a 0.5% probability. Choosing all bottom numbers, therefore, is not advisable.
A mix of 3 top numbers and 3 bottom numbers is the most probable with a 33% chance of winning.
Second to the 3:3 top:bottom ratio is either: 2 top numbers and 4 bottom numbers (20% probability); or 4 top numbers with 2 bottom numbers (25% probability).
Having 5 bottom numbers or 5 top numbers in your combination is possible to win but at very rare chances (at 6% and 12% probability respectively).
To increase your chances to 79%, play 3 combinations following these top:bottom combination ratio: 3:3, 2:4, 4:2.

Observation

It's not every time that the top winning numbers win. Most frequently, the winning numbers are spread through top to bottom. Moreover, though the same numbers remain mostly on top, it does not mean that they remain active. There were periods when top winning numbers hibernate; not winning for a longer period. Thus, it may be necessary that we look at top winning numbers at current time and shorter periods. We will analyze that further in later chapters.

Try This Exercise

The objective of this exercise is for you to observe how numbers behave randomly. It is up to you whether you wish to actually play your numbers; or just observe. Using Fig 2.2 under Winning Performance Rates of Each Number, combine 6 lotto numbers.

When picking the numbers you intend to play, pick through top to bottom numbers. Pick 1 number from each group. Do not pick uniformly. Think random.
Form a second combination. This time, pick 2 lotto numbers from one group and one each from any four of the remaining groups leaving one group with no chosen number.
Find out in the next draw how many of your numbers had won.

How To Do It Manually

Without the aid of a spreadsheet program, you can do your own analysis with just a pen and a paper.

List the actual lottery results from the most recent 21 consecutive draws.
For each lotto number, count how many times it has won.
Mark the top 29 numbers. It can be more than 29 or less depending on how many numbers would tie in one place.
Further divide the top 29 into 3; and the bottom numbers into 3 as well to form six groups.
For each group, select one number to make a combination. An option is to pick 2 numbers from one group and one each from any of the remaining groups.
To analyze further, for each succeeding draw, mark the winning numbers on your list, say with a stick or an asterisk, whatever you wish. In time, after 3 or more draws, you will find out which of the six groups are frequently producing the winning numbers.

In A Nutshell

The numbers that usually win are not all the time from the top numbers, i.e., the numbers that have won most. Bottom numbers also win from time to time; and mostly often, those in between. A good combination is usually a mix of top and bottom numbers. You have 3 options: 3 tops and 3 bottoms; 2 tops and 4 bottoms; 4 tops and 2 bottoms. This does not mean however that 5:1 ratio – 5 tops and 1 bottom; or 1 top and 5 bottoms – is not possible. It's just that it rarely happens.

Notice also, in Fig 2.2, The Performance Rates of the 58 Numbers, the probability rates are very close to each other. We can deduce, therefore, that the individual probability of each number to win appears no longer substantial. An alternative is look at its performance rates. In later chapters, we will explore the significance of quantiles and how each group of homogeneous data can help in determining the potential winning of each number.

Algorithm 01, 02, 03 for Programmers

If you have programming skills and wish to develop an application related to lotteries, your first algo (01) is to count the number of times each lotto number wins. To make your frequency data more significant, convert your frequency data into percentile ranking (algo 02) and then group them into deciles (algo 03).2

Deviation From Theoretical Probability

Just Curious

Theoretical Probability vs Empirical Probability

We have discussed previously about the difference between theoretical and empirical probability. Following is just a review.

There are two types of probability: empirical and theoretical. Empirical probability is based on historical data. It is about the past, or what just happened. Theoretical probability is based on what is given; it remains constant regardless of historical data.

To illustrate:

With 6/58 lottery system, there are 58 balls. From 58 balls, 6 balls are drawn as winning numbers. So, what is the chance of each ball being drawn among the six? To calculate, we divide 6 by 58. The result is 10.34%—that's the theoretical probability; which means every ball has 10.34% chance of winning. This chance does not change. For every draw, each ball will always have that 10.34% chance of winning.

What's the significance of the theoretical probability?

By comparing the empirical probability with the theoretical probability, we would be able to determine, in the case of this lottery, which of the numbers are performing well. If the empirical probability is greater than the theoretical probability, it means that the number is over-performing its theoretical probability. On the other hand, if it is less than the theoretical probability, it means that it is lagging from its normal performance.

Which numbers are lagging, so far?

Based on 7,062 balls drawn from 1,177 draws, the following table summarises the attribute of a number that usually win from every draw.

Data Just Above Explained

Empirical probability rate of each number. The winning frequency of each number was calculated, then divided by the total number of drawings. The sample data were taken from 1,177 draws, year 2018 up to 2026.
For each empirical probability rate, the theoretical probability rate of 10.34% was deducted. The results are differences from -0.051 to +0.0325. See columns From – To. Though, this is not the proper way to measure the numbers's performance rates, let's see what we will find out.
The results are grouped by a range of values as presented on the table as From – To.
All deviation values that fall under the same range are counted, and its percentage calculated (%).

Observation

Numbers that usually win are those that deviate from 10.34% by only 0.01 positive or negative with a total rate of 63.9%. See the range -0.01 to 0 and 0 to +0.01.
Numbers that deviate from the normal (which is 10.34%) by less than 0.02 or greater than -0.02, usually win at 16.2% and 14.5% respectively.
All in all, 94.5% of the winning numbers commonly deviate from the normal probability by -0.02 to +0.02.
The catch: As the volume of the data grows bigger, the deviation values get much closer to zero. In time, all deviation values of all numbers will be equal to 10.34%. In later chapters, you will learn about this deviation using a smaller sampled data.
Negative vs positive: 2 to 4 negative deviation or 2 to 4 positive deviation are the most common values of each winning combination with 78.76% probability. All positive or all negative values share less than 2% probability. Five positive values or five negative values share less than 10% probability.

Suggested Approach To Choosing Your Numbers

The objective of this approach is to make it easier for you to choose the numbers that you wish to combine; not to give the absolute winning numbers, but only the potentials. With this approach, you simply eliminate the lotto numbers with lesser potentials.

Refer to Fig 2.2 presented previously.
For each group, find two deviation values nearest the zero, one negative and one positive. Mark your choices by group number.
From the 6 groups you have chosen, eliminate two groups.
From the remaining 4 groups of your choice, pick 2 groups. From these 2 groups, eliminate a number from each group. As a result, you will have a 6-number combination. Your combination should either have 4 negative values or 4 positive values or 3 negative and 3 positive.

Let's summarize, so far

Standard 01 says that none of the winning combinations has won more than once; not twice, not even more—only once. Therefore, when choosing the numbers that you wish to play, your combination should be something that has not won ever.
Standard 02 says says that most winning numbers are a mix of top performing numbers and those that are not performing well.

CH 3

Low vs High Numbers

Which numbers win most: 1-29 or 30-58?

Most people play numbers of important dates such as birthdays. For that reason, their combinations are mostly low numbers 1 - 31. If you’re playing only low numbers, what are your chances of winning?

At this point, you already know that winning numbers are usually a mix of top and bottom numbers. Though playing only the top 29 numbers may appear promising, it is not practical for the reason that you still have 29 numbers to choose from. So, what if, there is a way to narrow down your choices of numbers. This chapter looked at the winning probability of low versus high numbers.

Standard 03: Low To High Ratios

Which Numbers Are Low or High

First, let us define which numbers are to be considered low or high.

The lottery system 6/58 uses 58 balls numbered 1 to 58. Divide 58 into 2, the result is 29. So, the first half ⎯ 1 to 29 ⎯ are the low numbers while the second half ⎯ 30 to 58 ⎯ are the high numbers.

The following chart is based on more than 1100 results (PCSO's Ultra Lotto drawings from 8 Feb 2015 - 2023 (or up to any recent date as stated previously). It reveals whether most jackpot numbers are made of all low or all high numbers; or a mix of low and high numbers. If a mix, how many numbers should be low and how many numbers should be high?

Fig 2.4 Low To High Numbers Ratios

Based on the chart you just saw, the ratio of low to high numbers is best at 3:3 followed by 4:2 and 2:4 ratios. This means, that at 79% (in 2023; 80.7% in 2025) probability, your numbers are best if they are a mix of (figures may change as records are updated):

3 low numbers and 3 high numbers
4 low numbers and 2 high numbers
2 low numbers and 4 high numbers

Playing all low numbers (1 - 29) gives you a chance of only 0.8% in 2023 (1.46% in 2025). In 2018, it was 2.3%. Likewise, playing all high numbers (30 - 58) gives you a chance of only 0.95% in 2025 (1.5% in 2023); in 2018, the probability was 1.3%. It is possible to play all low or all high numbers but the chances are very rare. All low numbers occurred only 20 times in 2025 (16 times in 2023); while all high numbers occurred only 13 times in 2025; 9 times in 2023.

Playing 5 low numbers, on the other hand, or 5 high numbers gives your numbers a chance of winning by only 9.7% and 8.6% respectively (in 2023). In 2018, the ratios were 8.6% and 8.9%. On record, 104 of the 1,074 jackpot numbers contained 5 low numbers; while there were 92 jackpot numbers that contained all 5 high numbers.

The following was the result of the same study done in 2018. Four years after, the probable ratios have remained the same ⎯ 3:3, 2:4, 4:2.

Low : High Numbers Ratio
Low	High	Freq	Prob
0	6	5	1.3%
1	5	35	8.9%
2	4	89	22.6%
3	3	119	30.2%
4	2	103	26.1%
5	1	34	8.6%
6	0	9	2.3%
		394	100%

These probability ratios, most likely, would remain the same, no matter how much quantity of records (draw results) we add to the database. This is true based on the principle of the Law of Large Numbers.

More About Low and High Numbers

Now that you know that the common lottery 6/58 winning result is a mix of 2 to 4 low and high numbers, your next question in mind, perhaps, which number should be a low or a high one. The following table determines which ones are your low and high numbers. (This assumes that your numbers in a combination are arranged lowest to highest.) These data, which were based on 2018 study, may have little significance, but just out of curiosity, you may take a look.

Which numbers are low or high?
	1st	2nd	3rd	4th	5th	6th
Low	389	354	265	146	43	9
High	5	40	129	248	351	385
% Low	99%	90%	67%	37%	11%	2%
% High	01%	10%	33%	63%	89%	98%

The low-high probability rates in the above table are easy to remember. When forming your combinations, just follow these rules (assuming that your numbers were in lowest to highest order).

Your very first number and your second number should be a low number (1 - 29). The probability that it is a low number is 99% and 90% respectively.
Your 5th and 6th numbers should be a high number (30 - 58). The probability that it’s a high number is 89% and 98% respectively.
Your 3rd and 4th numbers can either be a low number or a high number. The 3rd number is more often a low number (at 67% probability) than a high number (at 33% probability); the 4th number is more often a high number (at 63% probability) than a low one (at 37% probability).

You can also observe these patterns. There are only 3 patterns that you have to remember. L means low; H means high.

Common Low-High Patterns
Ratio	1st	2nd	3rd	4th	5th	6th
3:3	L	L	L	H	H	H
2:4	L	L	H	H	H	H
4:2	L	L	L	L	H	H

However, we do not exclude the possibility of 5 or 6 low or high numbers to win a jackpot. In 2023 study, based on 1,153 results, 20.38% of the results contain either 5 or 6 low or high numbers; which is equivalent to 235 results. This rare combination of low and high numbers may repeatedly happen within 28 draws of not occurring. To capture the possibility of jackpot numbers to produce 5 or 6 low or high numbers, playing 4 low or 4 high numbers in your combination would do the trick because in such case, you would have matched 4 of the low or 4 of the high numbers.

Timing of Low:High Combinations

Yes, 3 low and 3 high numbers are the most probable combination; however, we cannot disregard that the 2:4 or 4:2 combinations are also possible. So, the next question is: when do you play 3:3, 2:4, 4:2 or even the 5:1 or 1:5 ratios?

The following data reveal when the probable ratios ideally win.

Fig 2.5 Occurrence of Low:High Number Combinations

Three low numbers, three high numbers combination (3:3). This ratio usually occurs immediately draw after draw. In other cases, it will occur after one draw of not occurring. Generally, this ratio can occur within 1 to 6 draws as shown by the Elapsed Time values. Rare instances would be within 7 to 11 draws. What this is saying is that, say, today the winning combination was 3 low numbers and 3 high numbers. In the next draw, it may occur again; or it may occur after 2 draws of non-occurrence. In rare cases, it may not occur for a longer period such as 7 - 11 draws of non-occurring. During those days of non-occurring, the other ratio probabilities occur.
Four high and 2 low numbers, or 4 low and 2 high numbers combination (4:2, 2:4). Likewise, these ratios can possibly occur within 1 to 6 draws but at a slightly lower probability. Their non-occurrence can extend within 7 - 10 draws. There is a possibility that these ratio patterns may not occur within 11 - 16 draws but most probably not longer.
Five or six low numbers or five or six high numbers (5:1, 1:5, 6:0, 0:6). These are the low:high combinations that rarely occur. Though they can occur again within a shorter period but most likely their next occurrences may take even longer than 38 draws of not occurring. In other words, once any of these ratios occurred, it may take up to 38 draws of not occurring.

To apply this probability standard, combine your numbers following these ratio 3:3, 4:2 or 2:4. If you prefer to be adventurous, play the other ratios as well. Observe however, that if recently, the winning combinations contained 5 or 6 low numbers or 5 or 6 high numbers, stick to the most probable ratios instead.

Specific Low and High Number Patterns

The low to high number ratios discussed previously ignore the actual positions of both the low and high numbers in the order they were drawn. This may be difficult to observe when combining your numbers for the reason that this method is tedious. Anyway, let me present the data.

The total number of unique 6 low-high sequences that can be formed with either low or high number or both is 64. In other words, we are looking for 6-character patterns that contain only L and H. The following chart gives you an idea which low-high pattern usually yield positive results. The chart does not show all the 64 patterns due to lack of space; but hovering on each bar reveals the details.

Fig 2.6. Frequency of Specific Low and High Number Sequence

For now, you can still see the variances between each pattern. In time, as the database grows, the variances will become minimal as they reach the average rate, which is 1.56% or 1/64 (Law of Larger Numbers).

How to apply the data

With the Law of Larger Numbers in mind, consider betting on the patterns with lower rates, that is lower than 1.56%. In time, these lower rate patterns will eventually reach its goal of 1.56%. It is for that reason that these lower rate low-high number patterns are more likely to occur compared to those higher rate patterns.

To illustrate.

Assuming the pattern LLHHLL has a frequency rate of 3.14%, it is most likely that its frequency will become dull. Meanwhile, the other patterns will try to catch up until every pattern goes closer to 1.56%, higher or lower. For that reason, you might consider instead HHLLHL, which has only 1.46% frequency rate.

Odds of Winning After Eliminating the Least Probable Low-High Combinations

The least probable low-high combinations are:

6 low numbers
6 high numbers
5 low numbers
5 high numbers

These types of combinations comprise 7,837,830 combinations. By eliminating these least probable combinations from the total possible combinations of 40,475,358, your odds of winning for playing one combination only increases from 0.00000247% to 0.000003064%. So, the number of probable combinations now after eliminating the least low-high probable ones is 32,637,528.

Try This Exercise

You've learned so far about the probability of top-bottom numbers and probability of low-high numbers. Now, try to make a combination using the data presented in Chapter 2.

Combination 1 (3:3 ratio)

Step 1. Following the 3:3 ratio, pick one low number and one high number from the top numbers. For example:

6 • 34

Step 2. Pick one low number and one high number from the bottom numbers.

18 • 39

Step 3. Pick another number from the top number and one from the bottom number. One must be a low number and the other must be a high number.

43 • 29

Your final numbers are:

06 • 18 • 29 • 34 • 39 • 43

Combination 2 (2:4 ratio)

Do Steps 1 and 2. In step 3, this time, pick two low numbers - one from the top and one from the bottom numbers. For example:

14 • 26

Your second combination:

06 • 14 • 18 • 26 • 34 • 39

Combination 3 (4:2 ratio)

Do Steps 1 and 2. In step 3, this time, pick two high numbers.

54 • 47

Your 3rd combination:

06 • 18 • 34 • 39 • 47 • 54

In A Nutshell

So far, the standards that we have established, when combining your lotto numbers, are:

Standard 01. Your own 6-number combination should have not won before.
Standard 02. Your numbers should be a mix of top winning and bottom winning numbers. Refer to the Fig 2.2 for the list of top and bottom numbers.
Standard 03. Your numbers should be a mix of low and high numbers using the high probable ratios of 3:3, 4:2, or 2:4. If you prefer to be more adventurous, play the 5:1 or 1:5 ratio (probability of 9.68% and 8.57% respectively)
The all high numbers occurred only 9 times (0.84% probability); while the all low numbers occurred only 16 times (1.49% probability).

Note: Figures and rates may have changed as records are updated; that is, as new results are added to the database. On the other hand, with regard to the Law of Large Numbers, in time, the probability rates may just slightly change. The charts may present the most recent data based on the date stamped in Chapter 1 of Part II.

Algorithm for Programmers

Algo 04. For each decile group, identify the low and high numbers. When generating a combination, produce 3 combinations with either 3 or 2 low numbers.
Algo 05. As you input the winning lotto numbers,

(1) Identify which numbers are low (1 - 29) or high (30 - 58) to come up with a low-high sequence. For example, LHLHLH.
[2] Store this low-high sequence on a separate field on the results database.
[3] Run a process that will count similar sequences. For example, how many so far in the results database have the same LHLHLH pattern?
[4] Store the result (instances of the same pattern) on a separate field of the LowHigh table.
[5] As the LowHigh table is updated, update likewise, its probability percentage.

Guide for Spreadsheet Users

On the Results tab, determine the low-high sequence of each winning combination. Input this formula beside each winning combination. (For readability purpose, spaces were added in the formula; these spaces should be omitted on your spreadsheet):

IF (B3<30,"L","H") & IF (C3<30,"L","H") & IF (D3<30,"L","H") & IF (E3<30,"L","H") & IF (F3<30,"L","H") & IF (G3<30,"L","H")
Copy the formula up to the last row of winning combination.
B3 to G3 refers to the winning lotto numbers. L stands for low; H stands for high.
Result is concatenated string of Ls and Hs.

On the Tables tab, create a table that contains all the possible LH sequences. Beside each sequence, the count of all exact sequences are stored. On its side, calculate the probability rate of existence.

To count all the same sequences present in the Results database, input this formula:

=COUNTIF (Results!J$3:J,A3) where J$3:J contains the LH sequences; and A3 refers to form of sequence in the LowHigh table.

To calculate the probability rate, input this formula: =B3 / sum(B$3:B) where B3 is the value of count; and B$3:B is the column where all the values of count are stored. The function of the formula is to divide a specific value of count by the sum of all counts.

Odd vs Even Numbers

Which numbers win most: odd numbers or even numbers?

The superstitious may prefer odd numbers over even numbers, or vice versa. But actually, superstitions have nothing to do with odd numbers winning over even numbers, or the other way around. However, statistics may reveal which type of number wins mostly: odd numbers or even numbers.

Odd-Even Winning Probability

The following study both contain data from 2018 and earlier; and 2022 and earlier. In 2018, the study covered only 441 drawing results. The probability findings for odd-even patterns were significant then. After four years, 583 actual lottery results were added to the study increasing the subject of the study to 1024 drawing results.

Findings in 2022

After studying 1024 drawing results, the odd-even patterns are no longer significant. In other words, any odd-even combination pattern is as good as the other with probability rates ranging from 0.68% to 2.64%.

The probability for the number of instances, however, remain the same with 3:3, 4:2 and 2:4 as the common odd-even ratio. If you feel being adventurous, also try 1:5 or 5:1. This is also possible, but it rarely happens, with probability rates of 8.7% and 7.5% respectively

The following pie chart gives the rest of the data. Data here are updated from time to time; thus, you might find the figures mentioned in the preceding and succeeding paragraphs inconsistent with the figures of the chart.

Fig 2.41 Probability of Odd : Even Ratios

The 2018 Study on Odd-Even Winning Probability

In order to come up with significant probability of odd-even patterns, each result studied was arranged numerically from smallest to the largest number.

Highlights

The odd-even probability is useful if your numbers are arranged numerically from lowest to highest.
If your goal is to make all 6 numbers right, playing all odd numbers or all even numbers do not give you better chances of winning.
The most probable ratio of odd to even are 3:3, 2:4 and 4:2.
If your numbers contain 5 odd numbers or 5 even numbers, consider shifting them to 2:4 or 4:2 pattern.
Doubles (2 odd or 2 even numbers next to each other) are as popular as odd and even next to each other.

Major Odd-Even Patterns

There are seven (7) major odd-even patterns.

Six odd numbers
Six even numbers
Five odd numbers, 1 even number
Five even numbers, 1 odd number
Four odd numbers, 2 even numbers
Four even numbers, 2 odd numbers
Three odd numbers, 3 even numbers

Which of the patterns just mentioned commonly win?

Standard 04. The Odd-Even Probability

3:3 Odd-Even Ratio

If your combination has 3 odd numbers and 3 even numbers, you have a better chance of winning compared to all-odd numbers or all-even numbers. The probability that a result would have 3 odd numbers and 3 even numbers is 33.7% (36.5% in 2018).

4:2 & 2:4 Odd-Even Ratios

If your combination has 4 odd numbers and 2 even numbers, most likely your numbers can win by 25.1% probability. If your combination has 2 odd numbers and 4 even numbers, your odds of winning is 22.3%.

1:5 & 5:1 Odd-Even Ratios

If your combination has 5 odd numbers or 5 even numbers, your chance of winning is a low 7.2% probability and 8.8% probability respectively. If you notice that your combination has this pattern ⎯ 5 odds or 5 evens ⎯ might as well change one of the odd numbers to even; or change one of the even numbers to an odd number to increase your chance of winning. The 5 odd numbers or 5 even numbers may rarely happen but they remain possible.

All Odd or All Even

Playing all odd numbers or all even numbers are the patterns that you can ignore because together they make only a probability of 2.8%.

Odd-Even Patterns or Sequence

Update.

As the database of results being tested grow larger, the odd-even patterns probability have become insignificant; or rather not showing significant changes at all. The Law of Large Numbers state that the larger the sample size is, the closer it gets to its average. There are 64 odd-even patterns. Assuming each pattern are occur equally, the average probability is 1/64 or 1.56%. If only a few results are being tested, we would see great deviation from the average. Some patterns may occur at 25% while others at 0%. However, as the number of results being tested grow larger, each pattern gets closer to 1.56%.

For the sake of presentation, below is a screenshot from my worksheet showing the top odd-even patterns. Notice that the highest probability is only 2.49%. The lowest (not shown) is only 0.73% for the pattern EEEEOO. In due time, all patterns will reach the average 1.56%.

Early Probability Results for Odd-Even Patterns (Prior to 2025)

Perhaps, you’re wondering which of your numbers should be odd or even and in what order. Should your first number be odd or even? What about the 2nd, 3rd, 4th, 5th and 6th?

The answer is any of your numbers can be odd or even because the probability of any number to be odd or even, without regard to ratio, is almost the same; ranging from 48%-53%. Therefore, the chance of a winning number to be odd or even is almost 50:50.

However, by eliminating what’s not probable, we would be able to zero in the patterns that are most probable.

Alternating Odd and Even Numbers

Starting with the alternating odd-even patterns (eg OEOEOE or EOEOEO), results show that this type of pattern does not frequently happen. Its probability is only 6.1%. So, might as well avoid this type of pattern. [In 2025, these patterns were the most common at 2.49%%.]

Straight Odd vs Straight Even

OOOOOO or EEEEEE: Six (6) odd numbers straight or 6 even numbers straight. This pattern has occurred only 2.5% of all the results. You can avoid these patterns. [ In 2025, the probability were 1.3% and 1.1% respectively.]
OOOOO or EEEEE: Five (5) odd numbers straight or 5 even numbers straight. This type of pattern has occurred only 2.8% of all the results. If we add the 6 straight patterns, the probability of having straight 5 odd or even numbers becomes 5.3%. [ In 2025, the probability for this type of pattern were 7.5% and 8.7% respectively.]
OOOO or EEEE: Four (4) odd numbers straight or 4 even numbers straight. This type of pattern has occurred only 13.5% of all the results. If we consider the 6 and 5 straight patterns, the probability of having 4 straight odd or 4 straight even numbers is 18.8%. [ In 2025, the probability of 4 odd numbers occurring was 24.4%; of 4 even numbers is 2.5%.]
OOO or EEE: Three (3) odd numbers straight or 3 even numbers straight. This pattern has occurred 35% of all the results. The probability however, of having 3 straight odd or even numbers is 53.8%. On the other hand, there is also a probability that such pattern cannot exist at 46.2% probability. This means that your combination may or may not have this type of pattern. [ In 2025, the probability for this type of pattern was 34.6%.]
OOOEEE or EEEOOO: This type of pattern (double straight 3 odds and evens) has occurred only 3% of all the results. You can avoid this type of pattern. [As of today, the probability for these patterns are 1.56% and 1.17% respectively.]
Doubles or 2 Odds or 2 Evens Straight: The probability that 2 straight odds (OO) or 2 straight evens (EE) to exist is 93.9%. This means that, at least, one double can exist in most every result. The chance that such pattern does not exist is only 6.1%. [As of today, having the most common type of pattern, its probability ranges from 0.88% - 2.44%. ]

1 Double. OO or EE. A single double can exist at 47.5% probability. Related patterns are OOEOEO, EOOEOE, OEOOEO, EOEOOE, OEOEOO, EEOEOE, OEEOEO, EOEEOE, OEOEEO, EOEOEE.
2 Doubles. OO OO or EE EE or OO EE or EE OO. Two doubles can exist at 44.4% probability. These doubles can exist in any order. Related patterns are EOOEOO, OEEOEE, OOEEOE, EEOOEO, OOEOOE, EEOEEO.
3 Doubles. This type of pattern is rare. It has occurred only at 2% of all the results. Related patterns are OOEEOO, EEOOEE, OOOOEE, EEEEOO, OOEEEE, EEOOOO.

You don’t have to memorize all these patterns. Just remember that there can only be one or two doubles in your combination. The rest of the numbers should be alternating odd-even or even-odd. [As of 2022, any odd-even pattern is as good as the other.]

In A Nutshell

To this day 2025 and onwards, as the probability patterns reach their common average of 1.56%, any odd-even pattern is as good as any other.
Prior to 2022, the following were the results of the study when the sample size tested was still small. As of 2025, they are no longer relevant.

There are 64 possible odd-even combinations or patterns. These patterns are applicable only if the numbers in your combination are arranged in ascending order (lowest to highest number).
The 3:3, 4:2, and 2:4 ratios are the most significant ones among the seven (7) odd-even ratios. Together, they comprise 81.1% in 2022 (82.7% in 2018) of all the results studied. So, when forming your combinations, limit your numbers to these odd-even ratios.
Though the ratios 5:1 or 1:5 is rare, it is possible.
The all odd or all even numbers combination is also possible but with very low chances (both at 1.3% probability). Both have occurred only 14 times out of 1074 draws.
Two consecutive numbers may either be both odd or both even or one odd and the other even. The patterns OO, EE, OE, and EO share almost equal probability.
Your combination should have one or two doubles (2 straight odds or evens). The remaining numbers should be alternating odd and even. [This is no longer true as of 2022.]
3 odd numbers straight or 3 even numbers straight are also common at 50:50 chance.
If you wish to play only the most probable 88% patterns, you can avoid these patterns: OEOEEE, OEEEEO, EOOOOE, OEEEOO, EEEEEO, OOOOOE, EEOOOO, EEEOEO, OEEOOE, EEOOEE, EEEEOO, EOOOOO.

Algorithm for Programmers

Algo 06. Have a separate table with two fields for odd-even sequences. The first field stores the odd-even sequence; the 2nd field stores the count of sequences present in the results database. Let's call this table tblOddEven. There are 64 odd-even combination sequences. Each time you enter a new result, determine the odd-even pattern; then add this occurrence to tblOddEven. To initially populate the table, run a process that reads the Results database; determine the odd-even sequence; than update the OddEven table.

For Spreadsheet Users

In the Results database, add a new column to store the odd-even sequence. Use this formula: =MAP(B3:B,C3:C,D3:D,E3:E,F3:F,G3:G, LAMBDA(a,b,c,d,e,f, IF(ISODD(a),"O","E") & IF(ISODD(b),"O","E") & IF(ISODD(c),"O","E") & IF(ISODD(d),"O","E") & IF(ISODD(e),"O","E") & IF(isodd(F),"O","E")))
Input this formula beside the very first record of Results database and let it do the sequencing for the rest of the results. Each time a new result is added, the sequence is automatically written.
On a separate sheet, create a table that contains all the possible odd-even sequences.
- On the first row under Pattern, add this formula: =SORT ( UNIQUE ( FILTER ( Results!K3:K, Results!K3:K<>"")), 1, TRUE). This formula will extract the odd-even sequences on the Results database with duplicates eliminated.
- Beside each sequence, enter this formula to count the occurrences of same odd-even sequences: =COUNTIF ( Results!K$3:K, E3 ). Copy this formula up to the last record.
- In the 3rd column, enter this formula to calculate the probability rate: =F3 / SUM ( F$3:F ). Copy the formula up to the last record.
- Each time a new result is added, the odd-even table is automatically updated.
Note that spaces are added in the formula for readability purposes. In actual spreadsheet, the spaces are not necessary. Following is a sample of the table.

Span And Bounds

All are possible but not all are probable

It is true that any 6-number combination is possible, but not all are probable, at least, not just yet. For example, 1 • 2 • 3 • 4 • 5 • 6 is a possible combination because such can definitely exist. However, statistically, with PCSO's Ultra Lotto 6/58, it's not just yet. In case, it has happened, most likely, it won't occur twice.

Setting The Bounds

Winning numbers usually come from within a probable range

The total possible 6-number combinations that you can form out of 58 numbers from 1 to 58 is 40,475,358. All these combinations are possible but not all are probable.

By arranging each result from lowest to highest number, statistics has revealed that certain numbers do not win at certain positions. For example, in the first position, common winning numbers are from 1 to 16 with a probability of 93%. If you want to consider 100% probability, then you have to consider all the numbers up to 45 even if such number has won only once.

Frequency of Winning Restrained To Positions

Data 09 presents the calculated frequency of winning of each lotto number in the ordered position to establish the probable range as to which number should be the smallest in a combination and which number should be the largest. For example, in the combination 06 • 07 • 10 • 21 • 34 • 51 in numerical order, the number six (06) is in the 1st position because it is the smallest number; while #51 is in the 6th position because it is the largest number. The rest of the numbers take their positions as 2nd, 3rd, 4th and 5th.

The next question is: Is there a rule as to which number should be the smallest and the largest in a combination?

On record, the smallest numbers that were formed in winning combinations were numbers 01 - 45; which means numbers 46 to 53 cannot (yet) your smallest number in your combination. If you want to achieve only 99% probability, your smallest numbers can only be within the range 01 - 30. On the other hand, your largest number in a combination can only be within the range 21 - 58. To limit your probability to 97.3%, your largest number can only be within 34 - 58. Note that #01 will always be the first number in any combination. It can never be the 2nd, 3rd, 4th, 5th or 6th because it is the smallest of all numbers 01 - 58. Likewise, #58 will always be on the 6th because no number is larger that 58 in a lottery system 6/58. Number 02 can only either 1st or 2nd; while 57 can only be 5th or 6th. Numbers 03, 04, 05 are also limited up to 3rd, 4th and 5th positions respectively. Numbers 54, 55, 56, 57 and 58 can never be the smallest number in a combination. All other numbers can either be at 1st, 2nd, 3rd, 4th, 5th or 6th position.

To illustrate:

If your combination is, 47 • 49 • 50 • 52 • 55 • 58, the probability of this to win is 0% for the reason that, on record, no combination has won yet where the smallest number is 47. On the other hand, if your combination is something like 02 • 06 • 12 • 17 • 18 • 20 where #20 is the largest, the probability for this to win is also 0%. These findings are based on 2025 study. If ever, in the next few years, that 0% probability may change to 0.1%.

There are also other numbers, at this time of study (2025), that have 0% probability if it is in the 2nd, 3rd, 4th or 5th position. For example, numbers 49 - 54 have not won yet as the 2nd smallest number in a combination. Also, numbers 05 - 12 have not won yet if they are the 2nd largest number.

Following is the result of the 2025 study that presents the probability of each number to win in the ordered positions. These figures may change as new results are added to the database.

Fig 5.1 Frequency of Winning In The Ordered Position

To understand the data just above, if a lotto number has a zero value on a particular position, it means that it is unlikely to win at 0% probability. If the value is 1, it has a 0.1% probability.

Probable Number Span (Standard 05)

The data just presented is summarised in the table that follows. It presents the most probable winning numbers in the ordered positions, or what is referred hereto as the probable winning range. These ranges of lotto numbers excluded those that had only less than 2% probability. These data are based on 1373 ~~337~~ ~~386~~ results covering up to 2025. This standard may be constant long-term but may change eventually after a number of years as the volume of data increases.

Position >>	1st	2nd	3rd	4th	5th	6th
Lowest	1	3	10	22	32	43
Highest	16	25	39	46	56	58
Prob%	88%	84%	87%	76%	86%	87%

The data above serve as bounds (lower and upper limits, or probable winning range) that can guide you when forming your combinations. For example, the lowest number in your combination should be between 1 and 16. For the second position, your next lowest number should be between 03 and 25, and so forth and so on. However, we cannot set this lower and upper delimiters as standard because the probability can still change as new results from the lottery are added.

Taking the Risk of Choosing Numbers Beyond The Limits

Of course, you can take a risk of including one number outside the bounds because it is still a possibility thought not yet positively probable as of this time.

Perfect and Extraordinary Combinations

A perfect combination would be when all the 6 numbers in a combination are within the probable winning range. However, not all results are perfect. Based on 389 results, 67.9% were perfect combinations; the rest, referred to as extraordinary combinations, had only 3 to 5 numbers winning that were within the probable winning range. An example of a perfect combination is the 26 Dec 2017 result which was 09 • 22 • 35 • 41 • 44 • 46. The 31 Dec 2017 result ⎯ 06 • 14 • 15 • 24 • 25 • 43 ⎯ showed 1 number, which is 25, outside the limits (outside the range of 32-56).

So, how likely that a winning result would be within the probable range?

The table that follows shows how much of the actual results were within the probable range. There's almost a 70% chance that all 6 winning numbers would be within the probable range; about 91% chance that 5 numbers would come from within the range; and 97% chance that 4 numbers would come from within the range. (Prior to 2025)

Numbers Within Bounds	Occurrences	Prob
6	168	67.9%
5	90	23.1%
4	24	6.2%
3	11	2.8%
2	0	0%
1	0	0%
0	0	0%

Which column usually plays within bounds?

Which column in the ordered positions usually give a winning number within the probable range?

The probable range of numbers in the 1st to 5th positions usually give a winning number at 81% - 88% probability. The probable range in the 6th position usually gives a winning number at 92.6% probability.

Significance of Setting These Limits

By eliminating what's not probable, setting the lower and upper limits have reduced the number of possible and probable combinations to just about to 1.6 million or 0.0000616% probability rate. That's already good news compared to 40.4 million combinations.

In A Nutshell

Picking your 6-number combination from the probable range gives you a ~

49.9% chance of winning the jackpot;
77.5% chance of winning 5 numbers; and
91.2% chance of winning 4 numbers.

Form your lotto combination in a numerical order from lowest to highest number. Statistically, winning numbers come from a select range of numbers. Presented below are the probable ranges at 99% probability; and 86%-91% probability, if you want to ignore those numbers that had less than 2% chance of winning.

Your	Probable Range
Combination	93%-97% Prob	76%-88% Prob
1st number (smallest)	01 - 20	01 - 16
2nd number	02 - 35	03 - 25
3rd number	09 - 43	10 - 39
4th number	13 - 52	22 - 46
5th number	23 - 56	32 - 56
6th number (largest)	38 - 58	43 - 58

Tip & Strategy

Play 9 combinations as follows:

5 combinations where all 6 numbers are within the probable range
3 combinations where all 5 numbers are within the probable range in which ~
- 1 combination contains your 2nd number that is outside the probable range;
- 1 combination contains your 5th number that is outside the probable range;
- 1 combination contains either your 3rd, 4th or 1st number that is outside the probable range;
1 combination where all 4 numbers are within the probable range except the 1st and 2nd numbers.

Algorithm for Programmers

Algo 07. Create a Bounds table with 6 fields: 1st, 2nd, 3rd, 4th, 5th, 6th.

Each time a new result is added, determine the smallest number in the combination, the 2nd smallest, 3rd, up to the largest number.
For each lotto number, search the Bounds table. If the lotto number already exists, no update is necessary. If it does not exist, add a new record.
Sort the Bounds table in ascending order each time it is updated.
Initially, you can populate the Bounds table by running a program that performs the same algorithm.

For Spreadsheet Users

Create a new tab sheet and call it Bounds as shown in the image below.
For each cell under the 1st column, add this formula: =COUNTIF ( BYROW( Results!$B$3:$G, LAMBDA(rowvalues, MIN(rowvalues))),$A3). This formula counts the frequency of the lotto number if it is the smallest number (MIN is minimum)
Under the 2nd column, add this formula: =COUNTIF ( BYROW( Results!$B$3:$G, LAMBDA(rowvalues, SMALL( rowvalues, 2))), $A3). This formula counts the frequency of the lotto number if it is the 2nd smallest number in the combination.
Under the 3rd up to 5th columns, add the same formula just preceded but change the value of SMALL( ROW VALUES, 2) to 3, 4, and 5 depending on the column you are working on.
Under the 6th column, add this formula to every cell: =COUNTIF( BYROW( Results!B$3:G, LAMBDA( rowvalues, MAX(rowvalues))), A3). This formula counts the frequency of a number if it is the largest number in the combination (MAX is maximum).

The Probable Number Gaps

Limiting Your Number Combination Based on Constraints

Is it possible to figure out which numbers can probably win based on restricting factors? You already learned, in the previous sections, that not all numbers are probable. Yet, there is still that challenge of picking the right numbers. By restricting further your method of combining or choosing the numbers that you want to play, you can narrow down your selection of numbers to the most probable ones. This time, you will learn about the distance factor, which is simply the difference between two consecutive numbers. Likewise with Bounds (Probable Range), we can establish these delimiters if we arrange each combination from smallest to largest number.

Did you know that your numbers have more chances of winning if the difference between two numbers is less than 10? That's the general rule. However, in every rule, there are exceptions, which will be explained here further.

Distances Between Two Numbers

Establishing The Value Differences Between Any Two Consecutive Numbers

Highlights

In the ordered position (smallest to largest) of your lotto numbers, if you subtract a lotto number from the next one, the calculated difference should be any from 1 to 41.
The smaller the value of the difference, the greater the probability.
If you sum up all the distance values of a combination, common values are any from 10 to 57. Any value outside these delimiters are improbable for now.
If you are playing numbers in multiples such as in multiples of 3s or 2s, etc, most likely they are not going to win, because as of this writing, nothing of that sort has won yet.
All winning combinations on record (based on 1375 results) consist of at least one distance value of 1 to 9. The others are mostly combined with 10 -19 or 20 - 29.
More than 50% of the winning combinations on record consist of unique distance values; while almost 40% consist of one duplicate values.

Setting the Standard

To determine the distance factors, each draw result must be arranged numerically from the smallest to the largest number. For example, the order of the 8 May 2018 result 19 • 27 • 07 • 46 • 18 • 53 would be re-arranged as:

07 • 18 • 19 • 27 • 46 • 53

Then, the difference between every 2 consecutive numbers are calculated. The value of the difference is referred to as the distance between 2 consecutive numbers; or simply distance. Thus, in the preceding example, the distances between the numbers are:

Distance AB = 18 – 7 = 11
Distance BC = 19 – 18 = 1
Distance CD = 27 – 19 = 8
Distance DE = 46 – 27 = 19
Distance EF = 53 – 46 = 7

You now have the distances:

11 • 1 • 8 • 19 • 7

If you sum up all these numbers, you get the sum of all distances:

11 + 1 + 8 + 19 + 7 = 46

The sum of all distances 46 is the same as the distance between the largest and the smallest number, thus;

Distance FA = 53 – 7 = 46 = Sum of all distances in that particular combination

With the numbers in a combination arranged from smallest to largest, A refers to the 1st number, which is the smallest. B refers to the 2nd number, which is the 2nd smallest; C is 3rd; D is 4th; E is 5th; and F refers to the 6th number, which is the largest. Distance AB (or B minus A) therefore, means the difference between the first and second number. Distance BC is the difference between the 3rd and 2nd numbers (or C-B); and so forth and so on.

Significance of the Distances

Our planets in the solar system maintain their orbits because of gravity. If one planet changes its force of gravity, it affects the orbits of all the other planets. Imagine the lottery balls as a group of small planets which maintain their positions based on alternating fixed set of distances. By determining the distances between 2 numbers, you can figure out the probable numbers next to another number.

For example, if the common distance is 12, then you would know that the probable next winning number after 21 is 33 calculated as follows:

21 + 12 = 33

where 21 is the given lotto number, 12 is the probable distance of gap, and 33 is the calculated next probable winning lotto number.

These values of distances, the sum of the distances included, form a set of delimiters. Delimiters act as constraints in such a way that they prohibit you from combining just any number of your choice. Delimiters ensure that your combination is within the probability zone.

So, how do you figure out the probable gap?

Probable Gaps Between Two Numbers (Standard 06)

As mentioned earlier, the differences between two numbers of every result were calculated. As a result, the following table presents a summary of the findings in 2025 covering 1,375 results.

Distance		Prob
From	To	%
1	9	65.02%
10	19	26.78%
20	29	6.60%
30	41	1.60%

Proof of Data

To give you an idea what the data look like, following is a screenshot of the calculated data on Google Sheets.

The first data table that you see, Distances Between Consecutive Numbers, calculated the distances or differences between the numbers of all the winning combinations. Column BA or AB would be 2nd number minus the first number. Column CB or BC would be 3rd number minus the 2nd smallest number; and so forth and so on. Remember that the winning combinations were re-arranged numerically smallest to largest in order to establish these constraints or delimiters.

Column Sum adds up all the values of the distances.

How often does a particular distance occur?

The second set of data, Distances Frequency & Probability, counted the occurrences of each distance value calculated under columns BA, CB, DC, ED, FE. As a result, recorded distances ranges from 1 to 41. No distance occur that is greater than 41. The value of occurrences calculates how frequent a particular distance is resulted from the winning combination.

Each value of occurrence is then divided by the sum of all occurrences to get the probability rate or percentage ratio. Notice that the highest percentage is 10.05%; the lowest, which is not shown, is actually 0.01% corresponding with the distance value of 41. To make the data more meaningful, the data were divided into four and are summarised above where distances of 1 - 9 make 65% of all outcomes. This means that if the difference between two of your lotto numbers is from the range of 1 - 9, then, your numbers are good, probability wise. On the other hand, if the difference between two consecutive numbers of your combination is greater than 41, might as well change the larger number to a smaller one so that it fits the probability zone. Any distance value of greater than 41 has 0% probability (for now). You can find the complete data, as a column chart (Data 10), in the next sections.

The probability of duplicate distances and sum of distances are discussed separately in this chapter.

How to apply this standard

If you are playing only one combination, applying this standard is easy with the use of a calculator; or mental subtraction would do just fine. However, if you plan to play 10 or more combinations, applying this standard may be tedious. Using a spreadsheet app may be handy.

If you do not want to keep a note of the summarised data above, just remember 1 - 41. The smaller the distance, the better; and do not exceed 41. As for the sum of distances, do not go beyond 10 - 57.

Visual View of Distance Frequency Probability

The following column chart presents all the probable distances and how often they occur in every draw. Note that the smaller the value of the distance, the greater its frequency of occurrence. The next question is: how small should the distance be: 1- 9? 10 - 19? 20 - 29? Let's start first from what it should not be.

Fig 2.61 Distances Frequency and Probability

The Risk Zone

The distances 24 to 41 can guarantee only 4.03% probability. This means that if the difference between two consecutive numbers is between 24 - 41 inclusive, there’s a little probability that your combination is likely to win. It is possible but it rarely happens.

For example, in this combination 01 • 42 • 50 • 53 • 57 • 58, the difference between 42 and 1 is 41, making this combination unlikely to win. To make it a probable combination, you can change 42 to any number between 22 and 37. This range ensures that your numbers are good both with #01 and #50.

If you want to take a risk, by all means consider any distance beyond 22 - 37.

The Safe Zone

If the differences between two consecutive numbers are between 1 and 23 inclusive, your combination has 95.97% chance of winning. Well, not exactly a better chance of winning; but rather, a better combination of numbers that aligns with the history of winning combinations.

Exploring More About the Distances

What if you limit your distances to a mix of 1 to 9 only? For example: On June 29, 2025, the winning combination was 14 • 36 • 17 • 22 • 34 • 29. Arranged smallest to largest, that is to be: 14 • 17 • 22 • 29 • 34 • 36. To subtract each from the next, the results are: 3 + 5 + 7 + 5 + 2; add them all up and the result is 22.

Distance values of 1 to 9 were present in all of the sampled results (1,375, as shown in the stats below); which means that every winning combination consisted of at least a distance value of 1 to 9. These distance values are the top 9 most common. But how many of the results actually consisted only values of 1 to 9?

Presenting the data. This is based on 1375 results studied. —

The figures under In Results refer to the number of winning combinations that consist of any distance value stated in the column Distance . The columns 5 to 1 breaks down the figure in In Results into number of instances falling within the same distance range. For example, of 1375 results, only 66 of those contain all 5 values within 1 - 9. One of these results won in 5/31/2015 with the numbers 35 • 37 • 45 • 51 • 52 • 54. Subtracting one from the next, you get the distances: 2-8-6-1-2, which are all within the range 1 - 9. The 0 column is the exact opposite or its non-existence in the results. Therefore, if 10 -19 were found in 1078 results, they were not found in 297 results.

Distance Value of 1 - 9

All winning combinations (1,375 all in all) consisted of at least one instance of a distance value that is less than 10; i.e. 1 - 9. So, it is safe to say, as a general rule, that your combination should consist of at least a distance of any value from 1 to 9.
At most, three instances of 1 - 9 is the most common; followed by four instances, then two.
Seldom that all five distance values are 1 - 9; it had occurred 66 times, though.
Very uncommon that only one instance of 1 - 9 is present in a combination. There were only 9 combinations that matched that criteria.

Distance Value of 10 - 19

The next most common distance values are 10 -19 which made 78.4% of all the results (1078 / 1375).
It is not probable that all distance values are any from 10 -19. (See row 10-19, column 5).
Having four of these distance values is possible but it rarely happens. Only 8 out of 1,375 results that such had occurred.
The most frequent scenario is to have one or two distance value of 10 - 19 be present in your combination. At other times, having three is okay.

Distance Value of 20 - 29

This is easy to remember. Your combination can only have an instance of any distance value of 20 - 29, making it 31.93% of all 1375 results. Having two is possible but not very probable.

Distance Value of 30 - 41

This is the rarest of all distances to occur. Its probability is only 7.56% for values 30 - 39; and 0.44% for values 40 or greater.

The next question is: Which of these values usually go with another? If the most common is to have three values of 1 - 9, what are the other two? Let's look at a different picture of the data.

Probable Combination of Distance Values

Following is a screenshot image of the data presenting how often a particular distance value go with another value.

You can see from the table below that the most common form of distance mix are: 32000, 31100, 41000; followed by 23000 and 40100 as runner ups. The 1st digit refers to distance value of 1 - 9. The 2nd digit refers to distance value of 10 -19; the 3rd, 20 - 29; and so forth and so on.

The distance mix of 32,000 means: 3 values of 1 - 9; and 2 values of 10 -19. The triple zeroes means no distance value from 20 - 41. As an example is: 5 • 2 • 2 • 17 • 13 corresponding to lotto numbers 4 • 9 • 11 • 13 • 30 • 43 (Sep 20, 2015 result). [9 – 4 = 5; 11 – 9 = 2; 13 – 11 = 2; 30 – 13 = 17; 43 – 30 = 13]

At a different perspective, examine the data just above, Probable Mixes of Distances. This set of data presents which set of distances usually go with what set. You can see that the most common is a mix of 1 - 9 and 10 - 19 (1078 results). You may ask just how many 1 - 9 and how many 10 -19? Just look at the other table Instances of Distances for Every Combination. The possible mixes are: 32000, 41000, and 23000.

You can also mix 3 sets of values such as: 31100 means 3 of 1 - 9, 1 from 10 - 19, and 1 from 20 - 29. For example: 5-2-12-2-23 derived from the winning combination on Jan3, 2016 — 26 • 10 • 5 • 24 • 49 • 12 or arrange numerically, 5 • 10 • 12 • 24 • 26 • 49. Just go ahead, make the subtraction.

Note that the other mixes such as solely 20s and 30s do not really mix.

The Unique vs Duplicate Factors

Based on the history of winning results of Ultra Lotto 6/58, the distances of most winning combinations are unique, making up 55.64% of all results. If two distances are equal, they make 38.31% of all the results. The rest have either 3 or 4; but 4 make only 0.44% of all the results, equivalent to only 6 actual winning combinations. (See the data, Frequency of Duplicate Distances, under the section Proof of Data.)

Is it possible to have equal distances?

What if your numbers are multiples of 3, such as: 03 • 06 • 09 • 12 • 15 • 18? To calculate their distances, they are all 3; the sum of which are: 3 + 3 + 3 + 3 + 3 = 15.

Though the distance value of 3 is good, which is the 3rd most common (with 614 occurrences), does it make your combination more probable? May be not. In fact, there's only 1 combination, out of 1,375 results, the sum of distances is 15. Moreover, no combination that has this form have won yet. To be in the safe zone, limit the duplicates to 1.

Therefore, it is not advisable to play numbers in which all the distances are the same or equal.

So, What Is Ideal?

What is ideal is to form a combination with unique distances. The 8 May 2018 result is an example: 7 • 18 • 19 • 27 • 46 • 53 with distances of 11 • 1 • 8 • 19 • 7.

The probability that a result has unique distances is 55.64%. Therefore, 44.36% would have 2 or more distances of equal value. The result of 1 May 2018 is an example of a result with 2 distances of equal value: 15 • 28 • 39 • 42 • 48 • 51 with distances of 13 • 11 • 3 • 6 • 3.

Three (3) distances of equal value is already very rare. There were only 6 instances when this study was initially made in 2018. In 2025, it has not changed. Having 4 or 5 equal distances is not probable.

How do we decide which distances should we mix?

The answer is above Instance of Distances for Every Combination.

The Sum of All Distances

Determining the difference or distance between two consecutive numbers is just part of a complete delimiting factor. The sum of all distances also play an important role in combining probable numbers.

Take a look at the following data.

Fig 2.62 Sums of Distances

The preceding column chart presents interesting facts about how winning numbers are combined. Let's take a look at where it peaks.

The Peak 42 - 50. Most winning combinations have a distance sum of 42 - 50. This make 42.53% of all winning combinations. If you're seeing lower columns between 42 and 50, these columns will eventually rise to catch up with the frequency of 42 and 50.
2nd Runner Ups 31 - 41 & 51 - 55. On the left side of the peak are the sums of 31 - 41 which make 29.13% of all results; on its right are the sums of 51 - 55 which make 15.37% of all results. Together they make 44.50% of all the results. If the sum of distances of your combination is any between 31 and 41 or 51 and 55 inclusive, your combination is still considered good because it's not all the time that the sum can be between 42 and 50, which are at the peak.
The Lows: 27 - 30 & 56. Each of these values make only less than 2% of all results. Together, they total 7.14%.
The Rares: 10 - 26 & 57. Each of these values make only less than 1% of all results. Together, they total 5.83%.

To illustrate the significance of the sum of distances:

Let's say, the lotto numbers in your combination are 01 • 03 • 06 • 10 • 16 • 17, which are the birthdays of your parents and siblings. If you are going to validate this combination, you calculate the distances such as:

3 minus 1 = 2
6 minus 3 = 3
10 minus 6 = 4
16 minus 10 = 6
17 minus 16 = 1
To add all the distances: 2 + 3 + 4 + 6 + 1 = 16.

Are your numbers good? Based on statistics, the distances are good because probability says that the lower the value of distances, the better. However, the sum of all the distances is only 16. Statistics also says that your numbers are good if the sum of all distances ranges from 27 - 55 to capture 92.43% probability. If you want to take a risk, you can proceed with your chosen numbers. Note, however, based on data, the sum of 16 has a risk factor of 0.22% probability. In fact, out of 1,375 results, there were only 3 winning combinations, the sums of which were 16.

In A Nutshell

So, how do you apply the probability of distances? Observe these rules.

If a distance is over 41, the probability is zero percent (0%).
The smaller the value of a distance, the greater the probability.
Remember that the difference between the smallest and largest number of your combination should be between 10 and 57 inclusive. This is the same as the sum of all distances.
Using a distance of 1 - 9 has 100% probability. It means that every result that was tested had at least 1 distance whose value is between 1 and 9. The threshold is actually 1 - 8. If you go lower than 8, it will cover only 1369 results instead of 1375; or 99.5% instead of 100%.
The most common instances of having distances between 1 and 9 is 2 to 4. This means that 2, 3 or 4 distances in your combination should rather be between 1 and 9 inclusive.
If 3 - 4 distances are between 1 and 19, the others would definitely be greater than 9 such as between 10 and 30.
You can mix sets of distances such as: 1 - 9 with 10s or 20s or both; but rarely with 30s and 40s.

Algorithm for Programmers

Algo 08. Each time you input a new winning result, arranged the numbers numerically, smallest to largest; then calculate the differences (labeled as distances) between each two consecutive numbers. Update a separate table [tbl_distances] where distances are stored.
Algo 09. When generating a combination of lotto numbers, ensure that the numbers conforms with the rules of distances. The rules of distances are produced based on the data in [tbl_distances].
Algo 10.To populate initially the [tbl_distances], run a program that calculates the distances of every winning combination in the results database updating[tbl_distances] each time a record is processed. Set the rules of distances.

For Spreadsheet Users

Table of Distances

Create a separate sheet labeled Distance.
Create a table with 5 columns —AB, BC, CD, DE, EF—which will contain the values of distances. Populate the table with data by using the MAP function. Input this formula on the very first cell under AB.

=MAP( Results!$B3:$B, Results!$C3:$C, Results!$D3:$D, Results!$E3:$E, Results!$F3:$F, Results!$G3:$G, LAMBDA( a,b,c,d,e,f, SMALL( {a,b,c,d,e,f}, 2)-SMALL( {a,b,c,d,e,f}, 1)))

Copy the same formula to the very first cell in the next column, which is BC. Then change the parameters (in red) in SMALL to 3 and 2 respectively. Do the same thing with the other columns.
Add 5 more columns to count the instances of values. Name them as: 0, 1, 2, 3, 4 to count values that are 1 - 9, the 10s, 20s, 30s and 40s. The formula is as simple as: COUNTIF( A3:E3, "<10") to count the 1s-9s. For the 10s, 20s and 30s, use COUNTIFS.
Add another column to join the values you calculated in #3. Use this formula: JOIN( "", H3:L3) assuming your values are in H3:L3. Label this column Mix of Distances.

Table of Combined Distances

Create another table similar to Instance of Distances for Every Combination. You will find an image of this in this chapter. This is where you will summarize the Mix of Distances using the FILTER function.
Filter the results in Mix of Distances with this formula: =SORT( UNIQUE( FILTER( M3:M, M3:M <> "")), 1, TRUE) assuming your data are in M3:M.
Add another column to calculate the frequency of each distance mix by using a simple COUNTIF function.

These are all you need to monitor the probability of distances.

Manual Method

To calculate the distances of your combination, the manual method simply follows simple subtraction, which you can do it mentally or with an aid of a calculator. Then just be guided with the data you have seen here.

Probability Based on Time

The right time to win and the time to rest

Have you ever wondered when could a lottery number win again? Is there a right time? Based on data, statistics can give you an idea. However, if you apply what data can deliver, it is a hit or miss. Sad to say, it cannot be absolute. Nevertheless, it is a good alternative from just random guess. Would you be excited to find out when a lotto number could probably win again? Statistics can calculate that. All is needed is to count the days or draws between each lotto number's time of winning.

Based on observation, not at all times that a lottery number can keep on winning. There were times when a lotto number do not win for a long period of time. It hibernates. Could there be a signal when a lotto number could probably hibernate? You are about to find out!

Highlights

Trending numbers are those that repeatedly win within a period of 6 draws. Almost half (48%) of the winning numbers were trending numbers. There's an 81% chance that 2 – 4 of the winning numbers are from the last 6 draws. Some people call these hot numbers.
Neutral numbers are those that have not been winning for the last 7 – 13 draws. 27% of the winning numbers are called neutral numbers. There's an 83% chance that 1 – 3 of the winning combination are neutral numbers.
Generally, cold numbers are those that have not been winning lately. Some call them skippers; idle or inactive lately. Skippers for a long time, such as those inactive for the last 14 draws or more, have the tendency to win again. The odds for them to win again is 18% – 35%.

The Study Of Time

The probability of time answers the questions: How long does it take for a lotto number to win again?

Scope and Methodology

1,378 draw results from PCSO's Ultra Lotto 6/58 collected and studied, covering the draws 8 February 2015 up to 19 August 2025. For each lottery number, the number of draws between two consecutive occurrence of the same number were counted. It excluded the very first twelve draws for the reason that during this period, only 29 yet of the winning numbers had won more than once. To give you an idea of the calculated results, on 10 Aug 2025, #15 won. Three draws had passed, no win for #15; but on the 4th draw after its last win, #15 won again. Therefore, the calculated count for #15 during that time was 4. Say, 4 is the common calculated value for #15, you can theorize that most of the time, #15 wins every 4th draw. This is just an example. You would see the data in a little while.

To keep it simple, the calculated count of draws between two occurrences of the same lotto number is labeled as TimeAge or simply Age. A similar term is Skips. So, TimeAge, in this report, would be defined as any and all of the following:

In general sense, it is the amount of time between two events of winning. Time can be the number of days, or the number of draws.
Elapsed draws, ie the number of draws that have passed without a lotto number winning. In other words: how long a lotto number has not been winning. A similar term is called skips.
The elapsed time or elapsed number of draws since the last win of the lotto number up to the current date. For example, if today is Friday and the last win was on Monday, you count from Tuesday to Friday which is 4, ie 3 elapsed days plus the current day. In the case of Ultra Lotto, time is counted as number of draws.
Age is also the period that a lotto number is at rest or hibernating; i.e. has not been winning.
Strictly speaking, timeage is equivalent to elapsed draws plus 1, ie to include the time of winning.

To give you a better information about the Age data, the values were tallied, summarised and interpreted.

Presenting the Data of Time: Age

To give you an idea what the Age values look like, find it on this screenshot of the spreadsheet where I calculated the data. On its left are the actual results of Ultra Lotto 6/58. On its right are the calculated ages (number of draws that have passed without winning) of each lotto number.

What the Ages Reveal

Here's a screenshot of my data that summarizes all the calculated age values (see prior screenshot).

Age refers to the number of draws that have passed prior to the next win of the same lotto number. On record, age values range from 1 to 98. The image is showing only up to 39 because the whole thing cannot be captured on the whole screen. If Age is 1, it means that the lotto number won twice consecutively (a repeater), ie zero skips (or elapsed draws) +1.
Occurrence refers to the number of times an age value has occurred.
% is the probability percentage; i.e. the number of occurrences over all instances.
Accum % is the running sum of percentages. This is to establish up to how many draws is, at least, 90% significant.
In Results refers to the occurrence in terms of numbers of draws, rather than individually as a number.

How to Read the Table of Ages

Age 1 has 857 occurrences. This means that there were 857 instances when some lotto numbers won again immediately in the next draw. This is what some call it a repeater. Out of 1,378 results, 683 of them produced, at least, 1 repeater.

Age 2 has 754 occurrences. This means that there were 754 instances when some lotto numbers did not win immediately in the next draw but it won after the next. In other words, it took only 2 draws for the same number to win again. Some call this number a leaper, which means it skips one draw, then it wins again in the next. Of all the results, 627 of them consisted of, at least, 1 leaper.

Age 3 means 3 draws after the lotto number's previous win; 4 means 4 draws after winning; and so forth and so on.

Age 1 to age 6 comprises 48% of all instances. This means that there's a 48% probability that a lotto number may win again within 6 draws. At 72%, a lotto number may win again within 12 draws; and at 82%, within 16 draws. Overall, all lotto numbers may win again within 30 draws. Beyond 30 draws is already rare which is at 3% probability. If you prefer at 100%, ultra lotto numbers can win again within 45 draws. Beyond that is already exceptional and very rare.

Notice that the sets of ages are grouped and colour coded. That is explained next.

The Colour Zones

The purpose of the colour zones is to establish the period, based on age range, as to where the winning numbers usually come from more frequently. Based on the just preceded probability data, the following findings reveal that:

Trend zone. The trend zone, also called trending period, is statistically established as the significant period for the reason that 90% of all winning numbers studied come from this 21-draw period. It covers ages 1 to 21 or simply the 21 consecutive most recent draws.
The trend zone is divided into two: the active and the passive zones. The active zone comprises the upper 13 draws (purple and green zones); while the passive zone comprises the lower 8 draws (orange and aqua zones). The active zone is the period where numbers tend to win again and again, or remain trending (75% probability); while the passive zone is where the numbers may turn cold or cease to trend (14.91% probability of winning); or jump up to trend again.
Purple zone. The purple zone is also called the hot zone for the reason that almost 50% (exactly 48.24%) of all winning numbers come from the hot zone. This also tells us that the other half of the winning numbers come from the lower zones. The purple zone covers the 6 most recent draws; or ages 1 - 6.
Green zone. The green zone is the area where the other winning numbers (27.08%) come from. So, if you are going to pick 4 numbers from the purple zone, pick 2 from the green zone. The green zone covers ages 7-13. In other words, pick 4 numbers whose ages are any from 1 – 6; and 2 numbers whose ages are any from 7 – 13.
Orange zone. 8.97% of the winning numbers come from the orange zone. You can pick 1 number from this area. The purple, green and orange zones together make up the 84% of the winning numbers. The orange zone covers ages 14-17. This is the area where lotto numbers seem to stand at crossroads: whether it proceeds to turn cold, or jump up to trending positions.
Aqua and blue zones. The aqua and blue zones make up the cold zone. Once a number reaches the aqua zone, that number likely ceases to trend. The aqua zone makes up 5.95% of the winning numbers; the blue zone, 6.74%. Together, they make up 12.69% of the winning numbers. At rare times, one winning number can possibly come from the cold zone. The aqua zone covers ages 18-21; the blue zone, ages 22-31. Once a cold number has left the aqua zone and has entered the blue zone, there's a big chance for this cold number to hibernate.
Grey zone. The grey zone is referred to as the hibernation period. This covers the age period 32 to 98. Dormant numbers cannot hibernate forever. At one point, it is going to win. It is just a matter of time, but when? Numbers in hibernation have only 3.16% chance of winning again.

Following is the rest of the data showing the probability of less than 0.5% (collectively at 3.16%) of lotto numbers to win again while hibernating. So, if your favourite number is in hibernation, it is a good advice to set it aside for the meantime. Up to when? The data can suggest when; but more on that soon.

Combining Numbers Based On Colour Zones (Standard 07)

Now that you know that almost 50% of the winning numbers usually come from the last 6 draws (purple zone) and the rest come from the other zones, how many numbers from the purple zone should you combine with those from the outside zones?

Presenting the data: The instance of age values in winning combinations

Combining lotto numbers based on age values

Combining Your Numbers Based On the Instance of Age Values

Instance: There are 6 numbers in a combination; therefore, there can only be 6 possible age instances in a combination plus its non-existence. Instances are 1 - 6 which refers to the existence of the age value in a winning combination. The absence of which is zero. It answers the question: Is it possible that all winning numbers can come from only the purple zone; is it a mix of two or three zones? Look an instance value 6. On record, there were only 10 winning combinations whose numbers came from the last 6 draws, or the purple zone.
Column labels 1-6 through 32+: These labels refer to the ages of lotto numbers prior to their next win. They are grouped into colour zones: purple, green, orange, aqua, blue, grey. (Read previous discussion regarding the nature of Ages.) The values under these columns refer to the frequency of instance in all of the winning combinations. For example, of all the winning combinations, 472 of them consisted of 3 numbers that came from the purple zone. If a number is said to have come from the purple zone, it means that it had won in the last 6 draws; or in other words, its last win was during the last 6 draws.
Percentages: The lower portion contains the calculated percentages of the figures above it; i.e. frequency of instance over all draw results.

Illustration of Ageing, Zoning and Selecting a Number By Zone

To give you a clearer understanding of what is being discussed here, following is an illustration of how ages are calculated; how the colour zones are determined; and which numbers refer to which colour.

Assumption. Assume that today is 18 Aug, the current date, which means that the 19 Aug has not happened yet. So, the latest draw is 17 Aug. At this point, you have no idea which numbers would win on 19 Aug.
Determining the colour zones.

Starting from the current draw, 17 Aug, count 6 draws. That's the purple zone or hot zone—17 Aug to 5 Aug— where half of the winning numbers usually come from based on probability.
Then count 7. That is the green zone—3 Aug to 20 July. One or two numbers would come from the green zone; sometimes 3 but rarely.
Then count 4 to mark the orange zone. This is the crossroads zone where numbers would either trend again, or become cold.
Count another 4 to mark the aqua zone. This is the start of the cold zone. There is a 26% chance that one winning number would come from this zone.
Finally, count 10 draws to mark the blue zone. When a number enters the blue zone, it signals its hibernation.
The rest becomes the grey zone.

Which numbers belong to which colour zone?

The numbers you see in bold font are the numbers that belong to that colour zone. The rest in light grey means that they do not belong to that zone where you see them. How is this determined? You look at the number's latest win. Take note that, we are illustrating that Aug 19 draw has not happened yet; thus, we are not counting it.
For example, #10 won on Aug 1. It has not won for the last 7 draws; thus, it is the green zone. So, this is #10's latest win. If it wins in the next draw (Aug 19), it goes back to the purple zone (age 1). If it does not, it continues to be in the green zone. If it continues not to win, soon it will be in the orange zone.
Now look at #07 (age 8, 1 Aug). It is in grey because it does not belong to the green zone; #07's latest win was on 15 Aug. So, currently, #07 is in the purple zone.

How to calculate the age of a lotto number?

All the numbers of Aug 17 are age 1 because they are the current winners.
All the numbers of Aug 15 are age 2 because they did not win on Aug 17. If one of them won on Aug 17, its age will be 1, not 2.
Look at #21 of Aug 5 (age 6). Counting from the current draw (Aug 17) until Aug 5, that is 6 draws. So, the age status of #21 is 6.
Try this. What is the age status of #15? Remember our assumption that today is Aug 18. What is your answer. Count from Aug 17.
Try #57 which you see on Aug 17, Aug 12, Aug 10 and July 13. Count its age at the time of its win. Try counting from down-up and from up-down. Check your answer on the right.

Selecting numbers from the colour zones. Say, the probability rule is to pick 3 numbers from the purple zone, 2 numbers from the green zone, and 1 number from the orange zone. What are your choices?

Remember that you can only pick those in bold numbers. The numbers in light grey do not belong to the zone where you see them.
Let's add another rule just for fun. Do not pick 2 numbers from the same row. Pick 2 numbers from the same column while the rest of the 4 numbers should not belong to the same column.

Analysis of the Colour Zone Data

Here's what the data of the colour zones reveal.

Purple or Hot numbers. Imagine the 6 most recent winning combinations of Ultra Lotto. There are 36 numbers all in all. Some of these numbers have won twice or thrice within that short period. Most likely, based on probability data, 2 - 4 of these numbers may win again in the next coming draw. The chance for that to happen is 81%. There's also a 10% chance that only 1 of these numbers can again win in the next draw. Is it possible that the 6 winning numbers can all come from this period. Yes, but the chance for that to happen is only 0.7%. Is it also possible that no winning numbers could come from this period? Yes, that already happened; however the chance for that to happen is only 1.5%. So, when combining your numbers, consider choosing 2 - 4 numbers that had won during the last 6 draws.
Green or underdog numbers. If 2 - 4 winning numbers can possibly come from the last 6 draws (or purple zone), where do the others come from. Based on data, 1 - 3 of the winning numbers can also come from the green zone; i.e. from the last 7 - 13 draws. The probability for this to happen is 86.9%.
Orange or crossroads numbers. One number from the orange zone can also possibly win again. The chance of its winning is 35%.
Cold numbers from the aqua and blue zones. Yes, a cold number will eventually again. Should a winning number come from this period, pick only one. Both of these zones deliver less than 30% chance of winning again.

Setting The Standards and Delimiters

Guide To Choosing Your Numbers

As a guide to choosing which numbers to play, consider the following:

2 - 4 numbers from the purple zone usually win again. Having 1, 5, 6 or none is rare.
1 - 3 numbers from the green zone can possibly win again. All other possibilities are rare.
1 - 2 numbers from the orange zone can also possibly win. All other options are very rare.
The cold zone can produce 1 winning number, each from the aqua and blue zones.
If you want to be adventurous, you can pick one hibernating number.

To summarise.

Zone	Numbers to Play	Rare Case	Least Probable	Almost Improbable
Purple	2 - 4	1 or 5	None	6
Green	1 or 2	3 or none	4	5, 6
Orange	None or 1	2	—	3, 4, 5, 6
Cyan	None or 1	2	—	3, 4, 5, 6
Blue	None or 1	2	—	3, 4, 5, 6
Grey	None or 1	—	2	3, 4, 5, 6

There's another rule that you have to observe when picking numbers from the different zones. That is, always pick the number from its latest win. For example, say #12 won on the 6th, 12th, and 24th draw (i.e. age 6, 12, 24), pick #12 on the 6th because #12 is now part of the purple zone. It is no longer a number from the green zone (12th) nor from the blue zone (24th). So, if you are going to pick a number from the green zone, make sure that this number does not exist in the purple zone. Likewise, if you are going to pick a number from the blue zone, make sure that this number does not exist in the other zones above it. This was illustrated previously (Illustration of Ageing, Zoning and Selecting a Number by Zone).

Occurrences of Age Sequences

The next question is: How do you combine numbers based on the probability zones? For example, should you combine purple numbers with green numbers; or purple numbers with orange numbers?

There are 462 possible combinations of age sequences. On record, only 153 exists. Forty-one of them have occurred only once; while the rest have occurred twice up to 88 times. Age sequence 420000 is the most common with 88 occurrences.

The purpose of determining the age sequences is to find out if there are certain sequences that are more common.

How the Age Sequences are Formed

The following screenshot presents how the age sequences are formed.

Fig 2.71 Age Sequences Data

For each combination, all age values that fall in the same colour zone are counted. For example, the calculated ages of the winning numbers from of 19 Aug – 15 • 43 • 7 • 40 • 52 • 29 – are 4 - 5 - 2 - 10 - 5 - 16. There are 4 values that are less than 7 (purple zone), 1 from the green zone, and 1 from the orange zone. Thus, the age sequence is 411000 where:

The 1st digit 4 refers to numbers in the purple zone;
The 2nd digit 1 refers to the number in the green zone;
The 3rd digit 1 refers to the number in the orange zone;
The 4th digit 0 means no number from the aqua zone had won;
The 5th digit 0 means no number from the blue zone had also won;
The 6th digit 0 means none of the hibernating numbers (grey zone) were part of the winning combination.

The significance of these probable age sequences is that it constraints your choices of combining your 6 lotto numbers. For instance, there is no record yet of 000006 age sequence where all winning numbers are all hibernating numbers (age values of 32+). Therefore, you would not risk playing this type of combination.

Following is a list of the most common age value sequences. The highlighted percentages make up 65.69% of all recorded winning combinations.

Most common age sequences lottery 6/58

Sum of Ages as Delimiters

The possible minimum age value is 1. If all ages of a combination are 1, the total of which is 6 making it the minimum sum of all possible ages. On record, the oldest age is 98. Suppose, all the winning numbers were from age 98, then the possible maximum age value is 98 * 6 = 588. But not every sum value is probable. So, which sums are probable? Let's find out.

By calculating the sum of the ages of every winning combination, you will be able to determine what is probable; thus, delimit the numbers you wish to play. The sums of the ages, on record, range from 10 - 150. Sum values which are <19 or >133 have occurred only once. However, there were other sum values which are <133 that also occurred only once. Data seem to be distorted. For that reason, a significant probability could not be established.

For now, let 10 - 150 be the standard delimiters as far as sum of ages is concerned. Meaning, if you add all the values of ages of a lotto combination, the sum should not be less than 10 and greater than 150.

In A Nutshell

Trend zone (most recent 21 draws). 90% of all winning numbers come from the trend zone. The other 10% are numbers that have not won from the last 21 draws or greater.
Purple zone. It is called the hot zone because 2 - 4 of winning numbers are usually those that have won previously from the most recent 6 draws.
Green zone. The green zone is not as hot as the purple zone; but from time to time, 1 - 3 of the winning numbers would come from the green zone. These are numbers that have not been winning from the last 6 draws.
If there are numbers that have not been winning from the last 13 draws, most probably one of them would win again.
A cold or hibernating number would eventually win again. It is just a matter of time.

Try This Exercise

List the winning numbers from the 6 most recent draws (purple zone). Highlight those that have won twice. Pick 1 or 2 numbers from these. Using another colour or mark, highlight those that have won once. Pick 1 or 2 numbers from these.
List the 7 next winning numbers prior to the 6th draw (green zone). Disregard all the numbers that have won from the most recent 6 draws. From the remaining numbers, pick 1 or 2.
Do the same thing with the other zones (orange, aqua, blue, grey).
At this point, you may have chosen a maximum of 10 numbers. Pick 6 numbers to play. To delimit your choices, pick only one number from a winning combination.

Ch 8

Percentile Ranking of 6/58 Lotto Numbers

Disecting the Top and Bottom Numbers

In Chapter 1, you were introduced to the top and bottom numbers: the top 29 and the bottom 29. To form a combination based on probability, you pick 3 top numbers and 3 bottom numbers. In some cases, you may pick 2 top numbers and 4 bottom numbers; or vice versa. What if, we can be more specific like dividing the top numbers into 10 in such a way we will have the top and bottom 10%s and everything above and below the median?

Highlights

By classifying the lotto numbers into 10 groups based on their frequency of winning, we would be able to identify which numbers are more likely to win compared to others.
The combined ranking of every number in a combination, if transformed into a decile sequence, each decile sequence is unique.

The Decile Groups Probability

To narrow down our choices, instead of selecting only from the top 29 and bottom 29, what if we can also identify the middle numbers? The middle numbers would comprise of those above the median and below the median. In such case, I decided to classify the numbers into 6 so that for each 1/6th group, we narrow down our choices to only 9 numbers instead of 29. This is what I did in the late 2017. The result of that 2017 study is discussed towards the end of this chapter.

With the desire to really capture how random numbers win, I decided to break down further the top, middle and bottom numbers. Instead of just 6 groups, I grouped the winning numbers into 10. To identify which number goes to which group, I ranked each number based on its frequency of winning.

The 10 groups would be classified as follows, where the higher the percentage, the greater the frequency:

90% - 99%
80% - 89%
70% - 79%
60% - 69%
50% - 59%
40% - 49%
30% - 39%
20% - 29%
10% - 19%
1% - 9%

You might have noticed why there are no 0% and 100%. There are no zeroes because every possibility already exists. Then, instead of using 100%, I decided 99.99% to be the highest rating.

This study covers 1,383 actual results from the PCSO Ultra Lotto 6/58. It covers data from the very first draw, 8 Feb 2015, up to 26 Aug 2025. However, to establish a more coherent data, I did not include the first 30 draws for the reason that not all of the 58 numbers had won yet during that early period. One particular number, #28, had not won yet during that period. It hit its first win only on the 31st draw.

Comparative results of the winning numbers's ranks 2015-2025

Observation

The 2015 ranking consisted of only 90 draws. Based on the results, it seemed to suggest that if a number ranks 1 to 29, it is more likely to win. But that trend then changed towards the end of 2017 when it already covered 339 results.
Based on the 2017 results, it showed that most winning numbers were ranked 10 – 39. However, that changed again by 2019.
Towards the end of 2019, which sampled 648 draw results, numbers that mostly won are those that ranked 10 – 29, 40 – 49 and 60 – 69.
By the end of 2021, when sampled data covered 902 results, numbers that ranked 80 – 89 were likely to win as well aside from those mentioned in 2019.
Since 2021 up to 2025, when sampled data already covered 1383 drawing results, the standing of the numbers's ranking remained consistent. Most likely, this standing will not change in the many years to come (Law of Large Numbers). For that reason, we can already set the results as standard.
Numbers that ranked higher such as 90 – 99 were consistent to be not often the winners despite their high ranking.
Numbers that were consistently low ranking, therefore, not very often the winners, were those that ranked: 30 – 39, 50 – 59 and 70 – 79.

Ranking Standard

Numbers that mostly win are those that are ranked:
10 – 29, 40 – 49, 60 – 69, 80 – 89.
If numbers are ranked 90 – 99, there is a low probability that they might win again. Wait until they rank lower in order for them to win again. That probability, however, is not that much low.
Other rankings have slightly low probability because of its nature of variability. For example, very seldom that numbers rank 70 – 79 because most of the time they rank either 60 – 69 or 80 – 89. In other words, not all ranks exist all at the same time after every draw because the rate of frequency of each number are very close. Nevertheless, these low probability rates are not absolute. It means, regardless of their slightly low probability, their chance of winning is still possible.

Fig 2.81 RANKING OF 6/58 LOTTO NUMBERS BASED ON FREQUENCY OF WINNING

The above chart presents how the lotto numbers of Ultra Lotto rank according to their frequency of winning. This is based on data in 2025. If the database has been updated, you would see the more current results. Use these data to select the numbers you wish to play following the standards just discussed. You may refer to the table of ranking column 2025.

We will revisit this ranking probability when we discuss about Trends in Part 3. In that chapter, the ranking of the lotto numbers for a shorter period become more significant.

Summing The Ranks

With the calculated sum of the ranks per combination, no significant probability was established for the reason that there are so many possibilities—245 all in all. Any sum could occur once or up to 20 times. The values of the sums are spread without order. For that reason, it is like there were no low point or high points; nor were there consecutive values peak to a hill. What only remains is that, for now, the possible combined sums range from 91 – 484.

Probable Group of Ranks

Here is the question: If 10 – 19 is the most common probable rank, which ranks usually go with it to form a winning combination? To find out is to determine each winning combination's sequences. To give you an idea what the data look like, following is a screenshot of said data.

SAMPLE HOW NUMBERS ARE RANKED AND GROUPED

How the Ranking is Done

The first set of data are the actual lottery results of Ultra Lotto 6/58.
Corresponding to it is the second set of data that calculates the winning frequency of each lotto number prior to the current draw. It does not include the current draw because we are after the numbers's standing before winning again. For example, #31 had won 128 times before winning again on 26 Aug.
Corresponding to each frequency value is the equivalent rank of each lotto number, shown by the 4th set of data. Ranks are in percentage 1% - 99% where 99% is the highest rank equivalent to the highest frequency value.
The 3rd set is the decile classification of the lotto numbers. Decile classification is 0 – 9 where 0 refers to ranks 1% – 9%; class 1 refers to ranks 10% – 19%; class 2 refers to ranks 20% – 29%; and so forth and so on. Notice that the decile classification simply gets the first digit of the ranks. For example, rank 37 is classified as decile group 3. If rank is less than 10, decile classification is 0.
Pay attention to the decile classification. It tells us how the combined numbers are ranked as a group. For example, the 26 Aug winning numbers were ranked as follows: 033574. This tells us that:

#31 ranked less than 10%, or 5% to be exact.
Two numbers, #04 and #36 ranked 37% and 32% respectively, which both fall under the class 3.
#35 belongs to the class 5 because its rank is 53%.
#16 falls under class 7 for ranking 73%;
#50 falls under class 4 for ranking 46%.

The Significance of the Decile Sequences

Let's follow our given example decile sequence 033574. Suppose this sequence is very common, then you would have an idea which set of numbers are more likely to win. You simply look for numbers that rank 1% – 9%, 30% – 39%, etc. However, decile sequences are not repeated; it is like saying that they do not win twice. From another perspective, you can come up with an idea that, say, if numbers rank as 0, 3 or 4 (this is just an example), they usually go together; or, most sequences consist of unique numbers; or, it is not probable that 5 lotto numbers would have the same ranking such as this sequence: 000006.

What the Data Reveal

Here is a very interesting finding about rank sequences—all rank sequences are unique; there are no duplicate sequences. For example, rank sequence 033574 is the only sequence that exists in the data. The same is true for every rank sequence in the database. So, say the numbers that you are about to play produce the same rank sequence 033574, most likely, based on probability, it might not win because it already exists. Your numbers have better chances if its rank sequence does not exist yet.

To this date (Aug 2025), Ultra Lotto has produced 1383 possible combinations. There are more than 40 million possible combinations. Therefore, it will take more than 200,000 years before we see some duplicates or multiple occurrences of exactly the same sequence.

Occurrences of Each Rank Group in Every Combination

The next thing to find out is: Which of the numbers in a combination usually win at which rank?

OCCURRENCES OF EACH RANK GROUP IN EVERY COMBINATION

What the Data Reveal

As mentioned earlier, each winning number was classified based on its frequency ranking. The ranks were grouped from 0 to 9 where 0 refers to rank 1% – 9%; 1 refers to rank 10% – 19%; rank group 2 refers to rank 20% – 29%; and so forth and so on. You can see those rank groups on the data just preceded. Under each rank group are the number of occurrences in our sample data. The probability of each rank to exist ranges from 38% – 54%. Not much deviation, though noticeably, numbers that ranked 90% – 99% had lower probability compared to others.

Exploring further, the frequency of the ranks existence were broken down to 1 – 6 where 1 means a single instance in a combination; 2 means two numbers in the combination ranked in the same group; 3 means 3 numbers ranked in the same group; and so forth and so on.

Note that 5 and 6 had zero existences. That means that it is not probable for 5 to 6 numbers in a combination to win if all of them fall under the same rank group. For example, say, 5 • 10 • 15 • 20 • 25 • 35 ranked as follows: 70% 75% 72% 73% 79% 74%. Per rank group, its equivalent is 777777. Based on data, this form of combination is very unlikely; thus, unlikely to win. Therefore;

If 5 or 6 of the numbers in a combination all ranked under the same rank group, that combination is unlikely to win.
If 4 of the numbers in a combination all ranked under the same rank group, there's a extremely low chance for that combination to win. On record, that type of combination happened only once, twice, and thrice; or not at all.
Therefore further, a probable winning combination can only contain 1 or 2 numbers that belong to the same rank group. For example, 033574 of Aug 26 (see previous data) where each number fall under different rank group except for #04 and #36 which both fall under rank group 3. Another example is the Aug 10 result, the combined rank groups of which is 739406 where each number comes from different rank groups.

Occurrences of Unique and Multiple Ranks in a Combination

Based on the data just discussed, each rank group has almost equal share in winning—generally at 45% – 54% probability; except for the rank group 9 which has a lower probability of 38%. In every combination, it is common that each rank group exists only once. There are cases that it may exist twice. Exploring further, the second set of data reveal something more detailed.

Double — At 46% probability, two numbers belonged to the same rank. For example, 033574 where two numbers both ranked 3.
Double Double — At 22% probability, two numbers belonged to the same rank; and another two belonged to another same rank. For example, 388132 (15 Aug 25 result) where two numbers belonged to rank group 3; and another two belonged to rank group 8.
Unique — At 17% probability, all the six numbers in a combination belonged to different rank groups. For example, 739406 (10 Aug 25 result) where none of the numbers belonged to the same rank group.
Triple — Less common at only 9% probability, where three numbers belong to the same rank group. For example, 867727 (17 Jun 25 result) where 3 lotto numbers all belonged to rank group 7.
Triple + Double — At only 4% probability where two numbers belonged to the same rank group; and 3 numbers belonged to the same rank group. For example, 452454 (4 Apr 25 result).
The rest of the possibilities have only either 1% or 0% probability.
- Triple Doubles— At almost improbable rate of 1%, this is where 3 sets of 2 numbers each belong to the same rank group. For example, 517571 (20 Apr 25 result).
- Quad — Also at 1% probability, this is where 4 numbers belong to the same rank group. For example, 666624 (12 Sep 23 result) which happened only once.
- Quad + Double — Also at 1% probability and existed only once, this is where 4 numbers belonged to the same rank group; while the other 2 belonged to another group. For example, 181181 (8 Apr 25 result).
- Quint and Hex — At 0% probability, this has never happened yet. This is where all the 5 or 6 numbers in a combination belong to only one rank group.

The Late 2017 Study

Let me share the study I did in late 2017. In this early study, the data were divided into 6 groups. Each hextile comprises one-sixth (1/6) or 16.67% of the data. If divided equally, each group comprises 9 or 10 lotto numbers. However, in this study, the lotto numbers were grouped, then ranked, based on the number of times each number had won. For that reason, a hextile or one-sixth group may include a variable number of lotto numbers ranging from 6 to 15 lotto numbers depending on each number's performance.

Group 1 (H1) comprises the top 1/6 (16.67%)
Group 2 (H2) comprises the 2nd top 1/6. Together with group 1, they make the top ⅓.
Group 3 (H3) comprises the middle 1/6 above the median. Together with groups 1 and 2, they make the top 50%.
Group 4 (H4) comprises the middle 1/6 below the median. Together with groups 5 and 6, they make the bottom 50%.
Group 5 (H5) comprises the upper bottom 1/6. Together with group 6, they make the bottom ⅓.
Group 6 (H6) comprises the bottom 1/6.

The study covered only 323 results of Ultra Lotto. For that reason, trends were very obvious; but not enough to make the probability findings a standard.

Top One-Sixth (H1)

Based on 323 results, the following are the top 16.67% winning numbers of Ultra Lotto system 6/58.

06 • 13 • 54 • 08 • 38 • 58 • 34

These numbers have won 289 times out of 1938 balls – a probability of 15.72%. Collectively and individually, they had won from 217 results out of 323 drawings - a probability of 67.2%. However, only 11 draws resulted to three winning numbers; and only 1 draw gave four winning numbers. This means that the other 206 results were no-prize winning results giving only 1 or 2 winning numbers.

Perhaps, you’re wondering why the top winning numbers are not exactly sure winners?

The answer is randomness. The balls have no fixed positions. The moment you touch one ball, the rest of the balls move. That’s the concept of randomness. For that reason, we can quickly come up with a conclusion ~

The winning balls are unpredictable.

If such is the case, is there a way to be, at least, closer? There’s only one way to find out and that’s with the use of probability.

The Top Thirds (1/3) Winning Numbers (H1 + H2)

The following are the next top winning numbers, making them, together with the top 16.67%, the Top One-Third (33.33%). These numbers belong to Group H2.

22 • 02 • 25 • 33 • 39 • 10 • 41 • 46 • 14

The Top 1/3 winning numbers make the 33.33% of all winning balls - a total of 635 balls equivalent to 303 draws out of 323 drawings, or 93.8%; 91 of those are prized winners having 3 to 5 winning numbers. Four draws produced five winning numbers; 19 draws produced 4 winning numbers.

Therefore, playing the Top 1/3 numbers gives you 28.17% probability of winning 3 to 4 numbers; but not 5 or 6 numbers. However, if the Top 1/3 consists of 16 lotto numbers, you need to play 8008 combinations in order to ensure your winning ⎯ not practical to play them all. Perhaps, there is a better way to play 16 numbers with a few combinations.

Moreover, if only 1 to 4 of the Top 16 numbers can possibly win from 93.8% of the draws, which other numbers are winning?

The Top 50% (H1 + H2 + H3)

So how many numbers should you play to raise your chances of winning to greater than 50%? Let’s add the remaining top numbers to complete the Top 50%. These numbers belong to the H3 group or the middle top 16.67% above the median.

23 • 27 • 29 • 11 • 40 • 56 • 15

Playing the Top 50% gives you 99.07% probability of your numbers making it to the results. Of this rate, 77.4% probability is attributed to winning prized money; i.e. winning 3 to 6 numbers. Here's the complete stats.

36.53% chance of winning 3 numbers
26.93% chance of winning 4 numbers
12.38% chance of winning 5 numbers
1.55% chance of winning 6 numbers (or jackpot)
18.89% chance of winning 2 numbers
2.79% chance of winning 1 number
0.93% chance of winning 0 number

Though there is a great probability that the Top 50% can give you the winning numbers, the chance of winning the jackpot is only 1.55%. If such is the case, it only means that the other winning numbers would be coming from the bottom 50% numbers.

The All-Time Bottom Numbers

The other 50% of the numbers belong to the bottom group, comprising the 3 bottom hextiles.

The middle 16.67% bottom below the median (H4)
The upper 16.67% bottom (H5). Together with H6, H5 + H6 comprise the bottom thirds (1/3).
The lowest 16.67% bottom (H6)

The Middle Bottom (H4)

This is the first set of the bottom numbers below the median.

23 • 27 • 29 • 11 • 40 • 56 • 15

What is significant in this group is that it is very unlikely that 3 to 6 winning numbers could come from this group. So, if you find 3 to 6 numbers of yours in this group, most likely they are not going to win because the probability of 3 to 6 winning numbers to come from this group is only 2.2%. However, there is an almost 50%:50% chance that no or 1 winning number can come from this group.

The Bottom Third (H5 & H6)

Below are the numbers that belong to the bottom ⅓.

Bottom H5

44 • 19 • 17 • 52 • 57 • 20 • 07 • 21 • 30 • 32 • 48 • 26 • 31

Bottom H6

35 • 49 • 05 • 18 • 45 • 42 • 24 • 55 • 28 • 37

Comparative Stats of the Bottom Numbers

Winning Numbers	H4%	H5%	H6%
0	46.1	24.5	45.8
1	36.8	38.7	37.5
2	14.9	27.9	14.2
3	1.9	6.8	2.2
4	0.3	1.9	0.3
5	0	0.3	0
6	0	0	0

Observations

It is more probable that no winning number could come from group H4 or H6
There is almost a 50:50 chance that one or no winning number could come from group H4 or H6
It is more probable that 2 winning numbers could come from group H5 rather than from groups H4 or H6
It is almost definite that no 3 to 6 numbers can come from groups H4, H5 or H6.
38% of the results comprised 3 top winning numbers and 3 bottom numbers.
There’s only 0.6% when a result comprised all bottom numbers. So, forget playing all bottom numbers.
Likewise, there’s only a 1% chance that a result contains all top numbers.
Therefore, your combination should comprise, at most, 3 top numbers and 3 bottom numbers. In some cases, you can play around the ratio 2:4, which means 2 top numbers and 4 bottom numbers or vice-versa.
Top winning numbers do not win all together. They share the spot with bottom numbers.
You have a slimmer chance if you pick your numbers only from the top 27. The top 27 lotto numbers comprise the top winning 50%.
The odds of winning increases if you include a few bottom numbers, starting with the middle 9.
Without the middle 9, there are greater chances to win 3 numbers.
With the middle 9 considered, the chance to win 4 numbers increases. Draw results usually comprise 4 top winning numbers and 2 bottom numbers.
Pick 4 numbers from the top 27. The middle 9 numbers are enough to be the source of the 2 bottom numbers.

In A Nutshell

The all-time winning frequency of each lotto number was calculated; and based on this frequency, the numbers were ranked from 1% to 99% where 99% is the highest rank. After every draw, this ranking was calculated to determine the status of each number as far as ranking is concerned.
Based on rankings, there were lotto numbers that were likely to win more if its ranking is greater than 9% but less than 30%. Revisit the table presented earlier in this chapter.
Each winning combination was transformed into a rank sequence. If a number's rank is between 1 and 9 inclusive, it is classified as rank group 0; if it is between 10 and 19 inclusive, it is classified as 1; if between 20 and 29, it is classified as 2; and so on and so forth. This grouping reveals a rank sequence for every winning combination. Surprisingly, each rank sequence combination is unique. It is like you can say that jackpot numbers do not win twice. Likewise, the rank group patten of each combination do not also win twice.
As for rank group combination, the most common are: double, unique, and two doubles. Double—2 numbers belong to the same rank; two doubles—4 numbers belong to two the same ranks; unique—all numbers come from different ranks.

Manual and Spreadsheet Application

It is not easy to apply these rank standards and delimiters manually. You will need a spreadsheet application to calculate each rank of winning numbers. Soon, I will share the spreadsheet that I have prepared for this. In the meantime, you can view the current ranking of each number on this chapter, or at the beginning of Part II.

The Probability of Number Diversity

Numbers of A Feather Do Not Flock Together

Perhaps you have noticed that most of the time, the winning numbers come from different houses. Very seldom you see, or even not at all, winning numbers such as this: 24 29 22 20 23 26 where all numbers belong to the house of 20s. Why is that? Let us look at the statistics.

Which Numbers Belong To Which House

In this study, we grouped the lottery numbers into 6 based on their first digit. Thus,

House of 00s comprises the lotto numbers 01-09
House of 10s, lotto numbers 10-19
House of 20s, lotto numbers 20-29
House of 30s, lotto numbers 30-39
House of 40s, lotto numbers 40-49
House of 50s, lotto numbers 50-58

The House Data and Methodology

The method of calculating the data is simple. For each winning combination, the numbers are classified based on their houses. From there, we would see how often each house delivers winning numbers.

Fig 2.91 THE PROBABLE WINNING HOUSE NUMBERS

The pie chart just above shows that the probability of the 50s to win is almost the same as those of the 00s, 20s and 30s (15% – 16%); which is not far from the 40s (17%). Likewise, there's not much difference between the 40s and the 10s (18%). This only proves that any number house is as good as the other. In such case, play any number and you are good. With that in mind then, is it good to play 6 numbers which are all 10s, such as any six numbers from 10 – 19? The next set of data reveals something else.

PROBABLE WINNING NUMBERS PER HOUSE

How many numbers can probably win from each house?

The data just presented would give you an idea how many numbers from each house would probably make it to a winning combination. Would you get one number from each house; or two numbers? Let's find out.

At least one per house. Based on the data above, each house can produce at least one winning number. That probability ranges from 40% – 44%.
Two per house. Each house can also produce two winning numbers. That probability ranges from 16% – 23%.
Three per house. At rare instances, a house can produce three winning numbers. That probability ranges only from 3% – 5%.
Four per house. This is also possible but it is almost improbable with only 0.2% – 0.7% chances.
No winning number from a house. We cannot put aside, that it is also very possible that a house would not produce a winning number. That probability ranges from 27% – 34%.
Five or six numbers per house. That is very unlikely. Based on data, no house has ever produced 5 or 6 winning numbers.

Hypothetical Form of Combining Numbers

Based on the probability data just presented, when forming a combination for a lottery system 6/58 —

Based on the zero instance (27% – 34%), always exclude at least one house from your combination. Something like this: 08-17-26-35-44-45 where there is no number from the 50s.
Pick two numbers from a house (16% – 23%). Include two numbers that come from one house. Using the same example just mentioned, #44 and #45 come from the 40s. By default, if you omit one house from the six houses, one house should give two numbers.
All other houses would have one number each.

Let's prove this hypothesis by presenting another set of data.

HOUSE INSTANCES PER COMBINATION

The data just presented gives you an idea as to how many numbers from each house should form your combination. Let's examine the data starting from what is more probable.

2/H x 1. With 41% probability, this means that 41% of all sampled draw results contain 2 numbers from the same house. An example is the 08/19/25 result: 15 • 43 • 07 • 40 • 52 • 29 where #43 and #40 are both from the house of 40s while the rest are from the different other houses. The pattern would look like this: 140452.
1/H x 2. With 38% probability, this means that 38% of the 1381 results contain two numbers coming from 2 different houses. An example is the 08/17/25 result: 02 • 17 • 26 • 28 • 54 • 57 where #2 and #17 came from two different houses—00s and 10s.
2/H x 2. This case has a 36% probability. This is a form when 2 numbers come from a single house and another 2 from a another house. In other words, two doubles. Using the same 08/17 example: 02 • 17 • 26 • 28 • 54 • 57 where #26 and #28 are from the 20s; while #54 and #57 are from the 50s. In a form of a pattern, it would look something like this: 012255.
1/H x 4. Another common form at almost 28% probability, is to have 4 numbers from 4 different houses. An example is the winning numbers of 08/10/25: 15 • 13 • 47 • 30 • 57 • 03 where #s 47, 30, 57, 03 come from 4 different houses—40s, 30s, 50s, 00s; while the other two #15 & #13 come from the same house, the 10s.
3/H x 1. Here is another common form, at 27% probability, where 3 numbers all come from a single house. An example is the result of 08/26/25: 31 • 36 • 35 • 04 • 16 • 50 where the #s 31, 36, 35 all come from 30s; while the other 3 are from 3 different houses.
Two cases or scenarios are slightly common: 1/H x 3 and 1/H x 1 where 3 different numbers come from 3 different houses as in the 08/26/25 example. The 08/03/25 winning combination is an example 1/H x 1: 45 • 46 • 44 • 17 • 12 • 37 where there is a single number, #37, that comes from one house. An easy way to look at it is this way: 444113. This scenario can also look like these: 444223, 555114, 111332, etc.
0/H x 2. Half of all the results sampled (50% probability), has 2 houses excluded, which means very often, only 4 houses form a winning combination. The other cases are 0/H x 1 and 0/H x 3 where 5 houses form a winning combination; and the other case is that only 3 houses form a winning combination. In other words, the most common is 4 houses, followed by 5 houses, then 3 houses. All other cases are improbable.

Other Cases Worth Noting or Combinations You Should Avoid

6/H x 1. This scenario is considered improbable. Examples are: 20 • 22 • 23 • 25 • 26 • 29; or 31 • 33 • 36 • 37 • 39 • 38 where all 6 numbers come from a single house.
5/H x 1. There is only 1 case that this scenario happened. The winning combination of 10/26/22 was: 48 • 03 • 49 • 44 • 40 • 41 where 5 numbers are all in the 40s.
3/H x 2. This case is also rather improbable having only 1 case in existence. It happened on 10/14/24 when the winning numbers are: 46 • 40 • 41 • 19 • 11 • 16

Which house goes with which house?

Digging a little deeper, the following data reveals which set of numbers usually go with which set or house. For example, do 00s and 10s usually go together? What about 40s and 50s?

First, let me explain the labels. Combination 00s10s means combining numbers 01 – 09 with the 10s (10 – 19). Combination 20s50s means the combination of 20 – 29 with 50 – 58. And so on and so forth. The labels on the left refer to instances in a combination. For example, 12 means 1 instance from one house and 2 instances from another. Take a look at the combination with the highest value of occurrences: 10s and 50s combo 11 with 281 occurrences. This means that 10s (10 – 19) usually go with the 50s (50 - 58), each delivering one number. However, if you go down to combo 13 with only 26 occurrences, 1 number from the 10s and 3 numbers from the 50s is already rare. For example: 12 • 50 • 53 • 55.

PROBABLE COMBINATION OF NUMBERS

Significance of the Data

The data just presented allows you to delimit your choice of numbers. For example, if you are thinking of playing a combination such as: 23 26 29 40 44 46, you might want to think twice because based on statistics, this type of combination, where 3 numbers come from one house and another 3 from another house, is almost improbable. Take a look at the data labeled 33 — they are all zeroes. Though it is possible, as in the case of 10s40s which has occurred once, yet almost improbable.

The data looks overwhelming; truly it is. To make it easy for you to apply it, just take note of the zeroes and those that are less than 10 (the grey numbers).

If your combination contains 4, 5, or 6 numbers coming solely from one house, it is unlikely to win. For example: 30 31 32 33 or 20 21 22 23 24 or 1 2 3 4 5 6.
Having 3 numbers from one house is also rare but slightly probable (labels 03 and 13), However, those under labels 23 and 33 are not very probable.

Finding from Earlier Studies

Similar studies were done previously when our sampled data was still small. Let's find out if there were findings that changed.

Summary of Observations from Earlier Studies

No 6 numbers can win from one group alone. The probability is 0%. In other words, you cannot win the jackpot if your 6 numbers are any from 01 to 09 only; or 10 to 19; or 20 to 29, etc. For example, this is possible but not highly probable: 1 • 2 • 3 • 4 • 5 • 6 or 50 • 51 • 52 • 54 • 55 • 58.
Winning 5 numbers from one group alone is not also probable. It also has 0% probability.
Winning 4 numbers from one group alone is almost not probable. The probability is a very low 0.03% to 0.09%. There were only 8 instances reported out of 324 draws. This is an extraordinary case which occurs once for every 41 draws (1:41 ratio).
The probability of winning 3 numbers from one group alone is between 3.4% to 6.5% per group. Together, such case on average occurs once for every 4 draws (1:4 ratio) or 28.4% probability (92 cases over 324 draws).
The probability that 2 numbers would win from a single group ranges from 17.9% to 25% per group. All in all, such case has occurred 264 times out of 324 draws; or 81.48% probability. That is almost a 1:1 ratio (1:1.23 exactly). In other words, for every 27 draws, there are 22 instances when 2 numbers win from a particular group.
There is a strong probability that 1 winning number could come from each group. The probability ranges from 42.3% to 44.1% per group. All in all, such case has occurred 312 times out of 324 draws; or 96.3% probability. That is almost a 1:1 ratio. Exactly, that’s 26 cases for every 27 draws.
It is also possible that a group would not bring out any winning number. Such case happens when one group delivered 2 or more winning numbers. The probability of one group not producing a winner ranges from 26.9% to 33% per group. Collectively, such case has occurred 318 times, or a 98% probability; very close to 1 number winning from a single group.
In a Nutshell. There is a stronger possibility that a particular group would produce at 1 or 2 winning numbers. In such case when one group would produce 2 winning numbers, one group would produce none.
The table that follows summarizes the probability of each group to produce 1 or 2 winning numbers. Based on this table, you can already see the most probable placement of your numbers. For example, 1s are good as 1st number; or combined 1st and 2nd numbers. Your first number can mostly be 1s or 10s; while your 6th number can mostly be the 40s or 50s.
