Jackpot numbers. All the lotto numbers drawn to win the jackpot prize; all of the winning numbers. For example, for lotto systems 6, a player should match all the the 6 lotto numbers drawn in order to win the jackpot prize.
Lotto results. The results of a lotto drawing. The numbers that are drawn out from a lotto draw or drawing. The jackpot numbers or winning numbers. Also called the draw results or results of the drawing.
Odds of winning. The chance of winning. Also the probability of winning.
Hit. A hit is a match. You hit a number if one of your numbers matched any of the jackpot numbers.
Hit interval. The recurrence of a hit for every “x” number of draws.
Frequency. The number of times a certain number or event occurs. For example, the frequency of a lotto number to be drawn repeatedly.
Combo-5. Any combination comprising 5 numbers taken or extracted from a jackpot number or any 6-number combination. Any 5-number combination. A set of 5 numbers.
Combo-4. Any combination comprising 4 numbers taken or extracted from a jackpot number or any 6-number combination. Any 4-number combination. A set of 4 numbers.
3-somes. Any combination of 3 numbers that usually are drawn together. Sticky threes.
Hot pair. Any combination of 2 numbers that usually stick together.
Clusters. A group of lotto numbers that usually stick together and so are presumed that these numbers belong to a particular set of lotto balls.
Seed numbers. These are numbers 1 to 9. Every number has a seed number. If a number has 2 or more digits, the digits are added until reduced to its seed number. For example, the seed number of 48 is 3 reduced as follows: 4 + 8 = 12; 1 + 2 = 3.
Hot numbers. These are numbers that are frequently recurring in a given period. Numbers that frequently win or drawn.
Cold numbers. These are numbers that are not being drawn for a longer period.
Sum. The sum of the 6 lotto numbers when all added up.
Lower limit. The lowest possible number within a ±90% range or scope of higher probability. In some cases, the percentage may vary.
Higher limit. The highest possible number within a ±90% range or scope of higher probability. In some cases, the percentage of range may vary.
Odd-Even ratio. The ratio of odd lotto numbers to even numbers in a 6-number combination.
Distance. The calculated difference between two adjacent lotto numbers assuming a numerical order of the lotto numbers.
Sum of distance. The calculated distances of the numbers in a lotto combination all added up.
PNN. Probable next number. The lotto number that may probably follow another number assuming the numbers are arranged numerically. For example, if the first lotto number is 8, what higher number can be probably next?
Number groups. A variety of ways to group the system lotto numbers. For example, line groups and seed number groups. The purpose of number groups is to determine how the lotto numbers evenly or unevenly distributed to the groups.
Line group. Arranged in numerical order, all the lotto numbers divided and grouped equally. For example, for lotto 6/55, the numbers 1 to 55 are divided into 5 groups wherein each group consists of 11 numbers.
Seed number group. A group of numbers based on their seed number.
Trend. A lotto number or a group of lotto numbers that show a certain pattern or behavior. For example, numbers that tend to rise or turn cold, or numbers that tend to cluster.
Repeater. A number drawn from two or more consecutive draws. A number drawn again from the last draw. A repeating number.
Number pattern. Two numbers or more that show a certain or unique relation or common characteristic. For examples, 12-21, 6-9, 11-22, 1-3-31, 19-29.
Inverse pattern. A pattern in which one number is the reverse of the other in position or order of digits. Also called a mirror pattern. For example, 24-42.
Doubles. Two numbers wherein each number has the same digits. For example, 11-22.
Sequential numbers. Two numbers in which one number is the number right before or after the other as far as counting numbers are concerned. For example, 25-26.
Math numbers. A group of numbers that resemble an equation or formula. For example, 3, 4, 7 (3 + 4 = 7) or 5, 6, 30 (5 x 6 = 30) or 7, 10, 17 (7 + 10 = 17).
Population. It refers to all the results of lotto draws.
Sample size. In principle, it refers to a portion of the population. However, if the population can all be accounted for, as in the case of the lotto draws covered here, the sample size covers the whole population.
Margin of error. In statistics, it measures the reliability of the probability findings.  


Grand Lotto 6/55 Repeaters: How Often They Occur

In some instances, a jackpot number from the draw that just preceded wins again on the next draw. That number is called a repeater. A repeater is a number that wins consecutively.

How often does a repeat occur? Based on the data that follows, half the time, a number is not repeated (48%); and at almost equal time, it is repeated (52%).

Lotto 6/55 Frequency of Repeats
353 100%

How many numbers are often repeated? Most of the time, only one number is repeated (40%). At very rare times that 2, 3, or 4 numbers are all together repeated.

When does a repeat recur? Examine the next table of data. A repeat may recur after 1 to 7 draws; but often times just 1 draw after or immediately after (0). On the other hand, a no-repeat recurs after 1 to 8 draws; but most often within 2 draws or immediately after (0).

Lotto 6/55 Recurrence of Repeats vs No-repeats
RepeatsNo Repeats

To repeat or not to repeat – that is the question. A number is repeated, on average, every 2 draws. Likewise, when it's not repeated, it also occurs every 2 draws. To capture both probabilities, you may play 2 tickets – one with a repeater; the other with no repeater.


Lotto Trends Calculator - A Lotto Tool

It would be interesting to know what's trending on all lotto games in order to give you an idea how numbers would come out in the next draws. I have proven in my analysis of data previously that not that is all hot would come out in the next draws. One hot number could come out but not all and not every time. It's more like a mix of hot and average numbers, and at rare times, with one cold number.

Lotto Trends Calculator - A Lotto Tool

I created this tool which collects all lotto results within a one-month period. The results cover four 6-ball lotto games such as lotto 6/42, 6/45, 6/49, and 6/55. The purpose of this tool is to find out what's frequently coming out from all the draws. For example, in March 2012, the numbers 13 and 33 were busy numbers being drawn 13 times each. It's not a bad idea to play these numbers together or separately. The next challenge, however, what other numbers would you combine with these hot numbers. There are many choices. Whew! But at least, you could avoid what's cold.

If you would observe every day, for at least a month, how numbers would come out, more or less, the trends would give you an idea how you would combine your numbers. You can use this tool to help you. All you have to do is to enter the results on the sheet provided. If you have online access to a results archives, a copy and paste makes your job easier.

You can download this tool at (not available at this moment).


Do Lottery Results Form A Certain Pattern or Trend?

Could it be possible that lotto winning numbers form a certain pattern or trending from which you can predict the next winning numbers? There's only one way to find out. Gather a sample of lotto results, study them and calculate.

The subjects of this study are four lotto games: 6/42, 6/45, 6/49, and 6/55. To play these games, you pick 6 numbers out of 42, 45, 49, or 55 consecutive numbers beginning from number 1. Depending on your area, you may win a prize if you matched at least 3 numbers.

For each lotto game, except 6/55, I sampled more than a thousand jackpot numbers. The table below shows the number of each sample and the margin of error.

LottoSampleMargin of Error

The margin of error can range between 1% and 10%. In Statistics, the larger the size of the sample, the closer its characteristics would be to the characteristics of the entire population.


Winning numbers are mechanically drawn from a tumbler using air pressure that blows the ball up and out of the tumbler. If the balls have varying weight, the lightest balls would always win. For that reason, all balls weigh almost precisely equally. There are other factors that may affect the drawing of a ball. These are humidity, dirt, paint, perspiration, and pressure. In this study, we will disregard these factors for the reason that we can not gather data related to these.

Provided that your local lotto system uses the same drawing method mentioned previously, we can assume that our findings may be close to your own lotto system. If you wish to be more precise, you can use a tool that allows you to enter the history of lotto drawings in your own area. You can download this tool at lottotips.amikvs.com.


The method by which the data are examined uses simple collection and calculation of data often aided by a software program. The program performs mathematical procedures and statistical queries that quickly produce information like probability rates, among others. No complicated statistical or mathematical formula were used to analyze the data.

Randomness of Lotto

The results I found out in this study are interesting. What's even more interesting is how future drawings contradict what's more than probable. For this reason, sometimes you have to think out of the box when playing this game. The randomness of lotto is hardly predictable. It is elusive. It's like it has a mind of its own and doesn't want to be discovered. It's like once a secret is revealed, it plays a trick to discourage you and make you believe that you are wrong. Nevertheless, it keeps challenging you.


Lotto Checker - A Helpful Lotto Tool

What is Lotto Checker?

It is a lotto tool that checks a database of lotto results to find out if your lotto numbers had won in the previous drawing. What's the use of this?

Based on probability data, jackpot numbers are unique. That means, jackpot numbers are not repeated even if you combine all the lotto results from all 6-ball lotto games.


The fact was true until October 11, 2006 when the jackpot numbers drawn on September 22, 1999 were drawn again on October 11. Nevertheless, it happened only once so far - a probability of 1 out of 5,782 draws.

Considering that, it is still safe to play unique numbers. To help you ensure that you're not playing jackpot numbers again, this Lotto Checker comes handy. This Lotto Checker is linked to a database of Lotto Results, which you can also download at this blog's (not available at this moment).

The 6-ball lotto games cover only lotto 6/42, 6/45, 6/49, and 6/55.

Where To Download

You can download the Lotto Checker at (not available at this moment). You should also download the 4 databases of Lotto results in order for Lotto Checker to work. When you use Lotto Checker, all files, which are spreadsheets, must be open to see the result.

Winning 5 Numbers Are Rarely Drawn Twice

There's also a low probability that 5 of the jackpot numbers be drawn more than once. Lotto Checker also checks that information.

With Lotto Checker, your wide choices of lotto combinations are narrowed down which is helpful.
