Ultra Lotto 6/58 Probability Charts

All in all, there are six (6) number groups namely: 01s, 10s, 20s, 30s, 40s, 50s. From these 6 groups, you can form 46,656 patterns. As of this writing, only 210 of 46,656 patterns are active; 93 of them have been used more than once. One pattern has been used 10 times; while the rest, 2 to 8 times. From time to time, a new pattern would emerge in about 1 for every 4 draws (1:4).

The winning frequency of each pattern is not that significant to guarantee winning. The best thing that can be done, is to just figure out the most probable sequences.

To guide you on how you can maximise the benefits of probability, I have provided here two probability charts: the Single Pairs Color Chart and the Probable Triads Chart. Let’s now combine all the probable patterns to form a fewer pattern combinations.

Single Pairs Color Chart

The Single Pairs Color Chart shows only the most probable patterns. Based on probability, 45.5% of the results contain a single pair, that is, two numbers winning from the same group. Use this chart to guide you when forming your combinations.

If you find these combinations difficult or confusing to remember, simply follow these rules:
  • Notice that each pattern in the chart contain a color that appears twice, which means there always exists where 2 numbers come from the same color or group. In other words, a color may or may not be repeated.
  • If a color is not repeated, what usually follows is the next group nearest to it. For example, 10s always succeed the 1s; after 10s, 20s comes next; after 20s, 30s comes next and so forth and so on. The only exceptions are the reds and greens.
    • Orange or yellow may come after red; that is the 10s or the 20s may come after the 1s (1-9).
    • If green is in the 5th position (i.e. a number from the 30s is in the 5th position), what follows is either the 40s or the 50s.

Probable Triads Chart

As mentioned previously, single pairs make 45.5% of the results. However, there’s the other side of the coin; which is the 52.1% wherein two groups would produce 2 winning numbers each. For the reason that this type of pattern would result to a long list in a color chart, I have devised a Probable Triads Chart wherein you can mix and match the most probable triads. A triad is a common sequence of 3 lotto number groups.


The triads chart is arranged according to the most probable rates. The triads on top are the most probable ones. The other triads that are not shown are those that only have 2.2% or lesser probability.

The Columns

The letters in the columns refer to the position of the lotto numbers if arranged numerically from lowest to highest. Thus;
  1. A is the 1st lotto number (smallest or lowest in the combination)
  2. B is the 2nd lotto number
  3. C is the 3rd lotto number
  4. D is the 4th lotto number
  5. E is the 5th lotto number
  6. F is the 6th lotto number (largest or highest in the combination)
Therefore, column ABC refers to the first 3 lotto numbers. BCD would be the 2nd to 4th numbers; CDE, the 3rd to 5th numbers; and DEF would be the 4th to 5th numbers.

The Patterns

Under each column, you’ll find a pattern of numbers. Each number refers to a successive set or group of numbers. In the previous section, we assigned these groups a color.
  • 0 refers to numbers 01 - 09 (reds or 1s)
  • 1 refers to numbers 10 - 19 (oranges or 10s)
  • 2 refers to numbers 20 - 29 (yellows or 20s)
  • 3 refers to numbers 30 - 39 (greens or 30s)
  • 4 refers to numbers 40 - 49 (blues or 40s)
  • 5 refers to numbers 50 - 58 (purples or 50s)
So, 011 would be a number 01 - 09 followed by any 2 numbers from 10 - 19. For example, 03 • 15 • 18. You will find this under column ABC; but you’ll also find this under BCD. This means that the same pattern can be in different positions. In this example, 01 • 03 • 15 • 18 • 21 • 33, the numbers 3, 15 and 18 are in the 2nd to 4th positions (BCD). In another example, 03 • 15 • 18 • 21 • 33 • 58, the same numbers are in the 1st to 3rd position (ABC).

How To Use The Triads Chart

To use this chart, follow these procedures.
  1. Select a triad from column ABC. For example, 011.
  2. Under column BCD, find a triad whose first 2 digits correspond to the last 2 digits of your triad under ABC. For example, 112. BC in both triads is 11. If you are going to combine the two, it would be ABCD or 0112.
  3. Match the last 2 digits of your triad under BCD with the first 2 digits of a triad under CDE. In our example, our last 2 digits are 12. Under CDE, we find 123. Your pattern is now 01123.
  4. Follow the same procedure. Match the last 2 digits of your triad in CDE with the first 2 digits of a triad in DEF. This will complete your 6-number pattern. In our example, our last 2 digits are 23. Under column DEF, we find 234. Your patterns in now complete 011234 (derived from 011 112 123 234).
  5. Based on the pattern you just formed, substitute it with the applicable lotto numbers. For example, if the pattern formed is 011234, a possible combination is 03 • 15 • 18 • 21 • 33 • 45.


  • You don’t have to begin always at column ABC. To give a variation, you may pick a triad first from column CDE, BCD or DEF.
  • When forming a pattern, you may encounter more than one triad. For example, under CDE, you have both 234 and 233. It’s up to you which one you choose, or you can use both in two different combinations.
  • In some cases, you may encounter a dead end wherein your last 2 digits do not match any 2 digits in the triad column. In such case, just pick any triad; or you can be adventurous to pick a triad that is not listed. An example would be 001 (BCD); there is no triad in CDE that begins with 01.
  • Another variation is to form patterns based only on 3 columns. For example, ABC BCD DEF.
  • Also another variation is to match only the last digit with the first digit of another triad.
