What is the Fixed-Number Lotto Combination Generator?

This generator lets you first pick 12 or 20 fixed numbers, then produces all possible combinations of 6 from them. Picking 12 yields 924 combinations and picking 20 yields 38,760 combinations, and you can narrow down to the desired count using filters such as high AC priority, balanced odd/even ratio, and minimized consecutive numbers. It is useful when you trust certain numbers but are unsure which combination is best, or want to build combinations within a specific number range.

What is AC (Arithmetic Complexity)?

AC (Arithmetic Complexity) is an indicator of the diversity of a lotto number combination. It measures the number of unique differences by calculating the difference of each number pair. Example: [1, 2, 3, 4, 5, 6] → differences 1,2,3,4,5 → AC=5 / [1, 11, 21, 31, 41, 45] → differences 4,10,14,20,24,30,40,44 etc → AC=13. Generally, a higher AC value means numbers are spread more evenly, while a lower AC value means numbers are more consecutive or regular.

Frequently asked questions

How is this different from the Lotto Perfect Combination Generator?

The Perfect Combination Generator locks in 3-5 core numbers that must appear in every combination. This tool instead builds a pool of 12 or 20 numbers first, then generates every possible 6-number combination drawn from that pool — you're not fixing specific numbers, you're casting a wider net of trusted numbers and picking combinations from within it.

Why does picking 12 numbers give 924 combos and picking 20 give 38,760?

The tool calculates how many ways you can choose 6 numbers from your pool (nC6). Choosing 6 from a pool of 12 gives 12C6=924 combinations, and choosing 6 from a pool of 20 gives 20C6=38,760.

There are too many combinations — how can I narrow it down?

You can specify the number of combinations to generate directly, or combine the three filters — prioritize high AC, balanced odd/even ratio, and minimize consecutive numbers — to filter down to just the results you want.

Should I pick 12 or 20 numbers?

Pick 12 if you have relatively few trusted numbers and want an easier-to-manage combination count. Pick 20 if you want to explore a wider range of combinations — since 20 generates far more combinations, using the filters actively is recommended.

What exactly does the "minimize consecutive numbers" filter do?

Enabling this filter reduces the share of combinations with sequences like 1-2-3, showing results weighted toward combinations where numbers are more evenly spread out.
