How to use and notes

Based on Korea Lotto 6/45 (choose 6 from numbers 1-45). You can select a minimum of 3 and a maximum of 5 numbers. Your selected numbers are included and the rest are combined automatically. Selecting 3 numbers generates about 11,480 combinations. Selecting 4 generates about 820 combinations. Selecting 5 generates 40 combinations. Generation may take time when the combination count is large.

02

What is the Lotto Perfect Combination Generator?

The Lotto Perfect Combination Generator is a tool that, based on Korea Lotto 6/45 rules, automatically generates every possible combination from the core numbers you choose. For example, if you select 4 numbers, it generates all combinations (820) that include all 4 selected numbers while choosing 2 from the remaining 41 numbers. Each combination is analyzed in real time for odd/even ratio, high/low distribution, and per-decade distribution, helping you make balanced number selections. Every combination shows an AC value so you can grasp number diversity at a glance.

03

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 other lotto combination tools?
The Lotto Perfect Combination Generator produces every single possible combination that includes the 3-5 numbers you selected — nothing is left out. Rather than randomly picking a handful of results, it shows the complete set of combinations possible from your chosen numbers.
Why does selecting 3 numbers give 11,480 combos, 4 gives 820, and 5 gives 40?
Since Korea Lotto 6/45 draws 6 numbers, the tool calculates how many ways you can pick the remaining (6-N) numbers from the 45-N numbers not yet chosen. Selecting 3 leaves 42 numbers to pick 3 from (42C3=11,480), selecting 4 leaves 41 to pick 2 from (41C2=820), and selecting 5 leaves 40 to pick 1 from (40C1=40).
How many numbers can I select?
You can select a minimum of 3 and a maximum of 5. Selecting all 6 would leave nothing to combine, so 5 is the cap, while selecting fewer than 3 would generate too many combinations, so 3 is the minimum.
What do the odd/even, high/low, and number distribution shown for each combination mean?
They're statistical balance indicators shown for every generated combination — the even/odd ratio, high/low ratio, and distribution across the 1-9, 10s, 20s, 30s, and 40s ranges — so you can pick out combinations closest to the balance you want.
What should I do if I get a warning that there are too many combinations?
Selecting just 3 numbers generates 11,480 combinations at once, which can take longer to process. If you see the warning, add one more number to narrow it down to 4 or 5 selections for faster generation and a more concise result.
