Generate combinations from your chosen numbers
Pick 3-5 numbers and the rest are auto-filled to generate every possible combination.
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.
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.
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] β differences 1,2,3,4,5 β AC=5 / [1, 11, 21, 31, 41, 45] β differences 4,10,14,20,24,30,40,44 etc β 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.
