Simplify any lottery to a matter of just picking 1 number out of every possible winning number combination. Example: Instead of picking 6 numbers from 1-49 you can simply pick one number between 1 - 13,983,816.
This is much more representative of your overall odds of winning the jackpot and allows a new way to spread out your picks when playing multiple tickets.
How it works: Every possible combination of numbers is organized in lexicographic order and assigned an incrementing value. So in a 6/49 style lottery the first number set is 1,2,3,4,5,6 the second is 1,2,3,4,5,7 the third is 1,2,3,4,5,8 the 200th is 1,2,3,4,9,39...etc.
