Thank you for your kind words!
The logic of roulette is simple: You bet on smaller or larger pools of numbers (1-2-3-4-6-12 or 18 numbers at a time), and you get (36/[count of numbers in the pool]) times your bet IF one of those numbers is rolled.
However, there are THIRTY SEVEN numbers on the wheel (including zero), making it disadvantageous for the players.
