I'm making a Bitcoin gambling game with some developers. But I need help from you crazy good mathematicians out there! I need to know the "kelly criteron" or "EV" of the possible outcomes in the game. How the game works: The game is basically a grid of 1-100 numbers. Every 10 seconds a number range will be generated. So you choose to bet on 40-60 so that the generated range won't crash into your bet range. You will get a 250% payout. 200% for the 20 numbers. 50% for the 5 prime numbers in there. So prime numbers are your friend! You can also click once on any number. If you click on a prime number you are betting the generated range will not crash into at least 1 prime number, if you're correct you will get a 112.5% payout. If you click on only one even or odd number you're betting there will be more of that number (even or odd) in the total range that is not crashed into. So If I click on an even number and the generated range is 21-31 I will win, the payout would be 150%. Because between 21 and 31 there are more even numbers.
