There are 12 cards marked 1 to 12. They're arranged at random, and neither you, nor the AI knows which one is next. First, you draw a card. Then, you predict whether or not the next card will be higher or lower than the one you drew. Then, you bet a percentage of your money (starting at £100) on whether it will be higher or lower, If you win, you get this amount doubled, if you lose, you lose it. Cards never repeat, and you just need to run out of cards.
I believe I have made a Higher or Lower-playing AI that is flawless. You can play the game as well, to see how much money you can get, and how much the AI gets. It's impossible, given the uncertainty, to make more rational decisions than it does. With a sufficiently large user-base, I want to measure how rational you all are. I credit myself entirely.
