There is a ball hidden under the cup with a number on it. Select your number with over or under and place your bet. Simple!
We also have two other games, Schrodinger's ball, our take on coin flip and 3 Cupz a two or three player game where you guess which cup the ball is hidden under. Play against other Steemians for that extra bit of excitement.
