You know where the ball is before you start the game. And then the computer will change the positions of the three cups randomly and quickly. You need to rest your eyes on the right cup closely otherwise you are easy to guess wrong. Or if you are lucky, you can still guess right. If you can tell where the ball is after the changing, you get the money you’ve bet otherwise you will lose it. Good luck!
