Played in landscape mode, the game is simplicity itself: three cups and a pea. You're shown the pea's location, and the cups start moving. When they stop, you point to where the pea ended up. The action speeds up as you move into higher levels, and you can miss three picks before the game starts over again at level 1.
If the animation is not snappy enough u can make it smaller [ ctrl - ], it'll make it faster.
