Play this traditional card game against a computer opponent. It is also known as Cat and Mouse or Skip-bo. To win this game, you must place your leftmost stack of cards on one of the three center stacks. The first card on the center stack must be an Ace, after which you can place any other card, up to and including a Queen (suits and the numbers A through Q and their values are unimportant). 

The leftmost stack, the middle five cards from your hand, and the four discard piles on the right are all available for play. When you add a card from your hand to one of the discard piles, your turn is over. 

Only the top card from your play stack, your hand cards, and the top cards from the discard piles are available for play. The King is an unrestricted value and is wild. You may play cards from your opponent's discard pile in this extreme variation.
