Objective: Get rid of all your cards.
Setup: See above.
Rules: After the game is set up, each player flips the top card off their draw piles. Any card one higher or lower than the top card on each pile can be played. Each player plays cards on both piles. Doubles in the player's hand can be placed together so more cards can be flipped face up. When no cards can be played on the draw piles, another card is put on top of the pile and play continues. When one player is out of cards, they slap one of the face-up piles (preferably the smallest one) and takes those cards. The game continues in the same way until one player has no more cards.
