Going around the circle, each player draws a card from the top of their deck (face-out, so that the player cannot see the card before it is played) and places that card in the center of the circle. Each player continues to place their cards in the center this way.
When a Wild Card is turned face up, the goal is to be the first person to “slap” it, or cover it with your hand. If several people slap at once, the person whose hand is most in contact with the Wild Card adds all the cards to his or her pile.
If a player incorrectly slaps a card, he or she must give the top card in his or her pile to the player who placed the slapped card. That player adds the extra card to the bottom of his or her deck.
When a player runs out of cards, the player is out—unless he or she can slap a Wild Card laid by someone else. At that point, the previously “out” player is back in and can play with the cards collected from the pile.
Play continues until one person wins all of the cards.
For a shorter version, stop play when the first person runs out of cards. Whoever has the most cards in his or her hand is the winner.
