WAR!
2 or more players
Equipment needed: 1 or more decks of cards
Divide the cards evenly among the players. Each player turns up the top card from his or her deck and the highest value wins. (Note: Ace is high card, but a 2 is the only card that will beat it.) The winning player takes all the upturned cards and adds them to the bottom of his or her own deck. In the event of a tie, those two players go to "war." Each plays three more cards face down, then turns the fourth face up. The highest of these cards claims all the upturned cards plus those that were played facedown. Continue until one player has all the cards.
