War is one of the first card games we played as children. Here's a refresher on how to play.
Number of players: Best for two. More can play, but the cards may not be distributed evenly.
Object: To win all the cards.
The cards: A standard 52-card deck. Aces are high. Suits have no ranking.
Dealing: Shuffle the cards and deal them one at a time into stacks for each player. Place the cards facedown in front of each player.
Playing: Each player turns over the top card of their stack. The highest card wins the turn. The cards you win are put underneath your stack. When two players turn over cards of the same rank, the "war" begins.
Each player then puts three cards from their stack facedown on the table and turns the next card faceup. Whoever turns up the highest card wins all the cards from the war. If there is a second tie, three more cards are added, and the process is repeated.
The game is over when one player has all the cards.
