War (Card Game)

Deal the entire deck evenly between two players, face down, without looking at the cards.

Both players flip their top card face up at the same time.

Whoever flips the higher-ranked card wins the round and collects both cards, placing them at the bottom of their pile.

If both cards match in rank, it's a "war": each player lays down a few cards face down, then flips one more face up, and the higher card wins all the cards in play.

Continue until one player collects the entire deck.
