War
- Objective: Win all 52 cards.
- Setup: 2 players. Deal the entire 52-card deck evenly, face down. Each player has a 26-card deck and must not look at them.
- Gameplay: Both players simultaneously flip their top card face-up.
- Battle: The player with the higher card wins both cards and adds them to the *bottom* of their own deck. (Card ranks: Ace is high, 2 is low).
- 'War': If the two cards are of equal rank, 'War' is declared.
- War Rules: Each player places 3 cards face-down (the 'spoils') and then flips a 4th card face-up. The winner of this face-up card (high card) wins *all 10 cards* (the 2 original tied cards, the 6 face-down spoils, and the 2 new face-up cards).
- Multiple Wars: If the 4th cards also tie, the War repeats: 3 more down, 1 more up. This continues until a player wins.
- Winning: The game ends when one player has collected all 52 cards.
