Shuffle the deck and deal all cards evenly to each player
Keep your cards face down in a single pile
Both players reveal the top card at the same time
The higher card wins the round
The winner takes both cards and places them at the bottom of their pile
If the cards are tied, start a war
During war, each player places three cards face down
Each player then reveals a fourth card
The higher fourth card wins all cards in the war
If the fourth cards tie again, repeat the war
Continue playing until one player has all the cards
The player with all the cards wins the game
