War

Overview

War is a classic card game for two players. It is a simple, luck-based game where the goal is to win all 52 cards in the deck.

Setup

•
Players: 2
•
Deck: A standard 52-card deck (no Jokers).
•
Card Rankings: Aces are highest, followed by King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, and 2 (lowest). Suits are ignored.
•
Dealing: The deck is shuffled and dealt evenly so each player receives 26 cards in a face-down pile.

How to Play

1.
The Flip: Both players reveal the top card of their deck simultaneously.
2.
The Capture: The player with the higher-ranking card wins the round and takes both cards, shuffling them into the bottom of their deck in no fixed order — just as you would when scooping them up off the table.
3.
Repeat: Players continue flipping until a tie occurs.

Declaring War

When both players flip cards of the same rank, a War is declared:
1.
Each player places the next three cards from their deck face-down on the table. If a player has fewer than three cards remaining, they place whatever they have.
2.
Each player then flips one more card face-up.
3.
The player with the higher face-up card wins the War and collects all cards on the table (the tied cards, the face-down cards, and the final face-up cards), again in no fixed order.
4.
Double War: If the new face-up cards also tie, the War process repeats until one player wins the pile.
5.
If a player runs out of cards during a War and cannot flip a face-up card, the other player wins.

Winning the Game

The game ends when one player has collected all 52 cards. That player is the winner.
Why won cards go back in no fixed order. It is not a flourish — it is what guarantees the game ends. If the winner always returned cards the same way, the deck would be a deterministic machine with only so many arrangements, so a deal would have to either finish or fall into a loop that repeats forever. Measured over 300 deals, about one in six looped and never finished. Returning the won cards in no fixed order is how a real table avoids that, and with it every one of those 300 deals finished — with a median of 188 rounds.
