Quoridor is an abstract strategy game for 2 or 4 players. Each player tries to move their pawn across a 9x9 board to the opposite side. On each turn, a player either moves their pawn one space or places a fence to block opponents. Fences cannot completely block access to the goal – a path must always remain open.
| Component | Quantity |
|---|---|
| Game board (9x9 grid) | 1 |
| Pawns | 4 (1 per player) |
| Fences (wooden walls spanning 2 squares) | 20 |
On your turn, choose one action:
When you have no fences remaining, you must move your pawn.
Move your pawn exactly 1 square horizontally or vertically (forward, backward, or sideways). Pawns must navigate around fences.
Place one fence between 2 sets of 2 squares. Fences can facilitate your own progress or impede your opponent. Critical rule: You must always leave at least one path open for every player to reach their goal line. A fence placement that would completely block any player is illegal.
When two pawns are on neighboring squares with no fence between them, the active player may jump over the opponent’s pawn, landing on the space directly behind them. This advances the jumper an extra square.
If there is a fence behind the opponent’s pawn (blocking the jump-through), the active player may instead move to the left or right of the opponent’s pawn.
In the 4-player game, you may not jump more than one pawn.
The first player to reach any of the 9 squares on the opposite side of the board (the line furthest from their starting position) wins.
