How to Play Quoridor

The complete rules for standard 2-player Quoridor.

Objective

Each player controls one pawn. The goal is to be the first to move your pawn to any cell on the opposite side of the board. SOUTH starts on row 1 and must reach row 9. NORTH starts on row 9 and must reach row 1.

Setup

  • 9×9 board with 81 cells
  • Each player starts in the middle of their back row
  • Each player receives 10 walls
  • SOUTH moves first

On Your Turn

On each turn you must do exactly one of two actions:

Move Your Pawn

Move to an orthogonally adjacent cell (up, down, left, right) that is not blocked by a wall. You may jump over your opponent if they are adjacent and there is no wall behind them. If there is a wall behind them, you may jump diagonally.

Place a Wall

Place one of your remaining walls on the board. Walls span 2 cells and can be horizontal or vertical. A wall cannot be placed if it completely blocks either player from reaching their goal row.

Wall Rules

  • ✓ Walls occupy the gaps between cells, spanning exactly 2 cells
  • ✓ Walls can be horizontal (blocking north-south movement) or vertical (blocking east-west movement)
  • ✓ Two walls cannot overlap or cross each other
  • ✗ A wall placement that leaves any player with no possible path to their goal row is illegal
