墙棋（Quoridor）是一款经典的抽象策略棋类游戏，由Mirko Marchesi在1997年设计。游戏中通常有2到4名玩家参与，每个人控制一个棋子，目标是最先到达对方边界的任意位置。

基本规则如下：

棋盘：标准的墙棋棋盘是一个9x9的网格。
棋子：每个玩家有一个棋子，棋子的起始位置在棋盘中央附近，具体位置取决于玩家人数。
目标：玩家的目标是让自己的棋子到达对方棋盘边缘。也就是说，对于2人游戏，玩家需要到达对方的底线；对于4人游戏，则需要到达对面的边线。
移动规则：玩家可以按照以下两种方式移动自己的棋子：
前后左右移动一格。
跳过一个相邻的棋子到对面的空格（类似于国际象棋中的骑士移动）。
墙：每位玩家一开始会有一定数量的墙（通常是10个），这些墙可以放置在棋盘的格线之间，用来阻挡对手的路径。放置墙的时候必须垂直或水平放置，且不能覆盖棋盘上的其他墙或棋子。
特殊规则：墙不能完全封闭某个玩家的棋子，每个玩家必须始终至少有一个移动的路径。
结束游戏：第一个到达对方边缘的玩家获胜。

Quoridor is a classic abstract strategy board game designed by Mirko Marchesi in 1997. It is typically played by 2 to 4 players, with each player controlling a pawn, and the objective is to be the first to reach any position on the opponent's edge of the board.
Basic rules are as follows:
1. **Board**: The standard Quoridor board consists of a 9x9 grid.
2. **Pawns**: Each player has one pawn, which starts near the center of the board, with the exact starting position depending on the number of players.
3. **Objective**: The goal for each player is to move their pawn to the edge of the board opposite their starting position. In a 2-player game, this means reaching the opponent's baseline, while in a 4-player game, it means reaching the opposite side of the board.
4. **Movement**: Players can move their pawn in one of two ways:
- Moving one space forward, backward, left, or right.
- Jumping over one pawn to the next immediate empty space, similar to a knight's move in chess.
5. **Walls**: Each player starts with a certain number of walls (usually 10), which can be placed between the lines of the board to block the paths of opponents. Walls must be placed vertically or horizontally and cannot overlap other walls or pawns on the board.
6. **Special Rules**: Players must always have at least one possible path to move; walls cannot completely block a player's pawn.
7. **End of Game**: The first player to reach the opponent's edge of the board wins.
Variants of Quoridor may have adjustments to the rules, such as changing the size of the board, the number of walls, or the movement rules, but the basic gameplay spirit and strategy remain the same.
