In this article, you can read about the basic rules of the game Quoridor and learn how to play. The object of the game is to be the first player to reach any square on your opposite side of the board.
Give each player an even number of wall pieces, discard any remainders. Each player starts with their pawn on their corresponding first-row middle square. In a two-player game, players start on opposite sides. On your turn, you may either move your pawn 1 square in each direction. Meaning, forward, backward, right or left or you may place a wall. Pawns may not move through walls.
You may place walls lengthwise not heightwise covering two full squares. Secondly, you may not place walls partially covering a square nor partially off the board. Lastly, you must place walls in a way so that each player always has an available path to their opposite side of the board. You may jump opponent’s pawns landing on the space behind it. However, if that space is blocked by a wall or pond you take the available space of your choice to either the right or left of the jumped pawn. You cannot jump upon if a wall separates you. The first player to reach any square on the opposite side of the board from their starting square wins.
I also made a gameplay video where I show you rules of the game Quoridor as I play.
