Is this the same game as Quoridor?

It follows the documented Quoridor-style rules: a nine-by-nine board, one pawn and ten two-square walls per player, and a race to the far edge. Pawn Path Game is an original implementation with its own name, code and drawings, and it is not affiliated with the publisher of Quoridor.

How do jumps work when the two pawns meet?

When the other pawn is on the square next to yours, with no wall between you, you may jump straight over it if the square behind it is open. If a wall or the board edge is behind it, you may instead step diagonally to either side of it, as long as no wall is in that way. The Jump and Blocked jump practice positions show both: from e4 with the other pawn on e5, the legal moves are d4, e3, e6 and f4; with a wall above e5 they become d4, d5, e3, f4 and f5.

Why was my wall refused?

A wall may not overlap another wall, cross one through its middle, or leave either pawn with no route at all to its goal edge. The page checks both routes with a breadth-first search before the wall is placed, and the message says which rule the wall broke. Walls may touch end to end or meet in a T, and you need a wall left: each player starts with ten. A refused wall changes nothing, so the turn and both wall counts stay as they were.

How strong is the computer?

It is a beginner. It takes a winning move when it has one. Otherwise it compares its legal pawn moves by how much they shorten its own route and, when your route is no longer than its own, each wall by how much more it lengthens your route than its own, with walls counting for much more when you are one step from winning. It plays the best of those, picking at random between equal choices. That is one move of lookahead over at most 133 actions, so it answers after a pause of about half a second and misses longer plans. It has no rating and makes no claim to perfect play.

How does a game end, and can it be a draw?

The first pawn to reach any square on the far edge wins: rank 9 for Light, rank 1 for Dark. By this page's own convention, a game is also a draw when the same position, with the same player to move, occurs three times, or when 500 plies, single pawn moves or walls, pass with no winner. The Draw watch below the board counts both.

How are the walls named?

By the square at their lower left and a direction. d1h is a horizontal wall above d1 and e1, between ranks 1 and 2; d1v is a vertical wall to the right of d1 and d2, between files d and e. Names run from a1 to h8 because every wall covers two squares. You can type a wall name, such as d4h, into the move box instead of aiming it on the board.

Can I play with a keyboard or on a phone?

Yes. Tab to the board and use the arrow keys to move between squares; Enter or Space moves your pawn there. In wall mode, Enter or Space aims a wall at that square and a second press places it, and Escape clears the aim. Every legal pawn move is also listed as a button, 44 pixels tall on narrow screens, and you can type a move such as e2 or a wall such as d4h.

Is my game saved, and can I take a move back?

Once you play, the game, your opponent choice, your side and the hint setting are saved in this browser and come back when you return. Save position keeps one extra copy that Load saved position brings back. Undo takes back one ply between two players; against the computer it takes back the computer's reply and your move, or, if the computer is still thinking, cancels its move and takes back yours. Copy record and Download record give the full move list as text.

Can two players play this Quoridor-style game online?

Yes, in the same browser on one shared device: choose A friend and take alternating turns. The board shows legal pawn steps/jumps and rejects walls that block either player’s route. Computer mode supplies a beginner opponent when you play alone. There is no remote room, online invite or synchronized game between separate devices; the original implementation is not affiliated with the Quoridor publisher.

Moves follow Quoridor-style rules: one orthogonal step, a straight jump over an adjacent pawn when no wall or board edge is behind it, otherwise a diagonal side-step beside it where no wall is in the way; a wall may not overlap or cross another or leave either pawn with no route to its goal edge. A draw after threefold repetition or 500 plies is this page's own rule. The computer is a beginner that looks one move ahead and has no rating.
