Four corners, twenty-four treasures and a board that changes shape every turn. You push the spare tile in at an arrow, a whole row or column shifts, and the corridor you were going to walk is somewhere else. Then you move.
Tap the spare tile to rotate it, then tap one of the twelve arrows to push it into that row or column. Everything on that line moves one square and the tile that falls off the far end becomes the new spare. The arrow that would undo the previous player's push is shut for your turn.
Move your pawn any distance along connected corridors, or press Stay put and go nowhere. The reachable squares are outlined for you. Pawns pass through each other and can share a square.
Only the top card of your pile is in play. Land on the treasure it shows and you claim it and turn up the next one. A pawn pushed off the edge of the board comes back on the tile you just inserted, and that does not use up your move.
Once your last card is gone, the only thing left is the coloured corner you started on. The first player who collects everything and gets home wins, and the game stops there.
The original
That sentence is printed under the board in the game and it is here for the same reason. The repository calls this a fan-made, non-commercial homage for personal play. It is free, there is nothing in it to buy, and the board game it is built on is somebody else's design.
The board
Sixteen tiles are fixed: the four coloured corners plus twelve treasure T-junctions in the rotationally symmetric arrangement the printed board uses. Thirty-four more are loose, thirteen straights and fifteen corners and six treasure T-junctions, with twenty-four treasures spread across the fixed and the loose ones. Thirty-three of the loose tiles are shuffled onto the board and the last one is the spare you start pushing.
Labyrinth runs in a browser tab, free, and there is nothing in it to buy.
No account, no advertising, nothing for sale, and no network request once the page has loaded. It writes nothing to your browser either, so there is no saved game to lose and nothing to clear. It is a fan-made digital homage to Ravensburger's Labyrinth by Max J. Kobbert, and it is not sold.
