Sliding Tiles

How to play

1. Tap a tile directly above, below, left, or right of the empty square to slide it into that space. Other tiles cannot move yet.
2. You can also focus the board and use arrow keys, or swipe on the board. The arrow or swipe moves the empty square in that direction by swapping it with its neighbor.
3. The board completes as soon as every tile and the empty square are in the correct position.

Head-to-head rules

Arrange all eight numbered tiles in order before your opponent. Both players get the same puzzle and start together, with 3 minutes to finish. Completion time decides the match; fewer moves or a higher solo score do not beat an earlier correct finish. Finishes within 0.1 seconds draw. If neither player finishes before time runs out, the match is a draw.

Your moves and answers stay private. Leaving through the game controls forfeits the match; closing the page does not pause its clock.
