How to play and game rules
- Put the tiles in order from 1 to the last number, left to right and top to bottom, with the gap in the bottom-right corner. Sizes are 3×3 (easy), 4×4 (medium) and 5×5 (hard).
- Click a tile in the same row or column as the gap: the whole line between them shifts towards the gap, like the physical puzzle. Each tile shifted counts as one move.
- With the board focused, arrows or WASD move the adjacent tile in that direction towards the gap: the up arrow raises the tile below the gap. On mobile you can swipe within the board.
- Tiles already in their correct position are marked with ✓ and a colored border. Undo keeps up to 100 steps while the game is unfinished.
- Every board is generated by shuffling from the solved state, so it always has a solution. The daily board is the same for everyone.
- Daily: one scored game per UTC date, changing at 00:00 UTC (19:00 in Panama). Unfinished games expire at the next challenge and finished games cannot be restarted.
- Unlimited games keep separate statistics. Only finished games count. Changing language preserves progress. Data stays in this browser and domain; clearing site data removes your history.
