Slide 15 Online
Slide 15 is the classic sliding number puzzle: put the tiles back in order, 1, 2, 3 and on, with the gap in the last corner. Start on the little 3×3 board, move up to the real 15 puzzle and then 5×5 — and try to match par, the shortest solution.
Tiles are coloured by the row they belong in, and a white dot marks every tile already home.
Tap any tile in line with the gap and the whole row or column slides at once.
Every 3×3 and 4×4 level has par worked out by a solver as the shortest possible solution.
Levels 1–7 are 3×3, levels 8–40 are 4×4 and from level 41 it's 5×5.
Three stars for finishing within 15 % of par, two for twice par.
How to play Slide 15
Put the numbers back in order:
- Tap a tile next to the gap to slide it in.
- Tap further along the gap's row or column to slide several at once.
- Or swipe toward the gap, or use the arrow keys.
- Solve the top row first, then the next, and finish the last two rows together.
- Beat par for three stars.
Desktop: Click a tile, or use the arrow keys.
Mobile: Tap a tile or swipe toward the gap.

Tips for Slide 15

- The white dots show which tiles are already home — try not to disturb them.
- Row colours tell you where a tile belongs at a glance.
- Sliding a whole line at once counts one move per tile.
