About Sliding Puzzle
The sliding puzzle — famously the 15 puzzle — is a timeless classic: use the empty space to slide numbered tiles into order. Simple rules, real planning required.
Three sizes await: a relaxed 3x3 (8 puzzle), the classic 4x4 (15 puzzle), and a challenging 5x5 (24 puzzle). Every shuffle is guaranteed to be solvable.
Your fastest time and fewest moves are saved separately for each size. You can even slide several tiles in a row at once — master it and chase your records.
Tips & Strategy
- Don't shuffle randomly; solve the top row and left column first, then you'll have free space to maneuver the rest of the tiles.
- The last two tiles of each row must be placed together to avoid a lock — learn to stack the pair and rotate them into place as a unit.
Frequently Asked Questions
How do the tiles move?
Tap any tile in the same row or column as the empty space and it slides toward the gap. On desktop you can also slide tiles with the arrow keys.
Can I slide several tiles at once?
Yes, you can push multiple tiles in the same line in one action. Just note that it counts one move per tile slid, which matters if you're chasing a record.
Could a shuffle be unsolvable?
No — every shuffle is guaranteed solvable, so you can dive in with confidence. Choose from 3x3 (8 puzzle), 4x4 (15 puzzle), and 5x5 (24 puzzle).

Before your first round
Plan the position of the empty cell as carefully as the numbered tiles. Complete the top row and left column to reduce the working area. Sliding several tiles together can be convenient, but each moved tile affects the move count; time and move records measure different things.
