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

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).
