How to play Sliding Puzzle
- Choose 3 × 3 for eight tiles or 4 × 4 for the classic 15 puzzle.
- Slide a tile next to the empty square into the gap. An arrow key or swipe moves a tile in that direction.
- Put the numbers in order from left to right and top to bottom. Leave the bottom-right square empty.
Finish the top row first, then work down. Solve the last two rows together so you can still move tiles around the gap.
What is the difference between the 8 puzzle and the 15 puzzle?
The 8 puzzle uses a 3 × 3 grid with eight numbered tiles and one blank. The classic 15 puzzle uses a 4 × 4 grid with fifteen tiles. Both end with the blank in the lower-right corner.
Can every board be solved?
Yes. Each board is shuffled using legal moves from a solved layout, so reversing those moves would solve it.
