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.
Can every board be solved?
Yes. Each board is shuffled using legal moves from a solved layout, so there is always a path back.
