- Get the tiles in order with the gap in the bottom-right corner.
🧩 Sliding Puzzle
Slide the numbered tiles into order from 1 to 8 (3 × 3) or 1 to 15 (4 × 4). Every shuffle is solvable. Count your moves and beat your best.
Sliding Puzzle
The rules in detail
The board is shuffled by making random legal slides from the solved position (150 for 3 × 3, 300 for 4 × 4), so every puzzle can be solved. Each slide counts as one move; the timer starts on your first move. The puzzle is solved when the tiles read 1 to 8 (or 1 to 15) left to right, top to bottom, with the gap in the bottom-right corner. Each size keeps its own best (fewest moves).
Tips
- Solve the top row first, then the left column, then the rest.
- Place the last two tiles of a row together: park one, then rotate the pair in.
- The 3 × 3 puzzle can always be solved in 31 moves or fewer.
