Sliding Number Puzzle
Slide the fifteen tiles into order. Every shuffle is guaranteed solvable. Four difficulty levels.
Put the tiles in order with the gap at the bottom-right.
How to play
- Click a tile next to the gap (or use the arrow keys) to slide it.
- Every board is shuffled with real moves, so it can always be solved.
- Easy: 3×3 with a counter of how far the tiles still have to travel. Hard: classic 4×4. Extreme: 5×5. Nightmare: 4×4 within 200 moves.
- Restart replays this shuffle; choosing a level makes a new one.
