About 15 Puzzle
The 15 Puzzle dates back to the 1870s and still tests patience and planning. Fifteen numbered tiles share a frame with one empty space, and you slide tiles into the gap until the numbers run in order.
How to play
- Tap a tile next to the gap to slide it.
- On a keyboard, the arrow keys move tiles into the gap.
- Arrange the tiles from 1 to 15.
Tips
- Solve the top row first, then the second row.
- Finish the last two rows column by column.
- Fewer moves and less time mean a higher score.
