15 Puzzle
Slide the numbered tiles into order.
How to play the 15 Puzzle
Move a numbered tile into the empty space. Arrange 1 through 15 from left to right and top to bottom, leaving the final square empty.
Rules
- Only a tile next to the empty square can move.
- Arrow keys also work on desktop.
- Refreshing starts a fresh session.
Tips
Solve the top rows first and avoid disturbing completed sections. Work in small cycles near the empty square instead of moving tiles randomly.
