How to play Sliding Puzzle
Play a free 15 Sliding Puzzle online. Slide numbered tiles with touch, mouse, or arrow keys and restore the classic 4x4 grid.
Objective, rules, and result
A numbered tile can move only into the adjacent blank space. Restore the grid to ascending order from 1 through 15 with the empty space in the final position; moves are counted.
How to play
- Select a numbered tile directly beside the empty space.
- Keep sliding tiles while planning how rows and columns fit together.
- Arrange the numbers from 1 through 15 with the blank at the end.
Controls
Keyboard and mouse: Click a tile beside the empty space or use arrows.
Touch: Tap a tile beside the empty space.
Shortcuts: U: undo; H: hint; R: restart.
Strategies to try
- Solve the top row first, then preserve it while arranging the next row.
- Move the blank in small loops to reposition a target tile without disturbing completed areas.
Device and accessibility notes
Click or tap an adjacent tile, or use Arrow keys; U undoes, H hints, and R restarts. Every tile has a printed number, so colour is decorative.
