Fifteen: 15 Puzzle

Slide fifteen numbered tiles into order on a four-by-four board. Choose a difficulty or tackle the daily puzzle, with Undo and local progress.

Controls

Click or tap a tile next to the gap. Arrow keys slide a tile into the gap; Z undoes a move and P pauses.

Put the numbers in order

Move a tile next to the empty space into that space. Arrange the numbers from 1 to 15 in reading order, leaving the empty space at the bottom right. Only tiles adjacent to the gap can move.

Modes and controls

Choose Easy, Classic or Expert, or use Daily Challenge. Click or tap an adjacent tile; arrow keys slide a tile into the gap. Undo reverses a recorded move, while Show goal shows the target arrangement. The game has its own Pause control.
