About the game

A browser adaptation by Zarocer.

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.

Make room for the tile you need

The gap is your working space. Move it beside the tile you want to relocate, then use a small cycle of neighboring tiles to bring that tile closer to its target. Dragging attention from one misplaced number to another makes it easy to undo earlier progress.

Build the upper row while keeping the unsolved region available for maneuvering. The final two tiles of a row need planning together; fixing one too early can trap the other below it. When only two rows remain, work in pairs of columns rather than trying to lock every bottom tile independently. Show goal lets you check the intended arrangement without guessing.

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.
