15-Puzzle

Pro Canvas Puzzle

The classic sliding tile puzzle at three sizes. Slide numbered tiles into the gap until they are back in order. Tiles already in their final position turn green. Every shuffle is tested with the inversion-parity rule before it is dealt, so no layout is ever impossible, and your lowest move count is kept per size.

Controls

Mouse: Click a tile next to the gap to slide it. Touch: Tap a tile next to the gap. Keyboard: Arrow keys slide a tile into the gap. Use the buttons to shuffle, reset, or change the board size.
