Sliding Puzzle — Classic 15-Puzzle Online Free
Play the classic sliding puzzle (15-puzzle) free in your browser. Solve 3×3, 4×4, or 5×5 grids in the fewest moves and the fastest time.
The sliding puzzle — also known as the 15-puzzle — is a timeless brain teaser where you slide numbered tiles around a square grid to put them back in order. Our online version runs entirely in your browser with three difficulty levels: an approachable 3×3 (8-puzzle), the classic 4×4 with 15 tiles, and a brain-bending 5×5 with 24 tiles. No downloads, no accounts, and no ads getting in the way of your solve.
Every shuffle is guaranteed solvable because the board is scrambled by performing random legal moves from the solved state. Track your progress with the live move counter and timer, then try to beat your own personal best. The puzzle works equally well with mouse, touch, or arrow keys — perfect for a quick mental workout on desktop or mobile.
