About 15 Puzzle

The 15 Puzzle is one of the oldest sliding puzzles in the world, and this Lizely version keeps it exactly as sharp as the original. You get a 4x4 frame with fifteen numbered tiles and one empty space; slide tiles with your arrow keys or a click until the numbers read 1 through 15 in order. Every board this game deals is checked for mathematical solvability (an odd-permutation board can never be solved, so Lizely simply never deals one). Your best result is counted in moves, not time, so the game rewards planning over frantic clicking: solve the top row first, then the left column, and repeat on the shrinking board that remains. It runs entirely in your browser — nothing is uploaded, nothing is installed, and the double-Esc boss key instantly swaps the board for a spreadsheet when someone walks past your desk.

Frequently asked questions

Is this 15 puzzle free to play?
Yes. The Lizely 15 puzzle is completely free, with no download, no sign-up, and no limits on how many rounds you play.
Is every shuffle actually solvable?
Yes. Half of all random tile arrangements are mathematically unsolvable, so the game checks the permutation parity of every shuffle and only deals solvable boards.
What are the keyboard controls?
Use the arrow keys to slide tiles into the empty space, press Restart to reshuffle, and press Esc twice for the boss key screen.
