Is this the 8 puzzle or the 15 puzzle?
Both. Choose 3 × 3 for eight numbered tiles, or 4 × 4 for fifteen. Each board has one empty space; the example above uses 3 × 3.
Can every new puzzle be solved?
Yes. New boards are scrambled using legal moves from the completed layout.
Will my puzzle be saved?
Each board size saves its own puzzle, move count, and best in this browser. Switching back resumes that size’s puzzle when storage is available.
