Sliding Puzzle

Goal: Arrange the numbered tiles in order from 1 in the top-left, ascending left-to-right and top-to-bottom, with the empty space in the bottom-right corner.

How to move: Click any tile that is directly adjacent to the empty space (up, down, left, or right) to slide it into the gap. Only tiles next to the empty space can be moved.

Difficulty: Choose between a 3x3 grid (8 tiles), 4x4 grid (15 tiles – the classic "15 puzzle"), or 5x5 grid (24 tiles) for an extra challenge.

Moves & Timer: Your move count and elapsed time are tracked above the grid. Try to solve the puzzle in as few moves as possible!

Undo: Click Undo to reverse your last move. You can undo as many times as you like.
