How to Play the Sliding Puzzle Game
- Choose your grid size: the 8-puzzle or the more challenging 15-puzzle.
- The board shuffles automatically, leaving one empty space among the numbered tiles.
- Click any tile next to the empty space to slide it into that gap.
- Plan a few moves ahead, since sliding one tile changes which tiles can move next.
- Keep sliding tiles, one move at a time, to arrange all the numbers back into order.
- Watch your move counter and timer, and try a new shuffle to beat your best result.
Who Uses This Tool: puzzle enthusiasts looking for a classic logic challenge, students practicing sequencing and spatial reasoning, and anyone who grew up with the physical sliding tile toy and wants a digital version with a timer to chase. Some players also use the 15-puzzle specifically to practice the kind of forward-planning skills that carry over to other logic games.

Frequently asked questions
How do I move a tile?
Click any tile that's directly next to the empty space (above, below, left, or right) and it slides into that gap. Keep sliding tiles until the numbers read in order.
How do levels and the timer work?
The game is endless - every couple of levels the grid grows a size (starting at 3x3, up to a 6x6 cap), and the time limit keeps shrinking. Solve the puzzle before time runs out to advance; run out of time and the game ends there.
Is every shuffled puzzle actually solvable?
Yes - each shuffle is generated by making a long sequence of valid random slides from the solved state, which guarantees it can always be solved back to the original order.
