The shuffled board is ready when the page opens. Tap a tile directly beside the gap to slide it.
Arrange the rows as 1 2 3, then 4 5 6, then 7 8 and the empty space.
Use Undo move to reverse your last slide. Undo counts as a move, too.
Finish the board to save your move count, or choose New puzzle for another starting layout.
Sliding Puzzle turns a familiar eight-tile board into a short planning break. Our starting layouts have shortest solutions between 12 and 16 moves, avoiding both nearly finished boards and long random scrambles. There is no countdown and no limit on attempts. Green tiles mark positions that currently match the goal; they are still movable.
Your result is the number of moves used to finish a board; lower is better. Each slide and each undo adds one. Restarting an unfinished board saves nothing. Starting layouts differ, so personal bests are not comparisons of equal puzzles.
More about your scores →If the bottom row reads 7, gap, 8 and the other two rows are already correct, select 8. It slides left into the gap, leaving the empty space in the bottom-right corner and completing the board.
A tile can move only into the empty square. Before moving it, trace where you need the gap next. A short loop often helps bring a tile around a corner.
Green means the tile is currently in its target position. It is not locked. Finish the top row, then solve the lower rows together rather than refusing to disturb any correct tile.
Place the top row first, then work with the remaining two rows.
Think about where the gap will end up after each slide.
Sometimes a tile must temporarily leave its correct position to let another through.
Results describe this game session. They are not IQ scores, diagnoses or clinical assessments.
No. Every starting board is reachable from the solved layout and has a shortest solution of 12–16 moves.
No. Only a tile sharing an edge with the empty square can move. An invalid tap does not add a move.
No. It reverses the board change but adds one move to the total. This keeps the result a count of all slides, including steps you reverse.
The highlight is only a guide. You may need to move that tile temporarily to bring another tile into place.
