Sliding Puzzle 3×3

Controls Goal: put the shuffled number tiles in order from 1 (the last cell stays empty). Your score is the time taken — shorter is higher; the move count is just for reference. Controls: click or tap a tile to slide it toward the gap — if it is in the same row or column as the gap, every tile in between slides together and counts as one move. On a keyboard use the arrow keys or WASD; on touch, swipe on the board. Both move the tile in that direction (↑ lifts the tile below the gap). Tab only stops on tiles you can move. The clock starts at your first move and there is no pause. Tips: solve the top row first, then work row by row; for the last two rows, finish column by column. Tiles in their right place turn green. Every shuffle is solvable.
