15 Puzzle High Scores

Scoring

• Only a tile next to the gap can move, and it moves into the gap. Clicking a tile further along the same row or column slides the whole line of tiles between it and the gap in one go.
• The puzzle is solved when the tiles are in order with the gap last.
• Every shuffle here is solvable — half of all possible arrangements are not, and we never deal one of those. Shuffles are also never nearly solved already.
• The clock starts on your first move and stops the moment the last tile lands. Moves count tiles moved, so sliding a line of three counts as three.
• Best times and fewest moves are kept separately for each board size.
