A more difficult variant of the classic tile-sliding puzzle.

• "fire":"left_mouse"
• "jump":"na"
• "movement":"na"

Use logic, planning and a little short term memory to arrange the tiles into the correct positions. Unlike the traditional sliding-tile puzzle in which the tiles are marked with a number or a section of an image from which you can deduce their correct positions, in this variant, the tiles will be marked with relevant chess pieces as clues to their correct positions.
