From the developer:
PerPuzzle lets you play permutation puzzles. A permutation puzzle presents a tableau of tokens which may be scrambled up. The challenge is to restore the scrambled tableau to its starting arrangement using a set of allowed moves. At present four puzzles are available: the classic Fifteen Puzzle, the Sixteen Puzzle, The Mad Orbit Poser, and the WrapSlide Puzzle.
