Puzzle One is an extremely difficult casual permutation puzzle sandbox. Turn the handles to rearrange the marbles into their original state. This game is a 2D analogue of the popular 3D twisty puzzle genre, and will appeal to people interested in twisty puzzles and speed solving.
This game is very, very challenging.
Puzzle One is a sandbox. It runs like an application, and has no form of progression. All puzzles are immediately available. There is no specific goal. Figure out a difficult puzzle, or try to beat your best time on one you've mastered.
