Object: Remove Shuttle; Complex Level of Difficulty; Dimensions: 10'' Long
This design is the one of the oldest known puzzles in the world. Based on the traditional Chinese Ring Puzzle (9 rings). More mathematical than the other designs. The solution is finding the correct sequence of two basic moves that are repeated, resulting in a 43-step solution. A classic!
Each puzzle is mechanical in nature: you do not need to use any force or tricks. Puzzles are solved when the object piece is removed. Every puzzle can be considered two puzzles in one, because the solution is not truly mastered until the object piece is returned to its starting point.
