Can you take it apart? Can you assemble it again?
This brain teaser is a great challenge for anyone who enjoys mechanical style take-apart challenges. Recommended for ages 12 to 105 years. Some bright 8 to 11 years olds may also find this a fascinating challenge. Solving the puzzle is somewhat similar to solving a paper maze with pencil. There small nubs on the outer ring. This allows it to move along the maze paths. You will probably encounter numerous dead-ends.
