CAKE Hanayama Puzzle is a NEW 2017 Design.
Recommended for ages 12 to 105 years. A few bright children between 8 to 11 years may also enjoy, provided they understand that NO force is used to solve. Forcing pieces may damage the puzzle !!
Rated by the manufacturer as a level 4 difficulty (on a scale of 1 to 6 where 6 is the most challenging.) Difficulty level shown on the packaging. Your own experience could vary substantially. CAKE is part of a series of 55 plus very interesting and mentally provocative metal brain teasers from the Hanayama Puzzle Company. Some serious puzzlers refer to these as "disentanglement-style puzzles" as they involve taking something apart and then re-assembling. Re-assembly can also be a puzzle and may be equally as tricky.
Reminder. NO FORCE is ever required to solve the puzzle. Just a series of clever moves.
