DIAL Cast Metal Puzzle from Hanayama Puzzles of Japan is both a delightful and tricky brain teaser puzzle. It consists of a "Triangular-Shaped" interlocking two-pice cast metal body body and two internal round disks. The object is to remove the 2 internal discs. The second puzzle is to replace/ re-assemble back together. Measures approximately 2 inches tall and .56 inches thick. This is a really fascinating disentanglement brainteaser. You may find yourself turning the center disks around and around for longer than you planned.

DIAL Hanayama Puzzle is a NEW 2017 Design release.

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 !!

Bonus Red Velveteen Drawstring storage pouch. Measures approximately 3 x 4 inches laying flat.

Rated by the manufacturer as a level 5 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. DIAL is part of a series of 60 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.
