DUET Hanayama Cast Metal Brain Teaser Puzzle
DUET Cast Metal Puzzle from Hanayama Puzzles of Japan (and Be Puzzled here in the USA) is a delightful and tricky brain teaser puzzle. It consists of a chrome-colored grid and a gold-colored metal ring with slit.The object is to remove the ring from the grid   The puzzles works somewhat similar to a 3-D maze in that there are numerous dead ends.    The grid has strategically placed groves on both sides.   This allows the small space in the ring to move about the grid and eventually off the grid.  The ring comes apart into two pieces (slices like a bagel).   Grid measures approximately 2.5 inches.This is a really fascinating disentanglement brainteaser. You may find yourself going around and around in circles for longer than you planned. You may solve the puzzle and not know actually how you arrived.  Replacing the ring to the bottom rounded corner of the grid is equally as challengingRated by the manufacturer as a level 5 difficulty (on a scale of 1 to 6; where 6 is the most challenging.)  Number on the packaging indicates the level of difficulty. Your own experience could vary substantially.   DUET is part of a series of 45 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.
