Quartet Cast Puzzle - Very Hard Puzzle
Not for the faint of heart, The Quartet Puzzle is a deviously tricky disentanglement puzzle, named after the number of pieces involved. There are 4 pieces total that form the quartet, and they must be twisted, turned, finagled, and jostled in the perfect way to untangle the dark, metal pieces. The bond that these pieces form is truly difficult to unravel. For added fun, there are actually two approaches to this puzzle and we challenge you to try out both of them! This puzzle is the perfect gift for people who love construction and engineering and an added bonus for those who love to fidget.
