Hanayama Brain Teaser Puzzle Level 6 - Chain

'There’s a whole of wisdom wrapped up in this Oskar Deventer masterpiece. The three pieces can be separated and then joined again in their original form. What’s special about this puzzle is that it can be solved three different ways, depending on which of the three pieces is chosen as the middle piece. Solving this puzzle requires an especially subtle kind of working of the pieces, the kind that often leaves the victim struggling in frustration. Keeping in mind its chainlike behavior and using your feeling to your advantage is the best way to attack this. The key word is 'chain.'

Hanayama Brain Teaser Puzzle Level 6 - Enigma

'America in 1975, the somewhat swirled pieces of this puzzle by Eldon Vaughn must be disjoined and then put back together. I once found a smaller version of this puzzle about twenty years ago in America, but considered it impossible to solve at the time. We have made a new version maintaining the difficulty of the original and licensed it for the Cast Puzzle series. This is without a doubt among the most difficult of all puzzles. The key word is 'twist.' Don’t use too much force… the pieces should just slide apart.'

Besides, the fans that refuse to accept any link of hint are those who make me the happiest! The key word is 'needle.'
