The Hanayama Cast Enigma puzzle is a real head-scratcher. Patented in America in 1975, the somewhat swirled pieces of this puzzle by Eldon Vaughn must be disjoined and then put back together. Sounds easy? It's not really. Hanayama Cast Enigma is without a doubt among the most difficult of all puzzles, and we do mean all.
The key word to Hanayama Cast Enigma is "Twist". Don't use too much force...the pieces should just slide apart. At a crazy 6/6 difficulty, Enigma won't make it easy to figure out where.
