Cast Enigma Puzzle
My colleague Scott recently introduced me to the Hanayama puzzle collection. The Cast Enigma is ranked as one the hardest metal puzzles in the world. It looks so simple and yet so impossible. I ordered one from Canada as I couldn't find any store or online store in the US that carried it! I was hoping that it would keep me busy on a long flight. But I was able to solve it last night in my first uninterrupted attempt. It is very clever and I really enjoyed it. Putting it back together was a lot more difficult.
