Cast Keyring: Hanayama Mechanical Puzzle of the week Review
Click here for the solution. Cast Keyring comes from Oskar van Deventer. There are 2 pieces which are almost identical. Or maybe they are identical. I'm not sure now. It's actually a maze disentanglement puzzle. It's very cool and clever and I've solved it numerous times over the years. My advice: buy 3 copies. 1 for yourself, another for a niece or nephew, another for an office grab-bag Christmas party.
