Today it is back to my slowly diminishing hoard from Puzzle Master. I do actually plan on eventually getting the entire series of Hanayama puzzles and each order I place with them always includes a few more. This time I am discussing the Cast O'Gear - a really lovely little puzzle designed (as many seem to be) by the hugely talented Oskar van Deventer, whom I was very pleased to meet in the flesh last week, and originally called the Sunflower. In fact, it won an Honorable Mention in the 2001 Puzzle Design Competition at the International Puzzle Party. Just like all the Hanayama puzzles distributed in the West, it comes in the lovely black box with the instructions simply to take it apart and put it back together again. I think it is one of their most attractive designs, being made in the antiqued bronze like finish. It has a nice heft to it and measures 7.9 x 7 x 3.5cm making this a pleasant one to manipulate and allows a decent examination to establish the probable mechanism.
Hanayama have rated this as a level 3 out of 6 which Puzzle Master agrees with as a level 7 (Challenging) on their scale of 5 to 10 and I would agree with this rating. I seem to have come very late to this party as almost everyone else in the world has solved and reviewed it before me (Gabriel, Neil, Oli, Brian and Will have posted at these links). No solution is provided but if you need one then it can be downloaded from here.
