Description

From Eric Fuller's description:

The half hour puzzle is a Stewart Coffin classic, and if you don't have a copy in your collection you really should. Although this puzzle is fun and approachable by anyone, it's far from simple. The pieces were deliberately chosen to be as tricky as possible, and there is only one solution. Mr. Coffin has this to say about it:

"The six-piece version of the 3 x 3 x 3 cube will be considered first. For aesthetic reasons, one might prefer that all the pieces be the same size, but this is impossible, so the nearest approximation is to use three four-block pieces and three five-block pieces. It is also desirable that all pieces be non-symmetrical but this is likewise impossible so two of the four-block pieces will have an axis of symmetry. All pieces will of course be dissimilar. Of the several thousand such combinations possible the author tried several that proved to have either multiple solutions or no solution, until finally finding one with a unique solution."

Fit and finish is EXCELLENT on this puzzle. Each is constructed of six different exotic hardwoods, and is fully beveled. These make an excellent gift to puzzlers and non-puzzlers alike. 32 copies made for sale, each signed and dated.
