Unhinged
[019275068264]

Unhinged is a new brainteaser from ThinkFun. The goal is to flip, fold and rotate the hinged hexagons to solve the 40 different puzzles that come with the brainteaser. There are a couple of things that I really like about Unhinged. First there are no parts to lose. The brainteaser is all one item. Second the challenges start out easy and get increasingly harder as you work through the challenge book.
