One of my daughters picked up a Perplexus ball as a Christmas gift for her brothers last year. It spanned the ages, working as a gift that suited all kids from ages 6 to 15, and while they occasionally challenged each other about whose turn it was, it proved to be a lot of fun. The goal in maneuvering the tiny ball through the maze is not a novel idea, but it is more challenging in the 3D environment of working this puzzle. Occasional successes made it clear that success could be achieved in solving this puzzle, but there's enough challenge to keep it fun for everyone, including the adults in the house.
