This is a cool 3-dimensional maze that is easy to get started and hard to finish. You need to steer a small metal ball along an ingenious obstacle course by rotating the clear plastic globe. There are 100 stations along the way, including some difficult topsy-turvy turns. All ages can get into it. We’ve found the puzzle to be extremely addictive to anyone who gets started. Because it’s like a 3D video game without the electronics, the very physical nature of playing — turning it this way and that — is very satisfying. In addition, the maze is like a sculpture, the design of the route is geekily brilliant, and the elegance of the eternal return of the steel ball within the sphere is a stroke of genius. Perplexus has the glow of a work of art. It makes me happy just to pick it up.
