I've posted in the past about the various maze games in this family including the Perplexus, Perplexus Epic, and the giant version of the the Superplexus (selling for a whopping $30,000). Here's another in this popular series of 3D maze games, The Perplexus Twist. As with the others, it is a maze game where players must maneuver a small marble around challenging barriers inside a transparent sphere.
