Perplexus is a 3-D ball-in-a-maze puzzle or labyrinth game enclosed in a transparent plastic sphere. By twisting and turning the sphere, players attempt to maneuver a small steel ball through an intricate maze composed of a number of steps (varying in each puzzle) along narrow plastic tracks. The number of steps ranges from 30 in the Perplexus Twist to 225 in the Perplexus 3x3 Rubik's cube Hybrid. Some of the steps involve dropping the ball into a cup or through a small rim to take advantage of its three-dimensional nature. There are obstacles of varying difficulty that must be navigated in order to reach the end.
