Also known as Superplexus
Perplexus, originally released as Superplexus, is a 3-D ball-in-a-maze puzzle or labyrinth game enclosed in a transparent plastic sphere. By twisting and turning it, players try to maneuver a small steel ball through a complex maze along narrow plastic tracks. The maze has many steps (varying across puzzles). The number of steps ranges from 30 in the Perplexus Twist to 225 in the Perplexus 3x3 Rubik's cube Hybrid. Some levels drop the ball into a cup or a small rim to utilize its 3-D nature. Players must complete obstacles varying in difficulty to reach the end.
