Perplexus Puzzle Ball Perplexus is a maze game where players must maneuver a small marble around challenging barriers inside a transparent sphere. Unlike traditional flat-surface mazes that are composed of one path, Perplexus houses various exhilarating tracks with many barriers and provides a three dimensional experience. Players select which track they would like to attempt, and then must work with gravity and carefully shift, flip, and twist the sphere to guide the marble. Players can race each other or the clock. On top of being entertaining, Perplexus is also an educational toy, and assists in child development.
