Perplexus 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 100 barriers and provides a three dimensional experience. Players must work with gravity and carefully shift, flip, and twist the sphere to guide the marble. It is a great toy for children to exercise their motor and dexterity skills, as well as improve their hand-eye coordination.
