For ages 6+ years. For ages 6+ years. Perplexus is a maze game where players maneuver a small marble around barriers inside a transparent sphere. Unlike traditional flat-surface mazes that are composed of one path, Perplexus houses various challenging tracks with 100 barriers providing a challenging three-dimensional experience. Players select the track they would like to attempt and must work with gravity to carefully shift, flip and twist the sphere to guide the marble. Players can race each other or the clock.
