Perplexus Maze Game

I was in Target recently and spotted this fun game- the Perplexus Maze Game.  It looked pretty fun and I started playing with it in the store.  That evening I came online and found all these reviews for them.  I think this is going to be all the rage this Christmas.  If you head here you can enter the giveaway for one.  Who wouldn't want one of these? 

PERPLEXUS is a maze game where players 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 challenging tracks with 100 barriers providing a frustrating 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.
