 It is a game in which players lift a ball by concentrating and move it through a maze.The concentration levels are measured by a headset using NeuroSky technology which wirelessly interfaces with a platform that floats the ball through the use of a fan which was moved around the course in a circle by a dial; (this platform was based on a previous Mattel toy, the “Harry Potter Sorcerer's Stone Electronic Levitating Challenge Board Game”).The MindFlex allowed the player to modify the course by sticking plastic obstacles in peg holes at different locations and was preprogrammed with 5 games as well as multiplayer options.The game was a “phenomenal success” and one of the best sellers of the Christmas season; in fact, Mattel sold out its entire stock five weeks after launch.
