The ZBall is a special marble very easy to control and that can stop in inclines. Players have to flick their way through the obstacles as fast as possible to win the race, and they can jump over their opponent’s car to pass them. No batteries are required, and hundreds of tracks can be designed for over 13' of fun. Kids can also use the track and cars separately to play by themselves. "This is the only race track on the market that can be played on with the whole family and doesn't need electricity!" Cedric Arnould, vice president of CEPIA Games, told TDmonthly.
