Game description from the publisher:
In Maze Racers, you use the enclosed magnetic walls and a good dose of creativity to build the most wicked maze possible that will leave your opponent scrambling to find his way out. The game is also a race against time as your opponent is building his own devilish contraption. When the time is up, both sides switch their maze boards and steer a ball through the opponent’s maze as quickly as they can. Be the fastest in two out of three rounds to claim victory!
