Fascinating physics inspires hours of play! Press one of the the two buttons to launch and watch as the gradually widening track propels the ball forward. Send the blue ball rolling down the long zig-zaggy track. Send the orange ball swirling along the winding curvy track. Or, launch them both at the same time to see which one's the fastest! Exploration and experimentation are on a roll the moment kids get their hands on the RollAgain Maze.
