Two people compete to see who can be the first to get all 10 of their marbles down the track and into the winner's box at the bottom. Each player starts by dropping marbles, one at a time, in the highest ramp. If you drop the marbles too quickly they will collide and slow down or even "jump the track." You must get your timing just right to beat your opponent. The competition is fast and intense. Adults like this game as much as the children. All patterns drawn FULL SIZE. Measures approximately 34"H. Order two #3174 Marble Derby Decals and two packages of 10 (20 total) #3129 Large 1" Game Marbles separately.
