This colossal version of our best-selling classic toy builds towers and tracks that twist, turn and spin your marbles on an entirely new scale. Track splitters send marbles down alternating paths. The jump slide launches marbles through the air and into the waiting catcher with unbelievable accuracy. Funnels, wheels and rickety rails create fantastic marble action at every turn. Assembly is easy: simply slide the pieces together. Featuring 215 parts plus 40 marbles, this Mega set is fully compatible with our original Marble Run. This deluxe set adds a Motorized Marble Elevator to your creation to really keep things rolling! Motor uses two AA batteries (sold separately).
