Our Basic Set of 49 pieces includes blocks, rails, and a twist. The Xcellerator Set has 136 pieces, including a twist and 10 accelerators. The 198-piece Cyclone Set is Quadrilla's largest marble run set, with two spiral funnels, twelve curved rails, ten accelerators, and a large assortment of building blocks. All sets include 50 marbles and terrific instruction books.
