What It IsThe design and play possibilities are practically endless with the Quadrilla Twist & Rail Set. Quadrilla is a system of blocks, tracks, and accessory pieces that allow the energy of a marble to travel down a path that the player creates. Wood tracks and a rainbow of colored blocks, each with a different function, are the starting point for constructions in which marbles drop to a new level, go right or left, swirl in a funnel, or pour out of a teeter totter. This versatility in creating and building allows a child to determine the marble's path and try out many different configurations. The process of building is as much fun as the process of playing. Quadrilla Twist & Rail Set includes 97 pieces and 50 marbles.
Other sets available include seven Core sets, four Extension sets, nine Expansion sets, and five Fun sets, each sold separately.
