Quadrilla is the next generation of Marble Runs. It is a system of blocks, tracks and accessory pieces that allow the energy of a Marble to travel in a make-your-own path. Beautiful wooden tracks and a rainbow of coloured blocks, each with a different function, are the starting point for endless contraptions for Marbles to drop to a new level, go right or left, swirl in a funnel, or pour out of a teeter totter.
Included is: A 50 Piece Wooden Marble Run Set
5 metal sound tones to put into the blocks or on the rails Tones G, A, B, C, D
20 coloured marbles in a bag
