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. WARNING: CHOKING HAZARD - Small parts. Not for children under 4 years.

Quadrilla's versatile design allows the child to determine the Marble's path and the options are endless. Simple 2 or 3 level switches or complex multi-level, multi-direction layouts are possible depending on the builder's understanding of the function of each piece.
