Quadrilla

Quadrilla marble runs are made of a system of wooden colour-coded blocks, rails and accessory pieces that allows the child to determine the marble's path. Each different coloured block has a different function - some are switches, some make the marble turn through 90 degrees, some let it pass straight through. The pieces fit together easily and all the sets can be combined. Making and playing with these colourful sets can provide hours of fun!
