Quadrilla The Ultimate

Hape

The largest set in the Quadrilla marble-run range. Children build towering tracks, then send marbles racing down through spiralling funnels and speed-boosting accelerators, experimenting with layouts to change the run. Great for engineering thinking, planning and cause-and-effect, along with fine motor skills. Includes two funnels, twelve curved rails and ten accelerators among the building parts. Best from around 4 years.
