The VTech Marble Rush Basketball Set S500 combines the classic structure of a marble run with athletic accuracy. Using two mechanical catapults, you launch the included basketball-themed marbles towards the basketball hoop. The construction system consists of flexibly connectable rails, curves, and pillars that allow for custom track layouts. If a marble misses the hoop or hits the backboard, it rolls back to the base via curved ramps. With compact dimensions of 28.8 x 12.8 x 21.6 cm, the construction fits on standard play tables and playfully trains coordination and dexterity.
