PLEASE NOTE: GraviTrax® Starter Set is required and available separately.

GraviTrax^® is a modular, electronic-free interactive track system where you can design and build your own marble runs. This STEM toy for kids encourages experimenting with gravity, magnetism and kinetics to propel your marble to the finish. Designed with open play in mind, the concept offers endless possibilities to design a different track every time you play.

Expand your builds and add some action with a variety of expansion sets and accessories.

Add stealth and surprise with 18 new elements in the GraviTrax® Expansion: Tunnels set. Straight, curved and vertical tunnels hide the marbles as they zip around the tracks. Will you be able to keep your eye on the marble as it rolls through the Tunnels? Test the Bernoulli and O-tracks to see how much speed you can generate and where you can drop a marble to a level below.
