With the GraviTrax interactive track system, you can design and build your own race tracks and experiment with gravity, magnetism and kinetics to propel your gravity sphere to the finish. With a variety of tiles, levels, tracks and features you can control the speed of each gravity sphere.
The open-ended building concept offers endless possibilities to design a different track every time you play. Add speed and flair to your tracks with expansion sets and action accessories. Experience the power of gravity with GraviTrax.
It's very fun and has endless possibilities. You can start with simple tracks and go to more complex and challenging ones. I have spent hours and hours building different tracks with my daughter and the fun hasn't faded even a bit.
