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. Control the speed of each gravity sphere with a variety of tiles, levels, tracks, and features. The open-ended building concept offers endless possibilities to design a different track every time you play.
