Let the ball go crazy! Build your spiral individually and connect different heights dizzily. Combine the spiral with the GraviTrax starter set and bring even more action to your route. What new possibilities does the spiral open up on your train? 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 ball to the finish. With a variety of tiles, levels, tracks and features, you can control the speed of each ball. The open-ended building concept offers endless possibilities to design a different track every time you play. Add flair and speed to your tracks with expansion sets and action accessories. Experience the power of gravity with GraviTrax.
