Frequently Asked Questions
What do I need to start building with GraviTrax?
You need a starter set like the GraviTrax Energy Action Set, which includes base plates, tracks, marbles, and action elements to build complete courses. Individual expansion elements like the Zipline or Splitter add new mechanics but require a starter set to use.
What is the difference between GraviTrax and GraviTrax Pro?
Standard GraviTrax elements work on flat-plane track layouts. GraviTrax Pro pieces like the Splitter add vertical building — pillars, walls, and multi-level structures — so tracks can go up and over each other. Pro elements are compatible with all standard GraviTrax sets.
What age is GraviTrax for?
GraviTrax is designed for ages 8 and up. The building and engineering concepts scale with the builder — younger kids can follow the included challenge cards, while older kids and adults design freeform layouts with increasingly complex physics interactions.
