Marble runs have been around for decades, but theyve never been this elegant! Welcome to GraviTrax, an entirely gravity-powered, 100%-modular marble run system for the modern age. There are three key components: hexagonal Height Tiles (provide elevation), Track Tiles, (which rest on Height Tiles and consist of curves, junctions, and intersections for marbles to travel on), and Track Lengths (which hook into and connect Track Tiles). And, of course, colored marbles to race together! Special Track Tiles, such as the Vortex, Launch Pad, or Magnetic Cannon, provide acceleration and flair to the course. Build the track in any configuration desired and let the marbles run wild! Do you want a 3-way race? One long track with crazy twists and turns? Its up to you! Please note the Starter Set is required for all expansion sets.
