GraviTrax goes vertical with the GraviTrax PRO Vertical Starter Kit. Made up of 149 pieces, including some unique components, the set offers everything you need to build your own twist-filled vertical marble runs. Build walls, pillars and balconies and join them to form three-dimensional structures. The elements integrate seamlessly with existing GraviTrax sets, allowing you to create more dynamic marble runs. The pillars have special notches to connect them to transparent walls and create more complex marble circuits. Suspend your circuits in the air thanks to the balconies.

GraviTrax is a modular interactive track system that allows you to create and build your own marble tracks. Based on the concepts of science, technology, engineering and mathematics (STEM) and suitable for boys and girls aged 8 and up, this game encourages experimentation with gravity, magnetism and kinetics in order to propel the marble to at the finish line. Intended for open-ended play, the concept always offers unlimited possibilities for designing different circuits. Maximize your builds and spice them up by adding a variety of expansion sets and accessories.
