Give your marble run a level-changing twist with the GraviTrax® PRO Turntable!

GraviTrax is the all-new STEM track system from Ravensburger®! Use your imagination to build superb tracks and set the Gravity Spheres rolling!

GraviTrax is a modular, electronic-free, interactive track system where you can design and build your own marble runs. This STEM toy for kids encourages experimenting with gravity, magnetism and kinetics to propel your marble to the finish. Designed with open play in mind, the concept offers endless possibilities to design a different track every time you play.

Expand your builds and add some action with a variety of expansion sets and accessories.

Gain control over the direction of your marbles! As your marble falls into the turntable, it will change direction, and make the turntable spin. The Turntable allows for even more track variation and more control over the direction your marble. Combined with a Starter Set, even more challenging tracks can be created. How many times can you make the Turntable rotate? This set includes 1x turntable.
