Marble Runs GraviTrax The Game

Design and build your own marble runs and experiment with gravity, magnetism, and kinetics to propel your marble to the finish, with the GraviTrax Flextube track system. The FlexTube, allows you to easily connect between the different heights in your tracks.

What comes up, must come down and with this extension you can easily change the direction of your marbles. The FlexTube can easily be adapted for 60-degree angles, u-shapes and s-shapes. Combined with a Starter Set, the speed in your track can also be controlled. Additional height stones are included in this extension so you can build even higher. (Note: only playable with the starter set!)
