GraviTrax Starter-Set Speed

Playtime is looking marble-ous and far-out! Kiddos have everything they need to construct their very own action-packed track system, including base plates, two transparent levels, six marbles, large and small height tiles, curves, tracks, magnetic cannon and so much more. Just open the box and explore nine different ready-to-build systems that combine gravity, magnetism, and kinetics to propel your marble to the finish.

From Ravensburger, for ages 8 yrs-teen.
