GraviTrax is the all new innovative marble run track system from Ravensburger, the German Jigsaw Puzzle Giant for over a century. GraviTrax is created based on STEM ideology (Science, Technology, Engineering and Maths), and it is an ideal STEM system to teach kids about physics concepts such as gravity, magnetism, kinetic energy, and to promote their creativity and problem solving skills, and most importantly fun.

GraviTrax is derived from the combination of two words, "Gravity" and "Tracks". Its track system is specially designed and crafted for the magnetic gravity balls to make sure minimum fiction generated during play, which allows the gravity balls to reserve more kinetic energy to complete various upcoming mechanisms, and to roll to their furthest distance possible. The idea of GraviTrax is to let kids experience the power of gravity. Kids can use their own imagination to build superb tracks and set the gravity spheres rolling.

Surprisingly, there is no limit set to GraviTrax's construction, the whole system can be extended indefinitely with extra track packs and add-ons. ith a variety of tiles, levels, tracks and features you can control the speed of each gravity sphere. The open-ended building concept offers endless possibilities to design a different track every time you play. Kids can stretch their imagination as much as they like, freestyling with their own track design.

Hit a snag? Each set includes blueprints and tasks instructions to help players to get started in the world of GraviTrax. If you are looking to build a massive project, Ravensburger also created a free "GraviTrax App" in both Android and IOS mobile platforms to assist you with more sophiscated detail design.

Recommended age of GraviTrax player: 8 years+.
