GraviTrax is an interactive marble run system made by Ravensburger. Instead of just letting marbles roll down tracks, GraviTrax combines STEM learning (science, technology, engineering, math) with creative play by letting you design and build your own tracks — then add special action elements that use gravity, magnetism, and kinetics to create unique runs.
GraviTrax Micro is the portable marble run system from GraviTrax that allows you to create tracks almost anywhere, whether at home, on the go, or while traveling
GraviTrax Junior is a younger version of GraviTrax, designed for kids around 3 to 7 years old. It keeps the same basic idea — building marble runs — but everything is simpler, chunkier, and themed for imaginative play instead of abstract physics.
GraviTrax products are grouped in several product lines. All the main product lines (i.e. GraviTrax CORE, GraviTrax PRO, GraviTrax POWER and GraviTrax SkyTrax) are compatible and the parts can be combined.
GraviTrax Junior is a separate product line aimed at younger children (3-7) which can still be combined with main GraviTrax line products using the 27532 Adapter-Set.
GraviTrax Micro is a compact product line designed to bring the GraviTrax building experience into a smaller format. It features its own specially designed parts and components and is not compatible with other GraviTrax product lines.
Gravitrax products are grouped and marketed as several categories: Starter Sets, Extensions, Elements, etc. Note that before 2023, sets used also terms Expansions, both for Element and Extension sets.
