The GraviTrax Skytrax expansion set literally takes your marble runs to new heights. Special connectors and construction elements let you build across multiple levels and guide marbles above the base using cleverly designed bridges. This allows you to create tracks full of drops, acceleration, and smooth transitions between levels.

Included is an instruction booklet with plans of varying difficulty for an easy start, while still giving you freedom for your own ideas. The GraviTrax system is fully compatible with other sets, so you can expand your projects almost without limits. A great choice for kids and adults who want to develop spatial imagination, logic, and an interest in physics through play.

Why choose Skytrax:
- Vertical and horizontal building for maximum variability
- Bridges above the base open up new routes and combinations
- Dynamic marble runs with jumps and sharp speed changes
- Guides for beginners plus free building based on imagination
