Last refreshed Sep 28, 2026 · Based on the Amazon listing and published specifications, not hands-on testing.
A small add-on for owners of a GraviTrax set who want more track variety. It is an extension, not a standalone marble run, so a starter set is needed to build anything.

Overview
Adding color swap, volcano, dipper and red elements to an existing GraviTrax layout is the job of this Ravensburger Triplex extension, which also brings balls to run through it. Instructions are included.
It widens what an existing track can do without replacing it, and the pieces can be combined across the system's lines. The limitation is that nothing can be built from this box alone.
Who it's for
Builders of the stated age who already own a starter set and like testing how balls roll. Newcomers who want a self-contained set should begin with a starter set.
Pros and cons
- Color swap, volcano and dipper elements
- Three balls included
- Combines across GraviTrax lines
- Needs a starter set to use
- Element counts not itemized
- Not a standalone marble run
Performance notes
Each element changes how a ball behaves as it rolls under gravity, so the layout decides the result and the description mentions no motor or battery. The listing names color swap, volcano and dipper elements without explaining each action, so the instructions are where the details live.
