Setup and Assembly
The GraviTrax system is designed for flexible and creative assembly. There are no rigid step-by-step instructions for a single track, but rather guidelines and blueprints to inspire your creations. The included instruction and blueprint book provides 6 assembly instructions with varying difficulty levels (simple, medium, challenging) to help you get started.
Basic Assembly Principles:
- Plan Your Track: Before building, consider the path your marble will take. Use the hexagonal base plates as your foundation.
- Build Upwards: Use height stones to create elevation changes. These can be stacked to achieve desired heights.
- Connect with Rails and Curves: Use the various rail lengths and curves to connect different sections of your track. Ensure connections are secure.
- Integrate Action Elements:
- Spiral: The spiral allows marbles to descend quickly while maintaining momentum. Its height can be adjusted by adding or removing height stones underneath.
- Trampoline: Position the trampoline where you want marbles to bounce. Experiment with placement to achieve different bounce heights and trajectories.
- Test and Adjust: After building a section or the entire track, test it with a marble. Observe where the marble loses momentum or goes off track and make adjustments.

Remember, all GraviTrax products from the Core, PRO, and Power lines are combinable, allowing for even more complex and expansive track designs.
Operating Instructions
Operating your GraviTrax marble run is straightforward once assembled. The primary goal is to guide the marbles from a starting point to a target using gravity and the various track elements.
Playing with GraviTrax:
- Place a Marble: Select one of the included marbles (blue, red, or green) and place it at the designated starting point of your track.
- Release the Marble: Gently release the marble and observe its journey through the track.
- Observe and Learn: Pay attention to how the marble interacts with different elements. Notice how the spiral changes its descent, or how the trampoline affects its trajectory. This encourages an understanding of kinetic energy, gravity, and momentum.
- Experiment: The true fun of GraviTrax lies in experimentation. Try different starting points, adjust the height of elements, or reconfigure sections of your track to achieve new results.
The set includes a "balls and spinner" element which can be used to launch multiple balls or add an initial spin to the marble, enhancing the play experience.
Care and Maintenance
To ensure the longevity of your GraviTrax Action-Set Twist and maintain optimal performance, follow these simple care instructions:
- Cleaning: Wipe components with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure parts are completely dry before storage. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store all components in their original packaging or a suitable container to prevent loss or damage. Keep the set in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Handle all parts with care. Avoid dropping or stepping on components, as this can cause breakage or deformation.
- Marbles: The included marbles are designed for the GraviTrax system. Avoid using marbles of significantly different sizes or weights, as this may affect track performance or damage components.
Troubleshooting
If you encounter issues with your GraviTrax track, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Marble stops or slows down excessively. | Insufficient height difference; friction; misaligned parts. | Increase the starting height or the height difference along the track. Ensure all connections are smooth and aligned. Check for any debris on the track. |
| Marble falls off the track. | Too much speed; sharp turns; unstable base. | Reduce initial height or add elements to slow the marble down before turns. Ensure curves are properly supported. Verify the track is on a flat, stable surface. |
| Action element (e.g., Trampoline, Spiral) not working as expected. | Incorrect placement; insufficient marble speed/momentum. | Refer to the blueprint book for optimal placement of action elements. Adjust the track leading into the element to ensure the marble has enough speed or is approaching from the correct angle. |
| Missing or damaged parts. | Packaging error; accidental loss/damage. | Carefully check all packaging materials. If parts are genuinely missing or damaged upon opening, contact Ravensburger customer support. |
