3. Setup and Assembly
The GraviTrax PRO Giant Set is a modular system that allows for endless construction possibilities. Follow these general guidelines for setup:
- Unpack Components: Carefully remove all pieces from the packaging. The set includes a storage box for organization.
- Lay Out Base Plates: Begin by arranging the hexagonal base plates on a flat, stable surface. These form the foundation of your track.
- Build Vertical Structures: Use the height tiles, pillars, and walls to create multi-level structures. These elevate the tracks and allow for complex designs.
- Connect Tracks: Place curve tiles, straight rails, and special action tiles (like the Mixer, Splitter, Loop, etc.) to form pathways for the marbles. Ensure all connections are secure to prevent marbles from falling off the track prematurely.
- Integrate Special Elements: Incorporate kinetic elements such as the Magnetic Cannons, Spinner, Scoop, and Hammer to add dynamic action to your marble run.
- Utilize the App: For guided building, download the official GraviTrax app. It allows you to design tracks digitally and provides step-by-step building instructions for your creations.

4. Operating Instructions
Once your GraviTrax track is assembled, operating it is straightforward:
- Place Marbles: Begin by placing one or more Gravispheres (marbles) at the designated starting point of your track.
- Observe Gravity and Motion: Release the marbles and observe how gravity propels them through the track. Pay attention to how different track elements and kinetic components influence the marbles' speed and direction.
- Experiment and Adjust: The core of GraviTrax play is experimentation. If a marble gets stuck or doesn't follow the intended path, analyze the design and make adjustments. This iterative process enhances problem-solving skills.
- Utilize Action Elements: Activate special action elements like the Magnetic Cannons or the Spinner at the appropriate times to give marbles an extra boost or change their trajectory.

5. Maintenance
Proper care and maintenance will ensure the longevity of your GraviTrax PRO Giant Set:
- Cleaning: Wipe components with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store all components in the provided box or a similar container to prevent loss and damage. Keep the set away from direct sunlight and extreme temperatures.
- Handling: Handle all pieces with care. Avoid bending or forcing connections, as this can cause breakage.
6. Troubleshooting
If you encounter issues with your GraviTrax PRO Giant Set, consider the following troubleshooting steps:
- Marbles Getting Stuck: Check for any misaligned track pieces or blockages. Ensure there is sufficient height difference for gravity to propel the marble. Sometimes, a slight adjustment to a tile's angle can resolve the issue.
- Unstable Structures: Ensure all height tiles and pillars are firmly seated on the base plates and that connections are secure. Distribute weight evenly if building tall structures.
- Marbles Falling Off Track: Verify that all track pieces are correctly connected and that the marbles are not moving too fast for a particular curve or element. Adjust the starting height or path if necessary.
- Kinetic Elements Not Functioning: Ensure any moving parts are free from obstruction and correctly assembled according to the visual instructions provided with the set.
