4. Setup and Assembly
The Quercetti Skyrail League Marble Track is designed for intuitive assembly. The various parts slot together easily, allowing for numerous track configurations. Follow these general steps for construction:

- Assemble Bases and Columns: Attach columns to the bases. The columns come in three sizes, allowing for varying heights and slopes in your track design.
- Connect Tracks: Use the connectors and connection joints to link straight tracks, bent tracks, and half-loops. Ensure all connections are secure to prevent track separation during play.
- Integrate Special Features: Incorporate the starts, arrivals, and obstacles into your design. The two parallel tracks are ideal for creating competitive race layouts.

5. Operating Instructions
Once your Skyrail League Marble Track is fully assembled and stable, you can begin playing. The primary objective is to release marbles and observe their journey through the constructed track.
- Marble Placement: Place one or more of the included marbles at the designated "Start" points of your track. The Skyrail League features two parallel tracks for simultaneous marble release.
- Release Marbles: Release the marbles simultaneously or sequentially, depending on your desired play. Observe how gravity propels them through straight sections, curves, loops, and over obstacles.
- Experimentation: Experiment with different track configurations to understand how changes in height, slope, and track elements affect marble speed and trajectory. This encourages learning about physics principles.
- Competitive Play: Utilize the dual tracks to race marbles against each other, adding a competitive element to the play experience.
