3. Setup Instructions
The MEGA BLOKS Build & Race Rig is designed for easy assembly and reconfiguration. Follow these steps to set up your play:
- Assemble the Race Cars: Each race car consists of a chassis with wheels and a colorful car body. Snap the car bodies onto the chassis to complete the two race cars. The car bodies are interchangeable, allowing for mix-and-match customization.
- Prepare the Rig: The big rig truck comes in two main sections (red cab and blue trailer). These sections can be connected or separated depending on the desired play configuration.
- Attach Ramps: The yellow ramp pieces can be attached to various points on the rig and trailer to create different race tracks or loading/unloading ramps. Experiment with different block placements to create varied ramp heights and angles.
- Integrate Building Blocks: Use the included large building blocks to enhance the rig, create obstacles, or build additional structures around the racetrack. The blocks can be placed on the studs located on the truck and trailer.
