Learn how to build and optimize the Mega Loop track from the Combo: Mega Loop set. Step-by-step assembly, common mistakes, and tips for high-speed loop action.

Quick answer

Start by assembling the Super Speed Playset, then attach the Loop Add-On Kit to create a high-speed run that launches cars into one satisfying loop. This guide walks you through each step and common pitfalls.

Why the Combo: Mega Loop is a good starting point

The set combines two ROADWORKS™ playsets into one ready-to-play layout, so you don't need to buy extra pieces to get a working loop. It's compatible with CANDYCAR®, TOONS™, and 1:64 scale cars, giving you flexibility if you already own other cars.

One trade-off: the included Hachigo Red TOONS™ car is lightweight. Heavier cars may not complete the loop on the first try. If that happens, check the track alignment and adjust the launch speed.

Step-by-step assembly guide

  1. Unbox and sort the pieces: Open the box and separate the Super Speed Playset pieces from the Loop Add-On Kit pieces. Download the assembly manual from the link provided in the product description. Group all connectors and track segments by type. Mistake: mixing pieces from both sets can cause confusion later. Keep them in separate piles until you start each section.
  2. Assemble the Super Speed Playset base: Follow the manual to build the main straight track and the launcher mechanism. Ensure the launcher arm moves freely and locks into the cocked position. Test the mechanism with the Hachigo Red car before attaching the loop. Checkpoint: if the launcher feels stiff, apply a tiny amount of silicone lubricant to the pivot point. Do not use oil-based lubricants.
  3. Attach the Loop Add-On Kit: Connect the loop track segments to the end of the Super Speed Playset's straight section. Make sure the loop forms a complete circle and that the track connectors snap firmly. The loop should sit level on the floor without wobbling. Common mistake: forcing the loop segments together without aligning the tabs can cause them to pop apart during play. Align each tab before pressing.
  4. Test the loop with the included car: Place Hachigo Red on the launcher, pull back the launcher to the first click, and release. Watch the car enter the loop and complete the full circle. If the car stalls, increase the launch power by pulling back to the second or third click. Takeaway: if the car still fails to complete the loop, check that the loop is not tilted and that all track joints are flush.
  5. Expand or customize the layout: Once the basic loop works, connect additional Add-On Kits or Expansion Packs to the free end of the Super Speed Playset. You can also swap in other 1:64 scale cars for variety. The set is compatible with CANDYCAR® and TOONS™ vehicles. Checkpoint: heavier cars may need more launch power. Start with the included car to establish a baseline before introducing other vehicles.
