How to Solve Loop Sort Level 137 — Full Solution
- Release the top orange truck on the left source wall and let its cubes travel around the U's upper bend, down the right vertical lane, and back through the lower return.
- Stagger the yellow, blue, and purple layers from the second source truck, sending each colour only after the previous wave has cleared the narrow upper bend.
- Keep the empty third source and the covered left-wall panels closed until the first receivers on the right side of the U are open and checked.
- Route the early green and red waves through the long U one at a time, waiting for each to clear the bottom return before the next enters.
- Use the checked receivers to open the lower red, gray, and blue reserve trucks on the left source wall, routing each through the same U circuit.
- Finish the remaining pink and blue traffic through the lower return and wait for all seven colour groups to show checks.
Colors in this level:
Orange, Yellow, Blue, Purple, Green, Red, Gray, Pink
Common Mistakes to Avoid
- Releasing a second source before orange clears the U's top bend.
- Treating the lower red, gray, or blue covered trucks as opening lanes.
Quick Tips for Loop Sort Level 137 (spoiler-free)
- Give orange a full pass through the top bend before using the next stack.
- Release yellow, blue, and purple as separate waves.
- Save the large lower reserve trucks for their checked reveals.
Board notes 5 details
- Layout
- A tall U-shaped loop occupies the right side while stacked horizontal source trucks line the left; three large covered trucks form the lower reserve.
- Goal
- Check seven colour groups through the long upper bend and bottom return as the left source wall and covered reserve reveal new layers.
- Opening
- Release the top orange source first, then stagger the yellow-blue-purple stack after the first wave clears the U's top bend.
- Danger Zone
- The U's top bend and bottom return are shared queue sections; a second source released too early can hide the next receiver behind a full vertical line.
- Mechanics
- Multiple source heights feed one elongated U, and the large red, gray, and blue bottom trucks remain covered until later checks.
Frequently Asked Questions
What is the first release in Loop Sort Level 137?
Start with the visible orange truck at the top of the left source wall.
Why is this level easy to block?
The top bend and bottom return are long shared sections, so one early release can fill the entire U-shaped queue.
