How to Solve Car Sort Level 177 — Full Solution
- Shorten the roof towers so the upper chamber stops dropping mixed traffic into the shared road.
- Use the 2 and 3 domes as relay buffers while the yellow strip and green box are still part of the upper release.
- Keep the lower receiver room temporary until the upper chamber and both domes are mostly clean.
- Once the first room is quiet, flatten the yellow strip and green box and pass the remaining traffic into the lower room.
- Finish the lower receiver room only after neither dome needs to send cars back upward.

Quick Tips for Car Sort Level 177 (spoiler-free)

- Let the middle yellow-green block settle before the basement closes.
Board notes 5 details
- Layout
- Four roof towers feed an upper chamber with dome buffers marked 2 and 3, a yellow strip and green box in the middle, and a separate lower receiver room.
- Goal
- Quiet the upper chamber first, complete the dome handoff second, and finish the lower receiver room only after the shared S-road belongs to the lower half.
- Opening
- Trim the roof towers, use the domes as relay space, and keep the lower room flexible while the upper chamber still owns the road.
- Danger Zone
- If the lower room or the yellow strip hardens before the dome buffers finish their handoff, the last upper release has nowhere safe to land.
- Mechanics
- The two domes are the bridge between the rooms and should stay relay pieces until the upper chamber is already quiet.
Frequently Asked Questions
What controls Car Sort Level 177?
The dome buffers control the board because they bridge the upper chamber and lower room during the only safe handoff.
Why does the lower room reopen in Level 177?
Because the upper chamber or one dome still uses the same S-road when the basement closes too early.
