How to Solve Car Sort Level 172 — Full Solution
- Shorten the roof towers so the upper shelves can unload without mixed traffic dropping back into the ring.
- Clear the highest interior shelves before the long dark-red bar starts acting like a finish lane.
- Keep the numbered basement receivers open while the upper half still depends on the square loop.
- Once the top shelves are quiet, flatten the long lower bar and use it to hand traffic down into the basement.
- Finish the numbered basement receivers only after the square ring has stopped serving the top towers.

Board notes 5 details
- Layout
- Three roof towers sit over a square ring with short interior shelves, a long dark-red bar near the bottom, and numbered basement receivers under the frame.
- Goal
- Shorten the top towers first, settle the interior shelves second, and finish the long lower bar plus numbered receivers only after the ring belongs to the lower half.
- Opening
- Trim the roof towers, open the top yellow and cyan shelves, and keep the long lower bar and basement receivers flexible while the ring is still shared.
- Danger Zone
- If the long lower bar or one numbered receiver hardens before the upper shelves release the ring, the lower half loses the only clean release space.
- Mechanics
- The square ring is a shared lockbox route that must pass from the top towers down into the long lower bar and then into the numbered basement receivers.
Frequently Asked Questions
What controls Car Sort Level 172?
The upper roof towers and interior shelves control the board because the lower bar and numbered receivers cannot own the square ring until that upper release is finished.
Why do the basement receivers reopen in Level 172?
Because the upper half still uses the same ring when the lower bar or a receiver closes too early.
