Car Sort: Color Puzzle Level 178 Solution Walkthrough

Reading The Board

Level 178 is a tall packed rectangle. The opening layout shows a long vertical rectangle is filled shelf by shelf, with bottom columns acting as late exits. That shape matters because the first few taps decide whether the road stays usable or turns into a mixed waiting line.

Use this route as the practical order:

purple upper lane -> red middle stack -> yellow central row -> blue right edge -> green bottom columns -> cyan cleanup

The important idea is to start with purple upper lane, then use the space from that group to reach blue right edge. Save cyan cleanup for cleanup, when the board has fewer blockers and the matching garage path is more direct.

Route Checkpoints

1. Start Level 178 with purple upper lane, since that batch loosens the entrance before the lower cars need to travel.
2. Treat red middle stack as a controlled middle release for Level 178; clear the blocker in front of it before starting another shelf.
3. For Level 178, move yellow central row only after the lane from the previous batch is open; this keeps the next shelf from feeding into mixed traffic.
4. Use blue right edge as the next checkpoint in Level 178, because it spends the space created by the prior group instead of competing for the same road.
5. In Level 178, green bottom columns is safe once the earlier color has reached its garage; tapping it sooner usually crowds the turn.
6. Use cyan cleanup as the Level 178 cleanup group, when earlier shelves have stopped blocking the final path.

Purple opens the upper lane, red empties the middle stack, and yellow clears the central row. Blue then uses the right edge as a complete batch. Only after blue parks should green leave the bottom columns, followed by cyan. If a bottom car stalls, inspect the tall rectangle for blue or yellow rather than opening another column. The rectangle should be vertically clear at every phase change.

Recovery Notes

Do not start the bottom columns until the tall rectangle has a clean vertical lane through it. If your board no longer matches the route reference, look for the area that should have opened after purple upper lane. Most failed attempts come from moving a lower or side group before that opener has finished.

For recovery, finish the color that already has cars in the road before tapping a new shelf. Once that color reaches its garage, the board usually regains enough space to continue with blue right edge and then the late cleanup group. This keeps the Car Sort: Color Puzzle Level 178 solution stable without needing a perfect tap-for-tap replay.

Before green, the complete right edge and central row should be empty, with no blue car returning from the upper lane.
