Car Sort: Color Puzzle Level 172 Solution Walkthrough

Board Shape

Level 172 is a box loop with center shelves. The opening layout shows a rectangular road surrounds center shelves, with bottom garages lined under the loop. 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:

green left pocket -> blue upper shelf -> yellow center shelf -> pink right block -> red bottom group -> purple cleanup

The important idea is to start with green left pocket, then use the space from that group to reach pink right block. Save purple cleanup for cleanup, when the board has fewer blockers and the matching garage path is more direct.

Safe Route Order

1. Start Level 172 with green left pocket, since that batch loosens the entrance before the lower cars need to travel.
2. Bring out blue upper shelf at this point in Level 172, when the road has a single direction and the matching garage path is no longer hidden.
3. Treat yellow center shelf as a controlled middle release for Level 172; clear the blocker in front of it before starting another shelf.
4. For Level 172, move pink right block only after the lane from the previous batch is open; this keeps the next shelf from feeding into mixed traffic.
5. Use red bottom group as the next checkpoint in Level 172, because it spends the space created by the prior group instead of competing for the same road.
6. Use purple cleanup as the Level 172 cleanup group, when earlier shelves have stopped blocking the final path.

Read the replay by lane space rather than by the nearest visible car. If the next color in the route is blocked, clear the front car that is physically holding the road mouth, then return to the planned color batch. Do not start a second deep stack just because it is visible; Level 172 rewards keeping one clean lane open.

Fixing A Jam

Keep one side of the box empty; once both bends hold mixed colors, there is no room to rotate the next batch. If your board no longer matches the route reference, look for the area that should have opened after green left pocket. 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 pink right block and then the late cleanup group. This keeps the Car Sort: Color Puzzle Level 172 solution stable without needing a perfect tap-for-tap replay.
