Car Sort: Color Puzzle Level 173 Solution Walkthrough

Route Reference

Level 173 is a small island layout. The opening layout shows separate shelf islands sit above and below a short road, so the level is about choosing the exposed island first. 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 island -> cyan upper row -> green middle island -> yellow bottom row -> red lower pair -> blue cleanup

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

Step Notes

1. The first checkpoint in Level 173 is purple upper island; clearing it prevents the opening lane from becoming a mixed queue.
2. Treat cyan upper row as a controlled middle release for Level 173; clear the blocker in front of it before starting another shelf.
3. For Level 173, move green middle island only after the lane from the previous batch is open; this keeps the next shelf from feeding into mixed traffic.
4. Use yellow bottom row as the next checkpoint in Level 173, because it spends the space created by the prior group instead of competing for the same road.
5. In Level 173, red lower pair is safe once the earlier color has reached its garage; tapping it sooner usually crowds the turn.
6. Finish Level 173 with blue cleanup; by then the board should have enough open lane space to avoid another jam.

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 173 rewards keeping one clean lane open.

Late-Board Control

Avoid alternating islands just because they are visible; finish the island that has the open garage route. If your board no longer matches the route reference, look for the area that should have opened after purple upper island. 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 yellow bottom row and then the late cleanup group. This keeps the Car Sort: Color Puzzle Level 173 solution stable without needing a perfect tap-for-tap replay.
