Car Sort: Color Puzzle Level 337 Solution Walkthrough
Route Reference
Key opening, middle, and finish positions for this route.

Identify the three traffic sources
The center box exposes brown, green, red, blue, purple, white, and yellow across layered columns. The left reserve holds long pink, orange, and dark-red rows. The right branch contains pale cyan with smaller blue, yellow, and green groups. The top towers remain chained until the middle counters fall.
Use this route reference:
brown and green center faces → red center row → blue and purple center → white/yellow center cleanup → pale cyan right branch → pink/orange/dark-red left reserve → upper green/pink/orange/blue towers → returning green and cyan finish
The two side reserves should not be active together. Their roads meet below the central garage, leaving only one useful turning cell.
Empty the central three-column garage
Begin with brown from the upper-left center face, followed by green. These two colors open the left side of the inner loop. Red should move next from the deeper middle face because it occupies the lane leading toward the left reserve.
Clear blue and purple as their complete faces appear. Purple fills the central column and needs the space blue creates. White and yellow are the last small center batches. Finish them before opening a broad pink or cyan side row.
After this sequence, the center should contain several dark empty bays and the outside loop should carry no marker. If a center counter still shows an unfinished amount, locate the matching exposed face rather than tapping the chained top towers.
Clear the right branch before the wide left stack
Pale cyan has a short shelf on the right and a direct road connection. Clear it as one continuous batch. Small blue, yellow, or green faces beneath cyan should wait until the active cyan group reaches its garage.
The right branch is complete when its horizontal shelf shows empty dark cells and the lower junction is open. This creates enough space for the much larger left reserve to turn into the loop.
Move pink across the top layer of the left stack, then orange from the row beneath. Dark red follows along the lower row. Do not reverse orange and red: orange uses the free central junction, while red needs the room left by both earlier rows.

Unlock and drain the top towers
The tower row now reveals green, pink, orange, and blue as tall batches. Green is safe first because its route descends beside the open left center bay. Pink follows through the same side. Orange should wait until pink clears the upper road, and blue is safest after orange because it uses the far-right descent.
Some tower faces expose brown or yellow before the next main color. Follow the face nearest the road and finish it completely. The deeper face is only a preview; tapping across columns creates alternating traffic on the top edge.
At the tower-to-center handoff, verify that the left stepped reserve is empty. If a red or orange row remains there, finish it before bringing another tower column down.
Finish the returning center and branch colors
Green returns in a broad center column after the towers release their deeper layers. Clear it before purple or blue cleanup. Pale cyan can also reappear on the right branch; save that batch until the center road is open.
The final board should have the top towers reduced to empty bays, the left reserve showing no colored row, and only one right-side group moving. This state gives the last cyan or green batch a direct exit.
Progress checks for the replay
Use four snapshots to keep your run aligned. First, the center should open after brown, green, and red. Second, the right branch should be dark after cyan. Third, the left stepped reserve should shrink from pink to orange to red without two rows sharing the road. Fourth, the top towers should descend into an otherwise empty junction.
If your board differs at one snapshot, return to that phase rather than copying the next visible move. The later tower order assumes that every earlier traffic source has stopped. This is especially important when green appears again: the opening green face, upper green tower, and late green center column are separate groups with separate entrances.
Recovery advice
A jam inside the center means one of brown, green, red, blue, purple, white, or yellow was split during the opening. Complete its visible center face before touching a side reserve. Traffic stuck at the lower junction points to unfinished cyan on the right or pink, orange, and red on the left.
If a tower car enters early, finish its exposed top face only when the center junction is clear; otherwise clear the nearer side-reserve blocker first. Never open both the pink left row and cyan right shelf as a rescue attempt. Restart only if partial batches from both branches occupy the junction and their remaining source faces are still covered.
The Level 337 solution uses the center as a shared buffer. Clearing its compact columns opens the right branch, the right branch makes room for the wide left stack, and those two completed side areas provide enough road for the tall top towers and returning center colors.
For the last move, verify that the lower junction is empty and the right branch contains no pale-cyan marker. The final green or cyan group should cross the junction without pausing. If it stops, a small yellow, blue, or white face remains in the central garage and should be completed before cleanup resumes.
