Car Sort: Color Puzzle Level 550 Solution Walkthrough
Route Reference
Key opening, middle, and finish positions for this route.

Two-Sided Milestone Layout
The opening board has left shelves, right shelves, a vertical road between them, and large blue platforms at the bottom. Green, pink, white, brown, purple, orange, red, yellow, blue, cyan, and pale purple appear. The main rule is simple: keep the vertical road empty between batches.
Recommended order:
green upper-left -> pink left-middle -> white left-middle -> brown left-lower -> purple center-left -> orange center-left -> red center/right -> yellow right-upper -> blue right-middle -> pale purple right-middle -> cyan lower-right
Green and pink open the left. White and brown clear the middle-left. Purple and orange bridge into the right side.
Left Shelf Opening
Start with green from the upper-left. It clears the top of the vertical road. Pink from the left-middle follows, then white. Brown from the left-lower shelf should move after white, because brown needs the middle road to be open.
The checkpoint is a left side that no longer feeds mixed traffic into the vertical road.
If brown is still on the left-lower shelf, keep the right side closed. Brown uses the same vertical road that the right shelves need later, so leaving it halfway through makes the milestone stage feel much tighter.
Center Bridge
Purple from the center-left is the first bridge color. Orange follows and opens the lower-left turn. Red from the center/right should move after orange. These bridge colors prepare the right shelves.
Do not start the bottom platform while purple or orange is still on the road.
The bridge should look clean before the right finish begins. Purple opens the center, orange clears the lower-left turn, and red removes the last shared blocker between the two sides.
Right-Side Finish
Yellow from the right-upper shelf becomes safe after red. Blue from the right-middle follows, then pale purple. Cyan from the lower-right is a final cleanup group once the right side is open.

Recovery Advice
If Level 550 jams, identify which side is feeding the vertical road. Clear green, pink, white, or brown if the left side is still active. Clear purple, orange, or red if the center bridge is blocked.
If the right side stalls, finish yellow before blue, blue before pale purple, and pale purple before cyan. The milestone board has room only if each right-side group leaves completely.
When the final cleanup hesitates, check the vertical road rather than the bottom platform. A leftover orange or red car on the bridge can hold the entire right shelf even when cyan looks ready to move.
