Car Sort: Color Puzzle Level 556 Solution Walkthrough
Route Reference
Key opening, middle, and finish positions for this route.

Outer Loop With Gem Locks
The opening layout shows upper gates, a central square block, lower gem locks, and side garages. Yellow, orange, cyan, green, pink, purple, red, gray, brown, and blue are visible across the board. The outer road is generous, but the center block makes it easy to trap a color halfway around the rectangle.
Recommended order:
yellow top-left -> orange top-right -> cyan upper/center -> pink center-right -> purple lower/right -> green left column -> blue center-lower -> gray lower-middle -> red lower-right -> yellow final cleanup
Yellow and orange open the top. Cyan and pink unlock the center. Purple and green turn the board into a late cleanup route.
Top Gate Opening
Start with yellow from the upper-left. It clears the first top-road entrance and gives the rectangle a usable direction. Orange from the upper-right follows because it removes the opposite top lock and prevents the right side from becoming a parked queue.
Do not open the bottom gem line yet. The bottom colors need the outer loop, and the top has to stop feeding cars into that loop first. If orange is still sitting on the upper-right, the lower route will hit the corner and stop.
The first checkpoint is a top road with yellow and orange pressure reduced and no mixed color sitting across the upper bridge.
Center Release
Cyan is the middle stabilizer. It appears across the upper center and inner parking area, so moving it clears a lane around the box. Pink follows from the center-right, using the space cyan creates.
Purple should wait until pink has room to exit. The purple group sits near the lower-right and center, and it can clog the rectangular road if the pink cars are still crossing. Once pink clears, purple turns into the bridge between the center block and the lower garages.
Green from the left column is safe after that bridge opens. It travels along the left road and no longer competes with the top gates.

Lower Cleanup
Blue in the center-lower area is the next useful cleanup color. It clears a horizontal pocket below the center block. Gray follows from the lower-middle, then red from the lower-right. Yellow can finish last once the road is no longer shared by two active groups.
The bottom locks should feel delayed, not ignored. They are safe only after the center block has stopped pushing cyan, pink, or purple back into the loop.
Recovery Advice
If Level 556 jams, check the top first. Yellow and orange are the opening gates; leaving either one unfinished makes the outer loop unreliable. If the middle is stuck, clear cyan before pink, and pink before purple.
For a late jam, do not keep tapping the gem-lock row. Reopen the rectangle by clearing the color already on the road, then resume blue, gray, red, and yellow in order. The board has plenty of space once the center block is empty, but it has very little tolerance for mixed traffic around the corners.
