Car Sort: Color Puzzle Level 523 Solution Walkthrough
Route Reference
Key opening, middle, and finish positions for this route.

Double Vertical Shelves
The opening board shows pink, cyan, green, blue, orange, white, red, purple, and pale purple in two tall stacks. The middle road is only one narrow passage. If two colors enter it together, the right side cannot empty.
Recommended order:
pink upper-left -> cyan left-middle -> green left-center -> blue lower-left -> orange right-upper -> white right-middle -> red right-lower -> purple right cleanup -> pale purple final row
Pink opens the top-left. Cyan and green unlock the left shelves. Blue clears the lower-left before the right side takes over.
Unlock The Left Stack
Start with pink from the upper-left. Pink reduces the first locked layer and makes the central road usable. Cyan follows from the left-middle shelves. Move cyan completely, because it travels through the exact lane needed by green.
Green from the left-center comes next. Green clears the middle of the left stack and exposes the lower blue group. Blue from the lower-left should move after green, not before, because blue needs the left side to stop feeding mixed traffic.
The checkpoint is a clean central road with the left shelves mostly organized.
Do not judge the level by the right side yet. The right stack may look ready, but it is safe only when the left shelf is no longer feeding cyan, green, or blue into the middle. Wait for the central road to look empty before switching sides.
Right Stack Handoff
Orange from the right-upper shelf is the first right-side color to release. It uses the road that the left stack opened. White from the right-middle follows, then red from the right-lower shelf.
Keep orange, white, and red separate. The right stack is tidy only if each color leaves as a full row.
Orange opens the upper right, white clears the middle row, and red releases the lower pocket. If those three are mixed in the central road, the narrow passage loses its only advantage. Let each group finish before choosing the next one.
Final Purple Cleanup
Purple and pale purple are late cleanup colors. Purple clears the right-side finish, while pale purple can leave once the central road is empty. If one left-side color remains exposed, clear it before starting the final purple row.

Recovery Advice
If Level 523 jams, check the narrow central road. Finish pink, cyan, green, or blue before touching the right stack. If the right side was opened early, clear the color already in the road, then return to orange, white, red, and purple in order.
If your state differs from the replay, rebuild from the left shelf. The level is stable only after the left locked layers have been thinned.
For a late recovery, look for the highest exposed right-side color. Clearing from upper to lower usually fixes the stack: orange or white first, then red, then purple. Pulling purple early often traps the last white row.
