Car Sort: Color Puzzle Level 321 Solution Walkthrough
Route Reference
Key opening, middle, and finish positions for this route.

Open the center before the chained side
Start with dark red from the left center garage, followed by pale violet. Purple is the third center batch and creates the first broad opening through the middle. Blue follows after purple has stopped using the right bend.
Use:
dark red → pale violet → purple → blue → pink upper tower → green → cyan → orange lower reserve → yellow → final red
Pink is the first tall upper release. It lowers the counter beside the chained column and exposes green. Green then clears the long top/right route. Pale cyan follows through the newly opened side.
Orange and yellow are lower reserve phases. Orange uses the left/bottom corner first; yellow follows after that corner is empty. Red is the last substantial column once the chain no longer blocks the right side.
If the center is crowded, finish red, violet, purple, or blue. If the chained side remains closed, complete pink, green, or cyan rather than opening another lower reserve. If the bottom jams, finish orange or yellow before tapping the final red tower.

The Level 321 solution clears the four center garages first, then uses pink, green, and cyan to release the chained side. Orange, yellow, and red finish only after the irregular outer road has become a continuous loop.
Read the hooked road and the chained wall
The outer route bends around a block of four center garages, then narrows beside a vertical chain on the right. Three tall towers stand above and four reserves below. The opening center faces show red, pale violet, purple, and blue, while pink, green, cyan, orange, yellow, and deeper red groups wait outside.
The right-hand chain is not a second lane. Until it releases, traffic must use the hooked lower route and return along the same narrow side. That makes the four center batches the only safe opening.
Start with dark red from the exposed left center face. Pale violet follows after red clears the upper bend. Purple is third and creates a broad middle gap. Blue uses the right side only when purple has fully parked.
At the first checkpoint, all four center faces should be solid or dark, and the road beside the chain should contain no mixed markers. If a pink tower has begun while blue remains inside, finish blue before tapping another outside column.
Use pink and green to pay down the chain
Pink becomes the first complete upper tower. Drain it as one long batch. Its progress reduces the counter beside the chained strip and exposes green. Give green the entire top and right route.
Green often appears both above and inside the board. Clear the complete face connected to the open entrance; do not alternate between the two sources. The second green layer belongs to a later counter.
Pale cyan follows after green. Cyan uses the newly opened right edge and confirms that the chain release is progressing. If the chain remains fully closed, inspect the pink or green tower for a last hidden car rather than opening a lower reserve.
The middle checkpoint shows tall pink, green, and cyan columns above, large red-violet-purple-blue faces in the center, and orange-yellow reserves below. The chained wall should be open or nearly open. Keep the right bend dark before moving to the bottom.
Separate the bottom reserves
Orange is the first useful lower batch. It enters from the left/bottom side and needs the hooked corner clear. Finish orange completely. Yellow follows only after every orange marker has left the bottom edge.
A pale-blue or violet lower column may become visible beside yellow. Treat it as a distinct garage and wait for its full cover to disappear. Starting a partial reserve can leave one car circulating while the remaining source stays locked.
Red returns as a substantial lower or upper column near the finish. It should move after orange and yellow have opened the continuous loop. This late red group is separate from the opening center red.
Clear the deeper center faces after the chain opens
Once the right strip is free, the center garages reveal cleaner vertical columns. Purple, blue, green, red, or pale violet may return. Choose the complete column aligned with the empty right lane.
Clear one center face, reset the road, and then drain one outside tower. This alternating rhythm prevents two long columns from occupying the irregular bends at once. The dark middle gap is your buffer; do not fill it with an unrelated color.
The replay's late board has solid green and blue columns in the middle, red and pink above, and orange-yellow-green reserves below. Finish the inside column touching the route before opening the outer face opposite it.
Final loop after the chain disappears
When the chain is gone, the road becomes a continuous irregular circuit. Purple and blue can complete their deeper center layers, followed by the remaining pink, green, or cyan tower. Red should be reserved for a clean final lap if it is the tallest remaining column.
Before the last group, confirm that the four original center bays are dark, the chained edge is open, and the lower-left hook contains no marker. Release the final column continuously and wait for the last car to pass the formerly chained side.
Recovery around the right bend
If traffic stops beside the chain, complete the active center blue or purple face, or the pink-green-cyan tower currently feeding that side. Opening orange below cannot free the bend.
A jam in the bottom hook belongs to orange, yellow, a lower reserve, or a long center batch nearing the end of its lap. Finish that source and leave the upper towers inactive.
If the chain counter does not advance, find the unfinished car in the current pink, green, or cyan phase. Matching lower colors do not substitute for the upper release. If two colors already share the road, stop tapping and complete the group nearest its destination first.
Level 321 is won by respecting the chain as a true boundary. Dark red, pale violet, purple, and blue clear the interior; pink, green, and cyan unlock the right side; orange and yellow empty the lower hook; then the deeper center and red tower groups use the completed loop. Keep each phase isolated and the awkward road never needs to hold opposing queues.
