Car Sort: Color Puzzle Level 399 Solution Walkthrough

Read the side-entry staircase

The upper left exposes dark blue and purple towers. The first right shelves show cyan, pink, and blue, with numbered faces hiding deeper green, orange, red, yellow, and white layers. Each cleared shelf opens the next entrance lower down the vertical road.

Use this route:

upper blue/purple → first cyan shelf → pink upper row → blue middle band → green side column → red-orange shelves → returning purple/cyan → yellow broad row → white-pink lower shelves → final blue-green cleanup

The highest complete shelf connected to the vertical road takes priority. A bright lower shelf behind it is not yet safe.

Establish the upper opening

Clear blue from the top-left tower, then purple. Cyan becomes the first complete right-side shelf. Drain it continuously and let the vertical road reset before pink enters.

Pink follows across the upper row. Blue then appears as a broader middle band. Finish blue completely; its empty shelf is the buffer that allows green to descend from the side column.

At the first checkpoint, the top two shelves are dark, the upper vertical road carries no marker, and green forms one connected face.

Release the central shelves

Clear green, then red when red occupies the inside shelf entrance. Orange follows through the space red creates. These two warm-color shelves are long and should never overlap.

The counters expose purple and cyan in deeper layers. Clear purple first if it is higher, then cyan. Do not combine them with the opening towers; their cars enter the road from a lower junction.

Drain the broad yellow row

Yellow spans a large lower shelf and controls the bottom turn. Start only when the vertical road is empty from top to bottom. Tap through the entire yellow face and wait for its last marker to reach the garage.

White and pink are exposed below yellow. Clear the upper connected face first, usually white, and then pink. Switching between them parks cars on opposite sides of the lower turn.

The late checkpoint shows a ladder of dark shelves down the right side, an empty left road, and only blue, green, or one warm-color cleanup row near the base.

Finish from the lowest connected shelf

Blue and green normally make up the last substantial groups. At this point the priority reverses: select the lowest face directly joined to the open bottom turn, finish it, then work outward to the remaining column. A short orange, red, or cyan batch may follow.

Wait for each cover to settle. The next face can appear while the earlier marker still climbs the side road, and tapping then creates a long mixed queue.

Recovery by shelf height

A jam high on the road belongs to opening blue-purple, cyan, pink, or the middle blue band. A blockage halfway down points to green, red, orange, returning purple, or cyan. A car stopped at the lower turn belongs to yellow, white, pink, blue, or green cleanup.

Complete the colored shelf at the same height as the stranded marker. Do not tap another level for a matching color. If a counter remains closed, inspect the shelf immediately above it for a final car.

If two colors occupy the vertical road, stop releasing the lower source and finish the higher one. Restart only if both source faces are covered and neither batch can advance.

Use three staircase checks. After the opening, two upper shelves should be dark. After red-orange-purple-cyan, the central shelves should form an uninterrupted dark band. After yellow-white-pink, the lower turn should be empty and only solid cleanup faces should remain.

Preserve each empty stair tread

Every cleared horizontal shelf becomes a tread used by the level below. Keep that tread dark until the lower group has crossed it. Filling an upper gap with a returning color too early removes the only place where the next vertical column can turn.

The middle blue band should finish before green and red descend. Orange and purple then widen the central step. Cyan is safest after those warm colors because it needs the full outer side of the staircase.

During the yellow-white-pink phase, inspect the lower two treads independently. Complete the face connected directly to the road, then allow the outside group to inherit the empty step.

Before completion, trace the road upward from the bottom turn. Every junction above the final face must be dark. Drain the last connected shelf in one pass. Level 399 rewards height discipline: clearing each shelf creates the entrance for the one below, while chasing colors out of order fills the only vertical route.

Finish calmly.

If two cleanup faces remain at different heights, always clear the higher connected shelf first. Its departure prevents the lower column from stopping underneath an occupied tread. The final road marker should climb past every dark shelf without changing direction.

Wait for the last counter animation to finish before tapping any deeper face. A silent, fully dark staircase confirms that the visible completion group is truly the final batch.

Check the shelf mouths one last time from top to bottom. Each should point into a dark segment of the vertical road. If one mouth still contains color, finish that exact height before releasing the outside column. This keeps the tail of the final group from stopping beneath a hidden shelf car.

The lowest turn should also stay empty while the last stream climbs. A marker resting there belongs to an unfinished lower shelf, not to the final connected tower.
