Car Sort Level 73 Solution Walkthrough
Route Reference
Key opening, middle, and finish positions for this route.

Offset Shelves On Both Sides Of An S-Road
Level 73 uses an S-shaped central road with five short shelves on each side. The left wall begins with cyan/red, purple/yellow, blue/green, orange/cyan, and pink. The right wall holds purple, red, green, yellow, blue, and pale lower rows.
Recommended pairing:
left cyan -> right purple -> left red -> right green -> left blue -> right yellow -> left orange -> right cyan -> left pink -> right pale row -> purple cleanup
Complete one shelf before crossing to its partner. The S-curves are too short to hold opposing colors.
The upper pair opens the first bend. Blue/green in the middle clears the crossing point. Orange and cyan open the lower turn, leaving pink and the pale right shelf for cleanup.
If traffic meets at the center, finish the color already beyond the first bend and stop feeding the opposite wall. If the lower pale row is blocked, pink or cyan remains in the second curve.
Pairing Around Both Bends
Cyan on the left and purple on the right form the opening pair. Let the S-road empty, then use red/green and blue/yellow as the next two pairs. Each completed shelf lowers one entrance without creating opposing traffic.
Orange and cyan open the second curve. Pink and the pale right shelf are the final lower pair, with purple cleanup after the center is quiet.
If one side becomes shorter, work on the exposed shelf of the taller bank. When cars meet, finish the one already past the first bend because it has the shorter route to its garage. A stalled pale car is evidence that pink or cyan still owns the lower curve; clearing that batch restores the paired rhythm.
The Level 73 board becomes progressively more symmetrical as matched shelf heights disappear. Keeping the two walls balanced is safer than emptying one entire side and forcing every remaining car to cross the S-road.
The center crossing is the first checkpoint. Cyan/purple and red/green should finish above it; blue and yellow then pass through the middle without meeting cars from the roof. Wait for the first curve to clear before starting the second.
Orange and cyan own the lower curve. Pink should remain on the left until cyan parks on the right, and the pale row follows only after pink clears the bend. Purple cleanup then has an empty S from entrance to garage. If two colors meet, close the one already past the central crossing and keep its opposite shelf untouched until the road resets.
Before purple cleanup, check both curves rather than only the center. The upper bend may look open while a pale car is still leaving the lower bend. Waiting for both to clear gives purple the full winding route and prevents a final opposing queue.
