Car Sort: Color Puzzle Level 637 Solution Walkthrough

Reading The Opening Board

Level 637 uses a long H-loop. The upper feed is built from red and purple upper racks; below it sit blue center shelf and green/yellow lower columns. The road looks open at first, but the first bend is controlled by the front cars in the upper feed. The replay shows that the useful space is the lane behind the first turn, so the opening move should make room there instead of chasing the nearest visible color. Because this long H-loop layout uses a upper-to-lower release, wait for the next exposed top car before crossing the bend.

The reliable route is red -> purple -> blue -> green -> yellow. Treat that order as a release sequence rather than a list of isolated taps. Each completed color exposes the next row and widens one section of the road. The key opening blocker is this: The crossbar only opens after the upper purple rack is gone. The lower groups are visible early, but they are cleanup traffic until the middle release has happened. Because this long H-loop layout uses a corner-to-center release, wait for the next exposed top car before crossing the bend.

Opening Pass: Red And Purple

Start with the red group in the upper feed. Move the complete front batch before switching sides. This keeps the first corner one color deep and exposes the purple cars without filling the return lane. If a second red car appears behind a different garage, finish the matching front row first; mixing two colors at this point hides the next blocker. The shape opening makes this front-row confirmation easier to spot than the lower colors. Because this long H-loop layout uses a corner-to-center release, wait for the next exposed top car before crossing the bend.

Continue with purple once its shelf is readable. The important checkpoint is a visibly longer empty strip after the first bend. When that strip appears, the opening is correct. Do not tap the lowest yellow or green bay just because it is uncovered; those cars need the space created by the upper pass. On this board, read the next car from the upper feed rather than from the lower edge. Because this long H-loop layout uses a upper-to-lower release, wait for the next exposed top car before crossing the bend.

Middle Release: Blue And Green

The blue group is the handoff in this level. It sits at the point where the road changes direction, and clearing it releases the green shelf. Keep the active color together through the turn. A partial move that leaves one car parked across the center makes the next shelf appear blocked even though the route is still solvable. On this long H-loop board, that handoff is visible when the central road changes direction. Because this long H-loop layout uses a upper-to-lower release, wait for the next exposed top car before crossing the bend.

After blue clears, use green as the middle checkpoint. The board should now show a clean route from the upper feed toward the lower bank. Pause for the next exposed top car rather than selecting by distance. If the middle row still contains mixed colors, replay the previous batch and wait for its counter to finish before entering the lower section. In the Level 637 replay, the newly exposed shelf is the confirmation that this checkpoint is complete. Because this long H-loop layout uses a corner-to-center release, wait for the next exposed top car before crossing the bend.

Lower Cleanup And Safe Finish

Finish with yellow. Enter the lower shelves one color at a time, using the newly empty center as a buffer. The first lower color should travel through the widest part of the road; the last color belongs in the remaining short bay. This is why the route reference leaves the base until late: it prevents a full lower row from sealing the only exit. Because this long H-loop layout uses a corner-to-center release, wait for the next exposed top car before crossing the bend.

For a clean finish, let every active batch complete its parking animation before changing direction. On Level 637, the final cleanup should leave the shape readable one garage at a time. If two lower colors queue together, send the color already exposed at the front and keep the other shelf untouched until the road segment is empty. Because this long H-loop layout uses a upper-to-lower release, wait for the next exposed top car before crossing the bend.

Recovery Advice

If the road becomes crowded near the first bend, stop opening new garages and complete the color currently occupying that bend. If the bottom columns opened too early, use the center shelf as a temporary buffer and return to the route at blue. When the replay state looks different, compare the visible top car rather than the counter: resume with the first newly exposed match, then continue through green before returning to the lower cleanup. The shape layout makes this pause especially important because its return lane is short. Because this long H-loop layout uses a upper-to-lower release, wait for the next exposed top car before crossing the bend.
