Car Sort Level 121 Solution Walkthrough

Five Center Towers Between Bay Rows

Level 121 has five upper bays, five tall center columns, and five lower bays connected by a rectangular road.

Route order:

upper pink bay -> upper purple -> upper cyan -> cyan center-left -> red center -> pink center -> brown center-right -> top dark/pale towers -> lower purple -> lower green -> lower covered bays

Clear the upper bays before the center columns. Work left to right through cyan, red, pink, and brown, then drain the lower bays.

If the right road fills, finish the active center column. If a lower bay stalls, brown or pink remains above it. Level 121 is ready for cleanup when the five center slots are open and traffic comes only from the bottom.

Separating Bay Rows From The Center

Clear the visible pink, purple, and cyan upper bays first, then finish any remaining dark or pale roof group. No upper car should remain on the rectangle when the tall center columns begin.

Work through cyan, red, pink, and brown across the center. Complete each vertical batch and use its open slot as a buffer. Starting two center columns together fills the right road and removes the turn needed by both.

The lower purple bay begins cleanup, followed by green and the remaining covered bays. Keep this bottom traffic separate from the final center color.

If the right road fills, finish the center column already releasing cars. A stalled lower bay means brown or pink is still active above. Do not open a second lower cover; empty the rectangle, then resume the bottom row one bay at a time.

Five Slots As Working Space

Every completed center tower creates one empty slot that helps the next batch turn. Preserve that space while cyan, red, pink, and brown move across the board. Opening a non-adjacent covered tower may fill the buffer with a color whose garage is still blocked.

The transition to the lower bays is visible: all five tall center positions should be quiet, the right road should be empty, and no roof group should remain on the top edge. Purple can then leave the lower-left, green follows, and each covered bay is resolved separately. If a lower car waits at the right bend, do not add another bottom color. Check brown first, then pink, in the center area. Closing that unfinished tower restores the buffer and gives the current lower batch a complete path to its garage.

Check the five center slots from left to right before every lower cover. An occupied cyan or red slot means the first half is incomplete; an occupied pink or brown slot blocks the exit directly. Complete that column and wait for the rectangle to empty.

During the final covered bays, follow the color that is actually revealed. Park the entire group, keep the neighboring cover closed, and reuse the same empty slot for the next release.
