Loop Sort level guide
Loop Sort Level 397 Walkthrough
Level 397 wraps a compact rectangle around three color-coded padlocks. Open with bottom-center brown, lower-left light blue, and bottom-center red, then route the blue, purple, and yellow keys one phase at a time.

How to Solve Loop Sort Level 397 — Full Solution
- Release bottom-center brown into the exposed upper-right brown receiver.
- Route lower-left light blue next, then release the red layer exposed in the bottom-center source after brown clears.
- Keep matching exposed colors until the blue key appears; route it to the blue lock, wait, and drain the unlocked bay before the purple key.
- Drain the blue-gated phase before routing the purple key and clearing the purple-gated colors.
- Route the yellow key only after the purple phase checks, then send the last gated cargo through the lower-right corner by itself.
- Release the remaining upper light-blue source, then the upper-right yellow source; the last absorption returns the HUD to 0/6.
Colors in this level:
Green, Yellow, Gray, Orange, Pink, Light blue, Red, Brown, Blue, Purple
Common Mistakes to Avoid
- Starting with orange instead of the exposed bottom-center brown source.
- Treating a disappearing lock as if the newly available cargo had already cleared.
- Opening the purple and yellow phases together at the shared lower-right corner.
- Reading the changing `0/6` HUD fraction as six completed groups or a move limit.
Quick Tips for Loop Sort Level 397 (quick clues)
- After a key removes its lock, drain the newly available bay before routing the next key through the lower-right corner.
- Finish one gated phase before routing the next key.
- Keep an empty circuit for the final upper light-blue and yellow sources.
Board notes 5 details
- Layout
- Three tall upper bays and a lower source bank sit inside one rounded rectangle; purple and yellow locks sit above, while a blue lock blocks the lower-right bay.
- Goal
- Match sources to receivers, route each key to its same-colored lock, and check every upper and lower bay.
- Opening
- Release brown from the bottom-center source into the upper-right brown receiver, then lower-left light blue, then the red exposed behind brown.
- Danger Zone
- A visible key, its matching lock, and the cargo behind that lock are separate states; starting the unlocked bay too soon mixes phases at the lower-right corner.
- Mechanics
- The verified lock chain is blue, then purple, then yellow, with each key wave removing only the same-colored padlock.
