Loop Sort level guide
Loop Sort Level 381 Walkthrough
Level 381 uses twelve source bays around one rectangular loop, with four upper sources locked at the start. Release upper orange first, then light blue, and expose the purple, white, orange, and gray dependencies without mixing waves.
If the player asks you to sign in, open the video on YouTube instead.
How to Solve Loop Sort Level 381 — Full Solution
- Release orange from the exposed upper third source and let it spread around the rectangle.
- Release light blue from the upper fifth source and wait for the purple-key unlock to finish.
- Work the lower sources one visible layer at a time until the white key in the second bay opens its matching upper cover.
- Release green, pink, brown, and light blue as separate waves, then expose the orange key in the fourth lower bay.
- Open the orange-covered upper source, then resolve the gray lock only after the active color reaches its receiver.
- Clear the remaining light-blue and yellow sources, then release the lower red source last.
Colors in this level:
Red, White, Gray, Pink, Green, Yellow, Brown, Orange, Light blue, Purple
Common Mistakes to Avoid
- Starting with light blue even though the video releases upper orange first.
- Calling the HUD denominator a number of completed groups.
- Starting the final red source before the preceding light-blue or yellow wave clears.
Quick Tips for Loop Sort Level 381 (quick clues)
- Start with upper orange, not the light-blue key source.
- After the purple, white, or orange key animation, tap only the newly unlocked upper source.
- Read `x/6` as progress for the active receiver color, not six groups left.
Board notes 5 details
- Layout
- Six upper and six lower truck bays feed one clockwise rectangular loop; white, purple, orange, and gray locks cover four upper sources.
- Goal
- Leave all twelve trucks checked after every source feeds its matching receiver, with the lower red source last.
- Opening
- Release orange from the exposed upper third source first, then light blue from the upper fifth source after the route opens.
- Danger Zone
- All sources share the lower-right turn, so a new release can strand mixed colors while the white or orange key is still buried.
- Mechanics
- Purple, white, orange, and gray dependencies reveal covered upper sources; a checked truck is a completed group, not an open receiver.
Frequently Asked Questions
Why start with orange instead of the light-blue key source?
Orange from the upper third source empties the lower-right turn. The upper fifth light-blue stack carries the purple key and should wait until that turn is free.
What does the HUD fraction mean?
It shows cube progress for the active receiver color; it is not a move count or total number of groups.
Which source finishes the level?
The final visible source is the red stack in the lower bank, released after light blue and yellow.
