How to Solve Loop Sort Level 391 — Full Solution
- Tap the second center truck for pink and let it round the shared left side.
- Tap the left-center truck for brown, use it again for the exposed green, then return to the second center truck for red.
- Clear newly available orange and gray without overlapping the center-right blue/brown/white stack.
- Use the first checks to expose the upper white/yellow stack and route white before yellow.
- Read the lower covered bays after they open, then send orange, pink, gray, and green in the observed order.
- Finish with light blue from the upper-left truck, orange from the upper-right truck, and the last brown from the center-right truck; confirm a 0/6 HUD and all checks.
Colors in this level:
Pink, Purple, Brown, Green, Red, Orange, White, Yellow, Gray, Black, Blue
Common Mistakes to Avoid
- Treating purple as the second release instead of using left-center brown after pink.
- Releasing red while brown and green still occupy the return lane.
- Guessing that two purple covers hide matching stacks.
- Reading the fluctuating `0/6` HUD fraction as six completed groups or a capacity limit.
Quick Tips for Loop Sort Level 391 (quick clues)
- Follow the opening pink with left-center brown, not purple.
- Keep red separate from the first brown/green wave.
- Read each covered bay only after its orange, gray, green, blue, black, or brown face appears.
Board notes 5 details
- Layout
- Three upper trucks and a lower reserve bank surround a rounded loop; four upright center stacks show purple/green/brown, red/pink, orange/brown/green, and black/blue/brown/white.
- Goal
- Empty every upper, center, and lower truck until all show checks.
- Opening
- Release pink from the second center truck, then brown and green from the left-center truck before returning to the second truck for red.
- Danger Zone
- Every entry meets at the same two left bends, and purple or question-mark covers do not identify their concealed color order.
- Mechanics
- Center completions expose orange/gray and white/yellow work before late covers reveal blue, black, green, and brown traffic.
Frequently Asked Questions
Why start with pink from the second center truck instead of a purple cover?
Purple covers do not identify their cargo; the opening pink, then left-center brown and green, keeps the shared left bends free before red returns.
What should I do with the question-mark panels?
Leave them unresolved until their actual orange, gray, green, blue, black, or brown faces become visible.
