How to Solve Loop Sort Level 428 — Full Solution
- Release light blue and let it cover the top and right sides before another source enters.
- Send black after the blue tail clears the upper-right corner, then route white on the next circuit.
- Clear red from the center-left feeder once white reaches the lower-left side.
- Open the first exposed lower source and route yellow before orange.
- Send green and purple separately, followed by brown after the green receiver checks off.
- Clear the next red and green layers revealed under the blue covers.
- Route the late pink and gray cargo, keeping pink behind the last green band.
- Finish the remaining yellow, green, pink, and orange endpoints and confirm all eight groups complete.
Colors in this level:
Light blue, Black, White, Red, Yellow, Orange, Green, Purple, Brown, Pink, Gray
Common Mistakes to Avoid
- Treating the five luminous blue blocks as already completed trucks instead of covered sources.
- Opening a lower yellow or green stack while white and red still share the lower-right corner.
- Feeding purple and brown into the green band before its receiver checks off.
Quick Tips for Loop Sort Level 428 (quick clues)
- Leave the covered lower row untouched until white and red separate.
- Keep green and purple on different circuits before brown enters.
- Use eight HUD checks rather than the disappearance of the blue covers as the finish cue.
Board notes 5 details
- Layout
- A rectangular loop surrounds five tall top stacks and three horizontal center trucks, while five luminous blue covers conceal the lower source row. Visible top cargo includes pink, green, orange, yellow, white, red, gray, black, purple, and brown.
- Goal
- Empty the top and center sources, reveal all five lower stacks, and clear their replacement cargo until eight HUD groups complete.
- Opening
- Release light blue, follow with black after the upper-right corner opens, and route white before introducing center-left red.
- Danger Zone
- The center trucks and covered lower sources share the lower-right corner, so exposing yellow or green during the white/red transition creates a four-color queue there.
- Mechanics
- Five blue covers hide a full second source row that reveals yellow, orange, green, pink, gray, and brown cargo after the opening phase.
Frequently Asked Questions

They reveal a second row of colored source stacks, including yellow, orange, green, pink, gray, and brown cargo.
Which colors should run before the lower row opens?
Establish light blue, black, white, and red first so the lower-right entry has space for the revealed stacks.
