How to Solve Loop Sort Level 403 — Full Solution
- Release the opening brown wave along the upper shelf, then send purple after brown clears the first turn.
- Route white and yellow through the middle bank, followed by red once the center-to-lower bend opens.
- Clear the exposed green and light-blue layers one at a time through both S turns.
- Finish the remaining open-bank pink, blue, orange, and brown cargo until the curtain sources become available.
- Work across the revealed top row in visible order, separating its gray, brown, pink, orange, and light-blue waves at the upper bend.
- Send the final lower yellow and light-blue cargo and confirm all seven HUD groups clear.
Colors in this level:

Common Mistakes to Avoid
- Releasing light blue while red is still dropping into the lower tier.
- Opening a curtain source before purple and green clear the central bend.
- Guessing a covered or curtained color before it appears.
Quick Tips for Loop Sort Level 403 (quick clues)
- Wait for each wave to clear the center-to-lower bend.
- Finish the visible banks before accelerating the curtain phase.

Board notes 5 details
- Layout
- A tall three-tier serpentine path links four middle stacks, four lower stacks, and five top sources hidden behind red curtains.
- Goal
- Complete seven HUD groups, empty the two visible banks, and route every late curtain reveal through both S turns.
- Opening
- Send brown along the upper shelf, follow with purple, then route white, yellow, and red before introducing light blue.
- Danger Zone
- The middle and lower banks share one tight bend; early light blue or a premature curtain wave overlaps red, purple, and green there.
- Mechanics
- Five curtains conceal a late source row that reveals gray, brown, pink, orange, and light-blue cargo after the open stacks are reduced.
