Common Mistakes to Avoid
- Filling the six-slot route immediately before collecting either shutter key or opening the large green source.
- Clearing T3 too early and losing the green/pink/blue anchor needed after both vehicles change.
- Assuming the right inner vehicle is finished after black/purple/purple/green when it later reveals white.
Quick Tips for Loop Sort Level 539 (quick clues)
- Keep one route slot free before each key and cover animation.
- Preserve T3's green/pink/blue tail for the last phase.
- Treat the two inner vehicles as changing receivers, not static decoration.
Board notes 5 details
- Layout
- Five top sources and an eventual six-position B1-B6 bottom bank surround two inner bays; T4 hides a yellow key, T5 hides a cyan/light-blue key, and the left bay starts under a pink keyhole cover.
- Goal
- Open both lower shutters, use B3's pink key on the left inner cover, clear the large green covered B5, complete both inner vehicles, and check every source at 0/6.
- Opening
- Alternate top white/green from T1-T3 with the right vehicle's black/purple/purple/green requirement, then release T4 black and collect its yellow key for the first lower shutter.
- Danger Zone
- White, black, and green can fill all six slots immediately before a key, cover, or vehicle reveal; preserve T3 and one open route slot.
- Mechanics
- T4 yellow and T5 cyan/light-blue keys open separate lower shutters, B3's pink key opens the left inner cover, and the second shutter completes the B1-B6 bank by revealing mixed B4 and covered B5.
