Loop Sort Level 287 Walkthrough
Loop Sort Level 287 links four inner trucks to a right-side source column behind two shutters. Use the yellow-key cargo to remove the upper yellow-lock shutter, then use the purple/pink-key cargo to remove the lower cyan-lock shutter before clearing the mixed yellow-cyan-brown ending.

How to Solve Loop Sort Level 287 — Full Solution
- Route brown from the lower inner truck around the left rail and let that receiver check before touching the right-side column.
- Clear pink and blue from the other lower inner stack, keeping orange in the upper pair staged until the racetrack thins.
- Release the yellow-key cargo from the upper-left inner truck; its check retracts the upper yellow-lock shutter and exposes the first right-column section.
- Use the newly reachable upper-column sources one at a time, routing orange and red only after their matching receivers are visible.
- Return to the lower inner key truck and release its purple/pink key layer; when it checks, the cyan/light-blue lower shutter retracts.
- Work down the newly exposed lower column through green and yellow, then cyan and gray, waiting for each check before uncovering the next layer.
- Let the large red covered pack in the column clear from its dependency instead of treating its red shell as cargo, then use the truck revealed behind it.
- Separate the late yellow and cyan waves from the lower column, waiting until both have crossed the right return before using its last truck.
- Feed the remaining brown release into the receiver space left by yellow and cyan, then wait for the mixed closing phase to clear.
Colors in this level:
Brown, Pink, Blue, Orange, Red, Green, Yellow, Cyan, Gray, Purple
Common Mistakes to Avoid
- Treating the cyan/light-blue lower lock as proof that cyan cargo is the second key.
- Releasing external-column red or orange before the upper yellow-key phase has checked.
- Starting the late brown release while yellow and cyan still share the narrow right return.
Quick Tips for Loop Sort Level 287 (quick clues)
- Match the yellow key to the upper yellow lock, then wait for the shutter to retract before using the top column.
- The lower gate uses purple/pink key cargo even though its padlock is cyan/light blue.
- Keep the right column staged during each key check, especially before the late yellow, cyan, and brown releases.
Board notes 5 details
- Layout
- Two layered trucks sit at the top and two at the bottom inside a tall racetrack; the external right column is split by an upper yellow-lock shutter and a lower cyan/light-blue-lock shutter.
- Goal
- Clear six groups while using the two inner key trucks in order, then drain the newly reachable right-column sources without mixing their deep reveals.
- Opening
- Route brown from the lower inner area, clear the neighboring pink and blue layers, and keep the orange truck staged until the first key receiver checks.
- Danger Zone
- The second key marker is purple/pink, while the shutter it removes is cyan/light blue. Treating the lock color as the key cargo color sends red or cyan into an unavailable receiver.
- Mechanics
- A yellow key unlocks the upper shutter first; a separate purple/pink key later unlocks the lower shutter, exposing two distinct sections of the external column.
Frequently Asked Questions
Which key opens each shutter in Level 287?
Yellow-key cargo removes the upper yellow-lock shutter. The later purple/pink-key cargo removes the lower cyan/light-blue-lock shutter.
Is brown the only final color?
No. Brown is part of the closing release, but the verified ending also carries late yellow and cyan traffic through the right-side column.
