How to Solve Loop Sort Level 451 — Full Solution
- Tap far-left upper orange; it enters at the upper-left entry and starts toward the orange receiver.
- Before orange drains, tap the newly exposed far-left purple face; purple joins the active loop behind orange.
- While both circulate, tap red in upper column three; red enters from the top toward the red receiver.
- Tap orange in upper column two when available; use the orange receiver state rather than waiting for an empty loop.
- Tap gray exposed in upper column two; wait for that column's check/reveal.
- Tap gray exposed in upper column three; its receiver clears the column and advances the curtain.
- Tap green in upper column four; it enters from the top and runs to the green receiver.
- Tap purple exposed in upper column four; wait for its check and the upper-right curtain retraction.
- Tap the first readable pink face in the revealed upper-right area; wait for the pink receiver.
- Tap the exposed light-blue face there; use its receiver/check to expose blue.
- Tap the visible blue face; wait for the blue receiver and lower curtain movement.
- Tap red in the revealed lower reserve; wait for the red receiver to expose gray.
- Tap that lower truck's gray face; its check confirms the reveal.
- Tap the newly readable brown reserve face; wait for the brown receiver.
- Tap late pink after its curtain retracts; yellow, orange, and light blue still remain.
- Tap exposed yellow; wait for the yellow receiver and orange reveal.
- Tap exposed orange; its check reveals the last light-blue face.
- Tap final light blue; its receiver empties the loop and checks the last truck.

Common Mistakes to Avoid
- Waiting for a completely empty loop and thereby losing the video's intended orange, purple, and red opening overlap.
- Guessing cargo behind a red curtain or frosted face.
- Opening the far-right pink/blue stack before the lower reserves have room.
Quick Tips for Loop Sort Level 451 (quick clues)
- Preserve the video's parallel opening taps: orange, then purple, then third-column red before full drain.
- Pause after every curtain retracts and read the newly visible face.
- Do not treat the late pink release as the finish; yellow, orange, and light blue remain.
Board notes 5 details
- Layout
- A rectangular one-way loop separates six upper from four lower positions; four upper columns are exposed but each has a frosted top segment above a readable orange, orange, red, or green face, while red curtains fully cover the upper-right pair and all four lower positions.
- Goal
- Empty every upper and lower bay, route each color to a matching open receiver, and finish with all positions checked and no cubes left on the loop.
- Opening
- Tap far-left upper orange, tap its revealed purple before orange drains, then tap upper-column-three red while both earlier colors still circulate; the video uses parallel opening traffic.
- Danger Zone
- The opening intentionally overlaps orange, purple, and red, so use matching receiver states and truck checks rather than imposing a false empty-loop wait.
- Mechanics
- Checks retract two staged red-curtain banks; covered cargo is read only after reveal, and the last phase continues from pink through yellow and orange to light blue.
Frequently Asked Questions
Which stack should open Level 451?
Start with far-left upper orange, tap its exposed purple before orange drains, then add third-column red while both earlier colors still circulate.
When should the covered lower bays be used?
Use each lower bay only after its red curtain retracts and the newly revealed color can be read from the video-backed board state.
