- Tapping upper red while white still occupies the lower return.
- Naming a color behind frost or the striped shutter before it is visible.
Quick Tips for Loop Sort Level 491 (quick clues)
- Use U1-U6 and B1-B6 coordinates instead of identifying a source by color alone.
- Wait for a receiver check or a newly visible layer before the next tap.
- Treat the changing HUD as state, not as a completion target.
Board notes 5 details
- Layout
- U1-U6 sit above a three-run serpentine route. A striped shutter initially hides the lower-left reserve; after the key opens it, the complete lower bank is addressed as B1-B6 from left to right.
- Goal
- Make every receiver show a check, leave the serpentine route empty, and reach the WELL DONE cue.
- Opening
- Tap U3's visible blue layer to reveal white in U3. Tap U3's visible white layer to make the receiver check.
- Danger Zone
- A wave occupies two lower turns for a long time. Wait for the current color to enter its receiver before releasing another visible layer.
- Mechanics
- The key retracts the lower shutter. Covered layers and shuttered bays are described only after the video visibly reveals them.
