Yarn Loop level guide
Yarn Loop Level 687 Walkthrough
Reduce the top checker strip, red base bar, pale center panel, and both green wing halves together before one wing becomes a tall blade. Level 687 starts symmetrical but stalls in `02:12-02:31`, when a single green wing strip remains with gray stem scraps around it. Keeping both sides shrinking at the same pace is the main requirement here.
Verified Board Notes
- Initial Layout Geometry
- The opening board shows a green-and-white butterfly- or leaf-like figure on a pale background.
- Goal / Target Area
- The green butterfly wings are the main target, but the pale center panel, the top checker strip, and the red base bar all need to shrink together because the late board leaves one tall green wing blade on a thin gray stem.
- Opening Moves
- Start by shaving the top checker strip and the red base bar while clipping both green wing halves and the center body. Keep the wings shrinking together so one side does not remain as a tall blade.
- Danger Zone
- The slowest stretch is about 02:12-02:31, when only a single green wing blade remains with a few gray stem scraps still hanging around it. Pressure drops once the last tall green strip finally shortens.
- Unique Mechanics
- Level 687 is symmetrical at first, but it does not stay balanced. One wing usually survives much longer than the other, so the endgame becomes a narrow vertical cleanup instead of a centered finish.
Quick Tips for Level 687 (spoiler-free)
- Trim the top checker strip and red base bar before one wing half outlasts the other.
- During `02:12-02:31`, shorten the tall green wing blade and the nearest gray stem scrap before singles.
- Remove loose gray and green crumbs early so the final wing strip is not surrounded by extra debris.
How to Solve Yarn Loop Level 687 — Full Solution
- Open on the top checker strip and the red base bar while clipping both green wing halves and the pale center body.
- Keep cutting through the middle so the wings shrink together before one side turns into an isolated blade.
- Take loose gray and green crumbs as they appear instead of saving them for the final cleanup.
- In `02:12-02:31`, work on the tall green wing strip and the nearest gray stem remnant before isolated dots.
- Finish on the last green pixels, pale body crumbs, and top or bottom bar scraps once the tall wing stops standing on its own.
Common Mistakes to Avoid
- Attempting to solve without mapping the entire dependency chain between all color routes.
- Treating all colors as equal priority — find the route that will be blocked first and clear it.
- Missing the cascade technique: intentionally opening one route to unlock two subsequent clears.
Frequently Asked Questions
Why does Level 687 stop feeling symmetrical near the end?
The unique mechanics say one wing usually survives much longer than the other. That is why the finish becomes a narrow vertical cleanup instead of a centered, balanced clear.
What should I prioritize during `02:12-02:31` on Level 687?
Target the tall green wing blade first with the nearest gray stem scrap. The danger note says that exact shape is what slows the board once the rest of the figure has mostly collapsed.
Why are the top checker strip and red base bar important on Level 687?
The opening route pairs both bars with the green wings and center body. If those bands lag behind, they add extra scraps while one wing is already trying to finish as a tall blade.
