Very Hard Levels
A hand-picked list of very hard Pixel Flow boards. This section is designed as an editorial challenge shelf for the levels that deserve extra breakdowns, cleaner strategy notes, and deeper blog coverage over time.
What belongs here?
Not every difficult board belongs in this list. The goal here is to collect the levels that feel genuinely demanding because of route conflict, cleanup pressure, center control, perimeter control, key timing, or shape-based misreads.
This page is curated manually, so the list can grow over time as more very hard boards are confirmed and written up properly.
