Cross-source difficulty research
Hard Pixel Flow levels
This list includes only levels where Google difficulty intent and an explicit Hard or Very Hard YouTube title agree. These are editorial research labels, not in-game metadata.
Google + YouTube research
Cross-source difficulty signals
Every entry requires matching Google hard-level intent and an explicit difficulty label in a YouTube title. These are not official Loom Games difficulty tiers or an objective difficulty order.
How the difficulty list is built
Google Autocomplete and result pages identify hard-level search intent. YouTube evidence must explicitly name the same numbered level as Hard or Very Hard. Google Trends is checked as a third signal, but low-volume long-tail queries often fall below its reporting threshold and are never assigned invented values.
The labels describe cross-source evidence, not official game metadata or a measured move-count comparison. The list is therefore not a harder-to-easier ranking.
