Hint System Guide
How the H key hint system works in Clean The Library. Resource management, alternatives, and pairing with Shelf Guide.
How Hints Work
Press H on PC (HUD button on mobile) to activate the hint system for your targeted or held book. Hints reveal correct shelf section information—reducing wrong-wing sprints across the two-floor map. Hint usage draws from a finite resource pool that replenishes through normal progression, not unlimited spam.
Hints complement but differ from Shelf Guide magic—hints use hint pool, Shelf Guide uses ability cooldown. No-magic challenge runs rely heavily on hints since major magic is banned—budget across multi-hour sessions.
Roblox library gameplay videos confirm H key binding—same convention as related sorting games in the genre.
Efficient Hint Usage
Use hints on true edge cases: 2C vs 2K purples, 1F vs 1E pinks, 2A vs 2G blues. Skip hints on obvious 1A Horror dark red spines after ten hours experience.
Pair with out-of-game study: read shelf sections on wiki between runs to shrink in-game hint dependence.
Co-op: designate hint caller who burns hints on team ambiguous books while others preserve pool.
Alternatives to Hints
Shelf Guide magic navigates without hint pool cost—trade cooldown instead. Shelf lookup for title search offline.
Insight audits shelves after placement errors—cheaper than hinting every pickup if mistake already made.
