About Black Cat Book Club
Black Cat Book Club is an idle game where a cat explores the Sorceress' Library, reading forgotten tomes and gaining magical knowledge. The game blends casual progression with a cozy visual style, letting players watch the cat learn spells while they work or relax.

01 / THE GUIDE
Arcane Library Upgrades
The Arcane Library holds forgotten tomes, each providing a unique upgrade when read. Unlocking these books advances the cat’s capabilities and overall progress. Upgrades are tied to the act of reading, so the more tomes you unlock, the more options become available for further development.
- Observe which upgrades appear first to plan a logical progression.
- Compare the effects of different upgrades to see which align with your play style.

Glyphs and Focus
Glyphs consume Focus to reveal their meaning, moving the cat forward in its reading journey. Each glyph decoded adds to overall progress on a book. Focus acts as a resource that is spent specifically on glyph deciphering, linking resource management to advancement.
- Track how much Focus you have before attempting many glyphs at once.
- Prioritize glyphs that seem to unlock larger sections of a book.

Learning and Casting Magic Spells
As the cat reads, it learns various magic spells, including sigils, summoning seals, alchemy, and astral magic. These spells are presented as part of the reading rewards. Casting is tied to the knowledge gained from books, so expanding the library directly expands the spell list.
- Note which spell categories appear after specific books for targeted learning.
- Experiment with different spell types to see how they fit your idle strategy.
