What book of slots are

Book of slots are the book of corner of the catalogue — 88 games from 33 studios that share the theme rather than the maths.

How book of slots work

Theme is art, sound and symbol set; it does not change how a slot pays. Two book of games from different studios can sit at opposite ends of the volatility range, so the reel count, the feature set and the RTP on each game page are what tell you how it will actually play. Use the theme to find something you like the look of, then read the specs.
