Our take
Medieval fantasy Book slot with 91.93% RTP, high volatility, and creative expandable payline mechanics.
Book of Books from Peter & Sons is the studio's spin on the oversaturated Book slot category, bringing a medieval forest setting with castle walls framing the 5x3 grid. The developer's bold choice to name a Book slot "Book of Books"—a reference to the Bible—signals willingness to challenge conventions. The medieval aesthetic features cartoon knights, kings, wizards, and musicians alongside painted card suits and weapon symbols.
A narrative layer centers on the Order of the Peregrin, guardians of a secret book, providing thematic coherence beyond typical game templates. The King and Wild Coin symbols top the paytable at up to 150x per stake. Base game paylines are fixed at 10, but free spins expand this to 20 or 40, creating strategic variety within the feature.
A trio of medieval musicians performs the soundtrack live in-game, reinforcing the medieval immersion. With a 91.93% RTP and high volatility, Book of Books is a player-unfavorable proposition mathematically, yet the mechanical and thematic uniqueness may appeal to enthusiasts seeking differentiation within the genre. The expandable paylines in free spins are the strongest mechanical draw.
