In Book of Books, Yggdrasil reveals the origin of authority and prosperity.

With their most recent publication, Book of Books, Yggdrasil and Peter & Sons have revealed the origin of all books. Yggdrasil is the leading publisher propelling iGaming innovation.

The 5-reel, 40-payline slot offers a distinctive twist on the traditional "Book of" genre and features the distinctive visual language of Peter & Sons.

The feature-rich smash includes powerups like growing symbols and win multipliers, and players can win as much as 10,000 times their initial wager in this game.

In the base game, three scatter symbols anywhere on the reels trigger seven free spins on a 5x3 grid with 10 paylines. The bonus feature will be played on a 5x4 or 5x5 grid with 20 or 40 paylines, respectively, if four or five scatters are present.

In the run-up to the Free Spins bonus, whenever two scatter symbols land, players are given a random powerup that is activated during the round. More free spins, expanding symbols, and expanding win multipliers worth 1x or 2x are all examples of powerups.

With an increased stake, a Golden Bet feature improves the likelihood that a bonus feature will activate. In contrast, a bonus purchase is offered in some countries for between 120x and 500x the bet.

With GATI, Yggdrasil's cutting-edge technology, partners can use the preconfigured, regulation-ready, standardised development toolkit to consistently produce cutting-edge content, followed by quick distribution, for Book of Books.

Stuart McCarthy, Head of Product & Programs at Yggdrasil, said: “Book of Books is a game that we’ve been looking forward to releasing for some time now. Packed with plenty of engaging features, the title sees a classic game mechanic incorporated into the fantastic Peter & Sons art style. We’re thrilled that the YG Masters program continues to facilitate excellent game development, and this is another shining example.”

Yann Bautista, Business Development Manager at Peter & Sons, said: “Working in the YG Masters initiative allows us to focus on creating incredible gaming experiences, and Book of Books is a fun take on the hugely popular ‘Book of’ game style. We want to produce games that put players first, and we’re confident this will be another strong performing game in our offering.”
