Yggdrasil and Peter & Sons’ latest partnership is for the Book of Books slot.

Book of Books Yggdrasil

The five-reel, 40-payline slot is a fresh take on the ‘Book of’ genre of titles and incorporates Peter & Sons’ art style.

The game houses power-ups including expanding symbols and win multipliers, with a maximum win of 10,000x available to players.

When three scatter symbols land on the reels during the base game, players will receive seven free spins on a 5x3 grid with 10 paylines.

If four or five scatters land, then the bonus feature is played out on a 5x4 or 5x5 grid, with 20 or 40 paylines respectively.

Meanwhile, a Golden Bet feature – activated by a higher stake – increases the chance of a bonus feature triggering.

Stuart McCarthy, head of product and programs at Yggdrasil, said Book of Books sees a “classic game mechanic incorporated into the fantastic Peter & Sons art style.”

Yann Bautista, business development manager at Peter & Sons, added: “We want to produce games that put players first and we’re confident this will be another strong performing game in our offering.”
