How the Game Plays

Book of Books is a unique take on the classic "Book of" genre, developed by Peter & Sons in collaboration with Yggdrasil. Rather than the typical Egyptian setting, this title transports you to a medieval forest where a trio of quirky musicians, known as the Order of the Peregrin, guard ancient secrets. The base game starts on a standard 5x3 grid with 10 paylines. Winning combinations are formed by matching symbols from left to right, featuring medieval icons like kings, wizards, knights, and various weaponry. A Golden Bet option is available to increase the likelihood of triggering the main bonus features.

Free Spins Explained

The free spins round is triggered by landing three or more Book Scatters. The number of triggering symbols determines the starting grid size: three scatters provide the standard 5x3 layout with 10 lines, four scatters expand it to 5x4 with 20 lines, and five scatters unlock the full 5x5 grid with 40 paylines. During the round, a random symbol is selected to act as an expanding scatter pay on every spin. These symbols expand to cover entire reels and pay out from any position, provided enough of them are present.

PowerUp Collection Explained

One of the most innovative features of the game is the PowerUp Collection mechanic. Whenever exactly two scatters land in the base game, they award a random PowerUp that is stored and applied to the next free spins trigger. These bonuses can include additional free spins, extra expanding symbols, or win multipliers that apply specifically to the expanding symbol payouts. This system ensures that even "near-miss" spins contribute toward a more potent bonus round later on.
