Theme, Setting, and Visual Design

Core Gameplay Mechanics and Flow
To initiate a game round, players must place bets on one or more paylines using either the fixed Lines feature or the Flexi Play function (more on this in a later section).

Wild Symbols, Scatter Symbols, and Special Icons
The Wild icon takes the shape of an ancient tome with mysterious symbols etched onto its cover. It substitutes for all standard playing card icons (9-A) to form winning combinations.
Bonus Features and Bonus Rounds
To trigger the bonus round, three or more Book scatter symbols must appear anywhere on reels 1-5 within a single spin. This will activate up to 10 free spins with multipliers ranging from 2x to 20x in each round.
During free spins, any winning combination is multiplied by an increasing multiplier (e.g., x2 for two monsters and x4 for three).

If four or five scatters land during this feature, an instant win cash prize may be awarded.
