F.A.Q.

What is the theme and basic structure of the "Book of Books" slot game?

Based on the text, the "Book of Books" slot game, developed by Peter & Sons, centers around a compelling narrative involving a fictional Order dedicated to protecting a mysterious and powerful book rumored to hold significant power and wealth. The game features a strong medieval theme, visually represented by the characters dressed in period attire, including musicians situated around the reels, and the reels themselves framed by sturdy stone blocks. The core structure of the game starts with a standard layout of 5 reels and 3 rows. This classic configuration provides a familiar gameplay experience in the base game. However, a key dynamic element is introduced during the bonus rounds, specifically the Free Spins feature, where the grid can expand significantly. The number of rows can increase from the initial 3 up to a maximum of 5, which consequently boosts the number of active win lines to 40, offering increased potential for winning combinations compared to the base game's structure.

How are wins determined in the "Book of Books" slot and what are the different symbol types?

In the "Book of Books" slot game, wins are achieved by landing a minimum of three matching symbols on a payline. Crucially, these winning combinations must start from the leftmost reel and consist of adjacent symbols along an active win line, except for Expanding Symbols during the Free Spins which pay anywhere. The game features a variety of symbols, broadly categorized into low-paying and high-paying types. The low-paying symbols include representations of card suits (clubs, diamonds, spades, and hearts) crafted from stone, plus an axe symbol. Landing five of these on a line pays out between 2.5 to 5 times the player's bet. The higher-paying symbols are thematic characters and items such as a sledgehammer, sword, a knight, an old man, and a king. These premium symbols offer much larger payouts, ranging from 10 to a substantial 75 times the bet for a full line of five. Additionally, the game includes a Wild symbol, depicted as a golden "W," which serves as a substitute for all regular symbols (but not the Scatter symbol) to aid in forming winning lines.

What special functions or features are included in the "Book of Books" slot game?

The "Book of Books" slot game is equipped with several distinct special functions and features designed to enhance the player experience and potential payouts. These features are clearly listed within the game's information and include essential slot mechanics as well as unique game additions. The features present are the Wild Symbol, which helps complete winning combinations by substituting for other symbols; Scatter Symbols, which are central to triggering bonus rounds and upgrades; a Free Spins feature, which is the main bonus game offering enhanced winning mechanics; a Golden Bet option, providing players a way to increase the likelihood of hitting the Free Spins; and a Bonus Buy feature, offering direct access to the Free Spins round for a cost. These functions collectively provide dynamic gameplay, from symbol substitution and bonus triggers to direct bonus access and strategic betting options that can influence the game's volatility and potential for large wins, up to the maximum win of 10000 times the bet.

How do Scatter symbols trigger Free Spins and what initial benefits can they provide?

Scatter symbols, represented by the locked book icon, are the primary means of accessing the lucrative Free Spins feature in "Book of Books." Landing three or more Scatter symbols anywhere on the reels during the base game is the standard trigger, which immediately awards the player 7 free spins to start the bonus round. However, the game also offers a unique pre-bonus upgrade mechanism. If a player lands just two Scatter symbols in the base game, it doesn't trigger free spins right away but instead grants a random upgrade that will be applied whenever the Free Spins feature is eventually triggered (by landing 3+ Scatters). These pre-bonus upgrades can add 1-2 extra free spins to the starting total, introduce an additional symbol that will act as an expanding symbol during the bonus, or apply a 1X-2X multiplier specifically to wins generated by expanding symbols. All upgrades collected this way stack and are active throughout the entire duration of the Free Spins session, potentially allowing players to start with more than the initial 7 spins and with enhanced winning capabilities like multiple expanding symbols or increased payouts from them.

How do Free Spins function, including grid changes and symbol expansions?

The Free Spins feature in "Book of Books" significantly transforms the gameplay environment. The layout of the reels can expand beyond the base game's 5x3 structure, contingent on the number of Scatter symbols that triggered the feature: 3 Scatters maintain a 5x3 area, 4 Scatters enlarge it to a 5x4 grid with 20 win lines, and 5 Scatters result in the maximum 5x5 grid featuring 40 win lines. All upgrades earned by landing two Scatters in the base game (extra spins, expanding symbols, multipliers) are carried over and active throughout the Free Spins. During this bonus round, a selected symbol (or multiple symbols, if upgraded) becomes an Expanding Symbol. Whenever enough instances of an Expanding Symbol land on different reels to form a potential win, they will expand to cover their entire respective reels. Expanding Symbols pay out based on the number of symbols present on the reels, even if they are not on adjacent reels or active paylines, after they expand. Wins from Expanding Symbols are calculated after the expansion and are subject to any collected Expanding Multipliers, which are added together if multiple apply. Furthermore, landing Scatters during Free Spins can award additional spins (1, 3, 5, or 7 for 2, 3, 4, or 5 Scatters respectively) and grant another random upgrade, potentially prolonging the bonus and enhancing its features further, while also increasing the grid size if 4 or 5 Scatters land.

Can players influence triggering free spins or buy access directly in "Book of Books"?

Yes, the "Book of Books" slot game provides players with options to either improve their chances of naturally triggering the Free Spins bonus or gain immediate access to it. One method is through the Golden Bet feature. By activating this option, players increase their stake by 1.5 times their base bet. While this costs more per spin, the trade-off is a statistically increased probability of hitting the combination of Scatter symbols required to trigger the coveted Free Spins round during standard play. For players who prefer instant action or guaranteed entry into the bonus, the game includes a Bonus Buy feature. This allows players to directly purchase a spin that is guaranteed to land either 3, 4, or 5 Scatter symbols. By selecting and paying for one of these options, the player bypasses the base game grind and immediately enters the Free Spins feature with the corresponding grid size and initial benefits associated with the chosen number of triggering Scatters, offering a shortcut to the game's main bonus potential.
