Book of Books: Slot Overview

Greetings, gamers! If you've ever stood between two mirrors and seen your reflection repeat into infinity, you'll have an idea of the thoughts that come to mind when reading the review for "Book of Books." This online slot game, developed by Armenian company Peter & Sons, follows the long tradition of "book of" slots that began with "Book of Ra" at the dawn of online gambling. As the title suggests, players will encounter expanding pay-anywhere symbols during free spins, as well as other unique features that give the game its own personality.


Unlike many other "book of" slots, which typically take place in or near Egypt, "Book of Books" is set in a medieval-looking wooded land, complete with pointy trees and a trio of musicians playing homemade instruments. This visual style is typical of Peter & Sons' earlier work, such as "Johnan Legendarian" (another "book of" type game) and "Robin Sherwood Marauders." In contrast to some of their recent games that didn't quite match the studio's style, "Book of Books" is a prime example of what makes their visual design so distinctive.




The online slot game "Book of Books" is a creation of Peter & Sons, featuring 5 reels, 3 rows, and 10 paylines. During free spins, the game can expand up to 5 rows and 40 paylines. The minimum bet for this game is $0.1, while the maximum bet reaches $75. The default RTP for "Book of Books" is 96.1%, and it has high volatility. Players can win up to 10000X their bet in the best possible spin, while the hit frequency is 33.26%, meaning a win is awarded on approximately every third spin.


"Book of Books" includes several exciting features, such as the Wild Symbol, Golden Bet, Scatter Symbols, Free Spins, and Bonus Buy, all of which are hidden in a super secret order.


Book of Books: Slot Features

The "Book of Books" slot game features twelve icons, with ten basic symbols that offer instant cash/credit prizes when players land three to five of the same type on one payline. Meanwhile, the five high-paying symbols will award prizes when you have two to five of the same kind. To learn more about the rewards, check out our "Book of Books" slot review.


The four playing card suits - a green Club, a blue Diamond, a violet Spade, and a red Heart - are the first symbols on the paytable, offering 0.5 to 8 times the user's bet. When you land three to five Axes on a payline, you'll receive 1.5 to 10 times the stake.


The high-paying symbols in "Book of Books" include a Hammer, which can help you receive 0.5 to 20 times the total bet, and Swords, which multiply the player's stake by 0.5 to 20 times in combos. The Knight symbol promises 0.5 to 50 times the stake, while the Man in a red outfit can help you get 0.5 to 80 times your bet. Lastly, the King symbol provides 1 to 150 times the total bet, which is the same as the Wild icon.


The only non-paying but essential symbol is the Scatter symbol, and the game has a maximum win cap of 10,000x the bet.




The Book of Books slot offers several powerups that can enhance your gameplay experience. When two Scatter symbols land on the reels, you'll receive bonuses that are only active during the free spins round. These bonuses include one to two free spins, an expanding symbol, and multipliers that apply to all wins on the grid.




To trigger the free spins round, you need to land three or more Scatter symbols on the reels. The number of Scatters determines the size of the playing field and the number of paylines. You'll receive 7 free spins regardless of the number of Scatters, and the powerups are reset when the round ends.




If you manage to land two or more Scatters during the free spins round, you can retrigger the bonus and receive extra free spins and a larger playing field. The Book symbols can also give you additional powerups during this round.




Additionally, the game features a Golden Bet option that increases your chances of triggering the free spins round in the base game. To activate this feature, you need to agree to increase your bet by half.


Lastly, there's a Bonus Buy feature that allows you to purchase the free spins round directly. The cost of this feature depends on the number of Scatters you need to trigger the round, and it also includes powerups and an increased playing field.


Book of Books: Slot Verdict
Peter & Sons' Book of Books slot stands out from other classic 'book slots' by offering a refreshing forest setting and quirky medieval characters. While some purists may not appreciate the liberties taken by the developers, others will enjoy the unpredictability added by the power-up system, expanding symbols, and the fact that the longer you play, the more rewarding the game becomes. With up to 40 paylines and a maximum win of 10,000x your stake, Book of Books is a fun and original addition to the genre. However, players should be aware of the adjustable RTP ranges and the fact that the expanded grid only affects regular wins, not bonus wins. The Golden Bet feature's effect on the chance of triggering free spins is not specified.
