Book of Books by Peter & Sons - Online Slot Review

Who's looking forward to another "Book of" slot? We probably wouldn't see many hands rising if we asked that question in a room full of slot enthusiasts. Luckily, when seeing such a title coming from an innovative and forward-thinking producer like Peter & Sons, we may expect something more than another Egyptian iteration with expanding symbols. Book of Books doesn't venture anywhere near the "traditional" setting, serving us with a short backstory about a mysterious order of the Peregrin guarding the legendary volume and traveling disguised as minstrels.

The scene comes in a humorous comic style with a quirky vibe. Three odd-looking musicians accompany players continuously, indulging themselves in their beloved activity. A massive stone structure in the middle of the view holds the main playing area with symbols represented by playing card suit shapes, melee weapons, and three characters depicting a soldier, a doctor, and a king. The overall production quality is at a respectable level, although the uniqueness of the style may feel odd for some players. Still, it creates a pleasant gaming atmosphere, plus getting into the right mood proves effortless thanks to an energetic adventure soundtrack played on drums and violins.

How To Win On Book of Books Slot - Features & Mechanics

On the base game's 5x3 grid, wins are dished out from at least 2 (in the case of highs) or 3 (in the case of lows) matching images landing on any of the 10 pay lines. Combinations pay only when starting from the left and aligning on adjacent reels. The paytable offers decent prizes, falling below the active stake only on 3-of-a-kind hits of the two lowest symbols and 2-of-a-kind on all high-value ones except the top king image. That one awards 1 to 150 times the bet, as does the Wild when creating individual combinations. The math profile's volatility is classified as high, meaning a stronger focus on more lucrative and scarce wins.

Powerups

The game comes with 3 progressive counters that affect the next activated bonus round. There's the number of free spins, a win multiplier, and the number of expanding symbols. The last two values start from 1 while the first from 7. Landing 2 Scatters grants a Powerup that will increase the randomly-selected meter. Free spins can grow by 1 or 2, as can the multiplier and the additional expanding symbol always by 1.

Book of Books Free Spins

Scatter symbols open the way to different free spins variants depending on the number of triggering icons in view:

• 3 Scatters - 5x3 grid with 10 pay lines
• 4 Scatters - 5x4 grid with 20 pay lines
• 5 Scatters - 5x5 grid with 40 pay lines

All features collected by the Powerups in the base game are now active, plus there's a possibility to increase them further by landing 2 Scatters. Players can also grow the playing area by landing the corresponding number of Scatters as per the above list.

Expanding Symbols are randomly selected before each free spin, and they award prizes regardless of their position on the reels, as long as there are enough instances on individual columns to form a win. If multiple Expanding Symbols are active, they activate one after another within the same spin.

Buy Bonus & Golden Bet

The Golden Bet function increases the active stake by 50%, boosting the chance of triggering free spins in exchange. However, players can also activate any of the bonus variants instantly for a fixed buy-in:

• 3 Scatters for 120 x bet
• 4 Scatters for 250 x bet
• 5 Scatters for 500 x bet

Powerups are randomized when choosing the buy bonus option, and the more expensive variants don't guarantee better ones.

Book of Books On Mobile

The wacky adventures of the Peregrin also await on all mobile devices. The game runs on the latest HTML5 technology providing a dynamic and uninterrupted experience on any smartphone or tablet. The landscape variant is almost identical to the desktop one, with the UI rearranged to the right-hand side for better access. In the portrait view, the scene loses some of the background, and the setting becomes dominated by the stone frame holding the reels.

Final Thoughts

Whether the creators aspired to create an ultimate "Book of" title or chose such a name only for the story purpose, the slot is more than capable of turning heads. Firstly, it provides a unique environment sporting a quirky art style that perfectly suits a product like an online slot. The theme, even though mysterious and sparingly described, presents a solid foundation for an entertaining tale, leaving plenty of room for interpretation at the same time. Since the stealthy order of Peregrin guards the secrets, we can only presume what wisdom and wealth the great Book of Books possesses. One thing is sure, though. It can dish out a max win potential of 10,000x, which is nothing to sneeze at. Arriving at this magical number is most likely possible through the best free spins variant and after collecting a significant number of powerups to boost the chances. Therefore, some commitment is undoubtedly required if players aim to experience the game's full capacity.

Regarding the gameplay in general, Book of Books offers a great mix of familiar elements from the traditional model, like Expanding Symbols and other versatile functionalities. Multipliers, extra spins, and increasing the number of Expanding Symbols in the bonus round, to be exact. At the same time, it drops a significant "Book of" feature that merges the Wild and the Scatter into one character. Randomizing the active Expanding Symbols during free spins ensures a dynamic feeling but may prove difficult to track at times. However, it provides the possibility to benefit from wins on the entire range of symbols. While in most "books", players rarely experience the bonus with the top character, it may easily drop several times during free spins For all the fans of progressive elements and committing to a slot long-term, it should be a great title to try, especially if the slightly altered "Book of" mechanism in an offbeat cartoony setting is to their liking.
