Book of Books Slot Overview

Book of Books is a new casino slot from Peter & Sons with the order of the Peregrin, guarding the most powerful book. It’s the books of books, father of all books, and the source of all power and wealth. It seems like the Peregrin Order is fictional and made up by the game developer, although there are some similar named Catholic orders. There is also a Christian martyr called Peregrine, who died in the second century because he refused to worship the Roman Emperor Commodus. This 5x3 slot can grow up to 5 rows high in the free spins, quadrupling the paylines to 40. Only a very few people will ever be allowed to read the book of books.

Book of Books Slot Information

The members of the Peregrin Order are dressed in medieval-looking clothes. One of them sits to the right of the reels, wearing a tall gray wizard hat and a long gray coat. He’s playing a two-string instrument looking like a double bass. Two other men hang out on the other side of the reels, playing the flute and another string instrument. The reels are in the middle, surrounded by big stone blocks. To make a win, you need to land at least 3 of the same symbols on a payline going left to right, starting with the first reel to the left. The game is available on mobile phones and other devices.

The lower-paying symbols are the playing card suits clubs, diamonds, spades, and hearts made from stone blocks and an axe. They award between 2.5X and 5X the bet for a win containing 5 symbols. The higher-paying symbols are sledgehammer, sword, knight, old man, and a king. Landing a 5-of-a-kind win with them awards between 10X and 75X the bet. The Wild Symbol substitutes all symbols except the Scatter.

Expanding Symbol

Wild Symbol

The Wild Symbol is a golden W that substitutes all other symbols except the Scatter.

Golden Bet

You can pay 1.5X extra per bet to improve the chances of activating the free spins.

Scatter Symbols

The Scatter Symbol is a book with ornaments and a lock. Landing 2 Scatters anywhere gives you a Power-Up that will be used whenever you trigger the free spins. The Power-Up rewards 1-2 additional free spins, an extra Expanding Symbol, or a 1X-2X Expanding Multiplier that multiplies winning from expanding symbols. Landing 3 or more Scatters triggers 7 free spins, where all your collected Power-Ups will be used.

The grid can become bigger in the free spins. Triggering the feature with 3 Scatters gives you the same setup as the regular spins, 4 Scatters equal 4 rows and 20 paylines, and 5 Scatters will provide you with 5 rows and 40 paylines.

Free Spins

You play the Free Spins with 3-5 rows and 10-40 paylines, depending on how many Scatters were used to trigger the feature. The Free Spins are played with all Power-Ups you have collected in the base game, so you might start with more than the 7 starting spins.

For every Expanding Symbol you collect, one symbol will expand to cover its whole reel during the feature. Any Expanding Multiplier is used to multiply all winnings in which Expanding Symbols participate. If you have collected several multipliers, they’re added together. Expanding Symbols can’t be substituted by Wilds, and they pay even if they’re not on adjacent reels.

You’re awarded for landing Scatters in the free spins:

2 Scatter Symbols = 1 Free Spin and 1 random Power-Up

3 Scatter Symbols = 3 Free Spins and 1 random Power-Up

4 Scatter Symbols = 5 Free Spins, 1 random Power-Up, and a 5x4 grid

5 Scatter Symbols = 7 Free Spins, 1 random Power-Up, and a 5x5 grid

The reels are expanded to 5 rows tall in the free spins.

Bonus Buy

The Free Spins are for sale. You have three options of purchasing a spin that guarantees to give you 3, 4, or 5 Scatter Symbols.

Book of Books Slot Conclusion

The number of casino slots containing books is probably higher than there are countries in the world. Book of 99, Book of Fallen, and Book of Fusion are just three of the titles with powerful books. The Book of Books is supposed to be the most powerful of them all, described as the mother of books, whatever that means. If it’s the first book ever written, one can assume it’s not the best.

Anyhow, this medieval-looking setting with square graphics offers quite some action. Your main focus is to end up in the free spins, and you can collect Power-Ups in the meantime, giving you several perks when the feature triggers. The Expanding Symbols become 3, 4, or 5 rows high depending on how many rows you’re playing on. Not only do the expanded symbols increase the chance of making winning combinations, but they also produce wins even if the symbols aren’t on adjacent reels. On top of that is the Expanding Multiplier that multiplies all wins Expanding Symbols are involved in.

Book of Books has a pretty average RTP of 96.1% and a max win of 10000X the bet, which is also common for a highly volatile slot. Anyone interested in secret orders, mysticism, or medieval times will probably love this game.

Book of Books from Peter & Sons has expanding reels and a win multiplier in the free spins.
