Take a trip back to ancient civilization with the Book of Cats slot! Don’t be confused by the name, though – the slot is not based on cute and cuddly kittens. Instead, it’s based on ancient Egyptian gods with impressive graphics and fun bonus features. One of the more interesting releases in the Book-style category, Book of Cats is designed by BGaming and it offers more in the way of gameplay and features, while keeping the same Ancient Egypt based action. There are some pros there, which will make it appreciated by players that can take a bit of punishing in the hopes of reaching a big prize, but at the same time, a below average RTP will keep more than a couple of them away. The main character of this slot is Bastet, the Egyptian god that looks like a cat, which is unlike most games.

Book of Cats has 6×3 reels and gets only 10 lines. It’s designed as a newest slot with High volatility, where the RTP is a lot lower than I’d like, at 94%. Even so, it’s capable of triggering wins of up to 10,000x the stake, so the potential is still there. For its features, the game mentions the mixed Wild/Scatter Golden Book, along with free spins with expanding symbols, the regular offering from a Book-style slot machine. What is added, is the 6th reel, but more on how that one works below. Book of Cats’ background is more traditional. There’s not a great deal to it, but the tip of an Egyptian longboat is just about visible as it cruises along the Nile, the desert resplendent with palm trees in the background. Music is understated too, but suitably brooding. Learn more about this title right below.

Book of Cats Gameplay

Before starting Book of Cats, there are certain things you can do to set it up under your preferences. You can see the betting amount right below the reels. You can set it from 0.10 to 25.00 per spin. Conversely, playing on the maximum bet settings can lead to a win of x10,000 the stake. The slot has 10 paylines and they are set in place which means all 10 remain active throughout the whole gameplay. On top of that, the game is set on a 6×3 reel making winning combinations easy to come by. Keep in mind that this slot can be played with bitcoin. However, you can play with regular FIAT currency as well.


Hitting the Spin button will start the Book of Cats online slot. The button is on the bottom right side, right below the reels. Right next to it, you can see the Autoplay button which is used to spin the reels automatically. This is a feature often added to slots by game developers. The button to control the background sound is on the top-right side of the reels. However, the game options are set diagonally from the background sounds button. You can find them in the bottom left corner. Right next to the options, there is a big “i” button. Clicking on it will reveal the gameplay, paylines, and all the bonuses.


The impression is that 90% of the slot machines in the Book category will be using themes that are based on Ancient Egypt. It might be more actually. The graphics are certainly good in Book of Cats, and I like how BGaming designed it, but it’s not a very original game in this regard. The Golden Book is one of the major symbols, along with images of Cleopatra and three different symbols which represent the cat goddess, Bastet. You then have five Royals as well, of lower value.

All the cats are different. The green feline (in full Pharaoh regalia) was our favorite – he’s a little mischievous. The purple cat is more magical, as his eyes burn with animated tongues of flame. We’re pleased to say that BGaming didn’t even neglect the low-paying letter/number symbols. These are expertly designed to resemble felines in various poses.

Book of Cats Features and Bonuses

You can expect to land some rewarding features with the Book of Cats slot. The best Book of Cats bonus is the free spins feature, although expanding symbols and wilds are up for grabs. Before diving into that, remember that the slot has an extra reel feature. The sixth reel is usually locked during the base game, except for the middle cell. When you make a winning combination with the symbol in the middle cell, the other cells unlock and the symbol expands. The Golden Book symbol is the wild and scatter of this slot. It can substitute for other symbols on the reels and form a winning combination. Keep reading to learn everything you need to know about the bonus features of this fantastic slot title.

6th Reel Feature

Before we get to the Book-style features, the ones you probably already know all about, there is the matter of that 6th reel to discuss. It’s the one unique contribution that Book of Cats brings to the series. It typically shows up as a reel where only the middle position is uncovered. In order to use it, you first need to have a winning combination of 3+ symbols in the main game area. If the bonus symbol from reel 6 is the same as the one from one of the combinations that forms, then the 6th reel will become entirely covered by that symbol, and it will contribute to the wins formed that spin. This is how you can get to a winning combo of up to 6 symbols.

Book of Cats Gamble Feature

Last but not least, as many casino games have, the Book of Cats slot also has a gamble feature. After every win during the base game, you can opt to play the Gamble Feature to double or quadruple your winnings by playing a card game. Guess either the suit (quadruple win) or color (double win) to match the card revealed. You can keep doubling your wins as long as you get the color or the suit right. However, if you make a mistake, you lose the initial win. That’s why it’s smart to cash out after you double/quadruple your win. BGaming as a developer often add gamble features to their slots. You can read more about such features on their website.

Thrill Factor

There is one more feature that the Book of Cats slot has and we have to mention it. It’s a free spins + expanding symbols feature which is why we consider it to be the Thrill Factor.

Free Spins Feature

Other than that, the features are pretty much as expected. You’re getting a setup which includes a mixed Wild/Scatter symbol, the one showing the Golden Book. You may use this one as a regular substitute when it shows up isolated, or you can get it to trigger free spins if it appears at least three times in view, even if it’s in scattered positions. The Golden Book symbol is the wild and scatter of this slot. It can substitute for other symbols on the reels and form a winning combination. Not only this but if you land three or more on the reels, you get 10 free spins and expanding symbols.

Free Spins Feature

The Book of Cats free spins game is played with the sixth reel unlocked and the symbol on the extra reel acts as an expanding symbol even on the other reels. There’s no limit to how many times you can land free spins. However, that’s not all because this slot title gives players another way of triggering free spins. If you are tired of waiting for the spins to get triggered on their own, you can simply buy them. On the top side of the reels, right next to the name of the slot, the “Buy Bonus” button is located. Clicking on it gives players an opportunity to simply buy the 10 free spins instead of waiting for them to appear through the regular gameplay.

Book of Cats should be lauded for doing what we thought was impossible: finding a new slant on the Ancient Egyptian theme! It does so with a beautifully rendered vision of the desert and a cast of gorgeously designed cats that range from mischievous to a little frightening! The gameplay is just as varied as the cats. The inclusion of a sixth reel matches Book of Cats’ mysterious vibes, but the reel is more than just a novelty. With the Expanding Symbol feature in the base game and expanding symbols during free spins, that extra reel fundamentally affects every single round. A mysterious paytable, quirky gameplay and brooding soundtrack ensure that Book of Cats is a triumph. It’s proof that there’s plenty of life left in Ancient Egypt!

The entire Book series is full of clones, and very few developers try something different in this category. Bgaming does that though, and it offers a 6th reel as the differentiating feature, which might just be enough. It’s a game which pays better than the original, has extra features and it’s still quite volatile. At the same time, it has a 94% RTP, and that’s the one thing that will make me recommend you stay away from this one. It’s a shame really, because finding an original feature in this particular category is hard enough as it is.
