How Book Of Cats's special symbols work

Golden Book
The Golden Book symbol substitutes for all symbols in the winning line. 3 and more Scatters in the main game trigger 10 free spins with expanding symbol.

Book Of Cats features

Scatter, Wild
The role of the Scatter and Wild symbol in the game plays the Golden Book. This symbol substitutes for all symbols in the winning line. 3 Scatters in the main game trigger the bonus game (10 free spins) with expanding symbol. The Expanding symbol cannot be substituted by the Scatter symbol during the bonus game.
Winline Expanding Feature
In the main game the 6th reel is locked except for one cell. The feature works in case when the winning combination appears on the reels and in the 6th cell appears the same symbol as in this combination. Then the symbol expands to cover 3 positions on the 6th reel, complementing the winning combination.
Free spins
The bonus game starts, when 3 or more Scatters (the Golden Book) appear on the reels. The symbol which appeared in the one opened cell on the 6 reel will play the role of the Expanding Symbol in the bonus game. The Golden Book can't be an expanding symbol. Then the game starts with the unlocked 6th reel. During the bonus round additional Free Spins can be won, the process is unlimited.
Expanding symbol (in the bonus round)
One symbol selected in the 6th cell in the main game, plays the role of expanding symbol in the Free Spins round. During the bonus round and after payout of regular symbols, the special symbol will expand occupying 3 positions on the reel. This symbol plays as a regular symbol even not on the adjacent reels and on all lines played.
The special expanding symbol
The special expanding symbol pays according to its paytable, on all reels, even on non-adjacent positions. Expansion is triggered only if enough symbols for a win are present.
Gamble round
If you win in the main game, the gambling option becomes available to you. To enter the gambling room, click the Gamble button that appears next to the Spin button. The aim of the gambling round is to guess the color or the suit of the face-down card. Your current win becomes the stake for the gambling round. You need to choose Red, Black, Clubs, Spades, Hearts, or Diamonds. If you guess the color, your stake is doubled. If you guess the suit, your stake increases 4 times. If you win, you can collect your winning amount or risk to increase it again. To collect your win and return to the main game, click on the cash-bag. If you lose, the gambling round will stop automatically and you will return to the main game. You can play the Gamble round until your win reaches the limit of ¼ of the maximum win. After each win in the Gamble round the following happens: if your potential next win in the Gamble round exceeds the maximum winning amount, the Gamble round is closed, you return to the main game, and the amount you have already won is accrued to your balance. If your potential next win in the Gamble round does not exceed the maximum winning amount, the Gamble round continues, and you have a choice whether to continue playing or to collect your win. To play Gamble in the Autoplay mode, please tick the checkbox On any win in the Autospin settings menu.
Buy bonus
There is a possibility to buy a bonus: round of free spins. The player can buy a bonus at the price pictured on the button. If the player increases the bet, the buy bonus price will be automatically increased. Spins start after buying the bonus. The next spin triggers a bonus game with free spins. During the bonus round, the button is deactivated.

Book Of Cats: A Purr-fectly Wild Adventure from BGaming


Game Overview & Theme


Book Of Cats transports players to a mysterious, cat-themed ancient world. The reels are set against a backdrop of a dusty temple interior, with stone carvings and hieroglyphs depicting various feline deities. The symbols are beautifully rendered, featuring a collection of adventurous cat characters—each with its own unique personality and headgear—alongside classic card royals (A, K, Q, J, 10) styled with an Egyptian flair. The audio design complements the theme perfectly, with atmospheric music and satisfying sound effects for wins and special features. It’s a cohesive and charming package that will appeal to both cat lovers and slot enthusiasts looking for a familiar yet fresh take on a proven concept.

How to Play Book Of Cats


The game uses a standard 5x3 reel grid with 10 fixed paylines, meaning all lines are active on every spin. Before you begin your expedition, you need to set your bet. The betting range is notably accessible, with a minimum bet of $0.01 and a maximum of $1 per spin, catering to both cautious players and those who prefer a steadier pace. Simply adjust your coin value using the +/- buttons, hit the spin button, and watch the reels turn. The game also includes an autoplay feature, allowing you to set a predetermined number of spins to run automatically. The key to unlocking the game's biggest treasures lies in its special symbols: the Book acts as both a Wild and a Scatter.

RTP, Volatility & Max Win


Understanding a slot's mathematical model is crucial, and Book Of Cats presents a specific profile. The game has a theoretical Return to Player (RTP) of 94%, which is below the industry average. This is an important factor for players to consider, as it indicates a higher house edge over an extended period. More defining is its very high volatility. This means wins won't land frequently, but when they do, they have the potential to be significantly larger than your initial bet. This creates a gameplay experience filled with anticipation and the chance for substantial payouts during the bonus round. For a deeper explore what these numbers mean, check out our comprehensive guide on Slots RTP Explained.

Special Features & Bonus Round


The excitement in Book Of Cats, like in all "Book of" slots, centers on its special features triggered by the sacred Book symbol.



  • Wild & Scatter Symbol: The Book symbol serves a dual purpose. It substitutes for all regular paying symbols to help form winning combinations. More importantly, it is the Scatter. Landing 3 or more Book Scatters anywhere on the reels triggers the Free Spins feature.

  • Free Spins Feature: This is the main event. When triggered, you are awarded 10 free spins. Before the round begins, one regular symbol is randomly chosen to become a special Expanding Symbol. During the free spins, if enough of this chosen symbol land on the reels to form a win, it will expand to cover the entire reel, dramatically increasing the win potential. This feature can be retriggered by landing 3 or more Scatter symbols during the free spins round, adding more spins to your total.

  • Gamble Feature: After any win, players have the option to gamble their winnings in a classic double-or-nothing card guess game. This is a high-risk, high-reward option separate from the base game mechanics.

Pros and Cons of Book Of Cats


Before you decide to explore this feline temple, let's weigh the key advantages and disadvantages.


Pros:



  • Engaging and well-executed cat-themed twist on a popular genre.

  • Very high volatility offers the potential for large, exciting payouts.

  • Simple and intuitive gameplay mechanics, perfect for both new and experienced players.

  • Extremely low minimum bet makes it easy to try without significant risk.

  • The Expanding Symbol in free spins can lead to full-screen wins.


Cons:



  • Below-average RTP of 94% may deter some players focused on long-term value.

  • Very high volatility means potentially long dry spells without wins, which can deplete a balance quickly.

  • Lacks some of the innovative or complex bonus mechanics found in other modern slots.

How Book Of Cats Compares to Other BGaming Slots


BGaming has a diverse portfolio. Compared to their chaotic farmyard fun in Clucking Hell or the cascading cluster pays of Lucky 8 Merge Up, Book Of Cats is a return to a more traditional structure. It shares the "Book" mechanic with other providers but stands out with its unique theme. If you enjoy the straightforward thrill of picking special symbols, you might also like their word-based game Spin And Spell. For players who prefer classic fruit machine vibes with a modern multiway system, Royal Fruits MultiLines is a great alternative. And if you're just looking for lighthearted, fun slot games, don't miss their festive title Lucky Ducky X-mas.

Final Verdict on Book Of Cats


Book Of Cats by BGaming is a solid, if somewhat conventional, entry in a crowded sub-genre. Its greatest strength is its delightful theme and presentation, which sets it apart visually from its many competitors. The core "Book" gameplay is executed reliably, offering that tense, high-volatility experience that its target audience seeks. The major point of consideration is its 94% RTP, which is a tangible mathematical disadvantage compared to many other slots. Ultimately, Book Of Cats is best enjoyed as a fun, high-risk demo experience for those curious about the theme or the mechanics. We recommend trying the free play version right here to feel its unique rhythm before deciding if you want to hunt for its hidden treasures with real stakes involved.
