Book of Cats by BGaming - Slot Overview
Book of Cats is BGaming’s feline take on the legendary “Book” slot formula. Set against a backdrop of sunlit pyramids and ancient temples, the game replaces pharaohs with sacred cats, giving the familiar Egyptian treasure-hunt theme a sleek and distinctive personality. It plays out on a 6×3 reel setup with 10 fixed paylines, offering a slightly expanded stage compared to classic 5-reel book slot machines while keeping the mechanics clean and focused. Visually rich and atmospheric, the game blends golden pyramids and hieroglyphs with sharp animations and a focused, immersive soundtrack. At the heart of the slot is the familiar Book symbol, acting as both Wild and Scatter, triggering Free Spins with a randomly chosen expanding symbol - the feature that fuels the game’s biggest payouts.
Book of Cats design, RTP and volatility
Visually, Book of Cats stands out by giving the familiar Ancient Egypt theme an elegant feline focus. Instead of the usual pharaohs and scarabs, the reels are framed by ancient stone pillars, glowing hieroglyphs, and statuesque feline figures that feel regal rather than cartoonish. The palette leans into warm desert tones and shimmering gold accents, complemented by atmospheric sound design that feels both adventurous and refined. It’s a world that feels alive, where every spin seems to carry you a little deeper into hidden tombs and forgotten temples - but with a sleek, almost cinematic polish that elevates the experience beyond your typical slot backdrop.
When it comes to performance, this is a slot that plays with tension. With an RTP in the mid-90% range, it sits slightly below some industry averages, but the design compensates with high volatility. That means you won’t see winning combinations on every spin, but when the expanding symbol mechanic kicks in during Free Spins, the payoff potential can be significant. The blend of patient base play and explosive bonus rounds gives the gameplay a satisfying rhythm - calm exploration punctuated by thrilling bursts of reward when luck swings your way.
Special Features of Book of Cats
Book of Cats doesn’t try to reinvent the wheel - it refines it. The feature set is tight, focused, and built around one central mechanic that truly drives the excitement. Instead of layering multiple mini-games and modifiers, the slot channels its energy into a classic but powerful bonus structure. It’s a “slow burn into explosion” type of design, where the base game builds anticipation and the bonus round delivers the drama.
The Book symbol - the heart of the game
The magical golden Book symbol is the engine behind everything. It works as both a Wild (substituting for regular symbols) and a Scatter (triggering Free Spins with three or more anywhere on the reels). Because of this dual role, every time the special symbol lands, it matters - either boosting a line win or nudging you closer to the bonus.
Free Spins with expanding symbol
When Free Spins are activated, one symbol is randomly selected to become the expanding symbol for the entire feature. If that symbol lands during the bonus, it expands to fill the entire reel, often turning a small hit into a full-screen payout. This is where the slot’s biggest wins are born - especially when the chosen symbol is a premium cat icon.
Six-reel structure
The 6×3 layout subtly changes the dynamic compared to traditional five-reel Book slots. That extra reel may not seem dramatic at first, but during Free Spins, it increases the chance for additional expanding reels to connect - which can seriously amplify returns when everything aligns.
Gamble feature
After any base-game win, you can enter a Gamble round to try doubling or quadrupling your payout by guessing a card's color or suit. It’s simple, optional, and adds a quick jolt of tension for players who enjoy taking calculated risks.
Book of Cats Symbols Explained
The symbols in Book of Cats feel like they’ve been lifted straight from the walls of a hidden temple - elegant, mysterious, and steeped in ancient reverence. The entire set revolves around sacred felines, inspired by the cat goddess Bastet and Egypt’s historic worship of cats. Rather than cartoonish mascots, these cats are presented as divine figures: poised, jeweled, and powerful. They aren’t just decorative - they are the soul of the game’s identity.
Cleopatra is the crown jewel of the game and the undisputed queen of the paytable. Regal, adorned in gold, and commanding, she’s the highest-paying regular symbol on the reels. Flanking her are the sacred icons of feline mythology. The green Bastet cat radiates divine protection and grace, while the purple Pharaoh cat mask adds an air of mystery and ceremonial grandeur. Completing the premium lineup is the Ankh, the ancient Egyptian symbol of life - gleaming in gold and reinforcing the game’s spiritual undertone. These symbols carry the real weight of the paytable, and when they appear in clusters, you can feel the momentum shift.

At the center of the mechanics is the glowing Book symbol, the most important icon in the game. It acts as both Wild and Scatter. As a Wild symbol, it substitutes for all standard paying symbols to help complete combinations. As a Scatter, landing three or more anywhere on the reels triggers the Free Spins feature. Its ancient, spellbook-like design ties directly into the expanding symbol mechanic that defines the bonus round.
Completing the set are the lower-paying A, K, Q, J, and 10 symbols, styled with subtle Egyptian accents so they blend seamlessly into the desert aesthetic. They land frequently, forming smaller wins and keeping the gameplay flowing between the bigger cinematic moments. The balance between character-driven feline icons and classic slot royals keeps the atmosphere immersive, elegant, and consistent from the first spin to the final expanding reel.
How to Play Book of Cats
Choose your stake
Before entering the temple, set your bet size. With 10 fixed paylines across a 6×3 grid, all you need to adjust is your total wager - pick an amount that fits your bankroll and your appetite for volatility.
Spin the reels
Press spin and let the six reels unfold. Winning combinations pay from left to right, and the Book symbol can step in as a Wild to help complete lines in the base game.
Watch for the Books
Land three or more Book symbols anywhere on the reels to trigger Free Spins. Every Book that appears builds anticipation - it’s either helping a win or setting up the bonus round.
Maximize Free Spins
During Free Spins, one symbol is randomly chosen to become the expanding symbol. When it lands, it stretches to fill the entire reel - this is where small wins can suddenly transform into major payouts.
Decide on the risk
After any base-game win, you can enter the Gamble feature to try doubling or quadrupling your payout by guessing a card. Collect safely - or push your luck for a bigger reward.
