Book of Cats is a 2020 BGaming slot that takes the expanding-symbol book mechanic and wraps it in an Egyptian-cat aesthetic — Bastet imagery, hieroglyphics, and feline symbolism across the reels. It’s a high-volatility game with a 5,000x max win and BGaming’s highest-quality 2020 production values, making it one of the more compelling book-mechanic variants in this batch.

The game uses a 5-reel, 10-payline grid with bets from $0.10 to $200 per spin. The Egyptian theme is filtered through the specific lens of cat worship in ancient Egypt — Bastet statues, cat eye symbols, golden scarabs, and hieroglyphic card suits populate the reels. The artwork is notably detailed for a BGaming release, and the Egyptian cat concept gives the game a specific identity within a crowded theme category.

The free spins mechanic follows the book format precisely. When the bonus round triggers, one symbol is selected at random to become the expanding symbol for the duration of the feature. Every time that symbol lands on a reel during free games, it expands to fill the entire reel and pays across all lines regardless of normal adjacency requirements. The key dynamic is the randomness of the symbol selection — premium symbols as the expanding choice produce dramatically larger outcomes than lower-value symbols.

Book of Cats carries a 96.51% RTP — above BGaming’s standard 96% floor — and plays at high volatility. The high-volatility profile is inherent to the expanding symbol mechanic, which concentrates value in the free spins rather than distributing it through base game wins. The max win of 5,000x your stake reflects the feature’s ceiling when the expanding symbol cooperates fully. No bonus buy is available.

Book of Cats is one of the best book-mechanic slots in BGaming’s catalogue, combining the proven format with a distinctive Egyptian-cat theme and above-average RTP. Essential for book game fans.
