Book of Cats

Book of Cats is a Egyptian book-style slot from BGaming on a 6×3 grid with 10 paylines. The RTP of 96.99% is very good, the very high volatility brings serious variance, and the maximum win goes up to 8,202x your stake. It follows the expanding-symbol-in-free-spins formula made famous by Book of Dead, but replaces Egyptian gods with feline characters.

Following the Book of Dead template, the free spins feature picks a random symbol to expand across active reels, potentially filling the entire screen. The 6×3 grid with 10 paylines keeps the structure tight, and the very high volatility means the bonus round is where the real money lives. The cat-themed Egyptian styling is charming, blending ancient temples with feline characters. The strong RTP of nearly 97% makes this one of the better Book-style slots available.

With nearly 97% RTP and very high volatility, Book of Cats is one of the strongest Book-style slots available from any provider.

If you enjoy high-variance expanding-symbol gameplay, this should be near the top of your list. Bets range from £0.10 to £30 per spin.

Book of Cats has a Return to Player (RTP) of 96.99%. This sits right at the industry average of 96%, offering fair returns over long sessions. RTP is a theoretical long-term average calculated over millions of spins, not a guarantee for any single session.
