Configurable RTP — check before you spin. Book of Cats ships in more than one RTP build (96.99%, 96%, 95%). Operators can license a lower version, so the 96.99% default is not guaranteed at every casino — verify it in the paytable.

What 96.99% RTP means on Book of Cats

Book of Cats carries a published RTP of 96.99%, a theoretical house edge of roughly 3.01% over the long run. Because BGaming ships this game in multiple RTP builds, that edge only holds where a casino licenses the top version; a lower build quietly raises the edge against you, which is exactly why we flag configurable titles instead of quoting the headline unqualified. As always, RTP is a long-run average over millions of spins, not a per-session promise: the edge is real and permanent, and a high RTP never turns a slot into a reliable source of income.

Volatility, max win & features

Volatility is rated very high (5/5). Expect long gaps between meaningful wins, with most of the return concentrated in the bonus — a friendly RTP does not make this a smooth, low-risk grind. The top prize is capped at 8,202x your stake, and the headline features are expanding symbol, free spins, buy bonus, gamble.

Feature buy. Book of Cats offers a bonus-buy. Buying the feature usually changes the effective RTP, so check the in-game info screen for the buy-specific figure.

Our verdict on Book of Cats

3.6/5
Best for: high-RTP hunters who can absorb variance for a shot at the big multiplier
Skip if: your casino only offers a lower-RTP build of this game

Book of Cats is BGaming's cat-goddess take on the book format, with the golden book acting as wild and scatter and one expanding symbol in the free-spins round. BGaming publishes a high 96.99% default; it is configurable, with lower (96% / ~95%) builds possible at some operators, so check the paytable. Three-plus scatters trigger the bonus, a Buy Bonus is available, and a gamble round follows wins. Very high volatility and an 8,202x cap make it a swingy book slot where the expanding symbol in free spins is where big hits come from. It is provably fair with SHA-256 client-seed verification. The slug is 'book-of-cats-bgaming' to disambiguate from other 'Book of Cats' titles. A solid high-variance book option with a strong headline RTP and verifiable spins.
