Slot Summary

A tolerance for medium/high volatility and a 94% RTP is the price of entry to Book of Cats, a BGaming variation on the familiar book-slot formula. Its Ancient Egypt setting centers on Bastet rather than a pharaoh, while the special sixth reel gives the expanding-symbol idea a structural role before and during Free Spins. The 10,000x ceiling leaves substantial potential despite the restrained return setting.

How It Plays

Book of Cats uses a 6x3 arrangement with 10 paylines, but the sixth reel begins with only its middle cell active. Matching that cell with a line win can extend the result.

After qualifying base-game wins, the Gamble option presents a separate decision: collect the amount, guess a card color to double it, or attempt a suit for a larger return.

Theme & Atmosphere

Ancient Egypt is presented through Animals and Mythology, with the cat goddess Bastet placed at the center of the story rather than used as a minor symbol.

The Book theme is literal as well as mechanical. A Golden Book represents the key special symbol, linking the Egyptian festival premise to the Free Spins trigger.

Features & Win Potential

Expanding Symbols distinguish the unusual reel arrangement. When the visible sixth-reel symbol matches a qualifying combination, it can occupy all three positions on that reel.

The Gamble feature follows selected wins and offers color or suit choices. Expanding Wilds and the combined Wild Symbol and Scatter Symbol take over during the main feature route.

Bonus & Free Spins

Three or more Golden Book Scatter Symbols award 10 Free Spins. A randomly selected regular symbol becomes the Expanding Symbol, the entire sixth reel becomes active, and further scatters can add more spins.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium-High). The model is calibrated so the average return equals this slot's published RTP (94.00%), with wins capped at its top multiplier (10,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.

01What RTP and volatility does Book of Cats have?

The cataloged version has a 94% RTP and a medium/high volatility profile, with a maximum win capped at 10,000x the stake.

02What is unusual about the sixth reel?

Only its middle position participates initially. A matching symbol can expand across that reel, and the complete sixth reel becomes active during Free Spins.

03How does the Gamble feature work?

After a base-game win, the Gamble feature allows a card-color guess to double the amount or a suit guess to quadruple it. An incorrect choice loses that amount.
