Slot Summary

Released on January 7, 2021, Book of Tombs gives Booming Games a direct interpretation of the Book Of mechanic within an Ancient Egypt expedition. Its book symbol serves as both Wild Symbol and Scatter Symbol, opening Free Spins where a regular symbol is chosen to expand. The 95.42% RTP and High volatility place considerable weight on reaching that transformed bonus state and its x5504.00 ceiling.

How It Plays

The base game uses 10 fixed paylines on a 5x3 layout. Matching symbols pay along those lines, while the book can substitute for ordinary symbols.

A Risk/Gamble game provides a separate choice after eligible wins. That optional step is distinct from the book's Scatter Symbol role and the Free Spins trigger.

Theme & Atmosphere

Ancient Egypt supplies the tomb setting, while Exploration and History frame the player-facing objective as an archaeological search rather than a royal court scene.

Book and Mythology cues converge on the special symbol, making the object that carries the theme also control Wild Symbol substitutions and bonus access.

Action & Adventure Mythology History Egypt Book Exploration Ancient

Features & Win Potential

Expanding Wilds make the book useful during ordinary play, while its Scatter Symbol function supplies the route into the main feature round.

The Expanding Symbols rule changes 1 regular symbol during Free Spins. A separate Gamble option can risk an eligible win without altering the selected bonus symbol.

Bonus & Free Spins

Landing at least 3 book symbols awards 8 Free Spins. Before the round begins, an eligible regular symbol is selected to become the Expanding Symbol.

The selected symbol can expand across its reel during Free Spins, and further book symbols can award Additional Free Spins before the round ends.

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 (High). The model is calibrated so the average return equals this slot's published RTP (95.42%), with wins capped at its top multiplier (5,504×).

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.
