Slot Summary

Ancient Egypt provides the familiar starting point for Book of Hidden Tombs, a BGaming release in its Classic collection. Its more distinctive idea concerns the pauses between bonus wins: losing spins can increase the multiplier waiting for a later payout. That gives the established Book-of format a different kind of tension without changing its archaeological identity.

How It Plays

The Book performs two jobs in the base game. It substitutes for other symbols in winning combinations and acts as the scatter that opens the free spins round.

The optional Chance x2 setting raises the wager and doubles the probability of triggering free spins. It changes the chance of bonus entry without guaranteeing an entry on the next spin.

Theme & Atmosphere

Ra, Anubis, and Bastet connect the Egyptian setting to named divine figures. Their presence frames the tomb's treasures as guarded objects, giving the search a specific cast.

A male explorer accompanies those figures as a high-value character. The ancient temple, torchlight, and nighttime setting place his search inside the tomb's surroundings rather than a modern museum.

Bonus & Free Spins

Three or more Books award ten free spins. Before the round, a regular symbol is selected for expansion; when enough copies land, they cover their reels and pay across all ten paylines regardless of their original positions.

Golden Book scatters open Super Free Spins. This version keeps the expanding symbol and adds a multiplier starting at 1x, which doubles after each spin without a win. A payout uses the accumulated multiplier.

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 (97.00%), 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.
