Slot Summary

A symbol that turns gold, fills its reel, and produces an additional payout gives Book of Riches its defining mechanical promise. RubyPlay places that transformation inside an Ancient Egyptian archaeological story about recovering lost relics and opening a magical book. The same idea carries into Free Spins, where one random symbol receives the gold treatment, concentrating a Medium volatility game on a visible symbol change rather than a long chain of separate bonuses.
MechanicsSelected symbols turn gold and expand reel-high

How It Plays

Book of Riches uses 5 reels, 3 rows, and 10 Paylines. Regular combinations resolve first before the selected gold symbol can expand and create an additional payout.

The symbol change can occur during ordinary spins, giving the base game a second evaluation tied to one transformed symbol rather than adding a separate reel set.

Theme & Atmosphere

Ancient Egypt is presented through an archaeological expedition, lost relics, buried Treasure, and the search for a magical Book rather than a royal court narrative.

The Action and Adventure framing casts the player as part of an excavation team, while Animals and Carnival elements remain secondary to the tomb-search story.

Action & AdventureEgyptBookAnimalsTomb RaiderCarnivalTreasureAncient

Features & Win Potential

Mystery Symbols provide the central transformation: one symbol can turn gold, and matching instances then expand across their reels after the original payout is settled.

Stacked Symbols support fuller reel coverage, while the Wild Symbol and Scatter Symbol handle substitution and access to the separate Free Spins feature.

Bonus & Free Spins

During Free Spins, a random symbol is chosen to turn gold. After regular payouts, that selected symbol can expand to fill its reel and award an additional result.

Bankroll survival simulator

How long could a bankroll last on Book of Riches? We simulate thousands of sessions from this game's published RTP and volatility — the long-run math, not a prediction of your next spin.

Volatility tier: Medium

Running simulation…
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). The model is calibrated so the average return equals this slot's published RTP (94.89%), with wins capped at its top multiplier (5,100×).

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.
