Book of Ra™ Deluxe — Buy Bonus is an exciting video slot game crafted by Greentube (NOVOMATIC), inspired by the classic Book‑of mechanic. This game retains the traditional structure of the Deluxe edition while introducing an optional Bonus Buy feature, allowing players to jump straight into the Free Games round, subject to market and operator settings.
Game Overview
The game features a standard 5×3 reel layout with 10 fixed paylines, rewarding winning combinations from left to right on adjacent reels. The Book of Ra symbol is pivotal, serving as both Wild and Scatter, and unlocking the Free Games feature with an expanding special symbol.
Book of Ra™ Deluxe — Buy Bonus is characterized by high volatility. The potential for wins is primarily concentrated in the Free Games mode, where a randomly selected symbol expands to cover entire reels and pays across all active paylines.

The Book of Ra symbol substitutes for all regular symbols and acts as a Scatter. Besides triggering bonus rounds, it also pays scatter awards when three or more appear on the reels.

Free Games with Expanding Symbol
The Free Games bonus is activated by landing three or more Book of Ra symbols anywhere on the reels. Players are awarded ten Free Games, and one regular symbol is randomly chosen as the Special Expanding Symbol for the entire bonus round.
Whenever the selected symbol forms a winning combination, all its instances expand to cover their reels and pay on every active payline. Additional Free Games can be retriggered when three or more Book symbols appear again, adding ten extra spins while maintaining the same expanding symbol.
Buy Bonus Feature
Where allowed, the Buy Bonus option enables players to access the Free Games mode instantly without waiting for Scatter symbols. This version may function under a different RTP configuration compared to the standard Deluxe build.
Gamble Feature
After a successful win, players have the option to activate a gamble feature to try to double their payout through a red‑or‑black card prediction. The availability of this feature is subject to jurisdiction and operator rules.
