The original expanding-symbol book game
Book of Ra Deluxe is the reason every studio has a book slot. Five reels, three rows, ten adjustable lines and one idea executed cleanly: the book is both scatter and wild, and three of them award ten free spins with a randomly chosen expanding special symbol.
That single mechanic is the whole game. If the expanding symbol drawn is a low-value hieroglyph, the round pays modestly. If it is the explorer, the round can pay for the session. Free spins retrigger, which is where the game’s biggest results come from.
RTP, volatility and the honest catch
The theoretical return is 95.10% — below the modern average, and the clearest sign of the game’s age. You are paying a premium for the format that invented the category. Volatility is high: the base game is thin and the free-spins round carries everything.
Bets start at €0.05 a line and the max win sits around 5,000x. The gamble feature after each win doubles or loses, and it is the fastest way to give a good round back.
Who it suits
This is a game for players who want a familiar rhythm rather than a new mechanic. It is instantly readable, it plays the same on a phone as on a desktop, and the tension of the symbol draw at the start of free spins is still the best three seconds in the genre.
At DudeSpin Casino it sits in the classics rack alongside the other Novomatic titles, and it contributes 100% towards the welcome bonus wagering.
