Book of Ra by Greentube (part of Novomatic) is the original Egyptian “book” slot that inspired an entire sub-genre. Following an explorer into the tombs, it combines a classic layout with free spins and a special expanding symbol that can pay across whole reels. A long-standing land-based and online favourite, it retains steady search demand in the US and across Europe.
This review explains how Book of Ra works, the expanding-symbol free spins, the RTP and volatility, and how to play it responsibly.

Book of Ra is a 5-reel slot (with 9 or 10 paylines depending on the version, including a popular Deluxe edition). The book is both wild and scatter: landing three or more triggers 10 free spins and reveals a randomly chosen special expanding symbol. During the free spins, if that symbol appears it expands to fill its reel and pays across positions, which can produce very large wins.
As the slot that defined the “book” formula later popularised by titles like Book of Dead, Book of Ra carries genuine heritage. Its straightforward design and the drama of the expanding symbol give it lasting appeal among traditional slot fans.
Book of Ra’s RTP varies by version, with the classic typically around 92%–95% and the Deluxe version higher at roughly 94.26%–95.10% — check the figure shown in your specific version, as it is generally lower than many modern slots. It is a high-volatility game, so expect less frequent but larger wins.
The maximum win can reach up to around 5,000x your stake when the expanding symbol fills the reels during free spins. An optional gamble feature lets you risk wins on a card-colour guess to double them, adding further variance.
The defining feature is the randomly selected expanding symbol in the free spins, which spreads across its reel and pays across positions for the game’s biggest wins. The book’s dual wild-and-scatter role and an optional double-or-nothing gamble feature complete a lean, high-impact design.
Book of Ra is a foundational slot with a devoted following in the United States and across Europe, and continues to attract steady search interest. As the title that launched the “book” sub-genre, its heritage, simple design and the drama of the expanding symbol give it enduring appeal among traditional slot players.
Always play Book of Ra at a casino licensed by a recognised regulator that displays the in-game RTP and offers the official Greentube (Novomatic) version rather than an unbranded clone.
