Book of Ra (especially the Deluxe version) is the legendary slot that established the “Book of” genre. Developed by Novomatic, this game was a massive hit in land-based casinos before its dominance translated to the online world. It is the grandfather of the expanding symbol free spins bonus, featuring a distinct, high-stakes charm and a lower-than-average RTP that players accept for the high reward potential.

🌟 Introduction & Theme
Book of Ra immerses you in the dangerous world of an archaeologist (often dubbed the “Indiana Jones” of slots) searching for ancient Egyptian artifacts. The original Classic version featured retro, almost digital graphics, while Deluxe improved the visual fidelity. The simple, rhythmic electronic sound effects and retro style are instantly recognizable and evoke a feeling of old-school casino thrill. Don’t worry, the protagonist is much better at raiding tombs than he is at dressing for the desert.
⚙️ Gameplay & Special Features
The entire slot’s economy revolves around the Book of Ra symbol, which is the key to both winning in the base game and unlocking the feature.
The Book Symbol (Wild & Scatter)
The Book symbol serves two purposes:
- Wild: It substitutes for all other symbols to create winning paylines.
- Scatter: Landing three or more Book symbols anywhere on the reels triggers the 10 Free Spins bonus.
Free Spins with Expanding Symbol (Key Feature)
This is the feature that spawned thousands of clones, including Book of Dead.
- Initial Spins: You receive 10 Free Spins.
- Symbol Selection: Before the feature starts, one random pay symbol (excluding the Book) is chosen to be the Special Expanding Symbol.
- Expansion Rule: When enough of the Special Expanding Symbol lands on the screen, they automatically expand to cover their entire reel. Crucially, they pay out even if they are not on adjacent reels, provided you land enough of them.
- Re-trigger: Landing three more Book Scatters during the bonus re-triggers the feature, giving you another 10 Free Spins.
Gamble Feature (Optional)
After any base game win, players have the option to enter the Gamble Feature, where they try to guess the color of the next card (Red or Black) to double their winnings.
✅ Verdict and Accessibility
Final Verdict

❓ Frequently Asked Questions
What is the main difference between Classic and Deluxe versions?
Deluxe increased the paylines from 9 to 10 and slightly improved the graphics and sound. Both use the same core expanding symbol mechanic.
What is the highest paying symbol?
The Explorer symbol is the most valuable and can award the 5,000x top prize if it is chosen as the Expanding Symbol and covers all five reels.
Is there a 6-reel version available?
A: Yes! Look for Book of Ra Deluxe 6 on your favorite SA site. It allows you to activate an extra reel for a higher bet, increasing the chance for 6-of-a-kind expansions.
Why is the RTP lower than some other slots?
Because it is a “High Volatility” game with a massive 5,000x single-symbol jackpot. The math is designed to pay out less frequently but in much larger amounts when the bonus hits.
