Book of Ra is one of the most iconic slots in land-based and online casino history, originally developed by Novomatic and later adapted digitally via its Greentube branch. Since its introduction, it has spawned countless clones, sequels (“Book of Ra Deluxe”, “Book of Ra Magic”, etc.), and inspired the “Book of” subgenre of slots. Its mix of an Egyptian treasure hunt motif, free spins with expanding symbols, and straightforward structure has made it enduringly popular.

Theme, Visuals & Audio
Theme & Aesthetic
Book of Ra takes place in an Egypt-archaeology motif: hidden tombs, golden books, explorers, sarcophagi, scarabs, and Egyptian deities. The “Book” symbol itself is both wild and scatter—a dual-purpose icon central to the theme’s narrative.
Symbols are richly detailed: golden pharaoh masks, Egyptian gods, ancient books, and classic low card suits stylized as hieroglyphs.
Visual Quality
While originally ported from land-based legacy, digital versions include polished lighting, symbol glows, and a sense of depth via background shifting shadows. During feature triggers, the Book expands and twinkles, adding dramatic flair.
The user interface is minimal: bet controls, spin button, paytable, and gamble overlay are clean and unobtrusive, preserving the archaeological aesthetic.
Audio & Sound Effects
Ambient desert winds, soft percussion, distant echoing Egyptian motifs, and chime cues for wins define the soundscape. When the Book symbol triggers, the music intensifies. Free spin rounds get deeper, mysterious orchestral tones. The audio design supports immersion without overwhelming.
Mechanics & Bonus Features
Payline Structure
Classic versions use 9 fixed paylines, typically left to right, three or more matching symbols on a line produce wins. The Book symbol acts both as a wild (substitute) and a scatter (trigger).
Book (Wild / Scatter) Symbol
The Book symbol can substitute for all regular symbols (when part of a win) and also triggers the free spin when 3+ appear anywhere. In many variants, when the Book acts as scatter, it also awards a scatter payout.
Free Spins with Expanding Symbol
When 3 or more Books appear, a Free Spins mode triggers (commonly 10 free spins). At the moment of trigger, one symbol (excluding Book) is randomly chosen as an expanding symbol. During free spins:
- When the chosen symbol appears in any position on a reel, it expands to fill that entire reel (if possible), increasing chances of large wins.
- Regular symbols on the same line combine with expanded instances to pay across lines.
- The feature may retrigger in some versions (if additional Book scatters land), awarding extra free spins and reapplying expanding logic.
Gamble / Risk Feature
Many land-based-heritage versions and their digital ports include a Gamble option: after a standard win, players may gamble to double or quadruple their payout via a suit-guess or card-guess game. This is optional and carries risk of losing the win.
Mathematical Behavior & Performance
RTP & Payout Profile
The venerable Book of Ra is not designed for high RTP. Classic online versions run around 95.00% – 95.10%, though Deluxe or newer licensed variants may push that to 96%+. The house edge is thus relatively high compared to more modern slot offerings.
Volatility & Hit Patterns
Book of Ra is high volatility. Base-game wins are infrequent and often moderate. The primary payouts occur through the free spins expanding symbol mechanic, making patience essential.
Maximum Win
The standard maximum win is roughly 5,000× stake, typically achieved through expanded symbols during free spins. In deluxe or modern clones, caps may go higher (some versions allow 10,000× or more).
Player Experience & Flow
- Slow build mechanics: Many spins pass with no feature; when free spins trigger, results can be dramatic (especially if multiple expansions align).
- Expanded symbol tension: Watching a symbol expand across a reel is a strong visual reward, especially when it triggers multiple line wins.
- Gamble temptation: The gamble feature draws players who enjoy risk, although it can lead to lost minor wins.
- Nostalgic satisfaction: For many players, the slot feels like a digital heirloom — the “classic Egyptian slot” benchmark many others emulate.
Strategy & Bankroll Guidance
- Use the free demo to estimate how often free spins occur and how expensive the gamble option is.
- Because the base-game is low-rate, allocate a large bankroll relative to your usual stake.
- Resist over-gambling small wins; let free spins drive large payouts.
- If your version includes coin sizing or adjustable payoff schemes, use mid-range stakes to balance frequency and exposure.
Variants & Derivatives
Many versions of Book of Ra exist:
- Book of Ra Deluxe / Deluxe 6: Enhanced visuals, higher caps.
- Book of Ra Magic: Tweaked feature triggers, modified volatility.
- Book of Ra Megaways / “Book of Ra Master”: Some clones adopt Megaways-style reel variation combined with expanding-symbol mechanics.
- Book of Ra Classic (land-based emulator): Direct digital port for nostalgic purists.
Each variant adjusts paytables, volatility, or bonus rules while retaining the core “book expansion” free spin concept.
Demo Access & Real-Money Deployment
A demo version of Book of Ra is widely offered in many online casino lobbies and third-party slot libraries. This allows players to test reel behavior, expansion probability, and free spin pacing.
For real-money play, ensure that you select a casino using the licensed Greentube / Novomatic version (not a clone) to be sure of correct mechanics, certified RNG, and accurate RTP/payout behavior.
Strengths & Weaknesses
Strengths
- Strong brand equity and recognition.
- Simple rules that are easy to understand.
- High impact free spins rounds with expanding symbols.
- Nostalgic appeal for classic slot fans.
Weaknesses
- Lower RTP compared to contemporary titles.

- Some versions can diverge in rules or RTP, confusing players.
Verdict
Book of Ra remains an enduring classic because it combines simplicity with the excitement of expanding-symbol free spins. While its mathematics are less generous than modern titles, its cultural legacy and strong mechanics keep it relevant. For players who enjoy high-risk, high-reward play and have patience for variance, it’s a staple in any slots lineup.

What is Book of Ra?

The game’s success established the entire “Book of” slot subgenre, inspiring hundreds of modern imitations and sequels.
Who developed Book of Ra?
Book of Ra was created by Novomatic, one of the world’s oldest and most influential slot manufacturers. Its digital distribution is managed by Greentube, Novomatic’s online gaming division. Together they ensure that the RNG, payout rates, and game structure mirror the land-based original.
What is the RTP of Book of Ra?
The theoretical return to player (RTP) varies slightly by version and jurisdiction, but most operate between 95.00% and 95.10%. Later variants such as Book of Ra Deluxe and Book of Ra Magic can reach up to 96.00%, depending on operator settings.
Is Book of Ra a high-volatility slot?
Yes. Book of Ra is high volatility, meaning that wins occur less frequently but can be substantial when they do. Most payouts are concentrated within the Free Spins feature, where expanding symbols can cover the entire reel and award multiple line wins simultaneously.
How do you trigger the Free Spins feature in Book of Ra?
The Free Spins feature is triggered by landing three or more Book symbols anywhere on the reels. This awards 10 free spins, and one random symbol (excluding the Book) is selected as an expanding symbol for the round. During free spins, the chosen symbol can expand to fill entire reels, potentially covering all five reels for a maximum win.
What is the maximum win on Book of Ra?
The maximum potential win depends on the version, but the classic edition offers up to 5,000× stake, achievable when five explorer symbols expand across all reels during free spins. Deluxe and later variants sometimes feature higher multipliers or volatility settings, allowing for even larger theoretical payouts.
What does the Book symbol do in Book of Ra?
The Book symbol acts as both a wild and a scatter:
- As a wild, it substitutes for all other symbols to form winning combinations.
- As a scatter, three or more trigger the Free Spins feature.
This dual function makes the Book the single most important symbol in the game.
Can Book of Ra Free Spins retrigger?
Yes. Landing three or more Book symbols during Free Spins retriggers the feature, awarding an additional 10 spins. In some versions (like Book of Ra Magic), retriggers may even add extra expanding symbols, increasing win potential dramatically.
Does Book of Ra have a Gamble feature?
Yes. After any standard win, players can opt for a Gamble feature where they guess the color or suit of a hidden card to double or quadruple their winnings. Incorrect guesses result in losing the staked amount. This feature is optional and designed for entertainment rather than strategy.

It is licensed under multiple regulatory frameworks including the Malta Gaming Authority (MGA), UK Gambling Commission (UKGC), and various European authorities, ensuring compliance and fairness.
