Introduction
Book of Ra is an Egyptian-themed video slot from Novomatic, and it's the original title that established the expanding-symbol "Book of" format long before later entries like Book of Dead brought the genre to a wider international audience. First popular in land-based arcades and gaming halls before moving online, Book of Ra follows an unnamed explorer searching a pyramid for the treasure of the Egyptian sun god Ra. This review covers exactly how its expanding symbol mechanic works, its RTP and volatility, and what to check before you play it for real money.
Game Overview
Book of Ra runs on a 5-reel, 3-row grid with 9 fixed paylines, one fewer payline than most of its later imitators. Wins are formed by landing matching symbols on consecutive reels along an active payline, starting from the leftmost reel. The mechanic that made the original Book of Ra a hit, and the one every later "Book of" title has borrowed in some form, is a randomly chosen symbol that expands to fill entire reels during free spins.

How Book of Ra Works
Every spin evaluates the 9 fixed paylines for standard matching-symbol wins, a familiar structure for anyone who's played a traditional payline slot before. The signature mechanic sits inside the free spins round: at the start of the feature, one symbol from the paytable is randomly selected to become the expanding special symbol for the entire round. Whenever that chosen symbol lands during a free spin, it expands to cover the whole reel, increasing the chance of forming multiple simultaneous payline wins from a single spin.
Symbols
Low & Mid-Value Symbols
The lower rungs of the paytable use playing-card royals — 9 through Ace — styled to the Egyptian theme, paying modest amounts for landing three or more in a row on an active payline.
High-Value Symbols
Higher up the paytable sit the game's archaeology-themed icons and the explorer character himself as the top standard symbol. Any of these can become the randomly selected expanding symbol at the start of a free spins round, and landing a high-value symbol in that role is the single biggest swing moment in the game.
Scatter Symbol
A dedicated Book scatter symbol doesn't need to land on a payline and instead triggers the free spins round when enough of them appear anywhere on the grid.
Bonus Features
Book of Ra's feature set is built around the expanding special symbol described above, kept deliberately simple in line with the game's original land-based design roots. Many Novomatic builds also include a gamble feature after a win, letting players wager that win on a simple card guess for a chance to double it — a mechanic that predates most modern slots and reflects the game's arcade-machine lineage. Availability of the gamble feature depends on the specific operator and jurisdiction, since some regulated markets restrict or disable it entirely.
Free Spins
Landing 3 or more Book scatter symbols anywhere on the grid triggers 10 free spins. At the very start of the round, one symbol is randomly selected from the paytable to become the expanding special symbol for the entire feature. Landing further scatter symbols during the round can retrigger additional free spins, extending the feature.
RTP
Book of Ra's RTP is commonly cited around 95.10%, slightly below the roughly 96% average for many modern online slots. That's partly a reflection of the game's older design, dating from a period when RTP standards across the industry sat somewhat lower than today's typical range. As with most Novomatic titles, individual casino operators can configure and deploy a different RTP variant of the same game, so the live figure can differ from casino to casino — always check the RTP shown in the in-game paytable before you play. For a deeper explanation of what this number actually measures, see our guide to how RTP works.
Worth checking before you play: RTP figures for the same slot can differ between operators, and older Novomatic titles like this one sometimes ship with several regional variants. Always look at the RTP displayed in the in-game information screen at your specific casino rather than assuming the headline figure applies everywhere.
Volatility
Book of Ra is consistently classified as a high-volatility slot. In practice, that means stretches of small or no wins on the base paylines are common, with the bulk of the game's value concentrated in free spins rounds where the expanding symbol can cover multiple reels at once. If you're not familiar with what volatility changes about how a session feels compared to RTP, our volatility explained guide breaks down the difference.
Maximum Win
Book of Ra's maximum win is commonly cited around 5,000x your total bet, though the exact figure can vary more by market and operator than with more standardised modern releases. That ceiling is reached under a specific, rare combination of events during free spins, when the randomly selected expanding symbol happens to be a high-value icon and lands repeatedly across the reels. Treat it as a theoretical maximum rather than a realistic session expectation.
Betting Limits
The commonly published bet range for Book of Ra runs from $0.01 to $50 per spin (or the equivalent in your casino's currency), a narrower top end than some newer titles in the genre. As with RTP, exact minimum and maximum stakes can be adjusted by individual operators, so treat this as the commonly published range rather than a universal constant, and confirm the limits shown in your casino's own bet panel.
Mobile Compatibility
Book of Ra runs on Novomatic's HTML5 framework in its current online builds, meaning it loads directly in a mobile browser with no separate app download required. Given the game's relatively simple visual design, it performs reliably even on older or lower-spec devices — a meaningful factor for Nigerian players on mobile data connections, though the overall mobile polish trails some of the newer titles covered on this site.
Demo Play
A number of licensed operators that offer Book of Ra also provide a free demo or practice mode, using play credits with no real money involved. That's a reasonable way to get a feel for the payline structure and see how the expanding symbol behaves before staking anything for real. A demo round plays out under the same mechanics as real-money play, though availability of demo mode, and how it's presented, depends on the individual casino rather than being something SpinMirage hosts directly.
How to Play
- Set your stake. All 9 paylines are active by default; check your bet panel to confirm your total stake per spin.
- Spin the reels. Standard wins are paid for matching symbols landing on consecutive reels along an active payline.
- Land 3+ Book scatters. This triggers 10 free spins and reveals which symbol has been randomly chosen to expand.
- Watch for the expanding symbol. Every time it lands during a free spin, it covers the full reel.
- Consider the gamble feature after a win, where available, to risk it on a card guess for a chance to double it.
Tips & Strategy
There's no staking pattern or betting system that changes Book of Ra's underlying RTP or house edge — nothing in this section should be read as a way to beat the game. A few practical habits do make a real difference to how a session feels, though:
- Try the demo first. Because the entire feature hinges on which symbol gets randomly selected, a few free spins in demo mode is a useful way to see the mechanic play out without risking a deposit.
- Set a budget matched to the volatility. High volatility means the base game can run dry for a while between meaningful wins — decide what you're comfortable risking before you start.
- Be mindful of the RTP. At around 95.10%, this figure runs a little below several modern alternatives in the genre — factor that into your session expectations.
- Treat the maximum win as a rare ceiling, not an expected outcome, when deciding how much of a session to plan around chasing it.
Book of Ra vs Book of Ra Deluxe vs Book of Dead
Book of Ra has both an official upgraded sequel and an entire wider genre of imitators. Here's how the original compares to its two closest relatives.
| Spec | Book of Ra | Book of Ra Deluxe | Book of Dead |
|---|---|---|---|
| Provider | Novomatic | Novomatic | Play'n GO |
| Grid | 5x3, 9 Paylines | 5x3, 10 Paylines | 5x3, 10 Paylines |
| RTP | ~95.10% | ~95.10% | 96.21% |
| Volatility | High | High | High |
| Max Win | ~5,000x bet | ~5,000x bet | ~5,000x bet |
| Free Spins Multiplier | None | 3x on expanding symbol wins | None |
The practical difference between the original and the Deluxe version is a single payline and a 3x free spins multiplier, covered in full in our Book of Ra Deluxe review. Compared to Book of Dead, Book of Ra offers a slightly lower published RTP but a longer heritage as the format's true originator.
Responsible Gaming
Book of Ra's high volatility and 5,000x max win ceiling make it a game where session budgeting matters more than usual. Before you play, decide on a fixed amount you're comfortable losing and stop when you reach it, rather than adjusting your budget mid-session to chase a losing streak. Most licensed casinos offer deposit limits, loss limits, and self-exclusion tools — it's worth setting these up in advance rather than relying on willpower alone. If gambling stops feeling like entertainment, free, confidential support is available through BeGambleAware and GamCare. Book of Ra, like every game on SpinMirage, is intended for players aged 18 and over.
Book of Ra in Nigeria
Book of Ra is available at a number of the licensed online casinos accepting Nigerian players, though Novomatic's catalogue is generally less widely distributed in the region than Play'n GO's or Pragmatic Play's. Whether real-money play is available to you, and on what terms, depends on the licensing and payment methods of the specific operator — it's worth confirming a casino is properly licensed before depositing. Book of Ra is also one of several classic-style titles covered in our wider guide to casino games that pay real money in Nigeria, alongside Book of Dead.
Who Should Play This Slot?
Book of Ra suits players who want to try the game that originated the "Book of" genre, and who are comfortable with a slightly lower RTP in exchange for that heritage and a straightforward, no-frills payline structure. It's a strong pick if you appreciate slot history or grew up with Novomatic's land-based machines. If you'd prefer the highest published RTP available in this specific genre, Book of Dead is the better-optimised modern alternative. If you're unsure which volatility band matches your own bankroll and session length, our volatility guide walks through how to make that call.

What is the maximum win on Book of Ra?
Book of Ra's maximum win is commonly cited around 5,000x your total bet.

No. Book of Ra is Novomatic's original release and predates Book of Dead, which is a separate slot from Play'n GO built on a very similar expanding-symbol formula. They share the same general genre and Egyptian theme but are distinct games from different studios with different paytables and specs.
Can I play Book of Ra for real money in Nigeria?

Conclusion
Book of Ra earns its place in slot history as the game that started the entire expanding-symbol "Book of" genre, decades before its many imitators. Its RTP sits a little below today's typical average and its visual design shows its age next to newer titles, but its simple, honest structure and genuine heritage still make it worth trying — especially for players curious where the format everyone else copied actually came from.
