Book of Dead is a Play’n GO slot built around an Ancient Egyptian adventure theme and a single defining mechanic: free spins with an expanding symbol. Almost all of the game’s meaningful win potential is concentrated inside that feature, while the base game often feels like a waiting period between bonus triggers.
Players comfortable with high volatility may appreciate the simplicity and upside potential, but those seeking more frequent rewards are likely to find it repetitive.

Why We Scored this Slot 3.7/5
| Category | Score | Why |
| Gameplay & Mechanics | 3.5 / 5 | The 10-payline, 5×3 grid is clean and easy to follow, but the single-feature structure leaves the base game feeling sparse between bonus triggers. |
| Bonus Features | 4 / 5 | The expanding symbol free spins mechanic is straightforward but genuinely variable — Rich Wilde as the selected symbol produced the most significant returns during testing. |
| Graphics & Soundtrack | 3.5 / 5 | Gold-toned symbols and an Egyptian-themed soundtrack with ambient effects contribute to a presentation that feels considered rather than assembled from stock parts. |
| Mobile Experience | 4 / 5 | The 5×3 grid scaled cleanly to smartphone in landscape orientation, with no control overlap or misfire issues observed during testing. |
| Win Potential & RTP | 3.5 / 5 | The 96.21% default RTP sits fractionally above the industry average, but the 5,000x max win is modest compared to more recent high-volatility releases. |

Book of Dead Slot Overview
Book of Dead is a 5×3 real money slot developed by Play’n GO and released in 2016. It is a clean, uncluttered slot built around a single bonus mechanic that carries most of the weight. The premise follows Rich Wilde, an explorer navigating ancient Egyptian burial chambers.
Visually, it holds up well against more recent releases. Gold-toned symbols, an Egyptian-themed soundtrack with ambient effects during spins, and a considered overall presentation distinguish it from more generic entries in the genre.
The core mechanics are deliberately simple. Ten adjustable paylines run across the 5×3 grid, wins require at least three matching symbols on an active line, and the entire bonus structure rests on one feature: free spins with an expanding symbol. There are no cascading reels, no multiplier trails, no bonus-buy option.
This slot suits players who are comfortable with high variance and don’t need a steady stream of small wins to stay engaged. If you’re looking for a feature-rich slot with frequent interaction, Book of Dead will likely feel sparse.
Technical Breakdown
RTP and return mechanics
Book of Dead carries a published RTP of 96.21%, which sits fractionally above the working industry average of around 96%. In practical terms, the game is designed to return approximately $96.21 for every $100 wagered over a very large number of spins — that figure says nothing useful about any individual session.
Play’n GO allows operators to configure RTP settings on some of their titles. The operator-configured RTP range for this specific version has not been independently confirmed. Always verify the RTP in the in-game paytable before depositing.
Given the high volatility, actual returns during a given session can deviate significantly in either direction. The 96.21% figure represents the default published rate for this configuration.
Volatility and session feel
During testing, the balance moved in a pattern consistent with the high-volatility classification. Small wins from the royal card symbols landed occasionally but rarely covered the cost of the spin.
The premium symbols — Horus, Anubis, Osiris, and Rich Wilde — appeared infrequently enough that most spins returned nothing meaningful. The net effect was a gradual, steady drain on the balance between bonus triggers, punctuated by occasional line hits that partially offset losses without reversing them.
The free spins feature was the only point where the session dynamic shifted noticeably. Outside of that feature, the base game felt like a slow accumulation of small losses with intermittent partial recoveries. Due to high volatility, expect extended dry spells between significant wins — manage your session budget accordingly.
Bonus features
Book of Dead’s bonus structure is built around three mechanics:
- Wild: The Book symbol substitutes for any paying symbol in a line combination. It appeared with moderate frequency during testing, though its impact in the base game was limited to completing occasional line wins.
- Scatter pays: Three or more Book symbols landing anywhere on the reels award scatter pays independently of paylines and trigger the free spins feature.
- Free Spins: Landing three or more Book symbols triggers 10 free spins. Before the round begins, one symbol is randomly selected to act as an expanding symbol throughout the feature — when it appears on any reel, it expands to fill the entire reel and pays across all positions, not just active paylines. The feature can re-trigger if three or more Books land during the spins.
- Gamble Feature: After any base-game win, players can guess the colour or suit of a face-down card. A correct colour guess doubles the win; a correct suit guess quadruples it. A wrong guess forfeits the win entirely.
In testing, triggering the free spins feature required patience — it did not arrive frequently. When it did trigger, the value of the round depended almost entirely on which symbol was selected and how often it appeared. Rich Wilde as the expanding symbol produced the most significant returns, given his position at the top of the paytable.
Re-triggers were rare during testing but did occur. A re-trigger during a round where the expanding symbol is performing well can extend the return significantly.
The gamble feature carries meaningful risk in the context of this slot. Because base-game wins are already infrequent, losing a hard-won line payout to a failed guess has a noticeable effect on session balance.
Graphics and soundtrack
The visual presentation is polished for a 2016 release and holds up against more recent titles. Gold-toned symbol design, clean reel animations, and an Egyptian-themed soundtrack with ambient effects during spins all contribute to a coherent atmosphere.
The presentation feels considered rather than assembled from stock parts, which is notable given the age of the release. There is no visual clutter — the single-feature structure is reflected in the interface design.
Mobile Performance
Book of Dead was tested on a smartphone in landscape orientation. The 5×3 grid scaled cleanly to the screen, and the control buttons — spin, bet adjustment, and autoplay — were sized adequately for touch input without any overlap or misfire issues.
Visual quality held up without any obvious compression or frame-rate degradation compared to the desktop version. The game appeared to be natively optimised for mobile rather than adapted after the fact, which is consistent with Play’n GO’s general approach to mobile delivery.
Pros and Cons
| Pros | Cons |

| Clean mobile layout with no usability issues on smartphone | Maximum win of 5,000x is modest compared to more recent high-volatility slots |
| Simple 10-payline structure is easy to track and understand | Free spins trigger infrequently; patience and session budget management are required |
| Gamble feature offers a meaningful optional risk layer | Gamble feature can erase rare base-game wins entirely if misjudged |
Who Is This Slot For?
Book of Dead suits players who are specifically looking for a high-variance slot with a straightforward structure and are comfortable managing a session budget through extended periods without meaningful returns.
It is less well-suited to:
- Players who need regular small wins to stay engaged — the base game will feel sparse
- Those working with limited session budgets — high volatility means the feature may not trigger before the balance is depleted
- Players expecting feature depth — there is one bonus mechanic and no secondary paths to wins
- Players weighing max win potential — the 5,000x ceiling is lower than many comparable high-variance releases available on real money online slots platforms
Where to Play
Play’n GO slots are almost everywhere these days. However, I chose to play at Ninlay Casino, whose streamlined platform ensures smooth Book of Dead gameplay. This casino is also home to dozens of Play’n GO slots, including trending titles like Moon Princess, Reactoonz, and Legacy of Dead.
A Note on Responsible Gambling
Book of Dead is a high-volatility slot. The single-feature structure means the base game can run through extended stretches of near-zero returns before the expanding symbol free spins round arrives — and that round is not guaranteed to perform when it does trigger.
- Set a session budget before you start and treat it as an entertainment cost, not a recovery target
- The gamble feature can eliminate a hard-won base-game win in a single incorrect guess — use it only if you are comfortable losing the win entirely
- Use your casino’s deposit limits, session timers, and self-exclusion tools if your play feels compulsive
- Each spin carries the same probability regardless of previous results — there is no mechanical tendency for a bonus to arrive after a dry spell
- Free support is available across Canada: ConnexOntario 1-866-531-2600 · BCLC GameSense 1-888-795-6111 · AGLC GameSense (Alberta) · ccsa.ca

Similar Slots You Might Enjoy
If Book of Dead’s expanding symbol mechanic appeals to you, the following titles share structural similarities and are worth comparing:
- Legacy of Dead — Play’n GO’s Egyptian sequel uses the same expanding symbol free spins framework with some structural differences worth examining before you choose between them.
- Book of Ra — The Novomatic classic that established the book-slot format. The core gameplay loop is comparable to Book of Dead, which is likely why players familiar with one tend to migrate to the other.
- Blood Suckers — A NetEnt slot with a notably higher published RTP, useful as a point of comparison for players who weigh return rate heavily when choosing high-volatility titles.
FAQ
How often does the free spins feature trigger in Book of Dead?
The free spins feature requires three or more Book symbols to land anywhere on the reels simultaneously. Triggers were infrequent during testing and required sustained play to encounter. There is no published hit-frequency figure for the feature, but the high volatility classification is consistent with a bonus that arrives less often than in medium or low-variance slots.
What does the expanding symbol mechanic do during free spins?
Before the free spins round begins, one symbol is randomly selected to act as an expanding symbol. When that symbol appears on any reel during the 10 spins, it expands to fill the entire reel and pays across all positions — not just active paylines. The outcome of the feature is largely determined by which symbol is chosen and how often it lands, making it genuinely variable from one trigger to the next.
Is the gamble feature worth using?
The gamble feature carries real risk in the context of this slot. Because base-game wins are infrequent due to high volatility, losing a line win to a failed colour or suit guess has a noticeable effect on session balance. Whether to use it depends on individual risk tolerance, but in a game where wins are already sparse, approaching it cautiously makes sense.
How does Book of Dead compare to Book of Ra?
Both slots share Egyptian themes and a similar expanding-symbol free spins mechanic, but Book of Dead was released later and reflects a more polished visual standard. The published RTP for Book of Dead is 96.21%; Book of Ra’s RTP varies by version and operator configuration, so direct comparison requires checking the specific variant available at your casino. The core gameplay loop is comparable, which is why players familiar with one tend to migrate to the other.
Can the free spins feature re-trigger?
Yes. If three or more Book symbols land during the free spins round, the feature re-triggers and awards an additional 10 spins. Re-triggers were rare during testing but did occur. A re-trigger during a round where the expanding symbol is performing well can extend the return significantly.
Is Book of Dead available on mobile?
Yes. The game was tested on a smartphone in landscape orientation and performed without usability issues. The grid scaled cleanly, controls were well-sized for touch input, and visual quality was consistent with the desktop version.
