Book of Dead by Play'n GO is an Egyptian-themed video slot that was released in 2016 and has become one of the most recognizable titles in the online casino industry over the past decade. RTP 96.21%, high volatility, 5x3 grid with 10 paylines and a maximum win of x5,000 of the bet. Key mechanic - Expanding Special Symbol in the Free Spins round: one randomly selected symbol expands to all reel lines and awards a payout for each line separately. The player takes on the role of Rich Wild - an adventurer searching for artifacts in Egyptian tombs. You can play Book of Dead demo for free without registration on the official Play'n GO website and most aggregator sites.
Quick verdict
Book of Dead is not just a popular slot. It is the archetype of an entire subgenre, called “book slots” by analogy with the mechanics of a special book as Wild and Scatter at the same time. After its release in 2016, the game set a standard that dozens of titles from different providers followed.
What sets the original apart from its many imitators? A balance between simplicity and depth. The Expanding Special Symbol mechanic is one of the most straightforward in the slot industry: one symbol, one round, one question - what will it be? The mathematical range of results is enormous: Expanding Special Symbol on a cheap card symbol gives a minimal payout, on Rich Wilde when covering all five reels - a potentially transformative payout.
The RTP of 96.21% is one of the highest base return rates among slots with a comparable volatility profile. But check with your operator for the specific version: Play'n GO gives casinos the option to set lower RTP options - 94.25%, 91.25% and others. The difference between the base and minimum version is significant in the long run.
For new players in the high-volatility slot category, Book of Dead is a smart starting point: the mechanics are transparent, the potential is real, and thousands of real player sessions provide a rich array of statistical benchmarks.
WinAssist rating: 8.6/10— a classic with proven mathematics and understandable mechanics; minus for the lack of an official Bonus Buy and dependence on one symbol in Free Spins

Play'n GO is a Swedish provider with licenses from MGA, UKGC and a number of other regulators. Book of Dead is part of the Rich Wilde series - a line of titles with the same name character: Tome of Madness, Amulet of Dead, Shield of Athena and others. Each subsequent game in the series complicates the mechanics, but the original remains the most famous and quoted of all.
How the game works - symbols and basic mechanics
Grid and paylines
The standard 5x3 configuration with 10 fixed paylines is one of the most classic in video slots. Payouts are calculated from left to right when 3, 4 or 5 identical symbols appear on adjacent reels, starting from the first one. No cluster mechanics, no cascading tumbles - pure classic video slot with one exception in the form of the Expanding Special Symbol in Free Spins.
The bet per spin covers all 10 lines at once. The number of active lines is not adjustable by the player - only the coin size and the number of coins per line determine the total bet per spin.
Symbols and their value
Rich Wilde— the main character and the most valuable premium symbol. With 5 of the same on a payline, it gives the maximum linear payout in the base game.
Egyptian Pharaoh— the second most valuable premium symbol. Together with Rich Wilde, it forms the basis of potential big payouts.
Statue of Anubis, Scarab, Lotus— middle row of symbols by payouts. Gives certain payouts in the base game, but the real potential is revealed in Free Spins when it appears as an Expanding Special Symbol.
Card symbols J, Q, K, A— basic symbols with minimal payouts. When they land in the role of the Expanding Special Symbol in Free Spins, they give minimal compensation and rarely justify the spins spent.
Book— a unique symbol with a dual function:
- Works likeWild— replaces any symbol except another Book when forming winning combinations
- Works likeScatter— 3+ Books in any position on the screen trigger Free Spins regardless of paylines
- The combination of Wild and Scatter in one symbol is a defining feature of the entire "book genre"
The total number of symbols is small, which is a conscious design decision: the fewer symbol types, the higher the likelihood of large clusters forming. In Book of Dead, this principle is taken to its logical conclusion through the Expanding Special Symbol, a mechanic that makes one symbol temporarily dominant.
Free Spins mechanics are the heart of the game
Trigger and Expanding Special Symbol
Free Spins are triggered when 3 or more Book symbols appear in any position on the reels - regardless of paylines. This is standard scatter logic: the position of the symbols does not matter, only the total number on the screen is important.
Award:10 free spins.
Before the start of the round, the systemrandomly selects one characterfrom the general list as Expanding Special Symbol. The selection is displayed on the screen with an animation - the player sees which symbol has become special.
Key mechanics Expanding Special Symbol: if the selected symbol appears on any reel during a spin in Free Spins, itexpands to all three linesof this reel. The payout is calculated foreach lineseparately, even if the character originally occupied only one position.
Terminological accuracy is important:Expanding Special Symbol is not Wild. Book remains a Wild symbol. Expanding Special Symbol is a separate role that one of the regular symbols takes on exclusively during the Free Spins round. These two roles do not overlap.
Mathematics Expanding Special Symbol
The payout potential depends on two factors: which symbol is chosen and how many reels it appears on.
When Expanding Special Symbol onRich Wildeand coverageall five drums: each reel expands to three rows, Rich Wilde actually fills the entire screen. The payout is calculated on 10 paylines with 5 Rich Wilde on each - this is the maximum of the game, x5,000 of the bet.
When Expanding Special Symbol oncard symbol (A, K)Even if you cover all five reels, the payout will be significantly lower - card symbols have the lowest linear payout coefficients. This is where all the volatility lies: the range from "nothing" to "maximum" is determined in the first seconds of the round when a special symbol is selected.
Statistically, the probability of a particular symbol becoming an Expanding Special Symbol is uniform across all symbols — but the payout ratios between Rich Wilde and the card symbol A differ by a factor of several.
Retrigger
3 or more Book symbols during an active Free Spins round awardextra 10 spins. The Expanding Special Symbol does not change during retriggering - the same symbol remains special until the end of the entire expanded round. This is important: if the symbol is Rich Wilde and a retrigger occurs - another 10 spins with the same potential.
Theoretically, the number of retriggerings is unlimited. In practice, long retrigger chains are rare, but they form the majority of record payouts in the game.
Bonus Features and Bonus Buy
No Bonus Buy in the basic version
The original Book of Dead from Play'n GO does not have an official Bonus Buy— this is a fundamental difference from many modern high-volatility titles, where bonus buys are a standard option. If a specific operator or platform offers Bonus Buy for Book of Dead, it is a custom or modified version, not the basic mechanics from the provider.
For players who value the ability to buy a bonus round, this is a significant limitation. For those who avoid Bonus Buy for budget reasons, the lack of this option simplifies bankroll management.
A comparative review of slots with a similar Egyptian style and a wider range of modern features is in the article about Olympus Blessing by Pragmatic Play, which details the mechanics of the new generation provider.
Ante Bet
An Ante Bet feature is available on some versions and platforms. It increases your bet by a certain percentage in exchange for an increased chance of Book symbols appearing in the base game, which speeds up your entry into Free Spins. Ante Bet availability and terms vary by operator and version - please check before playing for real money.
RTP and volatility - what is important to know before the first spin
Three versions of RTP: what does the operator choose?
The base RTP of 96.21% is the highest available for Book of Dead. However, Play'n GO gives operators the option to set lower versions: 94.25%, 91.25% and potentially other configurations. The specific RTP version in effect at your casino is usually listed in the game rules in the appropriate section - the "i" or "?" button inside the game interface.
The difference between 96.21% and 91.25% is significant in the long run. With $10,000 in total bets, the theoretical difference in return between the two versions is ~$496. Checking the RTP before playing is a basic procedure that is often ignored.
Volatility profile: dry series as the norm
Book of Dead is a high volatility game, where the vast majority of base game spins either pay out nothing or only return a portion of the bet. The payout distribution is skewed towards rare but significant events - primarily the Free Spins round with a successful Expanding Special Symbol.
A dry streak without Free Spins lasting 200 or more spins is typical, not abnormal for this profile. When planning your bankroll, consider the possibility of a long wait without significant income. A comfortable bankroll for organic play is approximately 200–300 bets per spin. This is a subjective assessment, not an official parameter from the provider.
The Rich Wilde series and the place of the Book of Dead in it
Book of Dead was the first and still the most recognizable title in the Rich Wilde series from Play'n GO. After 2016, the provider expanded the series with several sequels: Tome of Madness, Amulet of Dead, Shield of Athena and others. Each game in the series introduces new or more complicated mechanics while maintaining the character.
The original remains a starting point for getting to know the series due to its simple architecture and straightforward mechanics. For players already familiar with Book of Dead and looking for more complex titles with higher potential, subsequent games in the series provide an evolutionary complication without jumping into radically different mechanics.
Comparison with analogues and niche of the game
Book of Dead belongs to the “book slots” genre, a broad category of titles that use a similar architecture: book as Wild/Scatter, 10 free spins, Expanding Special Symbol. Novomatic’s Book of Ra is an earlier representative of the concept, but focused on offline casinos and Flash environments. Book of Dead has adapted and reimagined this concept for modern HTML5 platforms.
| Parameter | Book of Dead | Book of Ra Deluxe | Amulet of Dead |
| Provider | Play'n GO | Novomatic | Play'n GO |
| RTP | 96.21% | 95.1% | 96.26% |
| Volatility | High | High | High |
| Max Win | x5,000 | x5,000 | x5,000 |
| Net | 5×3 / 10 pay | 5×3 / 10 pay | 5×3 / 10 pay |

Bankroll Management in Book of Dead
No bankroll management approach affects the RTP and the game's built-in math. Everything below is a guideline for spending pace and psychological comfort during a session, not a method to increase your chances of winning. Play only with the amounts you are willing to spend.
Bet size relative to bankroll
A standard recommendation for high-volatility slots is to bet per spin within 0.5–1% of your total gaming budget. With a $100 budget and a $0.50 bet, that's 200 spins — enough to statistically expect a few Free Spins entries under a normal distribution.
With a bet of $1.00 and the same budget, 100 spins is the bare minimum for any representative result. With a smaller supply of spins, the discrepancy between the expected and actual result can be dramatic.
What to do during Free Spins
The Free Spins round is the only point where the main potential of the game is concentrated. It is important to remember: after the Expanding Special Symbol is announced, the outcome is actually determined in terms of range - you know which symbol will expand, and you understand the possible maximum.
If the symbol chosen is Rich Wilde or Pharaoh, the mathematical potential of the round is significantly higher. If the chosen card symbol (A, K, Q, J) is selected, the actual expected win is significantly lower even when covering all five reels.
Organic game without Bonus Buy
Since there is no Bonus Buy in the base version, the only way to get to Free Spins is to wait organically. This means that your bankroll should be large enough to cover dry spells between rounds. Try not to increase your bet after a series of losing spins - a classic "wagering" trap that doesn't affect the math but accelerates bankroll depletion.

Mobile version and demo
Book of Dead is developed on HTML5 - full compatibility with any mobile device without downloading applications. Play'n GO traditionally pays priority attention to mobile optimization: the Expanding Special Symbol animation and the bet management interface are correctly displayed on smartphones with a screen of 5 inches or larger.
You can play Book of Dead demo for free on the official Play'n GO website and on most aggregator platforms without registration. The demo mode provides full functionality of the base game and Free Spins - no restrictions compared to the real mode, except for the lack of real payouts.
Practical advice for new players: in the demo, record which symbol becomes the Expanding Special Symbol in each of the Free Spins rounds played and the corresponding win. After 5–10 rounds, you will get a real feel for the range of results and the frequency of "lucky" vs. "unlucky" symbols.

Pros and cons of Book of Dead
Advantages:
RTP 96.21% in the base version— one of the highest rates among high-volatility slots with a comparable profile. This is a real advantage that the player feels in the long term.
Understandable Free Spins mechanics— Expanding Special Symbol is clear and transparent. Once the symbol is announced, the player understands the range of possible outcomes without hidden layers. The absence of multipliers, cascades, and additional mechanics makes it easier to assess the situation.
Retrigger without limits— theoretically, a retrigger chain can last indefinitely, although in practice long chains are rare. But the possibility itself significantly increases the mathematical potential of the round.
A proven title with a large statistical sample— nearly a decade of real-world session data from millions of players. Game behavior is well documented and validated.
Wide range of rates— from $0.10 to $100 per spin, covering an audience from casual to high rollers.
The downside:
Depends on the choice of Expanding Special Symbol— if a card symbol is chosen, even with a retrigger, the real value of the round is minimal. This random variable is both a source of tension and a source of disappointment.
No Bonus Buy in the basic version— for players who prefer controlled entry into the bonus, this is a fundamental limitation. Organic waiting for Free Spins requires sufficient bankroll and time.
Reduced versions of RTP from some operators— without prior verification, a player can play at 91.25% RTP, thinking that he is getting 96.21%. The responsibility for verification lies with the player.
Lack of modern mechanics— unlike the titles of 2020–2024, Book of Dead does not have multipliers in the base game, stacking multipliers, hold & respin or other mechanics that have become standard. For players who appreciate more complex game systems, this is a limitation. For those looking for a classic, it is an advantage.

FAQ — frequently asked questions
How is Book of Dead different from Book of Ra?
Book of Ra by Novomatic is an earlier title that established the classic “book slot” concept. Book of Dead by Play'n GO was released later and represents a modern reinterpretation of that idea for online platforms.
It is built on HTML5 technology, features a slightly higher base RTP, and uses a different visual style while maintaining a similar core mechanics structure. The two games are not officially connected — they are separate products from different providers.
What is the Expanding Special Symbol and why is it important?
At the beginning of each Free Spins round, the game randomly selects one symbol to become the Special Symbol.
If this symbol appears during the bonus round, it expands to fill the entire reel (all three rows), and payouts are calculated for each active payline.
This mechanic creates the potential for the maximum win of x5,000, especially when the Rich Wilde symbol becomes the Special Symbol and appears across all five reels.
Does Book of Dead have a Bonus Buy?
In the standard version of the game by Play'n GO, there is no Bonus Buy feature.
Some casinos or aggregator platforms may provide modified versions with a bonus purchase option, but this is not part of the original game design.
How can I check the RTP at a specific casino?
Open the game inside the casino and locate the “i”, “?”, or “Rules” button in the interface.
The RTP value is usually displayed in the RTP or Paytable section. If it is not visible, it is advisable to contact the casino’s support team before placing real-money bets.
How many spins are needed to trigger Free Spins?
The official trigger frequency for Free Spins is not disclosed by the provider.
Based on aggregator data and community statistics, the estimated average is around one bonus every 150–250 spins, although this is not guaranteed and variance can be significant.
Streaks of 300 or more spins without triggering the bonus are statistically normal for a slot with this volatility profile.
Is Book of Dead available in licensed casinos in Ukraine?
Yes, Book of Dead is available with KRAIL-licensed operators that offer Play'n GO content.
Before playing with real money, it is recommended to verify the availability of the game in the casino’s catalog and check the RTP version configured by the operator.
Summary - for whom Book of Dead is the right choice
Book of Dead is not a new game. But almost a decade of market presence and the status of an archetype of an entire genre is a confirmation that does not need marketing reinforcement.
The game is suitable for:players looking for a high-volatility title with transparent mechanics and a confirmed RTP of 96.21%; those who are prepared to wait a long time for Free Spins without the ability to buy a bonus; new players in the high-volatility category looking for a clear entry point without complicated accumulation mechanics.
The game is less suitable for:those for whom Bonus Buy is a must-have feature; players who prefer titles with multipliers in the base game or cascading mechanics; those looking for a max win above x5,000 of the bet.
Before choosing a casino, check the RTP version - the difference between 96.21% and 91.25% is fundamental for any regular gaming budget.
