Book of Dead Slot Review: The Complete Play’n GO Guide

The hook is a mechanic Play’n GO borrowed from an older Novomatic classic and refined into something cleaner. Land three or more Book of Dead symbols and you win 10 free spins, but first the game secretly selects one symbol at random to become a special expanding symbol for the entire round. When that chosen symbol lands during the free spins, it stretches to fill the whole reel and pays as if it appeared on every position, even when the copies are not next to each other. If the random pick lands on the explorer himself, the top-paying symbol, a single lucky free-spins run can approach the game’s ceiling of 5,000 times the stake. That one idea is why Book of Dead is a high-volatility slot with an almost cult following.

Every version covered below is built by Play’n GO, and Book of Dead is a video slot wrapped in a classic ancient Egyptian theme. What varies from build to build is not the reels, the symbols or the bonus, all of which are identical, but the return to player figure, because Play’n GO ships Book of Dead in several RTP configurations and lets each operator choose which one to load. That single variable is the most important thing a US player can check before depositing, and it is the reason the version-by-version section below exists for a game that is, on the surface, a single title.

Quick-view table

These headline numbers describe the flagship Book of Dead as Play’n GO ships it in its default, highest-return configuration. Where a value is not published by the studio, it is marked that way rather than guessed. To understand why the return figure matters before you deposit, our RTP explainer is a useful companion.

Version comparison table

Book of Dead is one game, not a family of sequels, so this table maps the thing that actually varies: the RTP build. Play’n GO manufactures Book of Dead in several return configurations and lets the operator pick which one to run, which means two casinos can offer a game that looks identical yet pays very differently. Every build shares the same reels, symbols, bonus and 5,000x ceiling. The only difference is the house edge. Read this before you deposit, and confirm the posted RTP in the game’s information screen.

There is no land-based Book of Dead cabinet in the US market and no bonus-buy edition. Every build in the table is an online HTML5 slot. If a lobby ever labels a Book of Dead machine differently, the difference will be the RTP number in its information panel, never the reels or the bonus.

What Book of Dead is and how it plays

Play’n GO released Book of Dead on January 14, 2016, and it quickly became the studio’s calling card. The setup is deliberately familiar. Rich Wilde, a pulp adventurer modeled on the Indiana Jones archetype, has entered an Egyptian tomb, and the reels are stacked with pharaohs, gods and the ancient book that unlocks the tomb’s riches. The grid is a plain 5-reel, 3-row layout with 10 fixed paylines, and a small toggle lets you pay lines both left to right and right to left, which is one of the few quiet twists in an otherwise classic frame. A new player understands the base game in a single spin.

The base game runs on ordinary line pays with one wrinkle: the Book of Dead symbol is both the wild and the scatter. As a wild it substitutes for every other symbol to complete a line, and as a scatter it pays from anywhere on the screen and unlocks the bonus. Because Book of Dead is a genuinely high-volatility slot, the base game is quiet by design. Wins are modest and often thin, dead spells are common, and the money that makes the game famous almost always arrives in the free spins rather than on the main reels. If you want to size a session correctly, read our guide to volatility first, because Book of Dead punishes an oversized bet faster than a medium-variance slot would.

What keeps the game popular a decade after launch is the combination of that high ceiling and a bonus that can pay all of it at once. The maximum win is 5,000 times the total stake, and unlike many high-variance slots it is genuinely reachable in a single expanded free-spins round rather than only through an improbable stacking of features. The theme helps too: the crackling torchlight, the low chant on the soundtrack and the page-turn animation when scatters land give a plain 10-line slot an atmosphere that far more complex games struggle to match. To browse deposit options across the regulated market, our real money slots hub lists the operators by state.

Symbols

The pay table is short and shared across every build, so learning it once carries you through the whole game. Symbols split into premium Egyptian icons, low-paying card ranks, and the single special symbol that is both wild and scatter. Book of Dead uses a coins-per-line model, and the values below are expressed as multiples of the line bet for a five-of-a-kind win.

High-pay symbols

• Rich Wilde, the explorer: the top standard symbol. Five on a line pay up to 500 times the line bet, the largest regular payout in the game, which is why players hope the random expanding symbol lands on him.
• The golden pharaoh mask, a Tutankhamun-style headdress: the second premium symbol and a strong pay in its own right.
• Anubis, the jackal-headed god: the third premium, paying a solid five-of-a-kind prize.
• The bird god and the scarab: the remaining mid-tier Egyptian icons that fill out the premium pays below Anubis.

Low-pay symbols

• Ace, King, Queen, Jack and Ten: the standard card ranks, carved in stone to match the theme. They fill the reels between the premium hits and pay the smallest amounts.

Wild and scatter

• Book of Dead: the only special symbol, and it does two jobs at once. As a wild it substitutes for every other symbol to help complete a winning line. As a scatter it pays from any position and triggers the free spins, with five Book symbols paying a large scatter multiple of the total stake, four paying less and three paying the entry to the bonus plus a small scatter prize.

Bonus-symbol cross-check

Because players sometimes assume a game with several RTP builds must have several bonus symbols, here is the important consistency check. Every build of Book of Dead uses exactly the same bonus symbol. The Book of Dead is the scatter and the wild in the 96.21 percent build, the 94.25 percent build, the 91.25 percent build, the 87.25 percent build and the 84.18 percent build alike. Nothing about the trigger symbol, the wild behavior or the free-spins mechanic changes between configurations. The only thing that changes is the mathematical return, which is set behind the scenes in the reel weightings and the pay table calibration, not in the symbols you see. So the answer to “do all versions use the same bonus symbol” is a clean yes: one game, one Book, five return settings.

How to trigger the bonus

The trigger is the one rule worth memorizing. Land three, four or five Book of Dead scatter symbols anywhere on the reels and you open the free spins. The Book does not need to sit on a payline, only on the screen. Three scatters award the round and also pay 2 times the total stake, four pay 20 times the total stake, and five pay 200 times the total stake, so the biggest scatter hits are meaningful wins on their own before the free spins even begin. If you are new to the difference between a scatter trigger and a line win, our how to play guide walks through it.

Every trigger awards the same 10 free spins regardless of whether three, four or five scatters landed, which is unusual and worth noting. The round also retriggers: land three or more Book scatters again during the free spins and you win another 10 spins on top, and the retrigger can fire repeatedly, so a single lucky bonus can run far longer than the base 10 games. There is no bonus buy on any build, so the free spins can only be reached by landing the scatters naturally, which rewards patient bankroll play on a high-variance game.

How the bonus works

This is the section that defines Book of Dead, so it is worth walking through exactly what happens on the screen. The moment three scatters land and the 10 free spins are awarded, the game turns to a page in the book and randomly selects one symbol from the pay table to become the special expanding symbol for the entire round. It can be any symbol, from the low-paying Ten all the way up to the explorer. That choice is locked for all 10 spins and it is the single biggest factor in how much the bonus pays.

During the free spins the game plays like the base game with one powerful addition. Whenever the chosen special symbol appears, if there are enough of it on the reels to form or contribute to a win, it expands to cover every position on each reel it touches, and it then pays as though it landed on all three rows of those reels, even across non-adjacent positions. Because the expanding symbol also pays both directions on the 10 lines, a single spin can light up the entire screen. If the random pick was the explorer and he expands across three or four reels late in a retriggered round, that is where the 5,000x maximum win lives. If the pick was a low card rank, the same round can still pay, but the ceiling drops sharply, which is exactly why two identical-looking bonuses on the same machine can end thousands of times apart.

The expanding symbol does not need its copies to be next to each other in the traditional payline sense, which is the mechanic’s defining trick and the reason it feels more generous than a standard stacked wild. The bonus is retriggerable throughout, so scatters landing during the free spins add another 10 spins and keep the same chosen symbol expanding. Outside the free spins, the base game also offers an optional gamble feature after most wins, a card-based guess where you pick red or black to double, or a suit to quadruple, with the option to bank or risk again, though it is disabled in some regulated jurisdictions. There is no wheel, no pick screen and no second bonus. The entire personality of Book of Dead is that one expanding-symbol free-spins round.

Version by version

Book of Dead is a single title, but it ships in five published RTP builds, and for a US player choosing where to deposit that is the whole story. Each build below is the identical game, the same reels, the same Book of Dead scatter and wild, the same 10 free spins with the random expanding symbol, and the same 5,000x ceiling. What changes is the return to player and therefore the house edge. The paragraphs below cover what each build means and how to identify it. If you are weighing where to play, our guide to choosing a slot pairs well with this section, and the practical takeaway is simple: always find the RTP number in the game’s information panel before you spin.

Book of Dead, 96.21 percent build

This is the flagship configuration and the one Play’n GO treats as the default. It returns 96.21 percent, leaving a house edge of 3.79 percent, which is a competitive figure for a high-volatility slot and the reason serious players seek this build out specifically. It carries the full game exactly as designed: 5 reels, 3 rows, 10 fixed paylines that pay both directions, the Book of Dead as combined wild and scatter, and the 10 free spins with one random expanding symbol. The maximum win is 5,000 times the stake. When a review or a casino quotes Book of Dead at “the” RTP, this 96.21 percent number is almost always the one they mean, and it is the build most reputable regulated operators choose to load because a lower return on a game this famous is easy for players to spot and resent.

For US play, this is the configuration to hope for and to verify. Play’n GO distributes Book of Dead to its licensed regulated partners as an online HTML5 game, and a well-run lobby in New Jersey, Pennsylvania, Michigan, Connecticut or West Virginia will typically run the 96.21 percent build. The only way to be certain is to open the game’s information screen, where the live RTP is posted, and confirm the number before depositing. If it reads 96.21 percent, you are playing the game as its designers intended.

Book of Dead, 94.25 percent build

The 94.25 percent build is the identical game with a house edge of 5.75 percent, roughly 2 percentage points worse for the player than the flagship. Nothing visible changes. The reels, the symbols, the expanding-symbol bonus and the 5,000x ceiling are all the same, and the volatility remains high. The difference is baked into the math, so a player cannot see it during a session, only in the long-run return and in the posted RTP figure. This build tends to appear in markets or at operators that choose a lower return setting, and it is the reason checking the information panel matters even on a game as well known as this one. Two players spinning what looks like the same Book of Dead can be facing meaningfully different odds.

Book of Dead, 91.25 percent build

At 91.25 percent the house edge climbs to 8.75 percent, which is a heavy setting for a modern video slot. Again the game itself is unchanged, so the low return is invisible on the reels and detectable only in the game information. A build this low is worth avoiding when a higher one is available, and its existence is the strongest argument for treating the RTP panel as a mandatory pre-spin check rather than a curiosity. On a high-volatility game the swings are already large, and pairing that variance with a sub-92 percent return stretches a bankroll thin. If a lobby only offers Book of Dead at 91.25 percent, a player is often better served by a comparable Egyptian book slot running a higher configuration.

Book of Dead, 87.25 percent build

The 87.25 percent build carries a 12.75 percent house edge, and it exists because Play’n GO lets operators calibrate the game down for certain markets and floor economics. It is the same tomb, the same explorer and the same expanding free spins, but the long-run cost of play is far higher than on the default. There is no reason a value-conscious player would choose this build over the 96.21 percent version if both are available, and it appears here only for completeness and honesty: the game does ship this low. The lesson is the same one this game teaches at every level, which is that the number in the information screen, not the name on the reels, tells you what you are actually playing.

Book of Dead, 84.18 percent build

This is the lowest published configuration, returning 84.18 percent for a house edge of 15.82 percent. It is the same game stripped to its harshest math, and it represents the floor of what Play’n GO publishes for Book of Dead. A return this low on a high-volatility slot is punishing, because the bonus is already rare and the base game already thin, and a build like this compounds both. It is included so that no player assumes every Book of Dead pays the same, because they emphatically do not. In a well-regulated US lobby you are very unlikely to meet this build, but the only way to prove it is to read the posted RTP, which is the single habit this entire section is built to encourage.

Shared specs across all builds

Land-based only

There is nothing to list here, and that is worth stating plainly rather than leaving readers to wonder. Book of Dead was built as an online HTML5 slot and has never shipped as a land-based cabinet in the US regulated market. There is no floor version, no casino-only edition and no separate specification hiding on a physical machine. Every configuration of Book of Dead described on this page is an online game, which keeps the availability picture simple: if you are playing Book of Dead, you are playing it online.

Max win and RTP in context

The maximum win on Book of Dead is 5,000 times the total stake, and it is the same on every build, because Play’n GO adjusts the return through reel weightings and hit frequency rather than by capping the top prize. That ceiling is reached in the free spins when the random expanding symbol is a premium icon, ideally the explorer, and it fills multiple reels across a retriggered round. It is a rare outcome, as any high-volatility maximum is, but it is genuinely a single-round event rather than a theoretical stack of unrelated features, which is part of the game’s enduring appeal.

Return figures are where the honesty of a lobby shows. The default build pays 96.21 percent, which is respectable, but the published range runs all the way down to 84.18 percent, a spread of more than 12 percentage points on what is nominally the same game. No other single number matters more before you deposit. Read the RTP in the information panel every time, because the reels will look identical whether you are getting the best build or the worst. Our random number generator explainer and safety guide cover how certified software keeps those posted figures honest at licensed operators.

Mobile play

Book of Dead was built in HTML5 and runs in the browser on iOS and Android with no separate download. The 10-line grid scales cleanly to a portrait phone screen, the page-turn scatter animation and the expanding-symbol free spins play identically to desktop, and touch controls cover bet selection, line direction, spin and autoplay. Because the game is a plain 5-reel layout rather than a sprawling megaways grid, it is one of the more comfortable slots to play one-handed on a phone. For a broader look at how these titles handle small screens, see our mobile slots guide.

Where to play

Because Play’n GO distributes Book of Dead state by state, the fastest way to find a live version is to start from the regulated operators serving your state rather than the game itself. Our legal sites directory lists the licensed real money casinos by jurisdiction, so you can see which lobby carries Play’n GO and, once inside, confirm the posted RTP build before you deposit. Availability and return settings shift as operators rotate their catalogs, so the in-lobby information screen is always the final word.
