Book of Dead slot by Play'n GO — game artwork

The Book of Dead demo is the free, no-signup version of the 2016 Play’n GO slot that made the book format a genre. Ten paylines, one bonus round, and a randomly chosen expanding symbol that decides whether ten free spins pay pennies or 5,000× your stake. Play it free here, then read the RTP section before you ever play it for money — this game is sold at five different return levels.

The Book of Dead demo runs the real game with play money: same reels, same free spins, same maths as the build the demo server is running. There is nothing to install, no account and no deposit. As a result it is the cheapest way to find out whether ten paylines and a single feature hold your attention for an hour, which is the honest question about this game.

This demo is part of our Play’n GO demo collection.

JackpotNoneNo jackpot, fixed or progressive. Nothing is taken out of your stake to feed a pool — everything the game pays comes out of the paytable and the free spins.

How the game plays

Book of Dead is a five-reel, three-row slot with ten paylines, and it is deliberately old-fashioned. There is no cascade, no multiplier trail and no second screen. You spin, you line up Rich Wilde and a row of Egyptian icons from the left, and you wait for three golden books.

The free spins are the whole game

Everything this slot has to give sits in one round. Land three or more Book of Dead scatters anywhere on the reels and you get ten free spins. Before the round starts, the game randomly picks one ordinary symbol and promotes it to a Special Expanding Symbol for the whole sequence. When it lands during a free spin, after any normal win has been paid, it expands to fill all three positions on its reel. Crucially, Play’n GO’s own rules state that expanded symbols do not need to be adjacent to each other to form a win. That is why a single expanded symbol can pay across reels one, three and five while the rest of the screen looks like nothing happened.

Land three or more scatters again inside the round and it re-triggers, adding another ten free spins. No cap is advertised, so re-triggers stacking on a high-value expanding pick are where every big Book of Dead clip you have ever seen comes from.

One symbol doing two jobs

The book itself is the scatter that opens the round and the wild that substitutes in normal play. Because one symbol does both, the format is unusually cheap to build and unusually tense to play, and almost every studio now has a copy of it in the catalogue.

The story behind the game

Play’n GO released Book of Dead on 14 January 2016, and the studio still dates it on its own game page. It is the second Rich Wilde adventure: after the Pearls of India and a run-in with Aztec idols, the explorer lands in Egypt.

The format was not new — Novomatic’s Book of Ra had been running in arcades for a decade — but Book of Dead is the game that moved it online at scale. It became the default free-spins offer for half the casino industry, which is exactly why it is worth being careful about which version you are playing. A game handed out in hundreds of thousands of bonus spins is a game operators have a reason to run at a cheaper setting.

Ten years on it still ranks in SlotCatalog’s top few hundred games worldwide, on a mechanic the studio has since rebuilt more than a dozen times — Legacy of Dead being the closest and, in most lobbies, the better-placed successor.

Symbols and paytable

One detail matters more than any individual symbol value: Play’n GO’s paytable displays wins per line bet, not per total stake. With ten lines in play, a figure on that screen is a tenth of what it looks like next to the number in your balance. Here is what the game is actually made of.

The Book — scatter and wild in one symbolThree or more anywhere on the reels start ten free spins, and the same symbol substitutes for everything else during normal play. Official, on Play’n GO’s own page.
The Special Expanding SymbolChosen at random before the round begins, for the whole round. It expands over all three positions of its reel once regular wins are paid, and expanded symbols do not have to touch each other to pay.
Ten paylines, left to rightSlotCatalog records ten paylines and five reels; the official page states no payline count at all. Fixed lines mean every spin buys the same board.
The re-triggerThree or more scatters during the free spins award another ten free spins, and the same expanding symbol carries through.
Bet range0.01 to 50 per spin, per SlotCatalog. That is a spread wide enough for both a coffee-money session and a stake most bonus terms would void.
TechnologyHTML5 and JavaScript, 7.8 MB, built to run in a phone browser. No download exists and none is needed.

What is not in the paytable is a single multiplier, buy-in, or side bet. Whatever Book of Dead pays you, it paid through ten lines and one round of free spins.

Bonus features and free spins

📖

The Book is scatter and wild

Three or more open the free spins; the same symbol substitutes for any other in the base game. One symbol, two jobs — the mechanic every “book” slot since has copied.

✨

Ten free spins, one expanding symbol

A symbol is drawn at random before the round and expands across its whole reel whenever it can add a win. Draw Rich Wilde and the round can run into thousands of times your stake; draw the ten and it mostly cannot.

🔄

Re-triggers, stacking

Three more scatters inside the round add another ten spins, keeping the same expanding pick. Two re-triggers on a premium symbol is the shape of every huge win this game has produced.

🃏

Gamble: double or quadruple

After any win you can press gamble and guess a card. Colour doubles it; suit pays four times. Guess wrong and the win is gone. SlotCatalog lists it as a Risk (Double) game.

⚠

Five RTP builds

The same game is certified from 84.18% to 96.21% and the operator picks. This is a feature of the product whether you like it or not, and it is worth more to you than any symbol value.

The gamble feature, properly explained

Every win in the base game can be sent to the gamble screen. Guess the colour of the next card and the win doubles; guess the suit and it quadruples. Guess wrong and it is gone. SlotCatalog lists the feature as a Risk (Double) game, and Play’n GO does not publish its odds.

The maths is not complicated. A colour guess is roughly a coin flip and a suit guess roughly one in four, so the feature is close to break-even before you account for the fact that it turns a real win into a possible zero. On a high-volatility game where the free spins may only arrive once an hour, gambling the round’s payout is the fastest way to turn a good session into a blank one.

What we like

  • A genuinely great free-spins round: one random pick decides the whole session, and the tension is real every time
  • 96.21% on the top build is a fair number for a game of this age
  • Expanded symbols pay without being adjacent, which turns quiet-looking spins into wins
  • Re-triggers have no advertised ceiling, so the good rounds have room to run
  • Playable free here with no signup, and it plays identically on a phone
What to watch

  • Five certified RTP builds, down to 84.18% — you cannot know which one a casino runs without opening the info screen
  • One feature and nothing else: no multipliers, no modifiers, no second bonus in ten years
  • High volatility with ten paylines means long, flat stretches between rounds
  • Play’n GO publishes no RTP, volatility or max win itself, so every figure here comes from databases rather than the studio

How Book of Dead compares

Book of Dead is not the only book slot we have reviewed, and it is no longer Play’n GO’s best-placed one. Here is how it sits against the studio’s other games in our library, using each game’s own verified numbers.

GameRTPLayoutVolatilityCeiling
Book of Dead96.21% top build, five builds down to 84.18%5×3, 10 linesHigh5,000×

Fire Joker94.23%3×3, 5 linesMedium800×
GemixNo studio figureCluster pays, no linesMedium6,025×

Legacy of Dead is the same idea built four years later and, in most lobbies, placed better. Fire Joker is the opposite game — small, quick, medium volatility, a ceiling you can actually reach. If what you want is the book round, Book of Dead is the original and the free demo above costs nothing to try; if you want variety inside a session, neither book game will give it to you.

Book of Dead RTP, volatility and max win

Book of Dead is published at more than one RTP. Play’n GO certifies this game at five return levels and the casino chooses which one it runs. SlotCatalog lists all five. Nothing on the reels changes, the paytable looks identical, and the only place the figure appears is the game’s own information screen — which is why the first thing this review tells you to do is open it.

96.21%The highest certified build, and the figure most sites quote as “the” Book of Dead RTP.
94.25%The build SlotCatalog records in its own attributes panel — a full two points below the headline.
91.25%Roughly 9× the house edge of the top build.
87.25%Found in low-RTP markets and at some operators.
84.18%The floor. Nearly four times the house edge of the version the internet advertises.

The number everyone quotes is 96.21%, and on the top build it is accurate. That is a house edge of 3.79%, which for a 2016 game is a fair deal and better than plenty of 2026 releases.

Five builds, one set of reels

The problem is the word “build”. Play’n GO certifies Book of Dead at five return levels, and the casino chooses which one it deploys. SlotCatalog’s attributes panel for this game does not record 96.21% at all — it records 94.25%. Two points of RTP is not a rounding difference: on €1,000 of turnover it is €38 of expected loss instead of €20. At the 84.18% floor, the same turnover expects to cost you €158.

There is exactly one way to know which build you are on, however. Open the game’s information screen at the casino you are playing and read the RTP it states there. It takes ten seconds and it is worth more than every strategy article ever written about this game. If that screen does not state a figure, then that is an answer too.

Volatility and the ceiling

The volatility is high, confirmed by both databases we checked, and the shape of the game explains why. Because there are ten paylines and a single bonus round, your balance drifts down through the base game while the free spins carry the session, so expect long gaps between them. The recorded ceiling is 5,000× your total bet, reachable only through a high-value expanding symbol plus re-triggers, which is rare by design. Play’n GO publishes none of these numbers itself — its official game page states the release date and the free-spins rules and stops there.

Bets, bankroll and session planning

Stakes run from 0.01 to 50 per spin, so the same game serves a 10-cent session and a table-stakes one. With ten fixed lines there is no bet-level decision to make beyond the total: you are always buying the same board.

High volatility on a one-feature game has a practical consequence. The free spins are the whole return, so a bankroll that cannot survive a few hundred spins without one is a bankroll that will end its session before the game has had a chance to do the only thing it does. A common rule of thumb is a stake no larger than a two-hundredth of what you are prepared to lose in the session.

If you are clearing a bonus on this game, check the maximum bet rule in the casino’s terms first. Book of Dead is one of the most commonly offered free-spins games in the industry, and going over the cap while bonus funds are live is the most common way winnings get voided. Our casino bonuses page has a calculator that shows what those terms actually cost.

Playing on mobile

The game is HTML5 and JavaScript, about 7.8 MB, and it was built for touch. The reels fill a portrait screen, the gamble ladder works with a thumb, and nothing needs installing — the Book of Dead demo above opens straight in the phone browser you are reading this on.

The one thing a phone makes easier to miss is the information screen, because it sits behind the menu rather than on the main view. On a game with five RTP builds, however, that is the screen worth finding.

Five things to know before you spin

  1. Open the casino’s in-game information screen and read the RTP before your first real spin — five builds exist and only that screen tells you which one you have.
  2. Remember the paytable shows wins per line bet. Divide by ten to compare it with the number in your balance.
  3. The expanding symbol is drawn before the round starts, not during it. A low-value pick is a low-value round, and no amount of play changes that.
  4. Re-triggers keep the same expanding symbol, so a premium pick plus a re-trigger is the combination worth hoping for.
  5. The gamble feature is a coin flip on a game that already has high volatility. Using it on a big free-spins win is how most of them disappear.

Who this slot is for

Book of Dead is for players who prefer tension over variety. If the idea of a single round, drawn at random, deciding everything sounds exciting rather than thin, then this is the game that invented the feeling and it still does it well.

It is not for players who want something happening on every spin. There are no modifiers, no multiplier trails and no second feature: ten years of Play’n GO releases have added all of that to other games and none of it here. Nor is it for anyone who cannot check which RTP build they are on, because the gap between the top and bottom version is wider than the difference between most good and bad slots.

For everyone else, the Book of Dead demo above answers the question in about fifteen minutes, free.

Book of Dead demo and slot FAQ

Can I play the Book of Dead demo for free?
Yes. The Book of Dead demo at the top of this page runs the full game with play money — no signup, no deposit and no download. It is the same reels and the same free-spins round you get with real money, so it is the fairest way to try the game before you stake anything.
What is the RTP of Book of Dead?
96.21% on the highest certified build. Play’n GO itself publishes no RTP, and SlotCatalog records five certified levels for this game: 96.21%, 94.25%, 91.25%, 87.25% and 84.18%. The casino chooses which one it runs, and its attributes panel lists 94.25% as the one it sees. Check the in-game information screen at your casino before playing for money.
What is the max win in Book of Dead?
SlotCatalog records a ceiling of 5,000× your total bet. Play’n GO publishes no maximum-win figure on its own game page, so that is a database figure rather than a studio one. Reaching it needs a high-value expanding symbol and re-triggered free spins.
How do the Book of Dead free spins work?
Three or more Book scatters anywhere on the reels award ten free spins. Before the round starts, one ordinary symbol is chosen at random to be the Special Expanding Symbol for the whole round: when it lands it expands over all three positions of its reel, and expanded symbols do not need to be adjacent to pay. Three or more scatters during the round re-trigger another ten spins.
Is Book of Dead high volatility?
Yes. Both databases we checked record it as high, and the design confirms it — ten paylines and one bonus round mean the free spins carry almost all of the return, with long flat stretches in between.
Can I play Book of Dead on mobile?
Yes. It is an HTML5 game of about 7.8 MB built for touch screens, and the Book of Dead demo on this page opens directly in a phone browser.
When was Book of Dead released?
14 January 2016, per Play’n GO’s own game page. It is the second game in the Rich Wilde series and the release that made the book format a standard across the industry.

Our verdict on Book of Dead

8.0/ 10

A landmark slot with one honest warning attached

Ten years on, the round still works. One random symbol, ten free spins and a payout structure that can run to 5,000× — it earned its place, and the Book of Dead demo above shows you why in a quarter of an hour. The feature set is thin by 2026 standards and the base game is flat, but the tension is real and the top build’s 96.21% is a fair deal.

What keeps it at 8.0 rather than higher is not the game but the product: five certified RTP builds ranging down to 84.18%, with no way to tell from the reels which one you are on. So play it free here, and if you move to real money, read the information screen first.
