Book of Dead
Book of Dead is Play'n GO's Rich Wilde Egyptian slot and one of the most-copied templates in the industry. The standard version returns 96.21%, runs high volatility, and tops out at 5,000x your stake on a 5x3 grid with 10 paylines. The Book of Dead symbol acts as both scatter and wild; three or more trigger 10 free spins with one randomly chosen expanding special symbol. The critical caveat: Play'n GO ships multiple lower-RTP builds of this title, with versions as low as around 94% and 92% in circulation, making the RTP check more important here than on almost any other popular slot.
Key takeaways
- RTP: 96.21% standard, but Play'n GO distributes builds as low as ~94% and ~92%. The version at your casino is the one that matters; check the info panel.
- Volatility: high. Most wins come from the free-spins expanding symbol, so dry base-game runs are expected.
- Max win: 5,000x your stake, achievable when the expanding special symbol fills multiple paylines during free spins.
- The Book: single symbol that triggers free spins (scatter) AND substitutes for all others mid-game (wild).
- Free spins: 3 Books = 10 free spins; one special symbol is chosen randomly and expands to fill its entire reel when it appears during the round.

The mechanic that launched a genre
Book of Dead is a 5x3 slot with 10 paylines and a design that has been replicated more than almost any other in the market. The central idea is one dual-purpose symbol: the Book of Dead functions as a wild that substitutes for all others during normal play, and as a scatter that triggers free spins when three or more land anywhere on the grid. During free spins, one randomly selected symbol becomes a special expanding symbol that fills any reel it lands on. That is the entire feature set, and it is enough.
Play’n GO released it as part of the Rich Wilde character series. The game’s longevity is a function of how well the mechanic scales with volatility: a single strong expanding-symbol run in free spins can change a session completely, but those runs are genuinely rare.
The RTP warning that matters most for this game
Book of Dead has a more serious RTP version problem than most popular slots. Play’n GO has made multiple builds available to operators across different regulated markets, and the versions in circulation include configurations around 94% and approximately 92% as well as the standard 96.21%. The game is visually identical at every RTP level, the symbols look the same, the feature triggers the same way, and there is no banner or badge indicating which version is running.
The 4-percentage-point gap between the standard version and a 92% build is not a rounding difference. Over a long session, playing a 92% build instead of the 96.21% version means the math is working against you noticeably harder. The check takes ten seconds: open the game at your casino, navigate to the information or paytable panel, and read the RTP figure printed there. If the casino does not display the RTP in the game interface, that is worth noting before you commit a session budget.
Free spins: how the expanding symbol decides everything
Three Book scatters anywhere on the grid award 10 free spins. Before the round begins, the game selects one symbol from the paytable at random to be the special expanding symbol for that session. You can see which symbol has been chosen at the start of the round.
When the special symbol appears on any reel during free spins, it expands immediately to fill all three rows of that reel, and it is then evaluated across all 10 paylines crossing through it. A symbol covering a full reel on a payline game counts toward every combination that passes through that reel.
The payout range within the free spins depends heavily on which symbol is selected. Rich Wilde appearing on three or four reels at once is the highest-value outcome. Lower-value symbols like the card ranks can expand across multiple reels in the same way, but the per-combination pay is smaller. Three more scatters during the round retrigger 10 additional spins.
Base game and high volatility in practice
Outside of free spins, Book of Dead pays through standard matching runs on the 10 paylines. The Book itself acts as a wild and substitutes for all other symbols, which adds occasional base-game wins. Returns between bonus triggers are modest: the design channels value into the free-spins round, and long stretches without a meaningful payout are expected.
High volatility here means that a session of 80 to 100 spins can pass without the feature triggering. That is not unusual for the game’s structure, and adjusting stakes to recover a losing run introduces more risk rather than correcting the situation, since each spin is fully independent of the ones before it.
Choosing where to play
Because the RTP version is such a variable for this title, the casino selection matters more than usual. The operators on our crypto casinos and fast-payout casinos lists tend to operate transparently and display game RTP within the interface. Confirming the version before starting is the most useful piece of due diligence you can do for this specific game.

Frequently asked questions
What is the RTP of Book of Dead?
The standard RTP of Book of Dead is 96.21%. That is the headline figure, but it is not necessarily what you play to. Play'n GO supplies lower-RTP builds to operators, and versions at around 95%, 94%, and as low as approximately 92% exist across different casinos. The game looks and plays identically at every RTP level. Always open the information panel at your specific casino and read the figure shown before placing a bet.
How does the Book of Dead free spins round work?
Landing three or more Book of Dead scatter symbols anywhere on the reels triggers 10 free spins. Before the round starts, one symbol is selected at random as the special expanding symbol for that session. During the spins, if that symbol appears on any reel it expands to fill the entire reel and is evaluated across all 10 paylines. Rich Wilde as the special symbol is the highest-paying outcome. Three more scatters during the round retrigger 10 additional spins.
What is the expanding special symbol in Book of Dead?
At the start of each free-spins round, the game randomly selects one symbol from the paytable to act as the special expanding symbol. If that symbol lands on any reel during the bonus, it stretches to fill all three rows of that reel and counts toward every payline running through it. Which symbol is selected matters significantly: Rich Wilde expanding across three or four reels pays far more than lower-value card symbols doing the same.
Is the 96.21% RTP reliable across all casinos?
No. Play'n GO provides operators with multiple RTP configurations, and casinos choose which to deploy. Versions in circulation range from 96.21% down to approximately 94% and as low as around 92%. A 4-percentage-point difference is substantial: over 1,000 spins it means roughly 40 units more returned on the higher-RTP version. The only reliable check is the game's own info panel at your specific casino, which shows the active configuration.
What is the maximum win on Book of Dead?
The maximum win on Book of Dead is 5,000x your stake. It requires the expanding special symbol to be Rich Wilde, for him to appear on multiple reels during the same free spin, and for the remaining positions to complete several paylines simultaneously. It is a realistic outcome in a strong free-spins round, not a purely theoretical figure, but it still requires everything to align and should not be treated as a likely session result.
Why is Book of Dead so popular?
Book of Dead established a mechanic template that dozens of games have copied: the book symbol acting as both wild and scatter, plus an expanding special symbol in free spins. It was among the first high-volatility slots to execute this cleanly with a 5,000x ceiling that felt genuinely reachable. That combination of simple structure and a high-stakes bonus made it a reference point, and its continued popularity reflects that the mechanic still delivers.
