Book of Dead is an Egyptian-themed slot from Play'n GO, and one of the most widely distributed slots across UK and European online casinos — it functions as a spiritual successor to the "Book of Ra" style of game, built around a randomly selected expanding symbol during free spins.
How it plays
A standard 5-reel, 3-row grid with 10 fixed paylines. The defining mechanic is the free spins round: landing 3 or more scatter (book) symbols triggers 10 free spins, and one regular symbol is randomly chosen at the start of the round to become an expanding symbol for its entire duration — every reel it lands on expands to fill the whole reel, which is where the game's largest wins come from.
RTP and volatility
Play'n GO publishes a default RTP of 96.21% for Book of Dead. Volatility is high — the base game pays modestly, and most of the game's value is concentrated in triggering the free spins round and getting a favorable expanding symbol.
Why it's still this widely offered
Book of Dead has remained a staple game library title at many operators for years after release, largely because of its straightforward mechanic and broad player familiarity — it's frequently used as a wagering-eligible or demo-available title precisely because of how established it is.
Who it suits
Players who want a simple, well-understood high-volatility mechanic (one big feature, not several layered systems) and don't mind a base game that plays relatively flat between free spins triggers.
