Book of Dead Slot Review — RTP, Volatility & Where to Play

Book of Dead is Play'n GO's most successful export and one of the defining high-volatility slots of the mid-2010s. Released in 2016, it built its reputation on a single mechanic executed cleanly: an expanding symbol during free spins that can cover an entire grid. A decade on, the fundamentals still hold up even if the format has been iterated upon extensively.

The game runs on a 5x3 grid with 10 paylines and an Egyptian tomb-raider theme centred on the explorer Rich Wilde. The Book symbol acts as both scatter and wild — land 3 or more to trigger 10 free spins. Before the free spins begin, one symbol is randomly selected as the special expanding symbol. During free spins, if that symbol lands anywhere on the reels it expands to fill its entire reel. Multiple reels covered by the expanding symbol on a single spin — especially the top-paying Rich Wilde symbol — are what drive the 5,000x maximum.

The base game is honest about what it is: filler. Wins come from standard payline combinations and occasional wild substitutions. There is no cascading mechanic, no bonus feature beyond scatter collection, and no random events. Sessions in the base game prior to free spins triggering can run long without anything noteworthy. This is not a criticism — it reflects a deliberate design choice to concentrate variance into the free spins round — but players expecting base game engagement will find Book of Dead thin.

Free spins quality is almost entirely dependent on which symbol expands. The Rich Wilde symbol expanding is the jackpot scenario; a low-value card symbol expanding is a near-worthless round. This binary outcome is the game's defining characteristic. Retriggering free spins (land 3+ scatters mid-round) extends the session and can transform an average run into an excellent one.

The bonus buy (100x stake) is available at most casinos and provides immediate free spins access with the random symbol selection. RTP remains 96.21% on the buy. At regulated markets that prohibit bonus buys, the game is still popular as a manual-trigger slot.

Book of Dead remains relevant because it is available everywhere, accepted in most bonus terms, and the expanding symbol mechanic — while simple — delivers genuine excitement when the right symbol is selected. It's not cutting-edge, but its mechanics are honest and the ceiling is real.
