The definitive book slot and still the reference point for the entire genre. If someone says book slot, this is what they mean.
One draw decides the feature
At the start of free spins, one symbol is chosen at random to become the expanding symbol. When it lands during the feature it expands across the reels, which is where the big line wins come from. Drawing a high-value symbol produces the sessions people post about; drawing a low card produces the ones they do not. You have no influence over the draw.
Classic paylines, not a cluster grid
Book of Dead is five reels and ten paylines: the structure slots used before pay-anywhere grids took over. Players who prefer a classic payline structure to modern cluster grids. It is also a straightforward way to see volatility at work, because nearly all of the game’s value is concentrated in that one feature.

Bankroll for a draw-driven game
Because a feature can land on a low symbol and pay little, you need enough balance for several features, not one. On high-volatility games, budget for hundreds of spins; the real money slots guide does the arithmetic in rupees.

At random, at the start of free spins. It then expands to cover its reel whenever it lands during the feature. The player has no influence over the choice.
Is Book of Dead high volatility?
Yes. Nearly all of its value sits in the free spin feature, and the symbol draw makes results swing widely.
