Book Of Evil Slot Features

Expanding Symbols
During any base game spin, a random paying symbol expands to fill entire reels if it lands in sufficient quantities (2+ for high-paying, 3+ for low-paying).
Free Spins Bonus
Land 3+ Book of Evil scatters to trigger 10 free spins, with one regular symbol chosen to expand throughout the bonus round for increased win potential.
Wild Substitution
Wild symbols substitute for all regular icons to complete winning combinations and can retrigger free spins when landing as scatters.
High-Volatility Multipliers
Priest and Book symbols pay up to 400x bet for five-of-a-kind, creating the potential for the 250,000x maximum win during volatile swings.

Our Book Of Evil Slot Review

Book Of Evil delivers massive win potential with a 250,000x max payout, but the 94% RTP and high volatility make it a risky proposition compared to competitors like Book of Dead (96.2% RTP). The expanding symbol mechanic during base game spins is engaging, though the standard 5x3/10-payline format feels dated—this is for thrill-seekers chasing big multipliers, not casual players seeking steady returns.
