Metallic card suits form the lows; demonic characters headline the highs—Commander of Hell, Lady of Hell, Lord of Hell—with Anna the Demon Huntress as the top premium. The Book can pay on its own: 2/3/4/5 award 1x/10x/100x/500x your stake, respectively.

Book of Inferno Features & Bonuses

Marked Symbols & Expansions

At any time, a fiery pentagram animation “marks” a random symbol. That symbol is highlighted above the reels and will expand to fill its reel during the next spin—if enough land to form a win. Expanded wins pay without needing adjacency. If the Book lands on the same spin, it can upgrade the marked symbol to the next higher tier for bigger payouts.
