Play Book of Inferno

Book of Inferno is an online slot with a 5x3 reel setup and 10 fixed paylines. You can bet between 0.1 and 100 on this game and win up to 5,846x your stake. The bonus features include Wild symbols, Expanding symbols, Free Spins, and a Buy Feature. The latter allows you to activate Free Spins for 125x the bet. This game has a high volatility rate and an RTP of 96.15%.

The lower-paying symbols in this hell-like environment are 9, 10, J, Q, K, and A. They pay between 8X and 12X the bet for a win containing 5 symbols. The higher-paying symbols are Commander of Hell, Lady of Hell, Lord of Hell, and Anna the Demon Huntress. The three bad guys have shining red or yellow eyes and vampire-like teeth. Landing a 5-of-a-kind win with Anna or the bad guys awards between 75X and 500X the bet. The Wild Symbol is the Book of Inferno, which also works as a Scatter Symbol, triggering the free spins.

Any symbol can be a Marked symbol, and they land randomly on the reels. If there are enough of them at the same time to pay, the Marked symbol will spread across the entire reel and pay anywhere on the grid, regardless of the formation. Suppose a Book lands on the reels together with the Marked symbol. Then the Marked symbol gets upgraded one step to the next value symbol and potentially creates more expanding Marked symbols.

Books are also key for the Free Spins feature. If three, four or five Books land on the reels, you get 10, 15 or 25 Free Spins, respectively.
