Book of Inferno RTP and Volatility

This game has a high volatility rate and an RTP of 96.15%.
Book of Inferno is a high-variance game which means that it won’t be that easy to hit a win. However, the cash prizes should be on the higher side so it’s worth the risk. The RTP of 96.15% is a pretty good percentage for an online slot. This parameter indicates how the game will pay out to players for every €100 spent on bets.



Book of Inferno

Partially inspired by Dante’s opus The Divine Comedy, this game takes place at the gates of hell with creepy sculptures, lakes of fire, and dark ominous skies seen in the background. This place is populated by demons and evil spirits and looks terribly scary and haunting. However, Quickspin has added Anna the Demon Huntress to the storyline, and this character is the only one able to defeat demons and save our planet. The quality of visuals and audio in this game is amazing. The color scheme is dark and heavy while the background sounds and noises add an extra layer of horror.

The 5x3 playing grid is set in the middle of the screen. It is filled with highly-detailed animated symbols. There are 9-A playing card icons representing the low-paying symbols. The medium symbols have much more advanced designs and include the Commander of Hell, Lady of Hell, Lord of Hell, and Anna the Demon Huntress. These symbols pay for combinations of 2 to 5 matching symbols, with the highest payout of 500x granted by Anna.

The Book with the demon’s eye is both the Wild and the Scatter in this game. It can substitute for any other icon and trigger the Free Spins round.

Marked Symbol

Every standard icon can land as a Marked symbol. If you create a winning combo with Marked symbols, they will expand and cover the entire reels. If a Book lands on the payline along with a Marked symbol, it will upgrade the Marked icon to the next higher-value symbol.

Bonus Buy Feature

In Book of Inferno, you can purchase the free spins round and skip waiting. But don’t forget that it will cost you 125x your current bet to trigger this bonus round. The RTP of the Bonus Buy is 96.65%.

Book of Inferno Demo Play

Max Win

The maximum amount you can win in this game is 5,846x.
Book of Inferno is very impressive in terms of visuals, but, unfortunately, this is not the case with its winning potential. In this game, the maximum possible win is 5,846x your bet which is kind of low for a high-volatility game. Look out for Book symbols and the Demon Huntress as these are the game's most valuable icons paying 500x for the biggest winning combos. Also, the Upgrade Expanding Symbols feature can turn any spin into an Epic Win, paying all ways from all positions!

Book of Inferno slot - EPIC WIN!

Overall Rating
Book of Inferno is an exciting slot from Quickspin that offers a captivating gaming experience from the get-go. A lot has to do with stunning graphics and an original haunting soundtrack creating an immersive effect. There are plenty of bonuses to keep players engaged, including the Buy Feature that allows purchasing the bonus round which is not so easy to trigger in a high-volatility game. If infernal landscapes and demonic as well as a high volatility rate don’t scare you off, this slot could become your go-to game.
