Book of Inferno Game Overview

Book of Inferno is a Quickspin slot with 5 reels and 10 paylines, and a 5×3 grid layout. As soon as the slot loads, it’s clear that Book of Inferno has a hell-inspired theme: the grid is set inside the underworld, which is bursting with flames, and various creepy devil-like creatures fill the reels.

You can play Book Of Inferno at our fast withdrawal online casino, King Casino, for stakes ranging from £0.10 per spin up to £30 per spin; this is a decent betting range that may appeal to a range of players! 

Anna, the Demon Huntress, is the top-paying symbol, paying out up to 500x your bet for landing 5 on a payline. 

How To Play Book Of Inferno

In Book Of Inferno, the marked symbols become special expanding symbols. Aside from the special expanding symbols, Book Of Inferno works largely like any other typical online slot machine. Let’s go through the basics of gameplay:

Once you have launched the game, click on the menu icon. This is where you can find the rules and paytable. The paytable has information on winning paylines, payouts, and how to unlock bonus features.

Next, you can place your bet by choosing among the available options; you can find these by clicking the stacked coins icon. Then, if you’re ready, you can hit spin to begin your game.

Wild And Scatter Symbols

The book with the eye acts as both the wild and the scatter symbol in this slot. This symbol can replace all other symbols to possibly help complete wins, and it can help trigger the Extra Spins feature.

Extra Spins Feature

Land 3 or more book symbols to trigger the Extra Spins feature. Landing 3, 4 or 5 book symbols awards 10, 15 or 25 Extra Spins, as well as 2x, 20x or 200x your stake, respectively. 

Before each round, a random symbol will become marked. You can re-trigger the feature by landing 3 or more book symbols again.

Marked Symbols

Random symbols can be marked at any point during gameplay or during Extra Spins. The marked symbols then become special expanding symbols. 

If you land a winning combination with marked symbols, they will expand and fill the entire reel to boost winning potential. If a book symbol lands on a payline with a marked symbol, the symbol will upgrade in value to the next highest-paying symbol. 

This could potentially lead to more expanding symbol wins.

Return To Player

Return to Player (RTP): 96.15%

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
