Book of Inferno Overview

I was wondering how long it would take for Quickspin to release their version of a “Book of” slot game. And well, here we are with Book of Inferno.

Quickspin took a very cool, demon theme. With the pots of hell and different types of demons you might come across when you would be in hell.

It all looks very cool and you really feel like being in one of the circles in hell.

The game uses 5 reels that are each 3 symbols high and comes with 10 lines.

Besides standard card symbols, 9, 10, J, Q, K and A. You will also find four different demons. Beside this there is a book that counts as both wild and scatter and appears on all reels.

Book of Inferno comes with a maximum payout of 5.846 times your bet.

Book of Inferno Features

Marked Symbols

Marked symbols can appear at random during a base spin. And are specifically picked during the free spins bonus. Whenever Marked symbols land, if there are enough of them to create a winning combination, they will expand to cover the entire reel. These expanded symbols pay anywhere, so they don’t have to be adjacent or start on the first reel from left to right.

If one or more book symbols land at the same time as Marked Symbols, the Marked symbols are upgraded to the next highest value symbol. Any of those symbols already on the reels will now also become marked. If the marked symbol is the highest paying symbol then the lowest paying symbol, the 9, is converted into the highest paying one.

Free Spins Feature

3, 4 or 5 scatter symbols (books) will award 10, 15 and 20 free spins respectively.

Before free spins start a random symbol is picked to act as the Marked Symbol during all free spins.

3 or more scatter symbols will add extra free spins.

Bonus Buy

If a casino offers the option, you are able to buy the free spins feature for 125 times bet.


Of course there are a lot of these “Book of” games already. And new ones keep popping up almost every month.

So to create one that is unique and different you have to add something new and special. And that’s exactly what Quickspin did. The upgrade of symbols is a great addition and makes the overly produced “Book of” game interesting again.

And don’t forget the theme. It looks amazing and somehow fits perfectly with this game.

Overall I think Quickspin created an amazing new addition to the library of “Book of” slots. And definitely worth a try.
