Free slot: Book of Inferno

How to play Book of Inferno 

Quickspin is a provider that has seen its number of players grow significantly. This company always offers unique concepts, and this is still the case with Book of Inferno.  

This game released on February 7, 2023 is very volatile and offers several different and new features.  

The starting grid is classic, consisting of 5 columns with 3 symbols inside. The stakes vary from 0.10 euro to 100 euro per game round. 

Grab your book and dive into the heart of hell to find the jackpot there.  

During your paying spins, a feature may appear. On a game spin, a symbol will be chosen. In our example, we will take the J symbol. 

On the top of your starting grid are displayed all the symbols that are present in the game. 

Unlike the classic Book of Slots where the symbol is the main one, this is not the case here. Your J symbol can be upgraded to a Q symbol. 

But, and this is what makes Book of Inferno so explosive, it's the J and Q symbols that will turn into gold boxes. 

These gold squares will expand over the entire column where they are located and then connect with all other similar symbols.  

10 different paylines are available in this Quickspin slot. The connections work only from left to right and only the highest paying payout is taken into account. 

During the free games, all 10 paylines work in the same way. v 

Special features  

3 scatter symbols will get you the free games on Book of Inferno.  

Once this happens, you will be entitled to 10 free games. 

For every 4 symbols you get, you get 15 free spins and for every 5 scatters, you get 20 free spins. 

It will be possible to get more free spins by getting 3 bonus symbols again. 

If you don't have the patience to get the free spins in the classic way, you can buy them for 125 times your starting bet. 

During your free games, it works a little differently. A symbol will be chosen before the start. This symbol will be the main symbol and will work like a classic Book of slots. 

As soon as a symbol appears a minimum number of times, it will expand on your columns and connect. 

As soon as a book symbol appears, it works differently. Just like during your pay spins, your main symbol will be upgraded or moved to the next column.  

For example, the symbol on the far right, if a book appears, will stay and it will be the 9 that becomes a changing symbol. 

The way it works is the same: as soon as the book appears, the main symbol and the upgrade symbol will change into gold symbols and expand (if they appear the minimum number of times), and then make a connection.

Reviews of Book of Inferno 

We really enjoyed playing the Book of Inferno machine. Quickspin has done an excellent job with their very well designed game.  

This is not a classic Book of machine as it offers a unique concept. It allows you to increase the volatility of the game considerably. Thrill seekers will get their fix on this highly volatile slot. 

It's explosive, just like the main payout. With a jackpot of 5,846 times your starting bet, you'll have plenty to enjoy if you win. 

The RTP of 96% is about average, which is another strong point. This game is perfect for beginners, as it is very easy to pick up. For experts, you'll quickly realize how much this game can pay you on any given spin.  

The bonus buying feature is another positive point. If there is a negative point to be given to this game, it is the very large number of baits before you get free games. This is unfortunately the problem of this provider which can be very frustrating in this respect.
