BOOK OF INFERNO
Book of Inferno online slot produced by Quickspin comes with a default 96.15% RTP and a 5-reel, 3-row playing area featuring 10 pay lines.
Anna stood in front of a stone archway covered in etchings of demons and pentagrams. The inside of the structure’s frame was smooth as marble, with only five perfectly round sockets lined up at an equal distance. She walked over slowly, her jade eyes burning with fury, but her step controlled and confident, and placed a crimson gem into each opening. Nothing. The silence was as dead as the moment she stepped into this cursed sanctuary. She took a few steps back and reached for a heavy tome, which she instinctively opened right in the middle. Glancing at the inanimate arch, she recited the words from the book.
Streams of fiery energy burst from the awakened gems, connecting them and forming a pulsing pentagram. Anna murmured one final word, and the inside turned into a rippling surface, like a curtain moved by wind. She tossed the volume on the ground, unsheathed a glowing dagger, and snapped her fingers several times, releasing sparks of energy. Today this demonic invasion stops once and for all. Defeating the Commander, the Lady, and the Lord will be the biggest challenge she has ever faced, but she is well-prepared and holds a few aces up her sleeve.

How To Win On Book of Inferno Slot - Features & Mechanics
The slot offers a traditional 5x3 setup with 10 lines stretching across. You form regular wins from at least 3 (or, in the case of high-payers, 2) matching symbols starting from the leftmost reel. As usual for this format, the Book symbol acts both as Scatter and Wild, helping in creating or developing existing wins. If you played one or two titles featuring this structure, the paytable won't be a surprise either. The lowest combinations award half of your active stake, and top hits reach 500 times the bet for a 5-of-a-kind sequence on the Anna symbol or the Book.
Marked Symbol
Quickspin decided to diversify the gameplay in the base stage by adding a random feature that activates one of the regular symbols. The marked image will expand to cover the entire reel and pay anywhere. Additionally, landing at least 1 Book on the same spin upgrades the selected symbol to the next one in the hierarchy. If the first choice lands on the top position of the paytable, the conversion will apply to the lowest-paying icon and turn it into the highest one. The transformation naturally improves the chances of activating more expanding instances and potentially leads to more valuable wins.
Book of Inferno Free Spins
To enter the last circle of hell and face the demons, you need to land 3, 4, or 5 Scatters that activate 10, 15, or 25 free spins, respectively. As usual, there's also an instant win of x2, x20, or x200 accompanying the bonus trigger. Before the first spin, one regular symbol becomes the expanding one and acts accordingly throughout the entire round. The upgrade functionality is also present, allowing to significantly boost the winning combinations. If you don't need to prepare before the final fight and prefer to jump into the action straight away, the bonus buy option activates the free spins instantly for 125 times bet buy-in.
Book of Inferno On Mobile
The mobile experience delivered by Quickspin is always on the highest level, and Book of Inferno is not an exception. The slot runs smoothly in the newest HTML5 technology, providing hassle-free gameplay on all mobile devices. In landscape mode, the view is replicated after the desktop variant, while in portrait orientation, everything looks clean and readable, with the main playing area occupying the central part of the screen.
Final Thoughts
We won't serve you with another monologue questioning the reasoning behind a decision to produce a "Book of" slot. It is what it is, and apparently everyone wants to give it a go. Sometimes more than once. Book of Inferno comes with a couple of exciting twists regarding the mechanical side, on top of the standard grid composition and expanding symbols functionality. Firstly, offering the feature also in the base game is a great move that reshapes the original experience and adds an extra level of anticipation beyond hoping for the third Scatter. On top of that, each occurrence carries a possibility to improve the initial win by having the chosen symbol upgraded. That's a lot more than most games of this format offer. Transferring the enhancing mechanism to the bonus round completes the cycle and gives us a coherent technical composition focusing on a handful of crucial aspects driving the gameplay.
Significant effort is instantly noticeable regarding the audiovisual package, which is always on the highest levels when it comes to Quickspin games. Everything from the progressive intensity of low-paying royals to characters supporting the storyline and advanced big win celebration feels cohesive and thought-through. The subtle idle animations on the high-paying images make the scene a little more lively, while the overall hellish vibe is thrillingly reflected in the demon figures and the ominous environment full of skulls and lava. We can instantly feel a connection and support for the protagonist, a supernatural heroine who devoted her life to hunting down demons and protecting humanity. An uncomplicated but intense story like that efficiently turns the attention away from the fact that it's another installment of the omnipresent slot format.
Quickspin pumps up the temperature of a classic "Book of" game style with several exciting enhancements supported by a heroic backstory set in the depths of hell.
