To help her conquer the Lord, Lady, and Conqueror of Hell, Anna leans on the Book of Inferno, which is wild and also upgrades special symbols. There’s no time to waste, Anna is already on her way, and we need to come with her.

Book of Inferno Slot Information

Quickspin recently released Scatter Monsters, a casino slot in Hell with zombies, vampires, and demons. Book of Inferno follows the theme when Anna the Explorer ends up fighting the Lord of Hell, the Lady of Hell, and the Conqueror of Hell. According to Quickspin, we’re supposed to be somewhere between Hell and earth, but we’re probably way closer to Hell by the look of the surroundings. Burning lava floats on the ground, and a tornado-shaped light is burning in the dark sky.

The reels are made of stone with decorations of demons and other scary creatures. On top of them are small icons of the regular symbols. They can be lit up at any time in the Marked Symbol feature. To make a win, you need to land at least 3 of the same symbols on a payline, starting with the first reel to the left. Book of Inferno is available on mobile phones and other devices.

The lower-paying symbols in this hell-like environment are 9, 10, J, Q, K, and A. They pay between 8X and 12X the bet for a win containing 5 symbols. The higher-paying symbols are Commander of Hell, Lady of Hell, Lord of Hell, and Anna the Demon Huntress. The three bad guys have shining red or yellow eyes and vampire-like teeth. Landing a 5-of-a-kind win with Anna or the bad guys awards between 75X and 500X the bet. The Wild Symbol is the Book of Inferno, which also works as a Scatter Symbol, triggering the free spins.

Book of Inferno Slot Features

What is the max win in the slot Book of Inferno?

You can win up to 5846X the bet.

What features are available in the slot Book of Inferno?

The features are Wild Book of Inferno, Marked Symbol, Free Spins, and Bonus Buy.

Three reels completely covered with Q symbols in the Marked Symbol feature in the free spins.

Wild Book of Inferno

The Book of Inferno is magical in many ways. It substitutes all other symbols and also pays on its own, the same amounts as the best-paying symbol, Anna the Demon Huntress. Landing 3, 4, or 5 books anywhere on the reels triggers 10, 15, or 25 free spins and pays 2X, 20X, or 200X the bet. Any book landing during the Marked Symbol feature will also upgrade the Marked Symbol.

Marked Symbol

Any of the symbols can land as a Marked Symbol on any spin. When the symbols of the specific type land, they expand to cover their entire reel and pay on any winline without having to be in sequence from left to right. In other words, the Marked Symbols make wins even if the winning symbols aren’t on adjacent reels.

Any Book of Inferno landing will upgrade the Marked Symbol one step, potentially creating more winning lines. If the Marked Symbol is the highest-paying symbol, the Book of Inferno will upgrade the lowest-paying symbol into the highest. All free spins are played with a Marked Symbol that is randomly chosen before the feature starts.

Free Spins

You end up in the Free Spins by landing at least 3 Books of Inferno, and you can retrigger the same amount of spins by landing at least 3 more books. The Marked Symbol feature is active on all free spins, and a random symbol will be selected before the free spins start. The free spins continue until you run out of spins.

Bonus Buy

The free spins are for sale. You can pay 125X the bet for a spin that guarantees to land at least 3 Books of Inferno.

Book of Inferno Slot Conclusion

We love to see Anna the Explorer back on an adventure, this time as a Demon Huntress. Book of Inferno takes the player to a dark place where evil seems to rule. An inferno is a very large uncontrolled fire, and we’re in the middle of what seems like Hell. Book of Inferno shares the same setup of 5 reels, 3 rows, and 10 paylines as Book of Duat. Another similarity is that both games have an incredibly valuable book that functions as Wild and Scatter Symbols. Not only can you make valuable wins with the Book of Inferno, but it can also trigger up to 25 free spins in the inferno.

The Marked Symbol is a great feature that can be triggered on any spin, and it’s active on every free spin. It’s similar to the Expanding Symbol in Book of Duat, where it only appears in free spins. Marked Symbols can make wins even if the symbols aren’t of adjacent reels, which helps a lot in creating winning combinations.

The graphics of Book of Inferno are great, and we appreciate the animation when the Marked Symbol feature triggers. The max bet of 5846X the bet is alright for a highly volatile slot but far from impressive. It’s also much less than Book of Duat’s impressive max win of 32760X the bet. The RTP of 96.15% is pretty standard; just make sure you’re not playing any version with lower RTP. 

Book of Inferno from Quickspin follows Anna the Demon Huntress, when she’s fighting against evil forces that want to take over the earth.
