Book of Inferno review

Theme and Style

Players will descend into a fiery underworld with Book of Inferno.

Anna the Demon Huntress leads players on a perilous mission to find a legendary book. If they can defeat a variety of demons, they might escape this world of brimstone alive.

Players who enjoy fantasy and superhero narratives may especially enjoy this slot.

Graphics, Sounds and Animations

Book of Inferno’s soundtrack is infused with a heavy metal tone and a fast-paced drumbeat. This creates plenty of dramatic tension, though some players might find the relentless rhythm unsustainable for longer sessions. For them, the mute button is at hand.

The high quality graphics immediately give Book of Inferno an immersive feel. A hellish landscape in the background features glowing lakes of lava and plenty of sharp rocks.

The reels are accented with winged gargoyles that add to the gothic aesthetic. Among the symbols, players will find letters etched into glowing metal, along with a number of intimidating demon characters. One of the most intimidating is a four-eyed demon with her tongue extended like a snake.

This slot’s heroine is Anna, one of Quickspins' recurring characters, and in this incarnation she is a demon huntress. She sports a superhero-style ensemble, and her glowing green eyes make it clear she has special powers.

Overall, the soundtrack and animation of Book of Inferno create an exhilarating adventure fantasy.

The Book symbols are Wild symbols that substitute for all symbols.

A Marked symbol will expand to cover its entire reel whenever there are enough Marked symbols to create a win. These symbols do not need to appear in sequence on the reels for win evaluations.

When players land 3 or more Book symbols, the Free Spin feature begins. The number of free spins as well as the special multiplier awarded depend on the number of triggering Book symbols.

The Free Spins feature can be retriggered within the feature.

Throughout the Free Spins feature, a randomly selected symbol is selected to be a Marked symbol.
