01Book of Inferno at a glance

Book of Inferno is Quickspins interpretation of the classic book formula, released den 25 januari 2023 and steeped in fire and brimstone. Here the book is both scatter and key to free spins, and the theme revolves around demons, devils and the underworld's glow.

The game has an RTP of 94,19 %, high volatility and a win cap of 5 798× the bet. The title is in our pool export under ID 28650.

02Theme and atmosphere

The palette is dark — black, brown and blood red — and the symbols are populated by demons and devilish figures against a backdrop of hellish glow.

It's a noticeably hotter take on the book genre than the usual Egyptian variants: instead of desert sun you get underground fire, and the atmosphere leans toward the doom‑laden rather than the adventurous.

03How the game works

The base game spins symbols that pay from the left according to the game's paytable, and the book serves as both wild and scatter in the classic Book tradition.

If enough book symbols land, the free spins round is triggered, where a randomly selected symbol expands and can cover entire reels. The exact payouts per symbol are confirmed in the game's paytable.

04Bonus, expanding symbol and bonus buy

Free spins are the heart of the game: the expanding symbol is what creates the really big rounds when it fills multiple positions at once.

For the impatient there's a Buy Feature button that buys you directly into the free spins. The number of spins, expansion conditions and exact values are shown in the game and confirmed in the paytable.

05RTP, volatility and max win

With an RTP of 94,19 % Book of Inferno sits below the usual 96 %-benchmark, so the long-term margin is steeper than average. It is published as an RTP range that can vary between casinos.

Volatility is high and the cap reaches 5 798× the stake — wins come more sparsely but the big payouts are concentrated in free spins. A game for those who can tolerate dry spells in pursuit of maximum wins. Set a budget first.

Game rules

The mechanics from the rulebook — point by point

Base game and book symbol

Book of Inferno is played like a classic book slot where matching symbols pay from the left according to the game's paytable. The book acts as both wild, replacing paying symbols, and scatter, triggering free spins.

The exact multipliers per symbol are confirmed in the game's paytable.

Free spins, expanding symbol and bonus buy

When enough book scatters land the free spins round starts. A random symbol is chosen and expands to cover entire reels it lands on.

A Buy Feature button gives direct access to free spins. The number of spins, expansion rules and exact values are confirmed in the game — no figures are made up here.
