Book of Inferno

Book of Inferno

• Quickspin takes players into the depths of the underworld in Book of Inferno, a fiery take on the classic "Book-style" slot format. While the genre is crowded, this one stands out with top-tier visuals, a highly detailed and immersive theme, and a few modern twists on the expanding symbol mechanic. Whether you’re a seasoned explorer of ancient tomes or just dipping your toes into hellfire, this one’s worth a spin.

How to Play

• Book of Inferno follows the traditional 5-reel, 3-row layout with 10 paylines, blending familiar mechanics with modern enhancements. Your primary focus will be on:

• Premium symbols, which pay between 75x to 500x your stake for five of a kind

• The Book symbol, which acts as both the wild and scatter, helping complete wins and triggering the bonus round

• Marked symbols, which randomly appear during gameplay to become special expanding symbols — these are key to unlocking full-line wins even if symbols aren't adjacent

• When the Book lands simultaneously with a marked symbol, the next tier symbol above it can also become marked, opening up more expanding symbol opportunities across the reels.

Theme & Graphics

• Set in a hellish underworld filled with fire, demons, and dark magic, Book of Inferno is visually rich and finely polished. The design is sleek, cinematic, and more refined than your average book slot — especially the Book symbol itself, which glows ominously and is the visual centerpiece of the game. The atmosphere leans into infernal mythology, with haunting sound design and animations that elevate the experience.

Bonus Features

Expanding Symbols

• At any point during the base or bonus game, symbols may become "marked" — appearing with glowing outlines above the reels. When enough marked symbols land in view, they expand vertically to cover their reels, paying out even if not adjacent. Landing the Book symbol together with a marked symbol increases the potential, adding a higher-tier symbol to the list of marked ones for that spin or round.

Free Spins

• Trigger the Book of Inferno Bonus Round by landing:

• 3 Book symbols – 10 free spins + 2x your stake

• 4 Book symbols – 15 free spins + 20x your stake

• 5 Book symbols – 20 free spins + 200x your stake

• Before the round begins, a random symbol is chosen as your main expanding symbol — similar to the mechanics seen in other "Book of..." slots. The marked symbol mechanic remains active during free spins, offering extra layers of win potential. You can also retrigger the bonus by landing 3, 4, or 5 books during the round, awarding the same number of spins and payouts again.

Bonus Buy Options

• If you're playing from a region where Bonus Buys are allowed (excluding UK), you can buy your way into the bonus round for 125x your stake. This guarantees at least 3 Book symbols on the next spin, and you’ll immediately enter the free spins feature. When purchased, the game runs at a top-tier RTP of 96.65%.
