Book of Inferno Features

Book of Inferno blazes with an array of captivating features, including Expanding Symbols, Free Spins, Scatter symbols, and the innovative Buy Feature, creating a dynamic gameplay experience that's loaded with excitement and winning potential.

Buy Feature

The Buy Feature in the Book of Inferno slot by Quickspin is a unique gameplay mechanic that offers players the opportunity to directly access the Free Spins feature without waiting for it to be triggered naturally through gameplay. Instead of relying solely on Scatter symbols landing on the reels to activate Free Spins, players can opt to use the Buy Feature. By paying a specific amount, usually higher than the standard bet, players can instantly unlock a set number of Free Spins rounds. This provides a shortcut to the bonus round, where the potential for bigger wins and exciting gameplay features is often higher.

Expanding Symbols

When this feature is activated, a specific symbol is chosen at random before the Free Spins round begins. During the Free Spins, whenever this chosen symbol appears on the reels, it has the unique ability to expand and cover the entire reel it's on. At the start of the Free Spins feature, one regular symbol is randomly selected to become the Expanding Symbol for the duration of the round. Whenever the chosen symbol lands on the reels, it will expand vertically to cover the entire reel if it can create a winning combination. This expansion occurs after regular wins are paid out. The expansion of symbols often leads to multiple winning combinations being formed in a single spin. This can significantly boost the potential payouts during the Free Spins feature.


The Free Spins feature in the Book of Inferno slot by Quickspin is a thrilling bonus round that offers players a set number of spins without requiring them to place additional bets. This feature is often triggered by landing a specific number of Scatter symbols on the reels during the base game. Once triggered, the game grants you a predetermined number of free spins. This number can vary from slot to slot. In the Book of Inferno slot, you'll receive a certain number of spins to play without deducting any funds from your balance. During the Free Spins feature, the Expanding Symbols mechanic might also come into play. As explained earlier, a symbol is randomly chosen to expand and cover entire reels, increasing the potential for big wins.

Scatter symbols

Scatter symbols play a special role in slot games like Book of Inferno by Quickspin. They are unique symbols that don't need to appear on specific paylines to trigger their effects. Instead, they can appear scattered anywhere on the reels to activate various bonus features or rewards. The number of Scatter symbols required to trigger a feature can vary from slot to slot. In Book of Inferno, for instance, you might need to land three or more Scatter symbols to activate the Free Spins feature. Unlike regular symbols that need to line up on specific paylines, Scatter symbols don't follow this rule. They can be scattered across the reels and still count towards triggering a bonus. While Scatter symbols themselves might not always offer direct payouts, the features they trigger, like Free Spins, often come with enhanced winning opportunities. 


Wild symbols are versatile symbols that can substitute for other regular symbols on the reels, helping to create winning combinations. Think of Wild symbols as jokers in a deck of cards – they can stand in for any other symbol (except special symbols like Scatters) to complete a winning line. In many cases, Wilds don't just substitute; they also come with a multiplier that increases the payout of the winning combination they are part of. This can lead to bigger rewards when Wilds are involved. Sometimes, landing multiple Wild symbols on a payline can also create its own winning combination. These combos often offer substantial payouts.

Book of Inferno Unique Features

Book of Inferno, a creation by Quickspin, stands out with its captivating blend of innovative features that ignite the gameplay. At its core, the slot boasts the compelling Buy Feature, enabling players to bypass the anticipation and instantly access the rewarding Free Spins round. The Expanding Symbols feature takes the excitement a step further, selecting a symbol that can stretch to cover entire reels during Free Spins, potentially leading to substantial wins.

Scatter symbols introduce the possibility of triggering the sought-after Free Spins feature, where the Expanding Symbols truly shine. Meanwhile, the presence of Wild symbols further intensifies the gameplay, aiding in forming winning combinations by substituting for other symbols.

Book of Inferno Winning symbols

The iconic Book of Inferno symbol serves a dual role as both a Scatter symbol, activating the enticing Free Spins feature, and a Wild symbol that substitutes for other symbols. Its payout scale, spanning from x1 to an impressive x500 of the bet, accentuates its significance within the game.

Anna the Demon Huntress, a central figure in the storyline, offers payouts ranging from x1 to x500, embodying the game's theme with both strength and allure. 

The imposing Lord of Hell commands payouts from x1 to x160, while the formidable Commander of Hell and the captivating Lady of Hell bring forth potential rewards ranging from x0.5 to x75.
