Introduction to Book of Inferno

Book of Inferno Base PlayA unique aspect of Book of Inferno is the Marked symbol feature, which adds an extra layer of excitement to the gameplay. Any symbol can become a Marked symbol, and when enough of them land on the reels, they expand to cover entire reels, paying out even if they're not on a payline. If a Book symbol lands with a Marked symbol, the Marked symbol upgrades, potentially creating larger clusters of expanded symbols. The ability to upgrade symbols and turn low-value ones into high-value ones adds a strategic element to the game. For players looking to bypass the regular gameplay, there is also a Bonus Buy option that allows them to purchase direct access to the Free Spins feature for 125x the bet, increasing the RTP to 96.65%.

Book of Inferno Slot Gameplay and Mechanics

Book of Inferno offers a thrilling gameplay experience with its 5 reels and 10 fixed paylines. The game’s core mechanics revolve around the Wild Book symbol, which acts as both a Wild and Scatter. It substitutes for all symbols to help form winning combinations and can trigger the Free Spins feature when three or more Books land on the reels. During the Free Spins, a random symbol is chosen to become the Marked symbol, which can expand to cover entire reels, significantly increasing the potential for larger payouts. Additionally, the Books that land during the Free Spins can retrigger the feature, adding more spins and enhancing the chances of hitting big wins.

The innovative Marked symbol feature is another key aspect of the gameplay. Any symbol can become Marked, and when multiple Marked symbols appear, they expand to cover entire reels and pay anywhere on a payline. If a Book symbol lands with a Marked symbol, the Marked symbol upgrades, potentially transforming lower-value symbols into higher-paying ones. This upgrade mechanic adds an extra layer of excitement, as it increases the potential for massive payouts by turning the symbols into more valuable ones. With the option to buy direct entry to the Free Spins feature for 125x the bet, the slot’s high volatility and innovative mechanics keep players on the edge of their seats.

Book of Inferno Slot RTP

96-97 RTP Range

The Book of Inferno offers a competitive RTP (Return to Player) of 96.15% in the base game, which is in line with many modern video slots. However, the RTP increases to 96.65% when using the Bonus Buy option, allowing players to directly access the Free Spins feature for a cost of 125x their bet. This slight increase in RTP reflects the potential for higher returns during the Free Spins, where the gameplay becomes more dynamic with the Marked symbol feature and symbol upgrades. While the game is highly volatile, the RTP offers a reasonable expectation of long-term payout potential for players looking to trigger the most rewarding features.

Book of Inferno Slot Volatility

High volatility icon

Book of Inferno has a high volatility rating, meaning that while the game may not produce frequent wins, the potential for larger payouts is higher. This makes it ideal for players who are willing to take on more risk in exchange for the chance to hit big rewards, especially during the Free Spins feature and when the Marked symbol upgrades occur. With a high volatility slot, the big wins tend to be more spread out, and the game can deliver larger payouts when the right combination of features aligns. Players should be prepared for longer stretches without significant wins, but the possibility of hitting a substantial prize makes the game enticing for those seeking higher-risk, higher-reward gameplay.

Book of Inferno Slot Betting Range

The Book of Inferno offers a flexible betting range that caters to a wide variety of players. With a minimum bet of just €0.10 per spin, the game is accessible to casual players who prefer to wager small amounts while still having the opportunity to trigger the game’s exciting features. This makes it a great option for those who enjoy lower-risk gameplay or want to extend their playtime without committing large amounts of money.

On the other hand, high-rollers can bet up to €100 per spin, giving them the chance to chase bigger payouts and take full advantage of the game’s high volatility. The large betting range allows players to tailor their wagers to their preferences, whether they are playing for fun or aiming for larger rewards during the Free Spins feature or through symbol upgrades. This flexibility in betting ensures that both conservative and more adventurous players can enjoy Book of Inferno without feeling limited by the betting options.

Book of Inferno Slot Symbols Explained

In Book of Inferno, the symbols are key to unlocking the game’s features and rewards. The Wild Book symbol is the most important, as it serves a dual purpose – acting as both a Wild and Scatter. As a Wild, it substitutes for all other symbols to help form winning combinations, while as a Scatter, it triggers the Free Spins feature when three or more appear on the reels. The Free Spins feature is central to the game, and the Wild Book can also retrigger it, providing more opportunities for larger payouts.

The regular symbols in Book of Inferno are themed around infernal creatures, with high-paying symbols like the Demon Huntress and other mythical beings. These symbols can offer significant rewards when landing in combinations across the reels. Lower-paying symbols include the traditional playing card icons, such as 10, J, Q, K, and A. During the Free Spins feature, a random symbol is selected to become the Marked symbol, which can expand across the reels and increase the chances of landing more winning combinations. The Marked symbol feature adds another layer of excitement, as it can be upgraded to boost payouts even further.

Book of Inferno Symbols

The symbols in Book of Inferno not only amplify the game’s fiery, infernal theme but also play a crucial role in unlocking its rewarding features. Each symbol offers different payout values and contributes to activating exciting bonus mechanics, especially during the Free Spins feature, where the Marked symbol can expand and trigger potential upgrades, leading to significant rewards.
