Book of Inferno

Quickspin's video slot, Book of Inferno, showcases a traditional layout consisting of 5 reels, 3 rows, and 10 fixed paylines. The game immerses players in a fiery setting populated by demons, with Anna the Demon Huntress as the central character, contributing to a dark and captivating ambiance accentuated by impressive visual effects. A significant feature of this game is the "Book" symbol, which functions as both a wild and a scatter, enabling it to replace other symbols and activate Free Spins.

One of the game's standout mechanics is the Marked Symbol feature, where a random symbol is chosen. When sufficient instances of this symbol appear to create a win, they expand to fill the entire reel and pay out in all directions, eliminating the need for a left-to-right pattern. If a Book symbol lands alongside the Marked symbol, it enhances the Marked symbol, promoting it to a higher level, and if it exceeds the highest level, the lowest symbol is upgraded to the highest.

Landing 3, 4, or 5 Book scatters triggers Free Spins, granting 10, 15, or 25 free spins, respectively. Each trigger of Free Spins also includes a win multiplier of 2×, 20×, or 200× based on the number of scatters. During the Free Spins, a symbol is randomly selected as Marked, and the Marked Symbol feature remains active, allowing for further upgrades throughout the bonus round.

Moreover, players have the option to use the Bonus Buy feature, which allows them to pay 125× their stake to gain immediate access to Free Spins, ensuring at least 3 Book scatters on the next spin and instantly activating the bonus round. However, this feature may not be accessible in every region.

In summary, Book of Inferno combines classic "Book-slot" features with innovative mechanics like expanding and upgrading symbols, offering a more engaging experience than many other games in its genre.
