Leave it to Quickspin to turn up the heat with a tried and tested slot formula. The developer’s Book of Inferno slot game takes the “Book of…” template and tosses it into the fiery pits of hell, quite literally. This game takes players deep into the underworld and dazzles them with expanding symbols and bonus spins, as well as some good winning potential. Does Book of Inferno do enough to make it stand out from other “Book of…” titles though? Let’s take it for a spin and find out in this Book of Inferno slot review.
The Book of Inferno slot game has a fantastic design. The reels are floating around in the pits of hell, with the devil and various other demons making appearances on the reels. The whole thing is doused in flames, helping to immerse players in the environment and turn up the heat quite a bit. The initial design would have been enough, but Book of Inferno keeps things exciting with some excellent animations that help you jump between different loading screens and bonus features. Quickspin deserves a lot of credit for its design work here.
While the Book of Inferno slot certainly looks as though it turns up the heat, players don’t need to worry about getting burned by the gameplay. The slot uses a standard 5x3 grid with 10 active paylines on each spin. This setup is used in almost all top online slots that use the “Book of…” name.
The stake for the game is adjusted using the +/- buttons located under the grid. The minimum bet in the game is $0.10 and the maximum is $100, giving this a healthy betting range.
Who knew that the fiery pits of hell would look so good on a mobile device? Quickspin, apparently. The company has developed the slot with mobile users in mind, and it works really well on the smaller screen. The game has been fully optimized to support mobile play on both Android and iOS operating systems, ensuring you can take it for a spin at new casinos while you’re out and about.
The “Book of…” games are defined by their Bonus Spins and Expanding Symbols bonuses, and Book of Inferno is no different, though, it does manage to put a devilish twist on one of these elements.
This twist comes with the Marked Symbols bonus. If a Marked Symbol lands, it will expand to cover the entire reel. If a Book Symbol lands on the same reel, then the symbol is upgraded by one value.
The Free Spins Round is launched when players land three four or five of the Scatter symbols. This triggers 10, 15, or 20 spins respectively. When the Free Spins kicks off, an animation plays out with the titular book deciding which symbols will become marked and expand every time it lands in the round.
Depending on your location, the option to do a deal with the devil and buy your way into the bonus rounds may be available. This will not be available in the top online casinos.
Book of Inferno turns up the heat further with its highly volatile gameplay, being given the highest possible rating from Quickspin. The RTP for the slot sits at 96.15%, putting it slightly higher than average. Players should be aware that there are different versions of the game available. Check the paytable before you spin to make sure you have the best RTP available to you. The maximum win on offer in the game is 5,846x the player’s stake, which is similar to what you will find in other “Book of…” games.
With so many “Book of…” titles on the market, it can be tricky to know which ones are worth taking for a spin and which ones are best avoided. Take it from us: Book of Inferno is one of the hottest you can find right now. The game looks brilliant, with Quickspin really separating it from the rest of the crowd with some excellent design work and animations. The gameplay features are largely the same as other “Book of…” titles, but the Marked Symbols features add a stylish twist. We are happy to highly recommend taking this slot for a spin at the best online real money casino.
