Book of Inferno features the best of both worlds for players containing traditions found within 'Book Of' slots as well as new mechanics that modern players will appreciate.
Throughout this slot, there are expanding pay anywhere symbols. This symbol is highlighted by being marked at the start of free spins but it can also randomly become marked throughout the base game.
When a marked symbol lands, if there are enough to pay, then the marked symbols expand to cover their entire reel. Alternatively, any book that lands together with a marked symbol will upgrade it one step creating even more marked symbols.
Alongside the marked symbol, there are also free spins that can be triggered. 3, 4 or 5 book symbols award 10, 15 or 20 free spins respectively. A random symbol will be selected at the start as the marked symbol.
Finally, non-UK players will be happy to find out that the free spins round can be purchased. By paying 125x the stake, the free spins round can be instantly awarded. However, this is only for players outside of the UK.
In order to trigger the free spins round, you'll need to land 3 or more book symbols or purchase the bonus buy. UK players will have no choice but to trigger the feature with the bonus symbols leading up to 20 free spins.
During the base game or the free spins round, a symbol can randomly be selected to become marked. When this happens, the symbol in question contains a gold frame and also expands when it's involved in a win.
There's a reason that 'Book Of' slots are so popular and it all boils down to the enjoyment that the simple slots deliver. If you are looking for a 'Book Of' slot, then you'll know exactly what you are getting in for.
Despite this, some slot developers have been trying to shake up the format with subtle changes which is what Book of Time did. Following this trend of reinventing 'Book Of' slots, Quickspin's Book of Inferno finds the right balance between keeping the gameplay straightforward without delivering minimalistic gameplay.
The first thing that will catch your eye is the epic rock music played as the game loads up. It's not too heavy to put you off but it definitely sets the pace for the slot. Alongside this, you'll find cheering from different demons and other ambient noises that enhance the experience even more.
As for the visuals, the design resembles World of Warcraft with realistic designs of the humans paired with fantastical elements. There are four main characters throughout this slot including Anna (the huntress), Lord of Hell (basically Satan), Lady of Hell and Commander of Hell.
The monsters look like the type of things you'd expect to find in Hell whilst the huntress resembles Kate Beckinsale from the Underworld film series. The design of the characters works well with the background filled with different lava pits and an overall scary environment.
It wouldn't be a 'Book Of' slot without a free spin bonus round. This one is triggered by landing 3 or more book symbols leading to up to 25 free spins. Once the free spins are triggered, an ordinary symbol is transformed into a marked one.
The marked symbol is gold and expands when formed in a win potentially leading to even bigger wins. These marked symbols can even appear during the base game leading to even more chances to win.
Book of Inferno keeps it fairly modest in terms of the win potential starting with an RTP of 96.15% which is just over the average. Following this, you'll find a high volatility level and a maximum win of 5,846x the stake.
The maximum win of 5,846x the stake is not as huge as other modern slots but it's quite good for a 'Book Of' slot. To achieve the maximum win, you'll need to trigger the free spins round and basically land a full screen of the highest-paying expanded symbol.
The presentation of Book of Inferno makes the slot stand out as a 'Book Of' that's worth a spin. It's not very often that you find a horror-themed 'Book Of' slot with tasteful graphics but that's exactly what you'll find with Book of Inferno.
Alongside this, you'll find solid gameplay and a decent win potential throughout. If you are a 'Book Of' slot fan, then be sure to give Book of Inferno a spin.
