Book of Inferno Slot by Quickspin 🎰 Free Demo and Review

Book of Inferno Review

We have seen our fair share of Book slots in our time, as new installments keep cropping up all over the place. Some get more attention than others, and deservedly so, and we have a feeling that Book of Inferno will impress most Book slot fans out there. You’re taken to the pits of hell on a visually pleasing journey, and the attention to detail is highly impressive. This is not least the case for the book symbol itself, which is the best we’ve seen so far.

Dante had Virgil as a guide in his poetic descent into the Underworld, and you get demons of different kinds instead. They appear on larger wins mostly, and a massive and elaborate pentagram manifests the diabolical Book also in the base game. This gives you marked symbols that can expand ‘book of’ style, and these come in addition to the upfront chosen symbol in the bonus round. The max win of 5,846x your stake is a tad higher than usual, and Book of Inferno is well worth a closer look.

Book of Inferno Slot Features

The premium symbols pay between 75 and 500 x your stake for 5 of a kind wins, and the Book Wild steps in for pay symbols to help complete wins. The Book pays the same as the top-tier symbol should you land a pure wild win, and the Book also serves double duty as the scatter symbol, as is usually the case in ‘book slots’.

All symbols are represented on the bar above the grid, and random symbols get marked at random times in all stages of the game. The marked symbol becomes a special expanding symbol, and landing enough instances anywhere awards a full payline win. Landing the book at the same time as marked symbols gives you an additional marked symbol (the next tier above the current marked symbol), which can lead to more expanding symbol wins.

The Bonus Round triggers when you land 3, 4, or 5 book scatters anywhere in view, and this gives you 10, 15, or 20 free spins, respectively. You also win 2x, 20x, or 200x your stake up front from the triggering scatters, respectively, and you get the same number of extra spins during the feature should you land 3, 4, or 5 scatters in view. A symbol is chosen by the book up front to become the special expanding symbol, and the marked symbol feature can also trigger in the bonus round.

Finally, non-UK players, and anyone living in an eligible jurisdiction, can take advantage of the Bonus Buy option. It will set you back 125x your stake, and this guarantees 3+ scatters on the spin that follows. The Bonus Buy RTP increases to 96.65 %, at least on the highest tier setting.

The 200 Spins Book of Inferno Slot Experience

You get to see the marked symbol feature in action in the base game at least once, before we purchase the bonus round. It triggers around 1:30 into the 4:17-minute highlights video, and we got the minimum of 10 free spins. The number 10 was also the chosen symbol, and you can see for yourself how we fared by hitting the play button below.

Review Summary

There are only two ways to make a splash in the overcrowded ‘Book slot’ genre, and that is spectacular visuals or interesting feature twists. You get a mix of both in Book of Inferno, and Quickspin has paid so much attention to detail that we almost wish it was possible to read the diabolical book they have created. The elaborate pentagram the book emerges from is also a sight to behold, and there is no doubt that you find yourself in a rather nasty underworld.

The Marked Symbol feature has been seen before in different forms, but it’s still a great way to keep the base game more interesting than the dead spins grind you get in Book of Dead, for example. The 5,846x potential is a bit above the “standard” 5,000x you get in most ‘book slots’, but not enough to stick out in a spectacular way. Overall, Book of Inferno is a solid installment though, and the superb visual experience will probably attract attention from the many ‘book slot’ fans out there.
