Book of Inferno - What you need to know
If you like “Book of” slots, such as Book of Dead, you’ll find many similarities in this slot. The mystical world of the Book of Inferno slot takes place within the underworld. This 5-reel, 3-row slot offers 10 fixed paylines - and you can hit those wins by landing 3 or more symbols from left to right. With the high-paying symbols, only two are required for a win. There is a "Pay Anywhere" feature but this is only active when the Marked symbol feature is triggered. In standard play, this is a classic 10-payline slot paying from left to right.
Sitting inside the reels, you‘ll see plenty of devilish symbols - apart from the A-9 playing cards; you have the higher-paying characters, including the Commander of Hell, Lady of Hell, Lord of Hell, and Anna the Demon Huntress. Then, of course, we have the Book symbol that acts as both Wild and Scatter - substituting for other symbols and triggering Free Spins if you manage to land 3 or more on the reels at once.

Bonus Rounds in Book of Inferno
The Book of Inferno offers some excellent bonus features, including the Marked Symbols and Free Spins bonus round.
Marked Symbols
If a marked symbol lands anywhere on the reels, then it will expand to cover the whole reel - and it can pay from any position on a line. Unlike standard symbols, it doesn't need a left-to-right alignment to land a win.
However, if a Book symbol appears alongside a marked symbol, the marked symbol will be upgraded by one level, which can lead to more marked symbols and even more expansions. If the marked symbol has already been upgraded to the highest level, the lowest symbol on the grid transforms into the highest symbol.
Free Spins Feature
If you manage to land 3 or more Book scatter symbols anywhere on the reels in the base game, then you will trigger the Free Spins round. The number of free spins you’ll get will depend on the number of Book symbols you land:
- 3 Books gives you 10 free spins.
- 4 Books will give you 15 free spins.
- 5 Books will offer you 25 free spins.
Before the free spins start, a random symbol will be chosen as the marked symbol - and it behaves similarly to the base game. You are also able to retrigger the Free Spins feature - with the same number of extra free spins awarded.
