An Introduction to Book of Inferno
Anna the Explorer channels her inner demon huntress to fight off a trio of beasts hell-bent on crossing over into our realm. Their desire is to take over the world and change life as we know it, forever. Anna is guided by the Book of Inferno to track down her intimidating targets in the bowels of hell.
Surrounded by pools of lava and craggy shards of rock, the 5×3 reels sit within a hellish designed rock formation. Skulls stack up on either side of the reels and a befitting soundtrack plays in the background which adds to the drama.
Brave the fires of hell for a free spins bonus with retriggers. Watch the Book upgrade symbols to expand and pay anywhere. Spin for 5,846x maximum win!
Betting and Layout
The game’s layout is a regular 5 reels by 3 rows set-up, akin to most video slots. Wins are awarded by matching two or more symbols across the 10 fixed paylines. Betting options provide an average range of 0.10 to 100 credits per spin whilst the Book of Inferno RTP is 96.15%. This is a decent payout rate and is coupled with a high volatility.
It may take some time to land those bigger rewards but there’s a maximum 5,846x win up for grabs. For 125x your stake players can go directly through to the free spins bonus. It’s worth noting that the Bonus Buy feature is not available in the UK.
Visually the game is stunning with impressive graphics in deep and vibrant colours. Anna the Demon Huntress heads up the symbol table, closely followed by the Lord, the Lady and the Commander of Hell.

Gameplay and Features
Our Book of Inferno review discusses the free spins bonus in full a little further down the page. But first, let’s take a look at the other features:
Marked Symbols
Any symbol can be marked at random during a base game spin. You will easily spot them as they are surrounded by orange and yellow burning flames. Marked symbols will expand to cover the entire reel and pay anywhere without needing to be on adjacent reels.
Upgrade Expanding Symbols
If a Marked symbol lands at the same time as a Book, it will be upgraded by one to the next highest-paying symbol. If the Marked symbol is upgraded past the highest symbol, the lowest symbol is converted into the highest. This potentially creates more Marked symbols and expansions on the reels.
Regular Symbols
Like most video slots, the lower paying symbols are portrayed by playing cards A, K, Q, J, 10 and 9. These are designed in keeping with the sultry look of the hell-themed reels.
The mid-range symbols feature three gruesome characters; the Lord of Hell, the Lady of Hell and the Commander of Hell. Top of the paytable is our heroine, Anna the Demon Huntress.
Scatter Symbols
The Book symbol represents the scatter for the game. Landing three or more triggers the free spins bonus. How many spins depends on the number of Book symbols that land:
- 3 Scatters: 10 free spins;
- 4 Scatters: 15 free spins;
- 5 Scatters: 25 free spins.
Wild Symbols
Doubling as a wild is the Book symbol, it substitutes for all other symbols. The Book symbol is an ornate gold affair with artistic notations and drawings within. It also pays out for landing two or more on the reels for up to 500x your bet.
Book of Inferno Free Spins
Landing three, four or five Book symbols award 10, 15 or 25 Book of Inferno free spins. In addition, you’ll receive a win multiplier of 2x, 20x or 200x, respectively.
At the start of the free spins round a random symbol will be selected as the Marked symbol. The feature can be retriggered by landing a further three or more Book scatters.
How to Win at Book of Inferno
Matching two or more symbols across the 10 paylines awards a win. Landing Marked symbols will cause them to expand and pay anywhere without needing to be connected. Three or more Book of Inferno symbols activate the free spins bonus with up to 25 spins and a 200x win multiplier.
The best way to test out these exciting features is through a Book of Inferno demo. This is available at any of the recommended real money casinos named on this page. When playing for free at these regulated casinos, you can also collect deposit bonuses and other offers.
Payout Structure for Book of Inferno
The best payouts come from either the Book symbol or Anna the Demon Huntress. These award up to 500x your stake for matching two or more on the reels.
The Lord, Lady and Commander of Hell are mid-range symbols which pay up to 160x for matching five. For those lower payouts, the playing cards award a maximum of 12x your bet.
