What We Think
The part of Book of Inferno worth your attention is the Wild Symbol. It gives the Underworld Hell theme something to do beyond the spin button, and it is where most of your bigger results will come from.
At 96.15% RTP it sits above the 96% mark many players use as a reference point. Trying the free Book of Inferno demo is a low-risk way to judge whether the high-variance swings suit your style before you wager real money at the best payout casinos for UK players.
What Makes Book of Inferno Different?
The Wild Symbol is the feature that separates it from the rest of Quickspin's Underworld Hell range.
If that style appeals, you can browse the licensed UK slot sites to find somewhere to play for real money.

How Book of Inferno Plays
Book of Inferno is a five-reel slot from Quickspin. With high volatility, wins land less often but carry more weight, so the bigger moments tend to come from the features rather than the base game.
Stakes run from £0.10 to £100 a spin, so it suits a range of bankrolls.
Book of Inferno Bonus Features
The features that shape Book of Inferno are:
- Wild Symbol
- Free Spins
- Buy Feature
Each one feeds into the bonus side of the game, and the Wild Symbol in particular is where the 5,846x your stake top win becomes possible. If the bonus round is the draw, it is worth exploring free spins no deposit UK offers.
Book of Inferno RTP and Volatility
Book of Inferno runs at an RTP of 96.15% with High volatility, and the maximum win is 5,846x your stake.
That return sits just above the 96% reference point, and some operators run lower RTP variants, so check the game menu before playing.
The 5,846x your stake ceiling reflects the high variance: this is a slot that pays through its features rather than steady base-game wins.
Book of Inferno vs Big Bite
Book of Inferno and Big Bite are worth putting side by side, even though they take different themes, because the RTP, volatility and top win are where your choice really comes down.
| Feature | Book of Inferno | Big Bite |
|---|---|---|
| Provider | Quickspin | Push Gaming |
| RTP | 96.15% | 96.33% |
| Volatility | High | Medium |
| Max Win | 5,846x your stake | 10,000x your stake |
| Theme | Underworld / Hell | Arctic fishing with cartoon animals |
If those numbers suit you better, try the Big Bite demo.
Who Should Play Book of Inferno?
Book of Inferno is a good fit for:
- Players who enjoy Wild Symbol-style features
- Players comfortable with high variance and longer dry spells
- Fans of Quickspin and the Underworld Hell theme
Look elsewhere if you want frequent, low-variance wins. In that case, browse the new-to-market operators for a calmer option.
Final Verdict
Book of Inferno earns a 6.8 from us. The Wild Symbol gives it a clear identity, the 96.15% RTP is a strength, and the high variance is the thing to weigh before you play.
For an Underworld Hell slot with a big top end, it is worth a spin on the demo first. Players who like the theme should also try the Big Boom Riches demo.
