How to play Book of Inferno (members only)
Wins are paid when matching symbols land on an active payline, usually left to right starting from the leftmost reel. Your total stake is spread across the lines, and each line win is the line bet multiplied by the symbol's paytable value.
Book of Inferno is played on a 5×3 grid with 10 paylines.
- Set your stake. Choose your total bet per spin between $0.10 and $100. Wins are paid as multiples of this stake.
- Check the paytable. Open the game's info screen to see what each symbol pays and the exact rules for this version.
- Spin. Each spin's result is decided by a certified random number generator, independent of previous spins.
- Trigger the bonus. Land the required scatter symbols to start the free spins feature.
- Optional bonus buy. Where permitted, pay a fixed price to start the bonus directly.

How winnings work (members only)
What 96.15% RTP costs per $100 wagered, the 5,846x max win at a $1 stake

What 96.15% RTP means
Expected return = stake × 96.15%

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a very high volatility game.
Features explained (members only)
3 features explained: free spins, bonus buy, symbol upgrades
Free spins
A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.
Bonus buy
Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).
Symbol upgrades
Lower-paying symbols are transformed into higher-paying ones during a feature.
Strategy tips (members only)
- Size your stake to the volatility. Very high volatility means most spins lose and a large share of the return comes from rare big features. Treat it as entertainment with a strict budget and a stake of around 0.5% of your session budget or less. A simple rule: bring at least 400 spins' worth of budget, so a $50 budget suggests a stake of about $0.12.
3 more tips and a session planner
- Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
- Bonus wagering: at 96.15% RTP, clearing $1,000 of wagering costs about $38.50 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
- Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
