Evil Devil

The top prize is capped at 10,000x your stake. On a $1 spin that is $10,000; on $0.20 it is $2,000. When the cap is reached the round usually ends immediately.

Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.

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.

The published hit frequency is 17.88%, meaning roughly one spin in 5.6 returns something — though many of those wins are smaller than the stake.

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).

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.

Multipliers

Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.

Respins

Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.

Split symbols

Symbols that count as two (or more) of the same symbol, boosting the size of combinations.

Sticky wilds

Sticky wilds stay locked in place for several spins or for the rest of a feature, giving every following spin a better chance of connecting wins.

Wild symbols

Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.

• 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 96.09% RTP, clearing $1,000 of wagering costs about $39.10 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.

For very high volatility we suggest a budget of at least 400 spins. This is what that means for Evil Devil (bets from $0.20 up to a maximum bet of $100).

Averages only: a short session can end far above or below them. Set a loss limit before you play.

Slots with the same mechanic (ways to win) and volatility (very high) as Evil Devil, with a higher published RTP. Casinos can still run lower versions of any of them.
