What are High Volatility Slots?
High volatility slots are games that pay out less frequently but when they do, they usually produce bigger wins.
In online gaming, volatility (also called variance) defines the frequency of wins a slot game is supposed to deliver. High volatility means lower win frequency, but in return for winning less often, you can expect higher than average payouts.
It all depends on what you prefer from your slot game. If you have the patience to wait it out, then these slots can be highly rewarding and they are likely to offer higher max wins than other slots too.

High Volatility vs. Low Volatility Slots
High and low volatility slots both come with pros and cons, it just depends on which playing style most suits you.
Some players need to see regular returns to keep them entertained. It’s understandable, no one wants to feel like they’re spinning endlessly, watching the bankroll slip away without getting anything in return.
Alternatively, some players dislike getting regular insignificant low value wins. They would rather wait it out in return for the chance to hit a big jackpot payout.
These are the key differences between High and Low Volatility slots:
Feature | High Volatility | Low Volatility |
---|---|---|
Payout Frequency | Low | High |
Average Win | Medium-High | Low |
Risk Level | High | Low |
Suitable For | High-Rollers, Risk-Takers, Short Sessions | Casual Players, Long Sessions |
If, on the other hand, you don’t care about volatility and just want to play slots that are packed full of entertainment, then our list of best online slots in the UK is worth checking out.
Who Should Play High Volatility Slots?
High volatility slots aren’t suitable for everyone. If you enjoy landing frequent wins through line hits or bonus rounds, then they’re definitely not for you. Players who do suit high volatility slots are those who:
- Have a large bankroll: Players with larger bankrolls and longer session limits are more likely to play these games as they have more time to wait for a larger payout.
- Chase big jackpots: On average, high volatility slots will have higher max wins than other games, so they attract players who want the thrill of a big win.
- Don’t mind losing streaks: Highly volatile slots suit players who don’t mind going on long losing streaks for a chance to get a big payout.
If you’re more interested in playing low risk casino games you can either select a low volatility title, or choose to play one of the highest RTP slots for UK players.
