Best High Volatility Slots for UK Players
High volatility slots offer big-value payouts but with a low-win frequency. That means UK slots players can potentially bag significant wins, but they have to be prepared to wait for them. They are, therefore, ideal for players who enjoy a high-risk, high-reward strategy.
Packed full of thrilling bonuses, exciting features and huge potential payouts, its easy to see why they are popular. But they also require patience and a strong nerve. Our expert slots team have handpicked the best high volatility slots for UK players.
What Does High Volatility Mean in Slots?
High volatility slots are games that pay out less frequently but when they do, they generally 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 (and bankroll!) 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 which playing style suits you the most. Often, these highly volatile slots are used in slot tournaments due to the vast difference they can pay out from player to player.
If you’re a player who prefers frequent wins, regardless of value, then low volatile slots are right for you. Alternatively, if you’re a player who doesn’t mind going long spells without wins in the hope of a higher payout, then these slots are ideal for you.
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.

Gates of Olympus 1000 takes the original title and boosts its volatility, and max win!

Who Should Play High Volatility Slots?
These 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 larger bankroll: Players with bigger bankrolls and longer session limits are more likely to play these games as they have the time and money 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.
