Best High Volatility Slots for UK Players
High volatility slots are perfect for players seeking thrilling spinning sessions, with a high-risk, high-reward approach, but they aren’t for everyone.
These slots require patience so they need to be packed with exciting features and valuable rewards to make them worthwhile. Our expert slots team have handpicked the best high volatility slots available for UK players, based on their gameplay, bonus rounds, and payout potential!
What are High Volatility Slots?
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 high volatility 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 something juicy.
Let’s take a look at some of the main differences between these 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 you’re looking for great all-round slots regardless of volatility then our list of best online slots in the UK is worth reading for unbiased reviews.
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 probably not for you. Players who do suit high volatility slots are those who:
- Have a large bankroll: slots with big win potential can be less rewarding in the short term, with bigger payouts being rare. Players with larger session limits are more likely to play these games comfortably.
- Chase big jackpots: On average, high volatility slots will have higher max wins than other games, attracting lots of players.
- 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 games which usually allow you to take part in long sessions, you can either select a low volatility title, or one of the highest RTP slots for UK players.
