Choosing some of the best payout slots is crucial to maximize your potential winnings. Focusing on high payout slots puts you in a better position if you wish to have more chances of winning something. These games are famous for having a higher RTP percentage and are (sometimes) also less volatile than the rest.
Speaking of the RTP (Return to Player), it is a crucial component when evaluating any slots or other types of casino games. This is the percentage of the money paid to the machine that is given back to the player as a reward. In other words, the higher the RTP, the better.
There’s a lot to talk about here, so keep reading to learn more about some of the best payout online slots UK.
What Makes a Slot High Payout?
A slot with a high payout is a casino game that allows players to win more money than the rest. Determining whether a given game falls into the category of a high payout slot is usually done by checking its RTP and some other parameters. Additionally, people who want to learn more about the best payout slots online can check options, such as the biggest winnings.
Here are some other factors that make a slot have a higher payout.
Payout Potential – Max Win, RTP, and Hit Frequency
We mentioned the RTP percentage, but this is not the only thing to check when evaluating the best payout slots. The maximum win is also essential, especially if you decide to focus on jackpot games. You can come across many slots, but not all have a high maximum of wins, so they may not be as interesting as those that provide this option.
Hit frequency is another key metric that many casino players forget about. Some people know it as a hit rate, and it is used to determine the likelihood of a slot hitting a specific combination that will land a payout. In other words, games with better hit frequency usually provide people with more consistent payouts.
Bonus Features
Alongside the best online slots payout percentage, RTP, and more, people should also check the games’ bonus features. Depending on the game, you can come across many different options, such as:
- Free Spins – This fan-favorite bonus feature allows players to play the game without using their money.
- Scatter Symbols – These special symbols can trigger bonuses such as extra rounds, free spins, jackpots, and more. Unlike regular symbols, these do not need to be in a single line to give you the advantage.
- Wild Symbols – When you land on a wild symbol, it can fill in the role of other symbols to help you win. Depending on the slot, the wild symbols can also have multipliers.
- Multipliers – Speaking of the devil, this feature will multiply what you have won while playing.
- Bonus Rounds – Some slots come with bonus rounds, which allow gamblers to play special mini-games. Each bonus round can be different, which makes a given slot much more interesting.
- Progressive Jackpots – Although casinos often classify progressive jackpot slots as a separate category, they are the same as their regular counterparts. The only difference is the potential payout, which increases with every bet.
- Picking and Clicking – This option has many names, but does the same thing. Slots that offer it allow you to reveal hidden prizes.
Volatility Level
Often called slot variance, volatility is a metric used to identify how often a slot machine will hit a winning combo and the average payout you could get. Alongside the RTP, volatility is among the key aspects to consider when checking the best payout slots.
Volatility is essential because it serves as a risk indicator. Games with high volatility usually offer larger payouts, but the winnings are not that frequent. On the other hand, lower volatility slots provide more frequent but smaller payouts.
Generally speaking, online casinos group their slots into different volatility levels. You can find Low, Low-Medium, Medium, Medium-High, and High volatility games.

Besides checking all of the critical data ourselves, we also monitor the software suppliers’ sites to ensure we are on the same page. This helps us select the best possible options.
