This article should serve as a short guide to finding the best games from the thousands that are available online and will give you more information on where you can play these slots with the latest casino bonuses.

Best payout online slots UK list

Although it is by no means exhaustive, we've come up with a handy list of some of the best payout online slots that UK players can easily find at a number of online casinos. The below list includes those slots with the biggest win potential, and indicates the maximum win expressed by the number of times (x) relative to your original stake. So if, for example, a slot has a win potential of 10,000x your stake, this means that it is possible to win £10,000 on a single spin if you stake just £1 (keep in mind that is simply a possibility and is definitely not likely to happen on your next spin!).

Apart from the best payout online slots listed below, you should also check out progressive jackpot slots if you're after a big win. These don't have a fixed maximum win, but can end up paying out millions of pounds to lucky winners if the jackpot keeps increasing! You'll find all the information you need on our Progressive Jackpot slots guide.

Best payout slots Maximum win
Dead or Alive 2 100,000 x
Who Wants to Be a Millionaire Megaways  50,000 x
Temple of Treasure Megaways 50,000x 
Ivan and the Immortal King  40,000x
King Kong Fury 12,500x
Cazino Cosmos 11,821x
Vikings slot 10,000x
Blood Suckers 7,500x
Divine Dreams 7,414
Hall of the Mountain King  7,326 x
Dark Vortex 7,318x

Although the above slots have some of the best maximum wins possible, there are other factors that affect how much you are likely to win from a slot in the long term. Any experienced player would agree that it doesn't make sense to keep playing only in the hope of getting the maximum payout, since this is not likely to happen soon - what you're looking for is a slot that offers regular and decent payouts which help make up for any losing spins. Therefore, we also recommend checking out a number of other factors that make up the best payout slots, so you'll find a well-balanced slot that you can enjoy on a regular basis.

Factors that affect slot wins

Before we start with our tips on finding the best payout slots, it's important to be familiar with a few dynamics that characterise online slots. Slots are programmed differently so that the slot hit rate, RTP and volatility will vary from one game to another (unless the developer uses exactly the same program for two or more of its slots, in which case these will be exactly the same). It's these differences that you should use to your advantage in your hunt for the best payout slots. The below are the most important factors to consider:

RTP (Return to Player) - the game RTP is the percentage of the money staked that is returned to the players over time following a theoretical number of spins. This percentage is normally over 94% (you certainly shouldn't play slots with a lower RTP!), although most slots have an RTP of 96% or over. If the RTP is 96%, it means that over billions of spins, players will win back £96 for every £100 staked. Of course, this doesn't mean that you cannot lose or win more, since slots are a game of chance; you can win a jackpot after just 2 spins, or lose everything in a couple of rounds if you're not careful! 

To learn about the best online slots payout percentage, we suggest you have a look at our guide to slots with high RTP here.

Volatility - this is a term you'll encounter in all our slot reviews. Volatility, also known as variance, indicates how often players can expect the slot to pay out, and how big the wins can be. A slot with low volatility will award players with frequent wins for small or mid-sized stakes, while a slot with high volatility will provide players with much larger wins but much less frequently. For example, in slots with high volatility, it will be harder to trigger the bonus game, but the rewards when you do activate it will likely be huge and hopefully make up for a previous losing streak.

Hit rate - slot hit rate refers to how often you can expect to land on a winning combination while playing a slot. Some reviews publish this information to give you an idea of what to expect. Keep in mind that slots with a high hit rate normally pay out smaller amounts (which may sometimes be smaller than your original stake) to compensate for this payout structure, whereas slots with a low hit rate will pay out much less frequently but normally award much bigger prizes. Hit rate and volatility are therefore interlinked, as slots with a high hit rate will typically be classified as being highly volatile, and vice versa.

How to find the best payout online slots UK

Now that we've covered the factors that affect how slot wins are paid out, it's time to give you a few tips on choosing the best payout slots.

  • As we've already said, it's best to choose a slot with an RTP of over 96%, to ensure that the game is programmed to pay back to the players a decent amount.
  • It's also advisable to choose a game with a free spins round, since once you activate these free spins, you'll almost be guaranteed a profit, given that you don't have to stake anything to win. However, some of the best payout slots are those where free spins come with extra features, such as extra wilds, sticky wilds or multipliers. This will ensure that you'll win big from this round, especially if there's a multiplier involved!
  • Keep in mind that progressive jackpot slots have higher top prizes but may pay out less frequently, offering lower odds of winning overall. If you're after smaller but regular wins to maintain your bankroll, maybe it's best to go or low to medium volatility slots or for progressive slots that pay out decent amounts besides the jackpot.
  • Be cautious of video slots based on popular movies, or those featuring flashy, captivating videos. These tend to be entertaining and will appeal to fans of those movies, but typically pay out less than simpler games. Check a couple of online game reviews to see what other gamblers think about the slot you're thinking of playing to see if it's worth playing for real money.
  • Look for information about hit rate and bonus frequency. Some slot reviews will share this information, as will tools like Slot Tracker. Ideally, you're looking for a slot with a decent hit rate so you can play for longer and have a better chance of landing on a big win. 
  • Play the slot for free first - this is a great way of determining whether a slot is worth staking real money on and whether it's to your liking. A lot of online casinos offer this option; all you have to do is choose a slot from their list and click on 'play for fun' or 'play for free'. As you play, see whether you're happy with how often the slot pays out, as well as what the free spins round has to offer.
