Amongst the wide variety of online slots, finding the best payout slot machine online casino in the UK, is crucial if you’re looking to create a winning strategy for your gameplay. Some things to look out for:

  • Testing out games is crucial before committing.

  • Aim for a slot with a higher RTP rate

  • Look for top providers in the market.

Understanding Slot Payout Percentages

Slot payout percentages refer to the average amount of money that a player can expect to win back from a slot game over an extended period, compared to the amount of money they have wagered. In other words, it's the percentage of the total money wagered that a player can expect to receive back in winnings over time.

It's important to note that the payout percentage is an average, which means that it can't guarantee how much a player will win in a single session or even over a set number of spins. However, the more spins a player makes, the more likely they are to see their results align closer to the game's payout percentage.

How to Choose the Best Payout Slot

As players, we all aim to get the most out of our online slot experience, and this is more likely to be achieved with the best online slots. These games offer entertainment through their themes, graphics, soundtracks, and built-in features. However, they also provide the added thrill of potentially winning better payouts, which can make the overall experience even more enjoyable.

Our experts have shortlisted some top tips when looking for the next online slot game to place your wager on:

What is Return to Player Percentage in Online Slots?

Knowing the RTP rate of a game is a crucial factor to consider when choosing which game to play in a casino. Return to Player (RTP) is the percentage of all the wagered money that a slot machine or casino game will pay back to players over time. For example, if a slot machine has an RTP of 95%, it means that over time, for every €100 wagered on that machine, €95 will be returned to players in the form of winnings, and the remaining €5 will be kept by the casino as profit. So generally, the closer the RTP rate is to 100%, the better it is for players, as it means that they have a higher chance of winning

It's important to note that RTP is calculated over a long period of time, and it doesn't guarantee that a player will win back a certain percentage of their bets during a single gaming session. However, a higher RTP percentage does mean that the game is more likely to pay out winnings over time, making it a better choice for players who want to maximise their chances of winning. 

Higher is Better

Generally, slots with higher payout rates tend to have higher RTP rates. Different slot games from various developers come with different RTP rates. For example, Blood Suckers from Netent has an RTP rate of 98%, while 1429 Uncharted Seas by Thunderkick has an RTP rate of 98.5%. This means that the latter has a higher payout rate and is a better choice for players looking to maximize their chances of winning.

It's also essential to consider other factors such as the game's theme, features, and overall quality to ensure that it's enjoyable to play. By comparing different games, you can find the ones with the highest payout rates to maximize your chances of winning.

More Winnings, More Practice

If you want to increase your chances of winning more, practising and getting more familiar with slot games is a great idea. Most online slot sites offer demo modes for players to practice and enhance their gaming skills. We highly recommend taking advantage of this feature to improve your chances of winning.

In addition, using casino bonuses is another way to play the best-paying online casino games without risking your own money. Many popular slot providers offer games that are compatible with such promotions, which allows players to win real money that can later be withdrawn. By using these bonuses, you can also discover which online slots offer the biggest wins by playing them and seeing the payouts occur.

Slot Developers With the Best RTP

If you're looking for the best payout slots in the UK, one of the most effective strategies is to focus on slot providers with a track record of developing high-payout slot games. This way, you can narrow down your search and increase your chances of finding the best options.

Some of the top slot providers in the UK known for developing the best payout slot games include Pragmatic Play, NetEnt, Games Global, and RedTiger. Another useful approach is to read slot game reviews from our industry experts which can provide valuable insights into the best games available, helping you make more informed decisions.
