If there’s one thing UK players like more than playing thrilling slots, it’s playing thrilling slots that are known for paying out money. In other words, they like playing the highest RTP slots and best RTP slots in the UK.

There are thousands of online slots available for British players to enjoy, and every one of them has an official RTP (Return to Player) percentage. This percentage represents the approximate win rate a player can expect to achieve. In essence, the higher the RTP, the more often a player is likely to win.

Both classic slot tiles and new releases can have high RTPs. These slots can also have varying themes and features. Since there is no one-size-fits-all when it comes to the highest RTP slots in the UK, we’ve done the research for you to help you find the best slot machines to play at the top online casinos.

What is slot RTP and why it matters

Before we dive into the highest RTP slots for this year, it’s important to know why we’ve selected these games by first understanding a bit about RTP and how it can affect the games you play.

RTP is expressed as a percentage - Every online slot machine has a Return to Player percentage (e.g. 88.12%, 95.4%, 97%, 98.05% etc.), which is also sometimes referred to as a slot’s payout ratio or payout rate. The higher the percentage, the more a player can expect to win over a longer period of time. Naturally, this is why the best payout slots in the UK that we’ll discuss below are frequently sought out by players.

RTP provides insight into the game’s house edge – A slot’s house edge is its RTP subtracted from 100%. This means the house edge of a slot with an RTP of 97% is 3%. This house edge is what provides the online casino with the necessary mathematical advantage that ensures their business a profit over the long term.

RTP can increase when bonus features and jackpots are present – You might notice that most progressive jackpot slots have lower RTP rates than online slots without jackpots. This is because a portion of the RTP for these games is reserved for the jackpots. For instance, Microgaming’s popular Mega Moolah slot has an RTP of 88.12%. However, this RTP rate bumps up to 93.4% when you enter the Jackpot Bonus Round.

RTP percentage can vary from one casino to another - A slot machine’s original RTP is determined by the game developer or supplier. That said, it can sometimes be legitimately changed by an online casino operator in certain circumstances, such as to make more money from games or to cover costs due to changes in tax laws. This is the reason why you might come across two different RTP percentages for the same game offered by two different online casinos.

FAQs About Slot RTP

What is slot RTP?

Slot RTP stands for Return to Player. It is sometimes referred to as a slot’s payout ratio. RTP is displayed as a percentage that indicates a player’s estimated theoretical return over the long term. In essence, the closer a slot’s RTP is to 100%, the more it will pay out over the long haul.

How is RTP in slots calculated?

RTP percentage is calculated by the total number of a player’s wins divided by the total amount a player wagers. A game’s RTP rate is not calculated by 1 single spin. It is calculated over hundreds of thousands, millions or even billions of spins on average.

How to find the best RTP slots and What online casino has the highest RTP?

The UK Gambling Commission requires online casinos to post the RTP percentage of each game they offer. Some casinos will provide a list of all their game RTP percentages for quick reference. However, most RTP can be found in the slot’s paytable, information, or help section. Most video slots have an RTP rate of 95% or higher, with anything 96% and up considered to be high.

What’s the Difference between slot variance and RTP?

Slot variance is the measure of risk. It suggests how frequently or infrequently a player can expect to win while paying a slot and how big or small they can anticipate payouts to be. RTP percentage is the estimated theoretical outcome of playing tens of millions of spins.

Quick guide to safe and responsible gambling

A big part of enjoying the most gratifying slots experience online is ensuring that you’re always playing responsibly. Here are ways that you can help yourself stay in control of your real money gambling:

Set limits – Create deposit limits, bet limits, and win and loss limits to help ensure you avoid betting more than you initially intended or more than you can afford to lose.

Take breaks – Set play limits to ensure you don’t lose track of time. When on a break, completely sign out of the casino and do something else.

Don’t chase losses – Even the highest RTP slots do not guarantee a win. Your odds of winning never change, even if you hit a losing streak. Once you’ve hit your loss limit, stop playing for the day.

Play with a level head - Avoid playing when you’re emotionally high or low or if you’ve taken substances (e.g. alcohol, medication, etc) that alter your behaviour or mood.

Self-exclude if you need to – If for any reasons you feel, suspect or are worried that you may have a gambling problem, don’t hesitate to take a long-term break from playing.
