Looking for the best RTP slots is quite a hassle – most casinos do list it, but don’t give you the option to rank the games according to it. Many experienced players also have certain preferences towards the software studio that has provided the game. NetEnt, Microgaming and Playtech are the most recognisable and trusted brands, but there are also niche studios that have some hidden gems.
However, to be sure in the RTP that is published, it is important to play in a licensed casino that has passed all the necessary inspections for your region. As UK players, for instance, we always check the validity of the UKGC license for the casinos that we review on our website.
Down below, you can find the highest RTP slots we have found, and the rest of our top 10 – as well as links to casinos where the RTP is verified to be genuine and provide a 100% bonus on your first deposit and the max bonus can be as much as £300.
As you can see, there are quite many oldies and even some notable titles that couldn’t make the list of high RTP slot games, such as Kings of Chicago, Blood Suckers, Book of Dead, and Rainbow Riches, despite being great headlines with bonus spins and high variance.
There are new online slots coming out constantly, and we do try to keep our listings up-to-date, but the recent trend in slot games has been towards declining RTP levels – nothing has broken into our top 10 rankings since 2015.
You should also keep in mind that the RTP isn’t the only factor you need to consider when choosing among the best payout slots for your session. Pro slot players are definitely aware of the detailed mechanics of slot RTP, but they also check other things like the variance of the game. Low variance and high variance can be a deal-breaker when combined with the best paying slot games.
What Is RTP and Why Is It Important?
The Return to Player rate is the favourite thing of all slot players – but what does it mean, exactly? If you like to hang out in land-based casinos, then you would hear about average RTP and house edge all the time. The RTP is a theoretical value that shows what portion of the total bets made into the slot will be returned in the form of winnings. Since the RTP is an officially published value, all slot machines have to pass a strict inspection whether their RNG engine complies with these values. In all our reviews, we always dig out the return to player percentage of the games and list it clearly.

The RTP is the best measure of the potential profitability of a slot that we have. However, you should keep in mind that it is a long-term value – it can only be measured over a long number of spins. This means that an RTP of 98% means that for every $1000 wagered, the machine will return $980 as winnings – but over the course of a month or even longer. This doesn’t mean that this result is guaranteed over a short session of, say, 100 bonus free spins.
The RTP shows us the fine margins in our odds to win in a game. Since all slots have to give out their portion of winnings over time, a higher Return to Player percentage indicates a bigger chance to land a winning combination. This is never a stone-clad guarantee; RNG engines nowadays are getting more and more complex.
So to predict them, we would need a tonne of data we can’t get. However, knowing the online slots with the highest RTP is the first step in successfully influencing the luck factor and improving your odds of beating the one-armed bandits! Furthermore, gathering info on whether the game is of low variance or high variance also gives us an advantage.
What Are the Good RTP Levels?
OK, so now we know that with slots RTP, higher numbers are better – but what levels constitute ‘high’? Well, as we already said, that is strongly subjective – but as a rough guideline, most slot players ignore any game with lower than the average RTP of 94-95%. Slots generally have a lower Return to Player rate than card and table games. They are more luck-based, unlike blackjack casino games which are famed for the highest RTP.
If an online slot has a theoretical RTP over 97%, then it is definitely a keeper – but as you can see from our top 10 best RTP slots list, this is not a common occurrence. There are often other things we need to consider when choosing a slot, so anything over 96% is a good compromise if you want better graphics or more exciting bonus features, free spins, and higher max bets. And you should always remember that progressive games follow a totally different set of rules.
House Edge vs RTP – Are They Different?
Mention RTP and House Edge in the same sentence, and you would confuse most casino newbies. The numbers are radically different – but they show you the same thing. In fact, the house edge is the opposite value of the RTP rate. It shows what portion of the total max bets will remain in the machine and be kept from the casino or proprietor as a profit.
For instance, if the slot has an RTP of 97%, it will give out 97% of all wagers as winnings – then the house edge should be 3%, and 3% of the max bets will remain with the casino. Most online casinos prefer to list the ratio, where you should be aiming at the highest RTP slots, but with a house edge, lower values are better. As rough guideline, anything over 5-6% should ring alarming bells in your head – unless it’s for a progressive jackpot slot.
Is Online Slot RTP the Same Everywhere?
With gamblers, there is always a niggling doubt burning in the back of their minds. Am I being cheated? With online slots fans, the Return to Player rate is the measure of whether a game is fair or not. We often pick our slot games based on the publicised RTP rates, especially if there is no further data available. If the casino has passed the necessary inspections, then all games will have an accurate RTP that is published.
The casino operator will be punished by law if they advertise false RTP. Then, you have the developers having completely different strategies on the subject of RTP. Some games, like the slots of Thunderkick were naturally created with a high RTP. In contrast, others emphasise jackpots or simply are designed to have high volatility.
However, there is something you need to be aware of. Recently there was a small controversy with the Play n’Go software provider – diligent players discovered that a game could have different RTP rates at different casinos. The software studio offers several different levels for RTP, and the casino is free to choose one of them. Some of the top Pariplay casino sites also offer plenty of high RTP slots, as well as low payout titles from the same provider.
As of 1st of September 2016, the United Kingdom Gambling Commission requires all online operators to check the RTP of their games in advance and to monitor the performance of the games during real-time play. The slots at these casinos have also passed inspection by eCOGRA – you might be sick of their logo, but as we’ve said numerous times, this is the top testing house that we trust.
Other Slot Characteristics
To truly evaluate a slot game, players need a lot of data which is gathered over the course of hundreds if not thousands of spins. That’s why you can use deposit bonuses such as 50 free spins on the best payout slots for risk-free tests. Casino pros track the hit percentages and, based on that, try to determine the volatility of slot games.
The high volatility describes what result you can expect from your individual session much more correctly and gives you a better idea of how to budget your bankroll. Coupled with RTP, variance helps us pick slot titles closer to what we want. However, even then, the unpredictable nature of the RNG modules ensures that your individual session might deviate from expectations.
Progressive Jackpot RTP – Why Is It Always So Low?
If you have some basic knowledge about slot RTP, then you have probably noticed that progressive jackpot slots always have lower RTP rates than other titles, except Mega Joker which boasts an insane 99%. For instance, Mega Moolah is one of the most popular progressive slots in the world with over 100 bonus jackpot wins since its release, but it also boasts one of the worst RTP percentages you will find online. This isn’t done by coincidence, but by design.
In jackpot networks, a portion of each bet placed goes to the progressive pot, increasing the size of the grand prize. This means that the base games in progressive slots pay off worse, while the accumulated jackpot goes to a single lucky winner. In RTP terms, the jackpot is called ‘progressive contribution’ – a slot with an RTP of 91% and a progressive contribution of 5,8% will have an actual RTP of 96,8%, but 5,8% of all winnings will only be given out in the form of a jackpot prize.
What Else Do You Need to Know?
RTP is an important metric, but slots have been getting more and more complicated in recent years – or people have simply been digging more due to their increased popularity. Players are trying to understand high RTP slots and control their luck to a certain degree – well, not really, slots are notoriously luck-based, but every little edge can make a difference. If you want to learn everything there is to know about the best online slots – and some of the things you don’t really need to know – then you should take a look at the next parts of our slot article series. Furthermore, for practice purposes, there are many free slots UK players can play and enjoy.
