Our Guide to High RTP Slots

The key to this success is to find casinos with highest slot payouts to have you getting more bang for your buck. It means not wasting your time on a site that is unlikely have you winning and unfortunately there is a few of those about. Just stick with us and our list of the online slots with the highest RTP and you’ll be chasing the pennies in no time.

Best RTP Slots 2025

When it comes to working out which are the best paying slot games, you need to consider a couple of main things.The online casinos are bound to be bursting at the seams with new slots, but just because a slot is new, doesn’t mean it has what it takes to be one of the best paying slots out there.

Firstly, look at the RTP of your slot of choice to make sure you’re getting the most back on your investment. Ensure the software provider is reputable; a good reputation can only be earned. But at the end of the day, high RTP or not, you’ve got to be enjoying the slot or you won’t stick to it.

That’s why we’ve made sure to add a decent amount of titles to our list as it does come down to personal preference. Yes, you’re playing to win but what’s the point if you’re not enjoying the ride! Also, don’t forget that all the best payout slots in the UK are also available via the best UK slot apps.

What Is RTP Exactly?

When we talk about the Return-To-Player (RTP), we are looking at the best online slots which offer the highest winning chances. Let’s see more in detail how that works with a real example

• For example, let’s say you want to have a wee flutter of £100.
• Obviously, you want to be able to make that money work as hard as possible for you.
• If you play real cash slots that offer an RTP of 90%, then on average, you will win 90% of the time. If you play 100 spins at £1 each, you will theoretically come away with £90.

High RTPs Do Not Equate Automatic Wins

We are all aware that casinos are there as a business and a business can only survive by making money. So, having an RTP of more than 100%, which would guarantee you making some money every time, isn’t going to happen. So, what we look for is the casinos with highest RTP slots that are as close to 100% as possible. That means that your money is working as hard for you as it can. The other couple of percent is up to you, the way you play and Lady Luck.

What Can Be Considered as High RTP?

In general terms, the best real money online slots that you should be playing on, will have an RTP of over 96%.

• If the RTP is below this amount, we wouldn’t recommend wasting your time on it.
• That’s also why we generally avoid recommending slots that are based on big name movies or franchises.
• The developers have to pay a premium to the owners of the name and that money has to come from somewhere.
• Therefore, a lower RTP is applied to make up the difference. That means it’s you that pays and that’s not what you want.

Why Play Slots with the Best RTP

• You win more

Slots with highest RTP are going to have you winning more than those that are lower. This is obviously the average over many millions of spins and for the average Joe, one afternoon session won’t quite add up to that. But it’s still good to know if winning is your priority.

• Lower volatility

Other factors like variance or volatility also affect this rate, which we’ll go into soon. And just because one game has the highest RTP online slots doesn’t mean you’ll enjoy it more than one that is 1% lower, so do take this with a grain of salt.

• Better than land-based games

When compared to land-based casinos, slot machines in Las Vegas or similar will be around the 75% mark, which doesn’t sound too bad, right? Well, it is when you suddenly compare it to its online cousin which average around 95%. So why the difference? Overheads. Land-based casinos have huge electricity and staff costs to cover; online casinos run extremely efficiently.

Obviously, the remaining percentage is the profit for the business; the house always wins. But wouldn’t you rather play a high RTP slot game that has more chance of winning? You betcha! That’s why the online industry has been killing it over the years.

Volatility for Highest RTP Slots

Also known as variance, it relates to how often a slot pays out. The highest RTP online slots may also have high volatility which isn’t great news for players who play short sessions as the likelihood of a payout is less. But on the other hand, that also means that when it does pay out, it pays out bigger. Likewise, games with low volatility will see you hitting the jackpot more, but winning slightly less each time. So, which is better?

High VS Low Volatility

So, what’s better between high and low volatility? It comes down to the individual. Patience, whether you’re actually enjoying the game and your expected bankroll could all contribute to one way or the other. It’s like a progressive jackpot; the amount of times that Mega Fortune pays out is few and far between but when it does, it’s like winning the lottery. That’s because progressive jackpot slot machines have not just a low RTP, but they’re also incredibly high in volatility. It still makes them really popular though.

Make the Best of High RTP Slots

In order to maximize your chances of winning at slots games, it is important that you follow a few simple steps.

• Choose best payout slots with RTP over 97%. Obviously, playing slots with the highest RTPs will grant you more chances to win it all in the end! Browse our exclusive toplist to know where to play slots with the highest payouts.
• Beware of progressive slots. As tempting as those massive jackpots are, remember that progressive slots have very high variance, hence scoring a win will be far less likely. If you want to maximize your chances of winning, make sure you play at a high payout slot with low variance.
• Look out for bonus spins. Several of the best RTP slots offer a bonus spins feature where you can spin the reels for free. Thanks to this feature, your chances of winning automatically increase. Not bad at all!
• Practice the slot in demo mode. Make sure you get familiar with the mechanisms of your favourite high payout slot before you start playing for real money. Also, make sure you read the slot’s description carefully to make sure it has good hit rates and high frequency of triggering a slots bonus.

How to Find the RTP for Slot Games

Just like good casinos, the best RTP slots will always advertise just how successful they are. The old saying that “no publicity is bad publicity” doesn’t work in sales. Just like when you search for which casinos are licensed, that badge of honour is displayed right there on their homepage. If you find it tough to find the RTP for a specific slot, it’s probably very low.

As online regulations become stricter for casinos, it’s great news for players. Now-a-days, it’s the law for game providers to provide their RTP information so a quick search should get your solution in no time. And if slots with highest RTP are your priority, fear not; we’ve got you covered below.

Highest RTP Slots – Top 8

To save you the hassle of scouring the net for the best RTP slots, we’ve done the hard yards for you. These are the highest RTP online slots around:

1. Mega Joker – 99% RTP

This NetEnt game isn’t going to be everyone’s cup of tea. As video slots go, this lacks the bells and whistles of most but if it’s straight up winnings you’re after, Mega Joker is your horse. Ensure you play in Supermeter mode by keeping your bets to 10 coins and maximising your odds.

2. Jackpot 6000 – 98.8%

Another NetEnt classic, this is for the lovers of old-school amongst us. Bringing back the classic fruit machine vibe, your aim is land 3 jokers to guarantee the top prize. Again, to ensure the highest RTP available, keep it on 10 coins at a time.

3. 1429 Uncharted Seas – 98.6%

So, we’ve dropped two positions and only lost 0.4% RTP! There really isn’t much between the best paying slots. Thunderkick owns the 1429 Uncharted Seas slot – it’s based around an old sea-map theme with mermaids and giant squid as your symbols. Visually spectacular, it will also have your pockets full in no time.

4. Taxi Movida – 98.27%

A taxi-based slot from Booming Games, the incredible Taxi Movida boasts a crazy-high RTP rate of 98.27%. This game is loaded with bonus features such as expanding symbols, free spin rounds, a gamble feature that stacks up to 10 times and much more.

5. Marching Legions – 98.12%

A caricature of the roman empire by Quickspin, you’ll want to try and collect horns to move up the levels of waves. Making it to the fifth level can see you earning 5 marching stacks and an incredible 7,458x your stake.

6. Blood Suckers – 98%

Not since Twilight has vampires been so popular. This NetEnt gore-fest will see plenty of special features including wild substitutes, free spins and scatters. Trigger the bonus to unlock plenty of dead dudes in coffins to reap the rewards.

7. Jokerizer – 98%

Yggdrasil’s turn to get on our leaderboard and if you play this classic fruit slot machine style game in Jokerizer mode, you’ll hit the highest RTP. You’ll need to hit a winning combination first and choose to go for the higher payouts. It’s worth it, trust us, as are many Yggdrasil slots.

8. Starmania – 97.87%

Another great graphics game, this time from NextGen. Outer space themed and a cool soundtrack to back it up, this is a real sensory journey. It’s packed with out-of-this-world wilds and plenty of features to keep you occupied.

9. Kings of Chicago – 97.8%

Wrapping up our top 8 is this gangster poker game, again from NetEnt. Combining poker hands with classic video slots has paid off and this is a real crowd pleaser. Look out for the one joker to act as a wild and keep your coins on max to really reap the rewards. The lowest RTP on our list, but probably our favourite game.

How Important is RTP?

One look at our list of slots with highest RTP and you’ll notice that these 8 best RTP slots are separated by a mere 1.2%. To put that into perspective, that’s £1.20 for every £100 you invest. If it takes you two hours to burn through that much coin, was it really worth it?

RTP is taken rather seriously by the regulators these days too, who used to only check on a game as it was launched. Now, constant auditing is done on all aspects of a casino, including the software supplied by the game providers. We’re not saying they needed to be double checked, it just pays to be safe than sorry.

Our Tips for High RTP Slots

For us, the best RTP slots mean nothing if it’s not enjoyable to you. And what one player finds good is unique to the individual. Instead, why not look at the bigger picture and follow the following tips to getting the most out of your gaming, including the highest RTP slots:

• A casino license needs to be the priority
• Look for the best paying slots with an RTP of 97% or above
• Only play games you’re enjoying
• Manage your bankroll
• Try to use your favourite payment methods. PayPal slots for example are very popular in the UK.
• Only play at the best slot sites in the UK.
• Know when to stop.

Are Slots with High RTP Really Worth It?

We’re not saying that slots with highest RTP aren’t worth prioritising, not at all. But it’s all part of a structured gameplay that smart players need to take into account. Starburst is one of the most popular games of all time, has been for years. It didn’t make our list and may never do as its RTP is only just above 96%. But players line up to play it because it balances a high enough RTP with a game that is incredibly fun to play.

Types of Online Slots with High RTP

• Online fruit slots
• Win both ways online slots
• Hold and win online slots

Conclusion

• The best paying slots are the slots with highest RTP so you can get the best return on your money. It’s not complicated and is definitely something worth targeting if you are looking to churn through a high wagering requirement. But juggling the best RTP slots with their volatility and just how much you enjoy playing them is also something to consider.
• Also, take into account that the actual RTP is judged over sometimes a billion spins of a game so don’t get angry if your £100 only gets you £96.50 back. The next day you may get £102 back or more, you need to patient and play the long game.
• At the end of the day, if you’re not enjoying the slots with the highest RTP, is it really worth it? Online gaming is there to provide entertainment first and a profit second, so make sure you have your priorities straight.
