Highest RTP Slots – Best Paying Online Slots in the UK

Do you know how much the RTP of online slots can have an influence on your winnings? Most players do not, and the result is often seen in inexperienced players disregarding RTP entirely while others exaggerate its importance and choose only the highest RTP slots.

Our goal here is to show the best paying online slots and their characteristics but also inform about how those details truly have an influence on your gaming and winnings.

After understanding how an 80% RTP differs from the highest RTP slots above 98%, you will be able to choose your online slots based on more than just the cute theme. Also, we will highlight the recommended online casinos in the UK filled with the truly best paying online slots.

How Does RTP Influence Winnings in Slots?

It is actually the slot features and characteristics that determine the RTP and not the other way around. The RTP, or Return to Player, is an estimation based on a real slot running test that considers millions, perhaps a billion of automatic spins. The average considering all the spins and winnings results in the RTP.

Therefore, a billion spins of games like Book of Dead, with a 96% RTP, would have resulted in a return of 96% of the total stake.

Does that mean that you will receive £96 back for every £100 you spend? Absolutely not. Not even another round of a billion spins would necessarily give that same average. It is only an estimation from a large sample and will never be totally reflected in real gambling.

Therefore, your £100 could become £0 over dozens of spins or actually turn a £1 spin into £5,000 within a single spin. Just use RTP as guidance, but do not only choose the highest RTP slots because you think other online slots are not worth it. Still, you can find excellent high RTP slots on this page that we would recommend playing even with a lower RTP.

What Is the Highest RTP Casino?

The fact is that the RTP of a casino is nothing else but the average of all games included, and that includes table games like roulette and blackjack sometimes. That said, we listed casinos based not on their casino RTP but on the availability of the best paying online slots on them:

Is It Worth Choosing the Best RTP Slots?

You can opt to play high or low RTP slots. It makes more sense to be truly interested in a combination of parameters rather than a single one. For example, a 95% RTP slot can have a high hit frequency and a tempting bonus feature and be worth a try, although that RTP is below the good average of 96%.

On the other hand, you can find excellent slot games among the highest RTP slots, listed below. 

The RTP of Jackpot Slots

Experienced players are aware that the RTP of jackpot slots tends not to be high. After all, most players will want their progressive prizes and do not mind lower returns during the base game. We want to show our point, indicating the real RTP of the game and what it becomes when the deduction to the jackpot pool is considered:

Progressive Jackpot SlotRTP With JackpotRTP With no Jackpot Deduction
Mega Moolah88.12%93.42%

Mega Fortune89.00%96.60%
Jackpot Giant91.24%94.22%

Still, none of them would have made it to the highest RTP slots. If your intention is to get a big prize and preserve high RTP, keep on reading to find games among the best paying online slots with prizes up to 200,000x your stake!

10 Best and Highest RTP Slots – 98%+

While 96% is the average for a good RTP in slots, some games fit into the highest RTP slots category. They have an RTP above 98% and are hundreds, but we selected the best and most varied providers to make sure you will find at least some of them on your favourite online casino.

Ugga Bugga – 99.07% (PlayTech)

Ugga Bugga has an impressive 99.07% RTP and is always featured on lists of the best RTP slots. PlayTech made it quite different from regular slots. The tribal-themed slot has only three reels and a single payline, similar to classic slots. However, you have ten different slots that can happen at the same time. After you spin the first one, you can lock symbols to occur on the other boards.

Book of 99 – 99.00% (Relax Gaming)

Released in 2021, Book of 99 has only recently made its way into the best paying online slots. It truly has a 99% RTP and Relax Gaming invested in its design. Using figures from Greek Mythology, it has a great free spin feature and a special expanding symbol feature, which help you get the prize of 5,000x your stake.

Play Book of 99, one of the best high RTP slots!

Mega Joker – 99.00% (NetEnt)

If you want to try a classic high RTP slot but Ugga Bugga’s system is not tempting to you, we recommend giving Mega Joker by NetEnt a try. It has an affordable bet value, 99% RTP, and you can try its demo here at Slots BetPlay. You can play from 1 to 5 paylines and might receive the chance to enable the supermeter, which extends the max stake value up to twenty times. Its design is quite simple, but people play it for the RTP and the supermeter mode.

Ooh Aah Dracula – 99.00% (Barcrest)

One of Barcrest’s high RTP slots, Ooh Aah Dracula, has 10 fixed paylines and stakes that can go quite high. The estimated return of 99% is perfectly tuned to situate players in the mood for a Dracula slot game, and you can even receive bonus spins that can generate high winnings. You can also count on Wilds to assist in combinations, of course, and get up to 5,000 coins with a single combination of the game’s logo.

Jackpot 6000 – 98.80% (NetEnt)

Players who have tried Mega Joker will notice similarities, mostly in the design, when they check out Jackpot 6000. NetEnt made it with a slightly lower RTP at 98.80%, but we suggest not really considering that worth your concern. It has 5 fixed paylines and three reels, similar to other classic slots from NetEnt and other quality providers. With only 6 symbols, this slot from 2014 can generate winnings up to 6,000 coins – that is where that name comes from.

1429 Uncharted Seas – 98.60% (Thunderkick)

Thunderkick has created one of the most known games when it comes to high RTP slots. The 1429 Uncharted Seas slot has a broad stake range from 0.10 to 100 coins, 25 fixed paylines, and a reduced jackpot of 670x in addition to the 98.6% RTP. You can also get 100 free spins during the bonus game, which is one of the features together with the expanding Wild. It only takes 5 Scatters to unlock 50 free spins at once – that is possibly one of the main reasons for it being one of the highest RTP slots.

Marching Legions – 98.12% (Relax Gaming)

Play with the Marching Legions and get 243 ways to win with a 98.12% RTP, which is decreased with a feature buy that is not allowed in the UK. In other words, we get to keep the high RTP. There is quite an affordable stake range of 10p up to £100 per spin, and the game has awesome graphics that match cool casual mobile games. Despite the high volatility, the chances of hitting a combination are around 25%, and you have a free spins feature available.

The Catfather – 98.10% (Pragmatic Play)

Pragmatic Play also has a considerably high RTP slot in our list, titled The Catfather. With only 9 paylines and a little pun on the name, The Catfather has a maximum winning of 2,251x and low-stake bets. Regular combinations do not pay much, so slot features like free spins and multipliers up to 4x are the justification for such a high RTP. Also, it is a low variance slot with frequent combinations.

Blood Suckers – 98.00% (NetEnt)

NetEnt has the biggest number of games in our best paying online slots list that considers the RTP. Blood Suckers is a highly popular one that, aside from a great 98% RTP, offers free spins and special bonus rounds. It has decent but classic graphics inspired by vampire stories. It is a game from 2013, after all, and that has its limitations. Stakes start at only £0.25 and can go up to £50 per spin.

Click here if you are brave enough to play Blood Suckers with a 98% RTP!

Jokerizer – 98.00% (Yggdrasil)

We will finish this list of the recommended highest RTP slots with this creation of Yggdrasil. Although symbols in Jokerizer are 3D and rich in detail, some players might notice it could have better graphics considering its provider. Still, it has a decent and tempting 98% RTP, prizes up to 6,000 coins, and a simple way of catching that jackpot with a single combination of Joker symbols. If they are scattered and out of the 10 paylines, that is still a 1,000x prize.

Best Paying Online Slots Vs. Highest RTP Slots

Some players have already decided by now that the best-RTP slots are also the best paying online slots. Unfortunately or not, that is not always the case. As previously said, the RTP is only one of the metrics available, and since slots are games of chance, luck has the biggest influence over them.

That said, to truly find the best paying online slots, we need to look at other parameters.

Hit Frequency and Highest RTP Slots

Hit frequency determines your odds of getting a prize when you spin a slot game. If a game has a decent hit frequency and high RTP, it means that it has frequent combinations with decent winnings. 

When you play for a considerable amount of time, the hit frequency does not matter that much. After all, one single win could easily generate winnings up to 200,000x in some slots. Still, you might want to get that figured out, especially if you are counting on winnings to continue spinning.

Payout and the Highest RTP Slots

Have you ever been caught by surprise and wondered how a single spin could have generated that much money? What about spinning lots of rounds to receive a prize that is much lower than your stake? Those are common experiences of slot players, and they have everything to do with a slot’s payout.

You might choose a 98% RTP slot on a bad day and not make many combinations of low prizes. Therefore, consider the payout table we disclose in our slot reviews to have an idea of how much simple combinations can provide you.

Variance and Volatility

The volatility of a high RTP slot varies a lot. You will find games among the best paying online slots that have high volatility and might get you a huge prize out of nowhere, while others will have frequent low prizes. While long-term playing tends to result in the same average, you have to find the type of volatility that matches your playing profile.

5 Best Paying Online Slots

Now that we know that choosing the highest RTP slots of 2022 is not enough to be playing the best paying online slots, let us look at slots with a great payout. All it takes is one lucky hit to get prizes above 100,000x your stake.

Starburst XXXtreme (NetEnt): 200,000x Stake

Starburst XXXtreme has a decent 96,26% RTP, which would already be enough to at least give it a try. However, you can win as much as 200,000x your stake that starts at 10p and goes up to £50. Only 9 paylines, high volatility, and a complete redesign of the popular Starburst game by NetEnt really make the slot live up to its name. 

Win up to 200,000x your stake now!

Peking Luck (Pragmatic Play): 180,000x Stake

Peking Luck gives you the chance of winning up to 180,000 your stake, offers in-game multipliers up to 18x, and even up to almost 40 free spins at once. There is no question as to the quality of a slot by Pragmatic Play, even if you do not manage to combine all the features for maximum winning.

San Quentin XWays (Nolimit City) – 150,000x Stake

Looking for odds of 1 in 230 of activating special free spins and the chance of winning 150,000x your stake? The provider NoLimit City has a high-quality and well-designed game among the best paying online slots, named San Quentin XWays. It carries an RTP of 96.03%, on the right average, and the gameplay is quite addictive.

Robin: Nottingham Raiders (Peter & Sons): 121,500x Stake

It is not common to see slots from Peter & Sons featured among the best slots in the UK because of the volume of games from other providers. However, their title Robin: Nottingham Raiders with an RTP of 96.09% made it to this list thanks to its maximum win of 121,500x the stake, which starts at 20p and goes up to £50.

Play Robin: Nottingham Raiders here!

Wild Flower (Big Time Gaming): 114,000x Stake

Big Time Gaming is well known for its Megaways slots, and it made its way into our list because of Wild Flower, one of the best paying online slots in the UK. It has an impressive 4,096 paylines – still far from the Megaways technology – and an RTP of 96,52%. That does not make it to the highest RTP slots, but it does not need to with a 114,100x maximum win. If you win the maximum during the base game, it goes up to 46,100x your stake, which is still decent.

How to Calculate RTP in Slots?

As previously mentioned, the RTP of a slot game is calculated based on a very long sequence of spins. Some providers like Quickspin test the game for up to 1 billion spins. Then, the total amount returned is divided by the total amount stake to generate the average based on statistics.

If the average spins were worth £10 and the average return was £9.50, we are talking about a 95% RTP slot. That is because £9.50 is 95% of £10.


Is There a 100% RTP Slot?

The only way to have 100% as the average return would be if all spins would return winnings that match the stake. In other words, that would be impossible.

Can I Win More With the Highest RTP Slots?

Theoretically, yes. However, the biggest single prizes are not found in the highest RTP slots, as proved above. In the end, play games with a good RTP that are fun and hope to be lucky.

Does a Higher RTP Mean I Will Win More?

No, it means that the test resulted in more winnings when compared to the average slot. Your gameplay can always be an exception upwards or downwards.

How to Find the RTP of a Slot?

Most online casinos will not provide the RTP of the slot. Instead of accessing the provider page to look for a specific game, find all your favourite slots and their characteristics, like the RTP, here on the website.
