10 Best High RTP Slots In The UK 2023

British gamblers have access to a massive library of online slots across the best casino sites. They vary significantly in almost everything, including payout rates, volatility, special symbols, and bonus features. Below, we present the highest RTP slots to play in the UK:

Book of 99

Book of 99 Slot

Book of 99 was launched in 2021 by the popular provider Relax Gaming. It has an outstanding payout percentage of 99% and like many of the highest RTP slots boasts high volatility. Players will love the cartoonish Greek Mythology theme and the sage developing on a 5x3 board with 10 fixed lines.

The bonus round requires the collection of 99 scatters, but it promises to be quite lucrative. Free Spins is played with a special expanding symbol that will pay independently if enough in number on the grid. The bonus can be started in the usual way by landing 3 or more wild. Book of 99 features a max win of 12,075x the bet!

Thrones of Persia

Thrones of Persia Slot

The next title in our best RTP slots overview was released in 2016 - Thrones of Persia. The highly volatile machine has an RTP rate of up to 98.83% and a maximum prize of 5,470x the wager. The 5-reel grid is placed on top of the ancient city, and players can activate up to 20 variable lines.

Needless to say, you'll need every single payline to take advantage of the excellent RTP. Tom Horn Gaming, the software provider, has added extremely high-valued symbols in the Paytable, including wilds. The bonus round is a Free Spins minigame with special win multipliers.

1429 Uncharted Seas

1429 Uncharted Seas Slot

The 1429 Uncharted Seas is another marvelous game launched some time ago. It was developed by the renowned supplier Thunderkick and launched in 2014. Unlike the previous high RTP slots, it is a low volatile machine but boasts an incredible RTP of 98.50%. However, the variance has left its mark, and the max win is only 670x.

The map-styled grid has 5 reels, 3 rows, and 25 lines, and Thunderkick has created a masterpiece in terms of drawings and visual effects. Five scatters in view deliver 50 free spins and additional retriggers are possible. Both the main game and bonus round are played with expanding wilds.

Madam Lucky

Madam Lucky Slot

Madam Lucky is also among the highest RTP online slots on the market. It was introduced in July 2023 by the skilled provider SYNOT. It's not a progressive jackpot slot, as many have expected, and actually comes with a pretty basic bonus set. However, the Return to Player rate reaches 98.15%.

Moreover, Madam Lucky is characterized by medium to high levels of volatility and has a top prize of 3,500x the stakes. The bonus package includes a Gamble Game, with up to 10 consecutive plays and the option to cash out half of the sum. There is a Free Spins bonus as well with all payouts tripled.

Triple Bar

Triple Bar Slot

Triple Bar is a classic one-handed bandit with only 1 payline. British players only need to land winning symbols in a row on all 3 reels to get hefty prizes. The title was launched in 2021 by 1X2gaming and boasts beneficial medium variance. Despite the very small jackpot win of 40x, the machine has a place among the best RTP online slots!

The reason is that Triple Bar boasts an RTP of up to 98.15%! Moreover, it lacks any bonus features and ante bets, which may distract players from their main goal - to win cash. There are only 3 potential combinations on the board, and they pay 4x, 8x, and 40x the bet.

Marching Legions

Marching Legions Slot

This incredible cartoonish slot features a Roman theme and engaging gameplay. It came out from the factories of the famous gambling provider Relax Gaming in 2020 and offers a max win of 10,000x! Furthermore, it's among the best online slots with the highest RTP due to a rate reaching 98.12%.

The Marching Legions is played with 243 ways to win on 5 reels and 3 rows. There are a number of exceptional bonus features which will make you quickly forget the absence of wild symbols. Besides the Nudge, Respin, and Bonus Buy, Relax Gaming has added Free Spins with stacks of legionaries.

Multi Bricks

Multi Bricks Slot

Earlier in 2023 SYNOT released Multi Bricks - a low to medium volatile slot machine with a brilliant RTP rate of up to 98.10%. The top prize is not bad - 500x the bet, but what counts is the gameplay. Essentially, it's a 3x3 classic slot with a fascinating design and 5 paylines.

However, during the Free Spins minigame, players can count on 27 ways to win. Moreover, wilds land with win multipliers of up to x3 and multiply each other for a max multiplier of an astonishing 27x. SYNOT has added its Gamble Game, too!

Money Cart 2

Money Cart 2 Slot

If you enjoyed the Money Train series, Money Cart 2 will blow you away! In 2021, Relax Gaming released a cut-off version of its masterpiece. This one represents the bonus minigame only and fits among the highest RTP slot games because of its extremely high rate of 98%.

Money Cart 2 is a highly volatile slot machine, offering a top win of 5,000x. It's played on a 5x4 grid, which expands up to 7x4 and with Hold & Win mechanics. Players can stake from 10p to £200 per spin. The gameplay includes 9 bonus modifiers, including the persistent Payer, Sniper, and Collector.

Blood Suckers

Blood Suckers Slot

NetEnt released its Vampire-themed masterpiece back in 2013, but the game is still played by many British slot enthusiasts. Blood Suckers is a low volatile machine with a 98% RTP rate. It's played on 5 reels, with 3 rows and 25 fixed lines. Bets vary from 25p to £50 per spin, and the maximum payout is 900x.

Blood Suckers is not the slot machine with the highest RTP, but offers scatter wins, free spins with retriggers, and a bonus game. It looks great, and the gameplay is surprisingly fast and smooth, given the date of release. In 2017, NetEnt came with a sequel, but the original remained players' favorite.

Orca's Wild Bonanza Extenda Edition

Orca's Wild Bonanza Extenda Edition Slot

Fans of the sea-inspired casino games will definitely love Orca's Wild Bonanza Extenda Edition. It was introduced to the gambling audience only a few weeks ago, in September 2023. The grid consists of 5 reels and 3 rows, and players can use 25 fixed lines to collect payouts.

Orca's Wild Bonanza Extenda Edition is a game of Boomerang Studios and boasts high volatility and an RTP of up to 97.97%. Players can win 12,500x their stakes via the cascading reels and WinMulti multiplier. The Shell can change symbols into lucrative wilds, and the bonus game here is Free Spins.

What Is RTP?

Return to Player is an indicator and term describing the payout potential of an online casino game. It shows the percentage of total bets that will be paid back to the player. Essentially, it's a theoretical indicator, and the actual RTP will be fulfilled over a prolonged time that can't be predetermined.

The best online slots with highest RTP slots boast rates between 97% and 99%, but most of the reel machines out there have RTPs from 94% to 96%. As a rule, players should avoid games with percentages below 94% unless there is a good reason for that, like progressive jackpots. The RTP rates are usually calculated over tens of millions of spins!

Why High RTP In Slots Is Important?

Seasoned gamblers are well aware that the overall productivity of a casino game does not depend only on the payout rate. However, the high RTP slots are much more appealing to players because they are guaranteed to provide more returns in the long run. The higher the rate, the higher the winning chances! Here are more reasons to choose high-RTP slots:

Better Odds For Players

The odds are all that matter in online gambling and sports betting. There is nothing for sure when you are placing bets, but the higher RTPs support gamblers' hope. The better RTP is a kind of insurance, especially if combined with mild volatility and a proper betting strategy.

Value For Money

One thing is certain, the highest RTP slots provide better value of your spent money. Even if you don't end your session on profit, you will know that you made the right choice. The better-paying games deliver more happy moments and improved entertainment overall.

Longer Play Sessions

Continuing the above thought, the high-paying reel machines provide longer playing sessions, too. Even if you lose on the average, the pace is lower, and your budget will be enough for more spins. This also includes the chance of triggering a bonus feature or winning a jackpot prize.

Longer Play Sessions

Risk Reduction

Like any other casino game, slots are played in favor of the House. However, those with high RTP coefficients boast very low casino edge. For example, Book of 99 has an RTP of 99%, and respectively, the House advantage is a slim 1%, which is comparable to blackjack - the highest-paying gambling game!

Increased Chances Of Meeting Wagering Requirements

One of the best ways to play games in the UK is by using a fair and advantageous casino bonus. However, many of them come with wagering requirements, which must be met in order for the winnings to be converted and become withdrawable. By choosing the highest RTP online slots, players will be facilitated to do so.

Potential For Bigger Wins

The good RTP rate combined with medium or high volatility is the best prerequisite for winning massive prizes. The respective slot machines are developed to drop these big wins every once in a while, and playing for longer increases the odds. Of course, the high RTP should not be confused with the size of the prizes.

Greater Player Satisfaction

In general, if you win more frequently, you'll feel more excited and engaged. You'll be able to make the most of the game and experience the special features. The slots with high RTPs are a great opportunity for novice gamblers or low rollers seeking entertainment rather than profits.

How We Rate The Best RTP Online Slots

Gambling has been going through a major boom in the last couple of decades. The number of online casino games has drastically increased, and British players have a huge choice of titles. In the following paragraphs, we’ll introduce the main factors for rating of the best RTP slots:

RTP Value

First, of course, we check the RTP rate and sort the games in descending order. The highest-paying machines have rates up to 99%, while on the other end, the value can drop down to 85% and even lower. Still, there are some tempting titles in that part of the range, holding progressive jackpot pots.

Volatility/Variance

It's not enough for a slot to have a great RTP in order to be in our ranking. Volatility is critical, too, because it determines the size of the rewards and their actual frequency. For example, the low-variance slots pay more frequently but smaller prizes, while the extremely high-variance titles may award gigantic payouts.

Volatility / Variance

Reputable Software Provider

The highest RTP slots are always developed by top-notch developers, like NetEnt and Red Tiger. We always check the origin of the titles in order to be sure that the displayed RTP rates are true and fair. All reputable iGaming providers are certified and audited by independent agencies like eCogra.

Player Reviews & Feedback

We also check and consider the opinion and past experience of real money online casino players. We research the web and look for comments and reviews by experts, too. The truth is a point of view, and it's always better to check several.

Payout Potential

Not all high RTP slots come with massive jackpots and tempting maximum wins. Some are restricted by the developing studios and can't be really generous even in the long run. Therefore, we rank higher online slots with high max win caps and satisfactory rewards in the Paytable.

Fairness And Certification

As we already mentioned, the legit software suppliers are verified by third-party auditors. Their seals can be found in the footers' of the top casino sites, too. The best RTP slots in the UK have been checked and approved by test laboratories, like GLI, iTech Labs, and eCogra. They run tests of millions of spins to determine the actual RTPs.

Special Features And Innovations

Last but not least, we believe that each highest RTP slot must offer bonus features or innovative elements. They can be special mechanics, free spins, reel modifiers, or bonus symbols. The combination of all that can be both entertaining and lucrative and is what most players are looking for generally.

High RTP And Volatility

The connection between payout rates and volatility levels is truly a major factor, so we'll give it some more attention. Even the high RTP online slots can be quite risky because of their unstable volatility. As we already mentioned, high-variance machines offer bigger but less frequent payouts.

The low-volatility machines are on the opposite end - smaller but more frequent rewards. Perhaps medium-variance games are the better option, and that's why they are often described as the most beneficial. Below, we present you 5 low and highly volatile slots with high RTPs:
