10 High RTP Slots for UK Players

It’s always a smart move to know which real-money slots offer a little extra potential when you take a chance on the reels. So, we’ve shone a spotlight on some of the best RTP slots in the UK from our collection, beaming them straight from Mayfair to your fingertips.

Read on to find out some of our best online slots for real money prizes to play, plus a breakdown on why RTP matters if you’re looking for the best slots odds.

10 of Our Best RTP Slots in the UK Today

Across our collection of online slots, you’ll generally find an RTP range from the 80% to the high 90s - something we cover in more detail on our How to Win at Slots page [insert link when article published]. You can consider any game in the low-to-high 90s to be one of the high RTP slots UK players can spin with for higher odds of winning.

However, RTP isn’t the only thing that makes a slot worth your time. In fact, you’re unlikely to feel the difference between a 96% and 93% RTP slot in the short term, due to how many people play these games online.

So, we’ve narrowed the selection down to the best RTP slots in the UK. We rank them by their RTP, but each also scores high marks for themes, bonus features, and pure entertainment value.

From our grand offering of real-money slots, these are games where play meets potential.

1. MONOPOLY On The Money

Released in 2017, MONOPOLY on the Money is a classic in the fast-moving world of real-money slots online. The Light & Wonder-produced slot game features mighty multipliers and a Free Slot Spins Bonus that set the standard for all MONOPOLY mobile slots to follow.

Unlock the free spins mode and you’ll get a shot at the multipliers, which can boost your winnings. That’s not all that’s on the board here, though! There’s also the Big Bet feature, which can land respins, Community Chest Card features, and even reel-expanding House and Hotel Extensions.

With an RTP range of 94-97%, this is a slot with as much potential for payouts as fun.

2. Money Cart 2

Famously one of the outright highest of the high RTP slots in the UK at 98%, Relax Gaming’s Money Cart 2 rolls into town sporting much more than just a lofty payout percentage. The aim of this Old West, high-volatility slot is to trigger the re-spins feature.

Land three or more Bonus symbols in this 2021 slot release, and they’ll hold in place. Then, it’s over to you to fill the reels with winning symbols, unlock extra reels, and keep retriggering the respins for the chance to reach the 5,000x top prize.

3. Bad Bass Cash Towers

If you thought single-reel slot games meant fewer chances of winning, usually you’d be right. In this slot, though, the RTP stays high at 97% - giving it a reputation for paying out more to players over time.

Released in 2025 by Indigo Magic, Bad Bass Cash Towers brings high volatility and high RTP spins to the niche section of single-reel online slots.

In this game, you’re looking to climb the ladder of blue, red, or green symbols to collect payouts and reach the jackpot. The Reset Jackpot symbol acts as the booby trap, but helping you along the way is the Wild Bad Bass for chances to substitute and contribute to wins.

4. Golden Gals Cash Towers

Another of the high RTP slots in the UK from Indigo Magic, Golden Gals Cash Towers brings the volatility down to medium-high while keeping the single-reel format and an RTP hovering around 97%.

The farm-themed 2024 real-money slot has you chasing the Hen Wild to move up the towers or successive runs of Bell, Horseshoe, or Egg symbols. Find the wily fox, though, and the big Cashpot at the top will reset.

5. Rainbow Riches Leprechaun’s Gold

Light & Wonder earns another entry on this list of the best online slots for real money with high RTPs at MONOPOLY Casino. Rainbow Riches Leprechaun’s Gold launched in 2019 to build on the classic formula that powered up the series and claims an impressive RTP of 94-96%.

This Rainbow Riches slot features 50 paylines, a top payout of 1,085x, and a revamp to the triple-feature formula. Watch for the Question Mark Bonus to flip all symbols to the same for a decent payout, or the Wild Rover Bonus to add wilds to your reels. There’s also up to 25 free spins to be landed all at once.

6. MONOPOLY Utility Trails

Whether you love them or try your best to avoid them, the Utility properties of the iconic board game take centre stage in MONOPOLY Utility Trails. Created by Light and Wonder in 2021, it’s one of the top high RTP slots in the UK at 96%.

Hit Clusters of symbols to unlock the Water Works Bonus and spin the reels until at least one winning cluster lands and sticks to the reels to help further wins. Trigger the Electric Company Bonus, and your 8x7 grid fills with Chance and Property cards. Your aim? Collect the biggest possible multiplier for your chance to be Mr Moneybags.

7. Deal or No Deal: The Perfect Play

This medium-volatility addition to the Deal or No Deal online casino range brings the unique both-ways payline mechanic to the table. Released by Blueprint in 2018, this slot features five both-ways lines, which you can use to your advantage by starting your winning lines from either direction!

Deal or No Deal: The Perfect Play works very similarly to the classic fruit machine, renewed for online and mobile slots gaming. You’ll want to collect eight numbers on the reels to advance to the Super Board, which holds the big prizes. With an RTP of 96%, big prizes may not be far off.

8. Donuts

Also one of our top penny slots – with bet sizes available from 1p per line – 2022's Donuts weighs in as one of the best RTP slots in the UK at 96%. You’ve got Wild symbols on the middle reels to help make wins, but the goal in this Relax Gaming hit is to find the Scatter symbols.

Gold Donut Scatters reward you with up to 20 free slot spins. See what multiplier you’ll get from the Bonus round and then spin away with a chance to retrigger more free spins as you go!

9. Wild Link Cleopatra

Joining Wild Link Zeus to further power up this 2022 SpinPlay Games real-money slots series, Wild Link Cleopatra takes you back to Ancient Egypt to spin on a high RTP slot for a top prize of over 4,800x.

You get 243 paylines in this medium-volatility game and an overall RTP rate of 94%. The key is to land cash prizes on the reels with the Wild or Sun symbol on the first reel to unleash the titular cash-collect Wild Link feature.

10. 10,001 Nights

Step into a world of woven tales and hidden treasures with Red Tiger’s 10,001 Nights slot. This 5-reel, 20-payline real-money slot whisks you away to a gilded palace where the goal is to fill the four Feature Lamps above the reels.

Land Oil Lamps to wake the genie and unlock Imperial Spins, Random Wilds, Multi-Pick, or Mega Wilds each adding a touch of magic to your potential wins. With a top prize of over 10,000x your stake and an RTP of 93%, this is a stylish spin on a tale where every play could reveal a new fortune. It’s no wonder it’s a classic casino slot.

What Does RTP Mean in Slots?

RTP, or ‘return to player,’ shows the percentage of the total bets put into a real-money slot over time that is paid back out. So, if £10 is bet into a 95.2% RTP slot, theoretically 96.2% is the percentage gamblers win, or £9.52.

Of course, the fun of the game is that this amount is paid out unevenly, creating moments of excitement and potentially big winners along the way. You can consider the RTP to be the slot’s odds. We delve into more detail about this on our Understanding Slot Machine Odds page.

Does a High RTP Guarantee a Win?

While playing high RTP slots in the UK makes for a fun game night, high RTP doesn’t guarantee a win. The Random Number Generators (RNG) that underpin the slots make sure that every result is completely randomised, so no spin can be predicted, which adds to the fun! If you find yourself playing beyond your means, please turn to our responsible gambling tools.
