Getting the best value for money is vital for players signing up for and using online casinos.
High payout rates (known as RTP, or return to player) detail the percentage of funds that will be returned to customers playing casino games online.

We want to provide readers with an accurate and up-to-date guide on different categories of casino, so we’ve provided a rundown of the best high payout casinos in the UK across various game types, helping players to make an informed decision before choosing their preferred casino.

**What is RTP (Return To Player)? **
Before we look at the highest payout casinos, it’s important to know what RTP is. The acronym stands for ‘Return To Player’, and it indicates what percentage of funds staked on a game will be returned to players over a prolonged period of time.
It is important that punters are not misled by the RTP on a game. For example, if a slot game has an RTP of 97 per cent , it doesn’t mean you’ll get £97 back if you gamble £100 - far from it. Instead, your losses contribute to the overall RTP of the game, and someone will be paid out sooner or later.
For more information on the concept, read our guide to RTP.
An online slot game with a 97 per cent RTP means the game will return £97 for every £100 wagered by all players, but the percentage is calculated over millions of spins. Therefore, RTP cannot be used to estimate your own winnings when setting out a budget.
Casinos that payout are required to stick to the RTPs set by online game providers, and governing bodies such as the UK Gambling Commission (UKGC) and eCommerce Online Gaming Regulation and Assurance (eCOGRA) ensure regulated operators adhere to the percentages.
Highest payout casinos UK: Mega Riches
Rating: ⭐⭐⭐⭐⭐
Average RTP: 98.97%
Mega Riches earns its reputation as one of the best casinos that pays out in the UK thanks to a standout RTP approaching 99%. What sets it apart is the WinBooster rewards system – a cashback-based loyalty feature that delivers real, withdrawable cash every week.
Rather than relying on traditional free spins or high-wagering bonuses, Mega Riches takes a transparent approach: your cashback is calculated based on your total wagering activity and the RTP of the games you’ve played, whether that’s slots, jackpot slots or live dealer tables.
It’s a refreshingly simple and fair model, especially for a relatively new casino, and one of the most rewarding loyalty programmes we’ve come across. You can easily track your cashback progress via your account dashboard, and unlike many other operators, there’s no confusing point conversion or hidden restrictions.
If you’re tired of bonuses tied to excessive wagering terms, Mega Riches provides a clear route to genuine cash rewards, establishing itself as one of the top casinos for high payouts in our verdict.

Best payout casino for roulette: Betway
Rating: ⭐⭐⭐⭐⭐
Average RTP: 97.30%
Betway is among the best high RTP roulette casinos, and it offers all types of roulette, with 70 different versions of the game to be found across their site. Roulette is their most popular dealer game on their casino product.
Roulette sites often feature games with lower RTPs compared to some casino games like blackjack, primarily due to the house edge inherent in roulette’s design, especially in variations like American roulette.
Most roulette games have an RTP ranging from 94.74 per cent to 97.30 per cent, although you can play French roulette on Betway which has an RTP of 98.65 per cent when played using La Partage rules.
The Betway sign up offer rewards new users with 100 free spins. Once you’ve completed the welcome bonus, fans of roulette can enjoy the Lucky Numbers promotion to win up to £50 in bonus funds if a bettor’s chosen lucky number comes up.
On the negative side, this bonus only really caters to slot players, while withdrawals can take longer than some of our other recommended brands.

**Highest paying casino for blackjack: Grosvenor **
Rating: ⭐⭐⭐⭐
Average RTP: 97%
On average, blackjack has the highest RTP of any traditional casino game, reaching over 99 per cent in most cases, although it does require skill and strategy to win.
When researching the best blackjack sites, we found Grosvenor to be the highest paying blackjack site.
Grosvenor has a number of different types of blackjack. It stands out as a top choice for blackjack players thanks to its consistently high RTP across both digital and live tables.
They offer classic blackjack, multi-hand variants and blackjack surrender, while the live casino delivers RTPs between 99.28% and 99.50%.
The best value comes from European Blackjack, which boasts an impressive 99.60% RTP, one of the highest available at any major UK operator.
Grosvenor also runs a dedicated blackjack promotion: stake £5 or more on selected tables and, if a Lucky Card drops, you can win a cash reward or free sports bet worth up to £25.
The only drawbacks are slightly slower withdrawal processing times and a smaller range of payment methods compared with a few competitors, but for pure blackjack value, Grosvenor remains the best choice.

How we rank and review the best high payout casinos
Whether we’re testing a new UK casino or an established brand, we use a set of stringent criteria to rank and review the best payout casinos. These are discussed below.
- Licensing -All of the casinos that we recommend must be licensed and regulated by the UK Gambling Commission. This ensures that they operate legally and fairly – this licence is non-negotiable.
- Security measures -In addition to licensing, the best payout casinos will use up-to-date security measures such as SSL encryption and two-factor authentication. These help to keep player data and details secure.
- RTP and payout rates -The best payout casinos will be transparent with their RTP percentages, while offering several games with a range of RTP rates.
- Game variety -The best payout casinos will have a great selection of games in multiple forms, from new slots to table games and live dealer offerings. We have checked the number and variety of titles, as well as checking how often they update their library with new and exclusive titles.
- Banking options -The most trusted casinos offer a range of secure payment methods for deposits and withdrawals, including debit cards, bank transfer, PayPal casino and e-wallets. A pay by mobile casino can also be considered as they allow users to transfer credit from their phone to their casino account. Generally, a fast withdrawal casino provides modern methods of banking - the more options, the better.
- Promotions -The highest paying casinos should offer top sign up offers, as well as plenty of promotions for existing customers, from free spins and betting offers to jackpots.
- User experience -One of the most important things to consider when recommending a high RTP casino is the overall user experience. Casino sign up offers, existing promotions and a variety of games all contribute to this, as does the functionality of the desktop sites and casino apps.
- Customer service -The best RTP casinos offer a range of customer service tools including live chat, email and phone options. Ideally, these will be accessible 24/7 too.
- Responsible gambling- It’s absolutely essential for the casinos we review to take responsible gambling seriously and we take note of prominent messaging across sites and apps, and mark brands down when visibility is low.

Responsible gambling is extremely important when playing on a high paying casino online. Never be tempted to chase any losses, and the same applies if you’re playing on betting apps, bingo sites, poker sites or any other type of gambling medium.
