These casinos have a high RTP rate and house edge as crucial factors influencing game payouts and the overall winning potential. Here, I’ll explain how these casinos work, how you can identify the highest payout casinos based on their game selections, and also offer some tips to maximise your winnings.

When assessing casinos, it is essential to understand the basis for comparisons and how each casino is ranked. The best payout online casinos in this guide are carefully selected because they rank highest for various categories.

What is return-to-player (RTP)

RTP is an online gaming and gambling term that refers to the winnings, prizes, or percentages that casinos return to players, depending on their initial deposits.

A high RTP casino offers at least 95% RTP and, conversely, has a lower house edge. This means the casino slots will pay out 95% of the total purchases players make over the long term, while the casino has a 5% house edge.

It is essential to understand that the RTP doesn’t mean the return you get on your gambling purchases and cannot be used to estimate your winnings. The UK Gambling Commission (UKGC) and eCommerce Online Gaming Regulation and Assurance (eCOGRA) require casino operators to stick with the RTP.

The 5 best payout casinos UK compared

What I considered for reviewing the casinos

I considered eight criteria for ranking the best payout online casinos in the UK. These criteria cover everything, from my gaming experience to banking and customer support.

1. Return-to-player (RTP) rate

The RTP rate was the filter I used to get only the casinos with a high RTP of at least 96.0%. Choosing high RTP casinos increases the payout potentials, so players can enjoy their games with the confidence that payouts are fairly operated.

I checked the BetMGM game selection and noticed that the RTP rate differs according to the game and the providers. Although most providers have a high RTP of at least 95%, the difference is negligible.

2. Payment methods and transaction speed

BetMGM casino provides a range of banking methods for smooth and flexible deposits and withdrawals. Card method allows MasterCard, Visa and Amex, and some of the casinos also accept Maestro. E-wallets are used, with PayPal, Skrill, Apple Pay and Google Pay popular options.

The top payout online casinos also offer bank transfer. I noticed that all of the casinos process deposits instantly and the funds arrive typically within a few minutes but not more than an hour under normal conditions. Withdrawals, however, take between 24-72 hours for most casinos as they have to confirm the payouts.

3. Casino licence and regulatory compliance

UK-focused casinos should be registered and licensed by the UK Gaming Commission (UKGC). Regulatory compliance ensures that casinos operate within stipulated rules, so players know their rights and responsibilities. Regulated casinos also offer only games that are tested for random number generation (RNG), which assures that games are fair and not manipulated.

Finally, it helps with playing without the worries of patronising an illegal casino or the security of funds. BetMGM is licensed by the UKGC and is currently legal in several states in the US as well. Casinos also use standard industry security protocols to secure user data and funds.

4. UX design and mobile availability

The user experience rates the ease and flexibility of navigating casinos and also the overall gaming experience, from registration to navigation, placing bets and exploring the features.

Most casinos use modern game designs with rich colours and exciting sounds. They also use a variety of themes and offer quick navigation that allows players to reach important menus from anywhere in the game. For BetMGM, I discovered it optimised the web and mobile app for a great experience on iOS and Android.

5. Promos and bonuses

Bonuses serve two functions: attracting players and providing them with an advantage. The best payout online casinos offer generous welcome packages, such as free spins, deposit match ups and additional deposit bonuses.

They may also have VIP programmes for rewarding long-term players. BetMGM provides 500 free spins + 100% deposit match up £1,000 and a £25 no deposit bonus. The bonuses do not require a code.

6. Sports/markets/games selection

BetMGM features slots, Blackjack, Roulette, Baccarat, VideoPoker, LiveGames, Craps and LiveDealer from leading providers. I found that these games are carefully selected based on the RTP, story, theme and popularity, among other criteria.

Most of the casinos also offer classic games for players who want a taste of traditional casinos. They may also offer online sportsbooks for interested players looking to bet on football, basketball, hockey, horse racing and other games.

7. Customer support

BetMGM’s customer support is available via live chat and email. Casinos typically offer phone support and may also assist players through their social media. The FAQ/Help Centre is an underrated place to find quick answers to questions. I explored BetMGM’s FAQ and was able to understand the registration process quickly.

8. Online casino ratings on AskGamblers, Casino Tops Online, Trustpilot, Casinomeister and Time2Play

I checked five of the trusted casino review platforms to find honest ratings for the best payout online casinos.

I found that most reviewers based their scores on the speed of resolving issues, the mobile experience, and the bonus packages. While the reviewers were mostly satisfied with the game offerings, the lack of mobile apps and the poor navigation of some casinos was a constant issue they addressed.
