Best payout online casinos in the UK

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) details the percentage of funds that will be returned to customers playing casino games online.

Naturally, playing at high RTP online casinos gives customers a better chance of winning.

We’ve provided a rundown of the best payout online 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 best 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.

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.

Casino sites 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.

In addition, 10Bet clearly advertises the RTP of a specific live casino or slot game, particularly on their offers page, in contrast to some online casinos, who make it more difficult to find out that information. 

Highest paying online casino for blackjack: Grosvenor 

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 achieve that RTP. 

You are unlikely to go wrong wherever you play blackjack, but we found Grosvenor Casino to be the highest paying blackjack casino.

Grosvenor has a number of different types of blackjack, both in their online casino and live casino.

In the online casino, you can play traditional blackjack, blackjack surrender and multi-hand blackjack. Blackjack in the live casino can vary in RTP, but not massively, ranging from between 99.28 per cent and 99.50 per cent.

The blackjack game with the highest RTP on Grosvenor is European blackjack at 99.60 per cent.

Among Grosvenor’s many promotions, bettors will find a blackjack-specific offer. Just stake £5 or more on selected blackjack games, and if a lucky card appears, users could win a cash prize or a free bet for the sportsbook, both worth up to £25.

Best payout online casino for roulette: Betway

Betway is among the best high RTP roulette casinos, and it offers all types of roulette, with 56 different versions of the game to be found across their online and live casinos. Roulette is their most popular dealer game on their casino product.

Roulette tends to have a lower RTP than many traditional casino games due to the increased possibility of bettors’ losing.

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.

Betway’s 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.

What is game volatility in online slots?

Game volatility differs from RTP as it refers to the level of risk involved in terms of the size and frequency of pay outs.

The volatility, or variance as it is sometimes referred to, allows different types of players to choose games that suit their budget and intentions.

A low volatility game should provide frequent wins of a small nature – these are aimed at players who enjoy steady gameplay with a small amount of risk.

High volatility games, on the other hand, are aimed at players who want a high payout, though they must accept that returns are few and far between.

It is a more risky approach but it appeals to some casino players as payouts on high volatility games are higher than low volatility online slots.
