How Do I Check an Online Casino’s RTP?

If you're looking for the best payout online slots, you should check the RTP percentages for each game you play. RTP can vary between casinos, so it's important to examine the RTP percentages at each casino where you play.

Which casino games typically offer the best payouts?

Online blackjack is often thought of as the casino game with the best payout percentage. Its house edge is around 1% or lower if you use basic strategy . With sharp skills, you can win frequently on blackjack, even if it doesn't pay the most, though remember that the odds are still in the casino's favour. If you're looking for better returns from slots, your best bet are slots with an average RTP of over 97%.

What is a good slot payout?

The current RTP industry average for highly volatile slots is 96%. You should always aim for that figure or higher over 97%. Check out the slots we recommended above and you'll find a top-paying slot machine in return for your bets.

Which online slot has the best payout casinos rate?

With new slots coming out on a regular basis, the slot with the highest payout rate may change from time to time. Currently, we recommend Ugga Bugga by Playtech, Mega Joker by NetEnt, and Book of 99 by Relax Gaming. Each of these slots has an RTP of 99% or over.

Does Claiming a Bonus Offer Affect Casino Payout Rates?

While claiming a bonus doesn't alter a game's inherent RTP, bonus terms, such as wagering requirements, can impact the amount of your winnings you can ultimately withdraw. A casino bonus with lower wagering requirements will give you one of the best casino payouts compared to casinos with high wagering. It's crucial to carefully review the bonus terms and conditions to understand any restrictions before accepting an offer.

Best Payout Online Casino UK (2025)

For better or for worse, certain casinos simply pay out better than others. We understand how important getting the best value for money is when it comes to your casino experience. That’s why we’ve compiled a list of the top-paying casinos in the UK, featuring the highest RTP slot games generous bonuses, a fast payout speed and zero transaction fees to ensure you get the most out of every spin and wager.

What Does The Best Payout Mean At Online Casinos in the UK?

Simply put, the best payout online casinos refer to the sites where you get the best value for your money. While the saying “the house always wins” remains true, some casinos tend to offer better returns; these are known as high-payout casinos.

A high-payout casino is one which offers a higher win rate compared to the average casino. This can be due to several factors, including welcome offers and bonuses, high RTP games, as well as no fees for deposits or withdrawals.

Understanding RTP (Return to Player)

When online gambling Return to Player, or RTP, is a crucial factor in determining a casino game’s likely payout. The higher a slot’s RTP, the more it is likely to return, making it an important variable in online casino payouts. Hypothetically, if a slot has an RTP of 96%, for every £100 staked, it is likely to return £96, which is obviously, more than that of slot games with 94% or 92%. While this might seem like a cheat code to maximising your win potential on the best online slots, several key factors influence how RTP is calculated:

Number of spins

The RTP is calculated over millions of spins by Random Number Generators (RNGs). This means that even with a higher RTP, a slot remains unpredictable and exciting.

Maximum wins

RTP also accounts for big wins and the maximum win potential. A high RTP doesn’t guarantee frequent payouts, just as a low RTP doesn’t necessarily mean fewer frequent wins.

Volatility

Many players confuse volatility and RTP. While often connected, they have distinct meanings. Volatility controls the frequency and size of wins. High-volatility slots tend to pay out larger but infrequent wins, while low-volatility slots pay out smaller wins more frequently.

RTP Variation

A game’s RTP can vary between many online casinos, as some slots are made with interchangeable RTP variants. However, we’ve researched the highest-paying casinos and compiled a list of recommended sites with the highest RTP variants to help maximise your wins.

How to Calculate Payout Percentages

In UK online casinos, the payout percentage, also known as Return to Player (RTP), represents the amount a casino pays out relative to the total amount players wager. It’s an average calculated over a vast number of games or spins, not a guarantee of individual returns.

Casinos in the UK are required to publish RTP information, ensuring transparency for players. To determine the payout percentage, you simply refer to the stated RTP for a game or the overall casino. For instance, a slot with a 96% RTP has a payout percentage of 96%. This means that for every £100 wagered collectively by UK players, the game is expected to return £96 in winnings. The difference between 100% and the RTP is the house edge, which represents the casino’s profit. It’s crucial to understand that these are long-term averages; short-term results in casinos can and will vary due to chance, also known as variance.

For better odds, seek casino games with higher RTPs. Look for licensed casinos under the UK Gambling Commission, which ensures fair play through regular testing by independent auditors across any British casino, these results are publicly available.
