10 Best Paying Slot Games
Wondering how to pick a winning slot machine? Slot machines are completely random, but the guaranteed way to increase payouts is to check the slot's Return to Player percentage. The higher the RTP, the better the chances of cashing in on your wins.
Here are 10 slots with the highest RTP to play:
Slot game
RTP
Mega Joker by NetEnt
99%
Blood Suckers by NetEnt
98%
Ugga Bugga by Playtech
99.07%
1429 Uncharted Seas by Thunderkick
98.6%
White Rabbit Megaways by Big Time Gaming
97.72%
Jackpot 6000 by NetEnt
98.86%

99% in Big Bet Mode
Devil’s Delight by NetEnt
97.6%
Starmania by NextGen Gaming
97.87%
Book of 99 by Relax Gaming
99%
It's unlikely that your payout will exactly match the indicated percentage. However, you have a better chance of winning more on a game with a 95% RTP than one with a 90% RTP.

What Is a Casino Payout Percentage?
A game’s RTP is a percentage that indicates the amount of money you can expect to be returned to you from your bets. A slot game’s average RTP is calculated through software simulations over 100,000 betting rounds.
☝️ Example: If a slot has an RTP of 95%, the player can expect an average of £95 back in winnings for every £100 they wagered.
According to the UK Gambling Commission, there is no minimum RTP requirement for slot machines, and the chances of winning remain consistent, not influenced by previous wins or losses. Every slot machine in the UK must clearly display its RTP rate to slot players.
Institutions That Publicly Disclose Casino Payout Percentages
In the UK, several institutions and organisations are involved in the oversight and regulation of online gambling, including the disclosure of casino payout percentages for an optimal casino experience.
Here are other key organisations:

Learn How to Find the Best Payout Casino in the UK
Follow our expert-approved tips below to find the best and highest paying online casino in the UK:
Check Our Casino Reviews
Look at the casino reviews at Mr. Gamble to get a good idea of casino payout rates and find the top paying online casino. With several years of combined experience in the industry, our team knows exactly what to watch out for when evaluating the best casino payout 2025 sites. They are looking for fair payout online casinos, low house edge, fast payouts, and slot machines that are most likely to hit.
Check Return to Player (RTP)
You need to check the RTP of any games you are interested in playing, so you know what your potential long-term returns might be. Just click the help or info button within the game. This will open up a screen showing key details: the payouts, the RTP, and the number of paylines. Check all these factors to pick the best paying online slots.
Volatility has an impact on your gaming session and this factor goes hand-in-hand with the RTP.
Check the House Edge
A house edge is also known as a casino’s statistical advantage any time you play a slot or any other casino game. A game with a high house edge will pay out less on average.
☝️ Example: If you bet £100 on American Roulette with a house edge of 5.26%, the casino can make a £5.26 profit on your bet.
While a game's house edge is designed to ensure that the casino wins in the long run, it doesn’t mean that Lady Luck can’t come your way to gift you a life-changing win. Pay attention to the specific rules, payout structures, and odds of each game to find the best payout online casino real money games.
Check Withdrawal Fees
Most online casinos with quick payouts have a dedicated Payments page which displays the minimum and maximum deposit and withdrawal limits. If this page is not available, head to the ‘Terms and Conditions’ page, where you will find listed any withdrawal fees, casino payout times as well as maximum limits per day, week, and month.
Top 7 Tips on How You Can Win Real Money at UK Casinos
Here are the best advice for slot players who wish to increase their chances of winning.
Look for the Best Payout Percentages
No matter how fun casino games may be, if they have a poor RTP (85% and less), they hardly qualify for casinos with the highest payout rates. For example, casinos with blackjack tend to have higher RTP rates based on the game variations available.
Seek Out Realistic Wagering Requirements
Wagering requirements are the amount you need to wager to withdraw any winnings from a bonus. Avoid higher wagering requirements (50x or higher). Welcome bonus offers and promotions for existing players may have different playthrough requirements.
Only Play at Casinos With an Excellent Reputation
Do your due diligence before signing up even at the best paying gambling sites. Ensure they have a solid reputation and no history of issues.
Use Fast Withdrawal Payment Methods
Withdrawal times are as important as a good payout rate for online casino games. If you are playing a progressive jackpot in the United Kingdom and hit the jackpot, you will want the quickest payout available. Top fast withdrawal methods include e-wallets like PayPal, Neteller, and Skrill, which are known for fast processing.
Make Sure the Games Are by Top Gaming Providers
The best gaming providers like NetEnt and Microgaming to name a few, go through a lot of testing and regulation to ensure they offer fair and high-quality and high slots payouts.
Use Casino Bonuses
Use casino bonuses as part of your strategy to boost your bankroll and extend your gaming session. Casinos with the highest RTP are likely to offer various promotions, such as welcome offers, free spins and free bonus offers.
Check the data within the terms and conditions to verify the wagering requirements, eligibility of games and expiration dates, so you can convert your bonus funds into withdrawable cash even from a no deposit bonus.
Practise Responsible Gambling
Even if you opt for the best payout rate for online casinos, practice responsible gambling. Set time and spending limits before you start playing, despite the different payout rates available for games.
You may pick a top online casino based on its overall payout rate, but keep in mind that casinos still have a high house edge. Manage your bankroll properly and take regular breaks.
Payment Methods at the Top UK Casinos for Payouts
When choosing a high-paying casino, consider the payment methods available, the withdrawal process and limits, and any fees associated with deposits.
If you’re looking for a casino that offers fast payment processing and transparent fees and policies, here’s a quick rundown:

Frequently Asked Questions
What is RTP in online casinos?
RTP (Return to Player) is the theoretical percentage of all wagered money a game is designed to pay back to players over time. For example, a 96% RTP suggests that, on average, you would get back £96 for every £100 wagered.
What online casino pays out the most?
Online casinos that pay out the most typically feature a wide variety of high-RTP games, with average payout rates of 97% and higher, meaning players can expect to receive back 97% of their wagers over time. Along with great odds, these casinos also offer smooth and quick withdrawal processes, making it easy for players to access their winnings without unnecessary delays.
Which casino games offer the best payout rates?
Casino games like blackjack, video poker, and roulette typically have the highest payout rates due to their lower house edge. For example, blackjack can have an RTP as high as 99% when played with optimal strategy, while certain roulette versions, like European roulette, offer better odds compared to American roulette. Always check individual game RTPs for precise information.
Which online casinos are known for the biggest wins?
Online casinos with progressive jackpot games like Mega Moolah or Wheel of Wishes by Microgaming are famous for producing life-changing wins, often offering jackpots that grow into millions of pounds.
Licensed platforms offering progressive jackpot slots are your best bet for consistent winnings.
What is considered a good payout rate at online casinos?
A good payout rate, or RTP, at online casinos is generally 96% or higher. This means that for every £100 wagered, an average of £96 is returned to players as winnings.
