Beginner’s Guide to Top Payout Casinos by Category

The best payout casinos are adept at different things. For example, some have the best RTP slots in the UK, while others have better odds for table games or faster withdrawal processing. The best choices will be grouped by what is most important to your style of play.

We put the best payout casinos into groups based on the type of games they offer, how well they verify RTP, and how quickly they process withdrawals. If you like slots, you should look for casinos that have slots with 98% and 99% RTP. Seek out websites that offer the greatest odds for roulette and blackjack in the UK if you enjoy playing table games.

Highest RTP Slots UK

The highest RTP slots in the UK give the best long-term returns, with some games paying back 98–99% of all bets. NetEnt and Microgaming are the main companies that make these high rtp slots, but Pragmatic Play and Play’n GO also have some great ones.

Top 10 Highest RTP Slots:

Our Recommendation: Mega Joker RTP at 99% offers the best theoretical return, but blood suckers RTP at 98% provides more engaging gameplay with bonus features. If you wager £1,000 on Mega Joker, you’ll theoretically get £990 back over time, compared to £980 on Blood Suckers.

Best Payout Roulette Games

The best payout roulette games are very different depending on the version you choose. American roulette has a lower RTP of 94.74% because of the double zero, while European roulette has a higher RTP of 97.3%. If you want to get the most out of your money, stay away from American versions altogether.

The best odds roulette UK games use French rules and La Partage, which gives you back half of your even-money bet if the ball lands on zero. If you bet £100 on red and zero hits, you’ll get £50 back instead of losing the whole thing. This one rule raises RTP from 97.3% to 98.65%.

Best Payout Blackjack Games

If you use basic strategy correctly, the best payout blackjack games can have an RTP of 99.5% or higher. The best odds for blackjack in the UK can be found at casinos that offer single-deck games with rules that are good for the player, such as the dealer standing on soft 17 and blackjack pays 3:2.

Our Recommendation: Learn basic strategy before playing—it’s the difference between 99.5% RTP and 95% RTP. If you bet £1,000 with perfect basic strategy, you’ll lose approximately £5. Without a strategy, you’ll lose £50 or more on the same wagers.

How to Find the Best Payout Casinos?

To find the best paying online casinos, you need to check claims with sources that are not connected to the casinos. You should look at ecogra-certified casino reports, monthly payout reports, and test how quickly you can withdraw money.

We suggest a three-step verification process: check for eCOGRA certification, look at the published payout percentages, and try making small withdrawals before making big deposits. If a casino doesn’t make its payout reports clear, that’s a bad sign.

Understanding RTP Percentages

The casino payout percentage shows how much you could theoretically win back over millions of spins or hands. RTP gets displayed as a percentage. So, if a game has a 96% RTP, it means that for every £100 wagered, the game pays back £96 over its lifetime. But that doesn’t mean you’ll get £96 back from your £100 session. This percentage is calculated over huge numbers of plays across all players, over a long period of time.

RTP Calculation Examples:

RTP applies over millions of spins. In a single session, you might win £500 on a £100 deposit or lose your entire bankroll. Verified payout percentages show long-term averages, not short-term guarantees.

Checking eCOGRA Certification

eCOGRA-certified casinos undergo monthly audits of their game RTPs and payout processing. The eCOGRA seal is at the bottom of the casino page and links to reports that show the current certification and payout percentage.

Check the eCOGRA Verification List:

• Look for the eCOGRA seal
• Click the seal
• Check the certification date
• Review the payout reports
• Verify the name of the casino

Things to Watch Out For: If the eCOGRA seal doesn’t take you to their official website, the certification is probably fake. Always verify ecogra.org directly instead of believing what you read on the site.

RTP vs House Edge: What’s the Difference?

Highest return to player percentages and lowest house edge casino claims describe the same concept from different perspectives. You’ll understand casino odds better when you know how these two metrics relate.

RTP and house edge always add up to 100%. If a game has 97% RTP, the house edge is 3%. If you see best odds online casino advertising 1% house edge, that means 99% RTP, excellent odds for players.

RTP vs House Edge Comparison

Our Recommendation: Focus on games with house edge below 3% (RTP above 97%) for the best long-term value. The difference between 96% and 99% RTP is £3 per £100 wagered, significant over thousands of spins.

What are the Best Payout Casino Games in the UK?

What games you play will determine which ones pay out the most, but table games usually have better odds than slots. Blackjack, baccarat, and some types of video poker tend to pay out the most.

We’ve played hundreds of games on different casino sites, from slots to table games to live dealer tables, to find out which ones really pay off the most.

Slots with Best Payouts

• Mega Joker (NetEnt): 99% RTP, low volatility, £0.10-£10 stakes
• Jackpot 6000 (NetEnt): 98% RTP, low volatility, £0.10-£2 stakes
• Jokerizer (Yggdrasil): 98% RTP, low volatility, £0.10-£20 stakes

• Gonzo’s Quest Megaways (NetEnt): 96% RTP, medium volatility, avalanche feature
• Extra Chilli Megaways (Big Time Gaming): 96.82% RTP, high volatility, feature buy

Our Recommendation: Blood Suckers and Mega Joker are two of the best paying NetEnt slots with the highest verified RTPs. Best paying pragmatic slots like The Dog House Megaways (96.51%) and best paying Microgaming slots like Immortal Romance (96.86%) also give you great returns.

Table Games with Best Odds

Casinos with best odds on table games offer single-deck blackjack, French roulette, and baccarat with low commission rates. You’ll maximise returns by choosing the right variants and using an optimal strategy.

Table Game RTP Rankings:

Best odds online casino platforms offer all these variants. You’ll find best odds blackjack UK at live dealer blackjack sites and best odds roulette UK at live roulette casinos.

Progressive Jackpots That Pay Out

Best paying progressive jackpots offer life-changing wins, but you need to verify the casino actually pays large amounts quickly. We’ve identified casinos that pay out big wins without delays or withdrawal caps.

Mega Moolah Network (Microgaming):

• Average RTP: 88-92% (lower due to jackpot contribution)
• Seed Amount: £1,000,000
• Record Win: £13,213,838.68 (verified 2015)
• Payout Speed: 1-3 days for jackpot wins
• Where to Play: Microgaming casinos

Playtech Jackpot Network:

• Average RTP: 90-94%
• Seed Amount: £100,000-£500,000
• Record Win: £5,888,346 (verified 2012)
• Payout Speed: 2-5 days for jackpot wins
• Where to Play: Playtech casinos

Our Recommendation: Try to play progressive jackpots only on sites that pay out quickly and have proof of actually paying jackpot winners. We recommend checking reviews for confirmed large payouts before you start playing jackpots. Yet, if you choose a site from our list, this should automatically be a UGKC-approved one. So, it shouldn’t have any kind of issues.

How eCOGRA Rates Casino Payouts

eCOGRA certified casinos undergo rigorous monthly testing of game RTPs, random number generators, and payout processing. You’ll find these audits provide the most reliable payout percentage verification available to UK players.

eCOGRA Testing Process

• They test every game to make sure that the real RTP is the same as what it says it is.
• To get good data, they play each title at least 10,000 times.
• Variance analysis looks for strange patterns or signs of manipulation.
• You can see the results every month on casino websites.
• To keep their certification, casinos must have a full audit every year.

What eCOGRA Verifies

• Game fairness through RNG testing
• Advertised RTP accuracy for all games
• Payout processing times
• Player fund protection
• Responsible gaming tools and limits

Red flag: If a casino claims eCOGRA certification but doesn’t publish monthly reports, the certification may be expired or fake. So, always verify on ecogra.org directly.

Casino Payout Percentages Explained

The casino payout percentage shows how much money players get back from all of their games. You can see the overall RTP for the casino, which is usually between 95% and 97%. You can also see the RTP for each game, which can be very different. For example, some progressive slots have an RTP of around 88%, while blackjack has an RTP of 99% or higher.

Overall Casino RTP: This is the average of all games, with more weight given to games that players play more often. A casino with a 96.5% overall RTP means that 96.5% of all bets made by all players on all games are returned as winnings.

Individual Game RTP: Each game has its own RTP, clearly displayed in the game rules or paytable. Highest payout casino games show RTPs above 98%.

RTP Impact on Your Bankroll

Our Recommendation: Choose games with 97%+ RTP for the best long-term value. The 3% difference between 94% and 97% RTP costs you £30 per £1,000 wagered.

Best Payment Methods for Casino Payouts

Depending on how you pay, fast paying casinos handle withdrawals in different ways. When you use an e-wallet, you’ll get your money the fastest. When you use a bank transfer, it can take 3 to 5 business days.

We’ve checked the withdrawal speeds at dozens of the best payout online casinos in the UK to find out which payment methods let you get your money the fastest.

Fastest Payout Methods

Our Recommendation: Use e-wallets for fastest payout casinos experience. If you win £500 on Monday, you’ll have funds in your PayPal account by Tuesday with fastest withdrawal casinos.

Casinos with No Withdrawal Caps

You can take out as many funds as you want from casinos that don’t have withdrawal limits.  This means you don’t have to break up big wins into smaller payments. If you win a progressive jackpot or more than £10,000, you’ll need to use an unlimited withdrawal casino.

What We Think: Before making a large deposit, make sure you know the withdrawal limits.  A lot of Playtech sites and Microgaming casinos pay out jackpots quickly and without limits.

Are There Casinos That Pay Out Larger Sums?

Casinos that pay out higher sums have proven track records of processing £10k+ withdrawals quickly and without disputes. You’ll want payout proof before trusting a casino with large deposits or chasing progressive jackpots.

We’ve documented actual examples of casino payout records from UK players who received large withdrawals:

Verified £10k+ Payouts:

• £13.2 Million Mega Moolah Win (Microgaming casino, 2015)

How We Test & Review the Best Payout Casinos?

Our team puts the UK online casinos through a strict testing process to find the ones with the best payout rates. We make real deposits, test withdrawals, and check eCOGRA reports to make sure that our suggestions will give you the returns we promised.

RTP Verification Process

Before we recommend a casino, we double-check that its payout percentages are genuine and reliable. We begin by confirming on ecogra.org that the site’s eCOGRA certification is still valid. After that, we go through the casino’s payout reports from the previous three to six months to see whether the numbers look consistent. Lastly, we check to see if the RTP they post publicly matches the data they actually report. If something doesn’t seem right, we contact the casino for more information and keep looking into it ourselves.

Withdrawal Speed Testing

To see how fast a casino really pays out, we run real withdrawal tests using multiple payment methods. We usually deposit £50–£100 via options like debit cards and e-wallets, play until we reach around £100-£200, and then request withdrawals with each method. We record exactly how long it takes for the money to reach our accounts. To keep things fair and consistent, we repeat this process two or three times at every casino we review.

Large Sums Payout Verification

We take a close look at how casinos handle larger payouts by checking real examples of players cashing out £10,000+ and browsing forums to see what other players’ experiences have been like. We also test it ourselves by asking for bigger withdrawals to see how well it works. Finally, we read the casino’s rules to make sure there aren’t any hidden rules or limits in the fine print.
