Best Online Casinos that Payout Reviewed – Top 3 Recommendations

When looking for the best payout casinos online, it’s important to check factors like the availability of high RTP games, withdrawal speeds, bonus value, and overall trustworthiness. 

Here are the highest paying online casino sites in the UK that tick all the important boxes:

Highest Paying Online Casino Games

The primary reason the best payout casinos are called such lies in the fact that they offer the highest paying games, that is, games with the highest Return to Player (RTP) percentage.

RTP represents a long-term statistical average of player returns, calculated over millions of game rounds over a long period. Think of it as an inverse of house edge: if a game has a house edge of 2%, that means its RTP is 98%.

From classic slots and table games to new crash and fishing games, here’s a detailed breakdown of games and their average RTPs:

Editor’s Tip: If you see RTP listed as a range for some games that’s because some titles have special features like bonus rounds or multipliers. Apart from boosting your winning chances, they also serve to add a novel gameplay mechanic and freshen up an old classic. 

Slots: Up to 99% RTP

Most of the best-paying slot games in the UK have an average RTP of 96%, but a few standout titles can go much higher. 

If you’re chasing online casinos with the highest slot payouts, it’s worth focusing on those rare games that edge closer to 99%. For example, Book of 99 by Relax Gaming has one of the highest RTPs of 99%. 

The best online casinos that payout also offer features like extra paylines, respins, wild multipliers, and bonus pick rounds for better casino payout rates. NetEnt’s Mega Joker with a progressive Supermeter mode is a prime example. Once activated, it gives you access to higher-paying spins and a jackpot element.

• Common RTP range: 96% – 99%

Title	RTP	Max Win	Special Features
Book of 99 (Relax Gaming)	99%	5,000x stake	Expanding symbols, free spins
Mega Joker (NetEnt)	99%	Progressive jackpot	Supermeter mode, classic fruit slot style
777 Crystal Hall (PlayNGo)	96.20%	200x stake	expanding reels, free spins, 3x multiplier, instant prizes

Blackjack: Up to 99.8% RTP

Blackjack is one of the few games where you can push your winning potential. Most versions sit around 98–99% RTP, but the best ones go even higher. That’s why blackjack is a top choice for steady long-term value.

One of the standout titles is Vegas Single Deck Blackjack, available at all of the best online casinos in the UK. With just one deck in play, the house edge drops significantly, and the RTP can reach about 99.7% if you play with the right strategy.

Another option worth a try is Blackjack Switch. While its base RTP is at around 99.4%, the unique feature of being able to switch your top two cards between two hands gives you an extra edge.

Many online blackjack tables now also offer multihand play, letting you spread your action across three to five hands at once. Side bets, like 21+3 or Royal Pairs, can also trigger payouts as high as 100:1.

• Common RTP range: 99% – 99.6%

Title	RTP	Max Win	Special Features
Vegas Single Deck Blackjack	99.8%	1:1	Single deck, very low house edge
Blackjack Switch	99.92%	1:1 (switch wins vary)	Switch the top cards between two hands
Multi-Hand Blackjack	99.34%	1:1 per hand	Play up to 5 hands at once, faster action

Roulette: Up to 98.6% RTP

Sticking to single-zero versions is key in roulette, which gives you far better odds than the double-zero American wheel.

European Roulette is a go-to with 97.3% RTP. With only one zero on the wheel, the house edge is small, making it a great choice for reliable returns.

French Roulette takes it a step further with the La Partage rule, resulting in an RTP of around 98.65%. That’s one of the very best rates you’ll find on any table game.

• Common RTP range: 94% – 98% 

Title	RTP	Max Win	Special Features
French Roulette	98.65%	Standard table limits	La Partage rule, best RTP in roulette
European Roulette	97.3%	Standard table limits	Single zero, simple and steady returns
Lightning Roulette	Up to 97.1%	Up to 500× bet	Random multipliers on straight-up numbers

Casino Poker: Up to 99.4% RTP

Only a few poker variants at the highest paying online casino sites in the UK stand out for their high payout potential. RTPs vary, but some games can get very close to better returns with the right strategy.

Ultimate Casino Hold’em is one of them, with an RTP reaching around 99.5%. It also allows you to raise your initial bet to four times when you’ve got a strong hand.

Three Card Poker is another popular option at all online casinos, including non GamStop casinos. Its Ante/Play bets have around 96.6% RTP, but the real fun comes from the Pair Plus side bet. A straight flush can pay 40:1 here.

• Common RTP range: 95% – 99%

Title	RTP	Max Win	Special Features
Ultimate Texas Hold’em	99.47%	Varies by table	Raise up to 4x, strong strategy-based gameplay
Three Card Poker	96.63%	40:1 on side bet	Pair Plus side bet with premium payouts
Caribbean Stud Poker	Up to 97.44%	Progressive jackpot	Jackpot side bet, Royal Flush pays huge

Baccarat: Up to 98.9% RTP

This simple card game has some of the best odds. Most versions sit between 98.5% and 98.94% RTP, which makes it one of the strongest picks if you value consistency.

For example, in classic Punto Banco Baccarat, betting on the banker hand comes with an RTP of 98.94%, while the Player bet is close behind at 98.76%. That slim edge explains why high rollers often favour baccarat.

Some variants tweak the formula. Lightning Baccarat by Evolution adds random multipliers on certain cards each round. You could see your winning hand boosted by 4x, 8x, or even more. RTP is 98.5% combined with multipliers offer bigger win potential.

• Common RTP range: 98.5% – 98.94% 

Title	RTP	Max Win	Special Features
Punto Banco Baccarat	98.94% (Banker)	Standard table limits	Classic version, strong Banker bet odds
No Commission Baccarat	98.94%	Standard table limits	No 5% commission, adjusted Banker payout
Lightning Baccarat	Up to 98.68%	Up to 8× boosted wins	Random card multipliers, higher win potential

Live Dealer: Up to 99.2% RTP

Usually, live dealer tables offer the same RTPs as their RNG versions on the best payout online casinos in the UK. Live European Roulette runs at 97.3%, while Live Blackjack reaches about 99.4% with a correct strategy. 

Some tables also add side bets or twists. For example, Infinite Blackjack allows unlimited players and extras like Hot 3. 

If you want big thrills, play live game shows that come with bonus rounds, lower 94–96% RTP, and wins up to 20,000x, such as Crazy Time. It’s worth noting that even live dealer tables are optimised for casino apps and mobile play.

• Common RTP range: 95% – 99% 

Title	RTP	Max Win	Special Features
Live Blackjack	99.28%	Standard table limits	Side bets available, immersive dealer play
Infinite Blackjack	99.47%	Standard table limits	Unlimited seats, side bets (Hot 3, Bust It)
Crazy Time	96.08%	Up to 20,000×	Live game show, multiple bonus rounds, big multipliers

Provably Fair Games: Up to 99% RTP

Provably fair games are big at crypto-friendly casinos, which let you check every outcome yourself. They use cryptographic algorithms, so you know the results aren’t manipulated. 

While you won’t usually find them at UKGC sites, they’re very popular internationally for their fairness and high payout rates.

Crash games have an RTP of around 97%, like Aviator. The multiplier climbs higher, and you need to cash out before it crashes. 

Plinko is also an interesting option, where you drop a ball through pegs into prize slots. In low-risk settings, RTP can reach 98–99%, giving you steady returns. 

• Common RTP range: 97% – 99%

Title	RTP	Max Win	Special Features
Aviator (Crash)	97%	Varies by cash-out	Cash out anytime before the crash
Plinko	98–99%	Varies by slot	Risk levels, frequent small wins
Crypto Dice	98–99%	Varies by odds	Custom number ranges, very low house edge

Editor’s Tip: To comply with UK anti-money laundering laws, some UK sites cap how much you can win in a day or on a single bet, especially on high volatility games. Always check the terms first if you’re a high roller chasing big payouts.

Payment Methods at Best Paying Online Casino Sites

After you’ve won at the best payout casinos in the UK, you’ll need a fast and secure payment method that won’t drain your balance with fees and impose limits.

We recommend using crypto, which offers the highest limits, the lowest fees of all other methods, extra privacy, and sometimes bigger casino bonuses.

You can also use e-wallets, debit and credit cards, and bank transfers, but these get progressively slower and more expensive, as shown in this quick comparison table below:

Payment Method	Max Withdrawal	Withdrawal Speed	Fees
Crypto	Up to £500,000	In minutes	$0.01–$5
E-Wallets	Up to £5,000	Within a few hours	1%-2%
Credit Cards	£5,000	Within a few hours	3%-10%
Bank Transfer	£5,000	1–5 business days	0%-3%

Editor’s Tip: If you hit a big win, be mindful of your payment provider’s limits. Even the best payout casinos might ask you to withdraw in increments if the amount exceeds daily or weekly cash-out limits.

The Highest Paying Online Casino Bonuses

The highest paying online casino sites in the UK release plenty of bonuses throughout the year.

While they’re all designed to give you a boost and help you win in some capacity, they all carry different fine print that can significantly affect the payout rate.

Here are the top bonus types to watch for and how to get the most out of them:

Cashback

Cashback offers give you back a percentage of your losses, usually 5–20% weekly. The best part is that cashback often has little or no wagering rule. So, you can withdraw or play it straight away.

Since it applies to most games, it effectively boosts your returns. For regular players, it’s a safety net and one of the most valuable bonuses.

• Example: 10% Cashback every Monday

VIP Clubs

VIP clubs reward consistent play with perks that improve your long-term returns. You climb tiers by earning points that you can exchange for exclusive bonuses and personalised perks. Some VIP programs also offer cash rewards or exclusive tournaments. 

These extras effectively boost your overall payout rate by giving you back value on top of play. Certain new casino sites, also featured on this page, sometimes offer better VIP perks to attract new customers.

• Example: Climb Bronze to Platinum level to earn cashback, free spins, higher withdrawal limits, and even personal account managers.

Tournaments

Casino tournaments let you earn extra prizes on top of normal play, often through slot leaderboards. Many have free entry. So if you’re spinning anyway, you could share a thousand-pound prize pool. 

To boost returns, stick to high RTP slots and only join formats that suit your budget.

• Example: A tournament might have a £50,000 prize pool with a £2,000 share for the top winner. 

Welcome Bonus

A welcome bonus matches your first deposit, often up to a set credit value with some free spins. Wagering is 20–30x, so stick to games that count 100%, mainly slots. 

You can pair the bonus with high-RTP slots to have a better chance of clearing requirements and cashing out successfully.

• Example: 100% Welcome Bonus up to £300 + 50 spins

Crypto Bonus

A crypto bonus rewards you for depositing with Bitcoin, Ethereum, or similar coins. Offshore casinos often make these bigger than standard offers. 

Wagering is usually 40x or lower. Use this bonus on high RTP table games to have a better shot at clearing the requirements, but always check the terms as game restrictions vary for each highest paying online casino in the UK.

• Example: 150% Crypto Match Deposit up to 1 BTC

Reload Bonus

A reload bonus gives you extra funds of around 25–50% on specific days when you top up again. While smaller than welcome offers, they’re valuable for regular play since they stretch your bankroll again. 

Wagering requirements for this bonus can range from 30x to 40x. As i the case with other match-up bonuses, it’s wisest to pair reloads with high RTP blackjack or slots.

• Example: 50% Sunday Reload Bonus up to £50

Editor’s Tip: Always check bonus terms before you play. Look at the rollover, expiry dates, and game contribution rates. Slots often count 100%, while table games may only count 10% or less.

Best Payout Casino Myths – RTP Misconceptions

When it comes to high RTP games, plenty of myths float around. By clearing up these misconceptions, you’ll know what really affects your payouts and avoid the common traps that cost you money.

Myth #1: Best Payout Means Fast Payout

In reality, the best payout refers to high RTP games. Fast payout is about withdrawal speed, which depends on the casino’s banking process. A site might offer 99% RTP games but slow withdrawals, or instant cashouts on low RTP slots.

Myth #2: A Higher RTP Means More Frequent Wins

RTP is a long-term average, not a short-term guarantee. A 98% RTP slot can still have long losing streaks, while a lower RTP game might pay out quickly. Volatility decides win frequency, not RTP alone.

Myth #3: RTP Is the Same as Volatility

RTP shows how much a game returns over time, while volatility is about win patterns. Two slots can both have 96% RTP. One pays small wins often, while the other pays rarely but big.

Myth #4: RTP Is the Same as Payout Speed

RTP measures how much a game returns over time, while payout speed tells how fast the casino processes withdrawals. A game can have a 99% RTP, but slow cashouts or quick payments on low RTP titles.

Myth #5: Strategy Can Increase a Game’s RTP

Most games, especially slots, have fixed RTP that no betting system can change. You can’t push a 97% slot to 100% as the house edge is always there. Only skill-based games let you reach the actual RTP with correct play. 

Myth #6: RTPs Are Rigged

Licensed casinos use certified Random Number Generators (RNG) tested by agencies like eCOGRA or iTech Labs. Rigging would cost operators their licence. Meanwhile, you can verify outcomes yourself for provably fair crypto games.

Myth #7: RTP Is the Same as the House Edge

A 98% RTP game has a 2% edge, but that’s calculated across millions of spins, not your personal play. RTP isn’t your chance of winning, just a long-term measure of returns.

Expert Tips for Finding and Playing at The Best Payout Online Casinos in the UK

Playing at the highest-paying casinos is about making informed choices. By focusing on where and how you play, you can maximise your chances of getting the most value for your money. 

Follow our 5 simple tips to get more from the best payout sites.

• Check Game Info and Choose Wisely: Always check a game’s RTP. Stick to slot titles with 96% or higher payout rate. For table games, choose options with better rules for stronger long-term value.
• Understand Swings in Casino Games: Even high-RTP games come with variance, so expect both winning streaks and dry spells. Knowing this helps you manage your balance better without being surprised by the ups and downs.
• Claim Bonuses and Promotions: Use bonuses, free spins, and cashback to stretch your bankroll and boost your effective payout. Clear wagering on high-RTP games whenever possible so the extra funds work in your favour.
• Use Fast & Low-Fee Banking Methods: Pick payment options like credit cards and crypto for quick, low-cost withdrawals, or bank transfers for bigger sums. Verify your account early to avoid delays. The best payout casinos online pay the fastest when you complete all ID checks.
• Take Breaks and Don’t Chase: Cash out part of a big win instead of chasing streaks. If luck isn’t on your side, step away and return another time.
