Best Payout Online Casino UK
The best payout online casino in the UK is the ideal site for slots players. Usually, such sites are referred to as the ones which have the biggest game RTPs. In reality, it’s much more complex than throwing random numbers at players and categorising casinos by their average payout percentage. That would require an up to date list of all their games and RTPs which are applicable to the specific casino. And that is something that even the best slot sites don’t usually provide.
Instead, you should be looking at the bigger picture. Check if the casino offers your favourite games, preferably at the highest RTPs. Better still if they have some highest paying slots too. And don’t forget about progressive jackpots, fast payouts and bonuses, all of which can also be very important for maximising payouts. As a player, you too can use different strategies to tilt the odds in your favour, which we’ll also explore in this guide. For starters, below is a list of casinos that you should consider for the best payouts.

List of Highest Paying Online Casinos
Here’s our list of online casinos with the best payouts and not-so-great payouts. Note the differences in the RTP, in this case, the popular Book of Dead slot by Play’n GO. Although this doesn’t give a picture of each casino’s house edge across all their games, it can be a good starting point. It should be noted that all of these UK-licensed casinos are approved and otherwise reputable sites that we keep an eye on. This list was last checked and updated in January 2022, but feel free to double-check the stats yourself since they can and do change relatively often.
Best RTP Casinos
There are also online casinos that offer high RTP slots on an exclusive basis. One of such slot sites is Unibet, which has a separate games tab called Super Casino.
There you will find exceptionally high RTPs on a selection of popular NetEnt slots. Gonzo’s Quest MegaWays, Twin Spin and Guns N Roses are among them. Enjoy these slots at the 98% RTP configuration with real money or with the casino bonus.
Other casinos that offer exclusive RTP boost on slots include PlayOJO.
How to Find RTP at Online Casinos?
The RTP is short for the Return to Player and it is shown as a percentage of all bets. Usually, you’ll find it from each game’s info bar or paytable, but if you’re hearing this term for the first time then you’re not alone. The majority of online casinos, even the best payout online casinos in the UK, are simply not displaying them in places where regular players would see them. Plus, this hasn’t been much of an issue until lately.
Each game provider sets a single or a range of RTPs to their games. These go through rigorous testing and are approved by gambling commissions like the UKGC and De Kansspelautoriteit in the Netherlands. This process can take several months and is not as simple as just changing the numbers. Online casinos have to accept that RTP or choose from many for each specific game. Hence, don’t be surprised to find popular slots like Book of Dead with an RTP of 96.21% at one casino and with an RTP of 94.25% at another casino.
Why RTP Matters?
Why should you be interested in RTPs as a slots player? The Return to Player is the percentage of all the money wagered versus what the casino game pays back to its players over the long term. Book of Dead has an RTP of 96.21%, so every pound that you bet should get you around 96p in return? In reality, the return to player is calculated over billions of spins, so your actual winnings can and will fluctuate a lot over hundreds or even thousands of spins. This is where each slot’s volatility, hit frequency and other math comes into play.
The difference between the RTP of 94% vs 97% may not seem big at first but let’s take a closer look. On the one hand, we have a 6% house edge and on the other a 3% house edge. That’s a 2x difference in the house edge for the casino, not the player. That means if you have £100 and bet £1 per spin, you can, theoretically, expect to make 1,651 spins before the balance reaches zero with a slot that has an RTP of 94%. For comparison, you can make 3,301 spins or about twice as many with the same balance but playing a game that has an RTP of 97%.
Truth be told, those stats are generated in lab conditions. Plus, the games with lower RTPs may be tweaked in such a way as to compensate for the lack of theoretical return in some parts of the game and underperform in others, like the base game or bonus. But that’s a topic which we can address in more depth in a separate guide.
Depending on where you live, there could be certain restrictions as well. In jurisdictions like Malta, for example, there is a minimum limit below which the return to player cannot be legally set. Since May 2021, such a limit for all Malta-licensed casinos is 85%, which has been downgraded from the earlier 92%. Other jurisdictions like Curacao and Sweden, have no such limits at all, so if the market conditions allow, the casino operators can choose the lowest RTP setting possible for their games. Most recently in Germany, slot sites have been forced into offering games with lower RTPs just to cover their operating costs because of a new gambling law that introduced higher taxes.
Here is a brief overview of different RTP limits in different countries as of 2022.
|Jurisdiction||Lowest RTP possible||Gaming tax for casinos (excl. license fees)|
|UK||No limit||21% on profit (Remote Gaming Duty)|
|Malta||85%||0.40%-1.25% Compliance Contribution + 5% Gaming Tax on revenues|
|Netherlands||No limit||29% from gross gaming revenue|
|Germany||No limit||5.3% on turnover|
|Sweden||No limit||18% on revenue|
|Estonia||80%||5% on revenue|
|Curacao||No limit||2% corporate profit tax|
Top 10 Highest Paying Slots
Around a decade ago, the best paying slots had an RTP of around 95%, a figure that is significantly higher than of the land-based counterparts. Today the number is around 96%, which as explained above, is a significant improvement. Even though many classic casino table games have even higher RTPs than the majority of video slots, this has not negatively affected their attractiveness.
👍 Tip: Some casinos are excluding high-RTP slots from their promotions, so make sure to carefully check casino bonuses and their T&Cs to avoid any negative surprises.
To help you get started, I’ve picked 10 slots with the biggest payouts. I wanted to include different providers and titles which are otherwise fun to play. All game RTPs are available for UK players, meaning there’s no feature buy required to achieve them (as it’s usually the case outside the UK). How many of these have you already tried?
Book of 99, Relax Gaming, 99%
Book of 99 breaks the mold with a “book” slot that has the highest return to player of any other slot of this famous genre. For the most part, it plays the same way as you’d expect, including the free spins bonus with a special expanding symbol that can generate wins up to 12,000x. See the full review to see how the new progressive bonus feature works or try it out at the recommended casino.
Mega Joker, NetEnt, 99%
Welcome bonus for new players only. 5 free spins on Starburst, Spinsane or Joker Pro on registration (max withdrawal £100). Maximum bonus is 100% up to £100. Min. deposit is £20. No max cash out. Wagering is 35x bonus. Maximum bet while playing with a bonus is £5. Eligibility is restricted for suspected abuse. Cashback is cash with no restrictions. Skrill & Neteller deposits excluded. Cashback applies to deposits where no bonus is included. Play responsibly. Full T&C.
In Mega Joker the return to player can go as high as 99%! The reason why is the skill component of the game which activates with the Supermeter mode. Featuring only 3 reels and 5 fixed lines, this fruit slot is ideal if you love slot machines with nostalgia. Find it from one of our selected, best payout online casino UK sites and put your skills to the test!
1429 Uncharted Seas, Thunderkick, 98,5%
Whenever you feel like taking a voyage back in time, consider Thunderkick’s widely loved 1429 Uncharted Seas. This elegantly crafted slot comes in the shape and design of a centuries-old map. It’s great to look at, has Expanding Wilds and Free Spins; but the most enticing part of the slot is definitely super high RTP that goes all the way up to 98.5%!
Snake, Gamevy, 98.005%
Developed by a lesser-known British iGaming company called Gamevy, Snake is a slot game based on the popular and retro Nokia phone video game. It delivers wins of up to 15,000x bet and has an overall theoretical return to player of 98.005%. Get to the bonus game to play the actual snake arcade game and also have a shot at the jackpot!
Blood Suckers, NetEnt, 98%
This one is a true NetEnt classic. Blood Suckers was released over a decade ago. At that time there weren’t many video slots to match this game’s 98% RTP, which ultimately has given this game a significant advantage. Off the charts, it went, and many players love it to this day. Vampires, easy gameplay, and a low variance have made Blood Suckers immortal.
Starmania, NextGen, 97,867%
18+. New players only. One offer per player. Max bonus bet £5. Offer: 100% bonus match on 1st deposit + bonus spins. Value of bonus & number of spins depend on deposit amount: £20-£100: max £100 bonus + 150 spins on selected games; £101-£200: max £200 bonus + 100 spins on selected games; or £200+: max £300 bonus + 150 spins on the following game(s): Starburst, Gonzo, Aloha, Twin Spins and eligible NetEnt games. Winnings from spins credited as bonus and capped at £100. Bonus funds are separate to Cash funds, and are subject to 35x wagering the total bonus & cash. Only bonus funds contribute to wagering requirement. Bonus funds expire within 30 days; bonus spins within 72hrs. Affordability checks apply. Terms apply. BeGambleAware.org.
Rocking NextGen’s biggest RTP, Starmania has some nice Starburst feel to it. The return to player in Starmania is surprisingly high at 97,867%. If you are looking for a slot machine that can deliver lots of smaller wins at an even pace, Starmania is an excellent choice.
Wild Orient, Microgaming, 97.49%
Microgaming has hundreds of online slots, but the 243 Ways Wild Orient is undoubtedly one of their rarest thanks to the high return to player. Featuring the studio’s unique Hyperspins, the game will let you re-spin each reel independently at the end of each base game spin, without any limit. Use this feature to your advantage to increase the RTP from 96.52% to 97.49%. If you happen to enjoy this game but not the theme, then check out the studio’s Lucky Riches Hyperspins, which has the same RTP.
Restaurant Craze, PG SOFT, 97.45%
Deposit £/€/$10 or more and get a 100% match bonus up to £/€/$200, Freeroll tickets to play in up to 12 different Freeroll Battles per day for a period of 7 days and 11 Extra Spins in Starburst or Rook’s Revenge (if NetEnt not available). All Extra Spins are wager free. Match bonus wagering requirement: 35x your winnings. No max cashout limit. Time and game weighting limits apply. New 18+ customers only. Play responsibly. Full T&C apply.
Designed by a studio that is obsessed with creating great games for portrait mode, Restaurant Craze is ideal for players who want to try something new without compromising long-term payout. The game features crafty graphics and a feature with Expanding Wilds. This is a high-volatility slot with a maximum win potential of 5,000x bet.
Big Bad Wolf, Quickspin, 97.34%
18+ | New Players Only | Bonus spread over 1st 4 deposits | Spins applied in batches of 50 on 1st, 2nd & 3rd deposits | 1st: 100%. Min deposit €/$10 max bonus €/$100 | 2nd: 50%. Min deposit €/$20 max bonus €/$100 | 3rd: 25%. Min deposit €/$20 max bonus €/$50 | 4th: 100%. Min deposit €/$20 max bonus €/$50 | 35x wagering on bonus & spins | spins are credited on Starburst & expire after 24 hrs | T&C’s Apply
Big Bad Wolf is one of the most popular slots from Quickspin and also one of my personal favourites. Not only has it cascading symbols (Swooping Reels) but also a Pigs Turn Wild feature that transforms regular symbols into wilds. In this game, we’re also looking at a very healthy RTP of 97.34%!
Bork the Berzerker Hack n Slash, Thunderkick, 97.30%
This Scandinavian company has another high-RTP slot that you should consider, which centres around Old Norse mythology. Played with a whopping 97.30% Return to Player, this game promises wins over 2,000x bet through Expanding Wilds which will always expand on reel 2 in the free spins bonus.
Slot Developers with Highest Payouts
Ironically, as game developers are pushing the RTP limits, casino operators are being given more freedom to choose from many RTP variants for the same game. As a result, it’s increasingly important to know which game studios offer slots that have many RTPs:
|Developer||RTP variations||Affected games||Low RTPs||Preferred RTPs|
|Play’n GO||5||All||94%, 91%, 87%, 84%||96% and over|
|Pragmatic||5||All||94%, 95%||96% and over|
|Nolimit City||3||Many||94%||96% and over|
|NetEnt||8||Few||90%, 92%, 93%, 94%, 95%||96% and over|
|Push Gaming||3||Few||90%, 95%||96% and over|
|Quickspin||3||Few||90%, 94%||96% and over|
|Blueprint||2||Few||94%||96% and over|
|Big Time Gaming||1||None||None||Default|
👍 Tip: When in doubt about RTPs at casinos, choose the games from developers that offer just one RTP variant.
Best Online Casino Fast Payout
The next important step when picking the best payout online casino is cashout speed. Here are some tips that will help you when choosing casinos that process withdrawals as fast as possible:
- See our casino lists and reviews for quick guidance.
- Use a payment method that enables fast withdrawals, such as Visa Direct, PayPal or Apple Pay.
- Verify your account by sending or uploading KYC documents as soon as possible, preferably on the same day you sign up to avoid delays.
- Avoid casinos with long cashout pending times (the time between your submission and when the casino starts to process your cashout request).
If you are specifically looking for fast payouts, then see our dedicated guide to find the best fast withdrawal casinos in the UK. You also cannot go wrong with the top 10 casinos on this page, although it’s always good to double-check all the banking information on the site just to be sure. It is customary for licensed casinos to display such information on the site FAQs.
Best Online Slot Games to Win
So far, I have presented you with my top ten slots with the highest RTP. Although you will find a range of different titles from that list, the RTP is not by any means the only thing you should be looking at when choosing the best online slot game to maximise your win potential. This is because winning cannot ever be the only motivation to play. After all, the house always has the advantage.
That is why you should aim to choose the types of slots that you enjoy playing. What type of slots are you most interested in?
- Would you rather have frequent small wins or rare big wins?
- Do you like more features or fewer bonus games?
- Are you okay with a fixed jackpot or do you prefer a progressive one?
Those choices will have a significant impact on how the game will perform and what you would consider as “winning”. If you aim at winning big, then I would recommend you consider the games which have the biggest payout potential, slots with Daily Jackpots or games with progressive jackpots.
Slots With the Biggest Maximum Win Potential
When looking for the best online slot games to win at the best payout online casinos, look for game developers who have slots with a big win potential. You cannot go wrong with MegaWays slots. Developed by Big Time Gaming, this innovative game mechanic is also used by many other iGaming studios, including Blueprint Gaming, Red Tiger, Relax Gaming and Stakelogic. Companies like NetEnt, Push Gaming, Relax Gaming and Nolimit City also have popular games with above-average maximum wins. Here are some of the best examples:
|Tombstone R.I.P.||Nolimit City||300,000x||Insane||96.08%,94.08%|
|San Quentin||Nolimit City||150,000x||Extreme||96.03%, 94.11%, 90.11%|
|Dead or Alive 2||NetEnt||100,000x||High||96.8%|
|Hellcatraz||Relax Gaming||51,840x||Very high||96.83%|
|Wild Flower||Big Time Gaming||114,000x||High||96.52-96.59%|
|Rick and Morty MegaWays||Blueprint Gaming||50,000x||Med/High||96.55%|
|Jammin’ Jars 2||Push Gaming||50,000x||High||96.40%|
|Gonzo’s Quest MegaWays||Red Tiger||20,000x||High||95.77%|
Daily Jackpot and Progressive Jackpots
Every respectable online casino in the UK should have a range of progressive jackpot slots. Better yet, the very best of them will also have online slots with daily jackpots. Such games are practically no different from their standard version but also have an element of surprise – players randomly win extra jackpots throughout the day, week or month! The prizes are guaranteed to drop, which is what makes the games so tempting to play. You will find slots with daily jackpots from a dedicated page or section of the casino lobby. Developers that offer slots with must-drop jackpots include Red Tiger Gaming, Blueprint Gaming, Push Gaming and Pragmatic Play.
The best online slot games to win big are also the most popular progressive jackpots slots. NetEnt and Microgaming have many successful releases, featuring Mega Moolah Absolootly Mad, Wheel of Wishes, and Mega Fortune. Note that some of their games will have different jackpot values depending on where you play. See our progressive jackpots guide for tips and the biggest progressive jackpots in real-time.
Best Strategies to Get the Biggest Payouts
When it comes to the best payout online casino sites, are there any strategies for slot games? You won’t find the perfect strategy as you would for blackjack, because slots are not skill games but machines guided by a Random Number Generator (RNG). Depending on how that RNG is configured, you can apply different strategies and be ready for what the slot has to throw at you. Here are a few handy metrics which you should also find at each online casino:
- Volatility — As a rule of thumb, slots with higher volatility offer bigger payout potential.
- RTP – Shows long-term theoretical return to player. Generally speaking, the bigger the RTP the more spins you’ll be able to play. It’s also worth noting that tables games like blackjack and video poker offer higher theoretical returns than slots, and commonly have RTP above 99%.
- Bet size – Some slots trigger bonuses and feature more frequently when the bet is higher. Microgaming jackpot slots like Atlantean Treasures Mega Moolah will trigger the jackpot wheel every 4-5 spins with the maximum bet of 200 credits. The same goes for many of their other games which have lower, more accessible bet limits, but which will still make a difference to the way the hit frequency.
ELK Studios is another interesting developer which offers Betting Strategies with their slots. You can tell the game to lower or increase your bet size depending on if you win or lose, how much, and often. It’s a flexible feature that can be quite fun to play with.
- Jackpot boiling point – No fixed jackpot slot can compete with a mega jackpot slot which has also exceeded its jackpot boiling point. This means the network prize pool has grown bigger than the amount it usually drops at. And that means a much better probability that one lucky player will make history and become an instant millionaire. This also applies to daily jackpot slots, which haven’t paid out their daily prize at the final hours. Below is a list of popular jackpot slots like that, with a bigger real-time jackpot than usually.
- Tournaments – Seek for casinos that offer slot tournaments or races. This is a great way to kill two birds with one stone: play your favourite slots and take a chance at winning a share of the tournament prize pool.
- Slot bonuses – This is self-explanatory, as bonuses can be commonly used to your advantage when playing slots. Whichever bonus it is, I recommend you pay attention to its terms (see below). Better yet, choose a slots bonus without any wagering requirements!
Hopefully, these simple strategies will help you when choosing the best payout online casino in the UK.
Best Payout Casinos and Bonuses
When it comes to bonuses and payouts, there are a few things that you should keep in mind to find the best sites. Whether it’s deposit bonuses, free spins, cashback or other perks, they all come with terms and conditions. These rules are meant to protect casino interests and can vary widely from site to site. Here’s what you want from the best payout casino:
- Game restrictions – Also known as game weighting, many casinos restrict bonus use on slots with high RTPs or with progressive jackpots. The clause that mentions game weighting in the T&C will usually tell you which games and how much they count towards the bonus wagering requirement. Consider playing at sites that let you play all slots, without exception.
- Maximum win limits — Some online casinos set a maximum win limit achieved from the bonus. This means that once you have met the wagering requirements, you get to keep up to a certain amount of money as real winnings. Typically, this restriction applies to no-deposit or signup bonuses and free spins, but it’s not unusual to find such a clause on prominent sites that you wouldn’t expect.
- Wagering requirements – This shows how many times the bonus or/and the deposit must be played through to claim bonus winnings as real money. You want a bonus with the lowest wagering requirement or one where only the bonus must be wagered, without locking your real money winnings (also known as non-sticky bonuses).
- Time limits – Usually there’s a time limit for the wagering as well. This means that you need to meet the requirements within a certain period. The more time is given, the better.
Those are the most typical restrictions that you’d find with casino bonuses: all vital when looking for slot sites with the best payouts. Here’s a selection of some of the most lucrative welcome offers which are available at the moment:
New Games customers only. Sign up using promo code ‘GAMES’. Deposit and stake £5 or more to receive 25 Free Spins on selected games from Blueprint Gaming (Eye of Horus, Fishin’ Frenzy, Genie Jackpots, King Kong Cash, Paws of Fury, Ted, The Naked Gun, Wish Upon a Leprechaun). Free Spins credited within 24 hours. Free spin equal to 20p per spin. The 25 free spins are only available on selected games. Any winnings from free spins will be paid as cash. Free Spins expire after 7 days. E-Wallet & Prepaid Card restrictions apply. SMS validation may be required. Full T&Cs apply.
18+. New customers only. Min deposit & spend £10 = £20 bonus. 20x wagering requirement applies. 30 Free Spins on Big Banker Slot. Spin value £0.10. 10x wagering on free spins. Bonus & Free Spins valid for 7 days. Payment restrictions & T&Cs apply.
Deposit and stake £50 and get a £5 bonus to use in the Evolution live casino games. Opt-in required. The offer must be claimed within 7 days of registration. Wagering requirement is 1x of the £50 deposit. All bonus winnings will be paid as cash. New customers only. 18+. Full T&C apply.

Certain deposit types excluded. Bets covering >70% of Roulette table excluded. T&Cs Apply.
Loyalty Programs and VIP Clubs
The best payout online casino UK sites can also include a loyalty program or a VIP club. This means that the more you play on the site, the better your benefits and prizes will get. Some VIP clubs are based on your progress as a player: you will not be invited to the club immediately, but once you have proven to be a loyal customer, the casino can extend an invitation for the more exclusive service.
Another way to get your hands on better prizes is loyalty programs. These are usually the ones you don’t need an invitation to, but instead, you’ll be a part of the program ever since your first real money deposit.
Both loyalty programs and VIP clubs can consist of multiple levels. Each level has better perks. These perks can be for instance:
- Your personal account manager
- Better and more frequent bonuses
- Invites to tournaments and exclusive events
- Faster payouts with no limits
- Prize draw tickets.
So, whether you are a low or high roller, additional player perks that come with the loyalty programs can turn an average experience into a fun one.
How to Spot Fairest Online Casinos?
What’s the use of the best payout online casino if it won’t pay out?! That’s why when choosing the best payout online casino UK site, it’s important to ensure that it’s a fair and safe operator. What types of indicators for fairness are there?
- The online casino shows the name of the operating company
- The casino tells you the license numbers
- There are information and tools for responsible gaming
- The online casino is deemed trustworthy by us.
The Safety of Online Casinos with Best Payouts
The indicators mentioned above are the signs you must check when signing up at a new online casino. If you don’t want any hassle then go for our recommended casinos, which we have investigated and are regularly in touch with as independent affiliate partners.
When exploring the slot sites for yourself, remember to check the footer for all the necessary and official information. The more transparent they are about different products and services, the better. This also goes for bonus rules and terms and conditions in general. Usually, when a casino is licensed by the UK Gambling Commission, then it already meets many of the requirements aimed at providing a safe and fair environment for its customers.
Not all UK casinos are created equal, especially when some of them can easily be duplicated. While these “white label” type skin sites are certainly not rogue if they carry the UK license, their life online is often short-lived. And that is something to keep in mind when you’re the type of person who is not fond of changes.
As a result, because such casino networks exist and successfully provide new sites with all the best content, it’s no longer viable to tell safe and unsafe casinos apart just by looking at its games or payment methods. When in doubt, see if we have a review or check online for any issues that might have come up with other players.
Responsible Gaming at Best Payout Online Casino UK
Finally, the best payout online casino UK sites have tools and information about responsible gaming. For your own safety, you should be able to set up deposit, betting and time limits without any hassle. Usually, they have them in the player account area. In rare cases, they will ask you to set it up through customer service.
The best payout online casino UK sites are easy to find if you know how to spot them. It is not a matter of looking only at the game RTPs but also other factors which set the ground for the best possible customer experience. Players who also consider different slot strategies, bonuses and payment methods are more likely to maximise their long-term payouts. Hopefully, our guide and know-how have taken you one step closer to finding the best payout casinos.
It’s nearly impossible to determine which one is the best payout online casino UK site. This is because the game selection and services are constantly updated on each site. The best casinos with the best payout rates should have everything from a wide selection of games to lucrative player promotions and services.
The best online casino in the UK is simply the one that suits your needs the best. It’s impossible to rank casinos when each player is an individual with their own preferences. On the other hand, if we look at the casinos based on the best payouts alone, then look for sites that offer you a good choice of slots with the highest RTP.
Yes, absolutely. Using your real money and any bonus money that the casino is offering you can also leverage your chances of winning. Refer to our guide for strategies and slots with higher Return to Player to maximise your payout.
RTP means a theoretical long-term return to player: total money wagered minus total winning paid over billions of spins. RTP is expressed as percentages. The average RTP for online slots is 96%. Note that the actual return can deviate a lot from the mean, and even a 2% difference can mean thousands of spins less played in the short run.
The average payout in online slots is around 96%. There are some slots with RTP above 97% and in very rare cases 98%. Then there are unicorns like Thunderkick’s 1429 Uncharted Seas with 98.5%, as well as NetEnt’s Mega Joker and Relax Gaming’s Book of 99 slots with 99% RTP!
