An independent casino is any gambling site that doesn't work with the network of larger, well-known casino brands. Lots of people choose brand new independent casinos because you can be sure that you can claim a welcome bonus. But that’s not the only reason to like them.
Unlike many of the mainstream casinos – which often have very similar game libraries and use all the same software providers, independent UK casinos often run on their own or less common software platforms.
This gives them an interesting and unique edge as they often offer exclusive games and innovative features that you won't find at the larger, more commercial sites.
In our view, the best independent casinos are able to offer you a refreshing alternative to the more mainstream gaming sites – which means they can stand out from the crowd and are a great option if you're looking for something a little different!
Before we share our top 5 independent online casinos with you, let’s take a look at some of the things that make these sites stand out from the crowd. That way, you’ll be able to know for sure if a standalone casino is what you’re looking for.
Independent UK online casinos often feature their own bespoke collection of slot games, table games and other cool casino games. What's more, you'll often notice that these titles have been developed either in-house or by smaller, niche software providers, so you can expect a unique gaming experience that you won't find at the more mainstream sites.
Because they are smaller in scale, the best independent online casinos can – and do, provide a more personalised and intimate gaming experience. This often means that you can expect better customer service, tailor-made promotions and deposit bonus offers based on your preferred casino games, and an actual sense of community with other players on the site.
Because they don't have the same massive marketing budgets that the big casino brands have, independent casinos tend to focus more on making sure that they offer excellent gameplay and user experience. As such, you'll often find well-thought-out game designs and various other innovative features that put player enjoyment at the forefront of everything.
Despite being smaller, all reputable independent casinos still have to adhere to strict regulations and licensing requirements – and they should all be licensed by the UK Gambling Commission in order to operate legally within the UK (as are all of those on our list). They make sure that they offer fair play, secure transactions, and responsible gaming tools and practices so you can be assured of a safe and trusted online gaming environment.
You'll often find that independent casinos are also more flexible when it comes to payments and deposits. They tend to offer a wide selection of payment methods and low minimum deposit requirements to get people playing.
It’s not easy getting a spot on our lists, but these casinos have managed it. All of them are completely independent, offering an experience that’s different to anywhere else. Some are long standing favourites, while others are new independent casinos that have launched recently.
Whichever you choose, you know each of these standalone casinos has been put through its paces and exceeded our expectations.
Playing at an independent casino site shouldn’t mean you settle for less choice of games – or that’s clearly what Lottomart thinks. Their catalogue boasts over 3,000 slot games and a whole host of lotteries too. There’s a super modern app to download as well, plus a generous welcome bonus of 100% up to £200 and 100 Free Spins.
One of the reasons so many of us look for brand new independent casinos is to take advantage of a strong welcome bonus. Midnite casino makes this easy with its no wagering offer of 100 free spins when you deposit and play with £20. Not only that, Midnite runs weekly rewards too, so you can top up the bonus spins whenever you want.
Did you know that more of us play on mobile now than on desktop? That only makes Jackpot.com’s super slick casino app even more appealing. You can access more than 500 slots, as well as a huge selection of global lotteries.
Sometimes standalone casinos specialise in offering games from smaller game studios, but not at Quinnbet. This independent online casino has a 3,000 strong slot catalogue that’s made up of heavy hitting providers. From Evolution to Games Global, ELK Studios to Big Time Gaming, you’re spoiled for choice when it comes to blockbuster titles.
If you enjoy switching slots for sports from time to time then Kwiff is a great choice. This casino launched back in 2015, but has continued to innovate ever since. From their exciting supercharged odds that strike at random, to regular flurries of free spins to your inbox, Kwiff do it differently – in a really good way.
Given that there are more and more brand new independent casino sites hitting the UK market, picking the right one for you isn't necessarily an easy task.
However, getting it right is important, as making the right decision can really improve your online casino experience.
Here are some of the factors you should think about when choosing the independent casino site you want to sign up with.
These are also factors that we look at when we recommend an independent casino to you, so you know any of our hand selected independent sites will be the perfect option.
First of all, you need to make sure that the casino is licensed and regulated by a reputable authority such as the UK Gambling Commission (UKGC) – which is essential as this means that it is operating legally and legitimately.
As well as this, a valid licence also guarantees that the casino has to adhere to the strictest standards of fairness, security, and responsible gaming.
All of the sites on our list of independent UK casinos are fully licensed by the UK Gambling Commission, so you won't need to worry if you’re taking one of our recommendations.
Next is the fun bit, looking for an independent online casino that offers an excellent range of games – and that offers games that actually interest you.
Independent UK casino sites often feature some of the more unique games that have been developed in-house or by smaller software providers – which is great, but make sure that you like the selection on offer.
Check to see that the site offers your favourite types of games – whether they be online slots, table games, live dealer games, specialty games or something else.
It's also a good idea to look through the casino's various bonus offers.
You often find that independent online casinos in the UK tend to offer the best casino bonuses to attract players away from the more mainstream sites.
Keep an eye out for generous welcome bonuses, no-deposit bonuses, free spins and bonus spins, and, ideally, excellent loyalty rewards and VIP schemes, etc.
Remember, you should always read the terms and conditions to understand wagering requirements and other restrictions.
Any good independent online casino site will make sure that the terms are fair and transparent so you don't end up with any nasty surprises when you go to withdraw your winnings.
You should also check that the casino supports your preferred payment methods for both deposits and withdrawals.
The best independent slot sites will have a whole variety of options, including debit cards, e-wallets, bank transfers – and some of the new independent slot sites even offer prepaid cards.
You should also take the time to check whether there are transaction fees, what the processing times are, and any limits on transactions.
One of the biggest signs that a casino actually cares about its customers is that it offers a solid customer support service.
While we hope that you don’t run into any hurdles on your slots adventure, sometimes it happens. When it does, reliable and professional customer support is absolutely vital.
That's why you should check to see if the standalone casino offers a variety of support channels to get in touch with them – such as live chat, email, phone support and ideally, social media.
You might even want to test out the responsiveness and helpfulness of the support team before you actually commit any money. We do exactly this in all of our tests!
If you are spending time and money on the site, you should expect a great user experience.
So, before you sign up and spend money, take the time to look at how the website has been designed, how easy it is to navigate, and the overall user experience from start to finish.
The site should be easy to use and have a clear layout and an intuitive interface.
Mobile compatibility is also important, especially if you are someone who prefers to play on the go, so check if the casino offers a mobile-friendly site, a dedicated mobile app – or both.
It might also be a good idea to take a bit of time to research the casino's reputation.
This can be done by looking up player's online casino reviews and various expert opinions.
You'll find that UK independent casino sites don't necessarily have as much visibility as those larger brands, so it's recommended that you check out feedback from various sources.
Look to see if there are comments on the fairness of the games, reliability of payouts – and overall user satisfaction.
Security is absolutely essential in the world of gambling online.
With money and personal information being disclosed, it's important that you make sure that the casino uses the most advanced security measures to protect your personal and financial information.
This includes SSL encryption, so you know your data is always secure.
Check to see whether the site has a clear and understandable privacy policy and various responsible gaming tools and measures in place.
Some independent casinos also offer you the option to try out the games for free before spending any of their own money on the site.
This means that you can get a feel for the games and the whole new UK casino site in general.
Even better, you can do this without any financial risk.
By trying the casino first before depositing any of your own hard earned money, you can check out the features on offer and whether or not it's worth depositing into, completely risk free!
Most great standalone casinos try to stand out from larger, mainstream casinos by offering a variety of unique and generous bonuses.
Before deciding whether or not these bonuses are worth claiming, you need to learn a bit about them.
Understanding these different types of bonuses can help you not only to maximise your playing experience but also potentially increase your chances of winning.
You may even find that some casinos spread out your welcome offer over your first three or four deposits.
Simply make sure you make the minimum deposit required, and you'll get lots of bang for your buck to get started.
So, here are some of the main types of bonuses you should look out for at an independent slots casino.
This offer is the most common type of welcome bonus.
This bonus isn't too dissimilar to those found at bigger casinos – although they might be larger than standard offers.
Basically, the casino will match a percentage of your first deposit up to a certain amount.
So, for example, a 100% match up to £500 means that if you deposit £500, you'll get an extra £500 to play your favourite games with.
Some casinos will offer you a bonus just for signing up, without needing you to make any deposit at all.
These welcome bonuses are normally smaller than the standard welcome bonus but are completely free. They do come with wagering requirements, that you’ll need to complete before you withdraw your winnings.
These bonuses can come in the form of free bonus money (usually between £5 to £20) or no deposit free spins (normally around 10).
This is an excellent way for you to try out the casino's games and services with zero risk.
Free spins, sometimes referred to as bonus spins, are hugely popular with slots players. As well as often being part of a welcome package, free spins can also be given as standalone promotions.
These can be given out for different reasons, such as a new game release, special events or holidays, or as part of a loyalty program.
Some casinos even offer regular free spins bonuses – like ‘Free Spins Fridays', where you just need to make your qualifying deposit, and they're all yours.
Free spins basically let you play online slots, like megaway slots, without spending your own money and keep what you win – obviously subject to terms and conditions.
Reload bonuses are designed for existing players to encourage them to keep making deposits into their account (or to encourage them to make another deposit if they haven't been active on the site for a while).
They work similarly to welcome bonuses but are available on your other deposits.
Depending on the site, these bonuses can be offered regularly (weekly or monthly, etc) and can be a great boost to your bankroll.
They are generally smaller than welcome bonus offers – but still well worth your time.
Lots of brand new independent casinos offer cashback bonuses, which provide you with a percentage of your losses back over a set period of time.
This type of bonus can be very appealing, as it can reduce the pain of those annoying losing streaks.
So, for example, if a site offers a 10% cashback bonus, it means that you'll get back 10% of your net losses over that week.
So, if you make an overall loss of £50, you'll get back £5.
Cashback bonuses often have lower wagering requirements – and some come with no wagering requirements at all – making them even more player-friendly than other offers.
The best independent casinos will also make sure that they reward their most loyal players through loyalty programs or VIP clubs so they aren't tempted to look elsewhere.
These can vary from casino to casino, but generally, as you play, you earn points that you can exchange for bonuses, spins, prizes or cash.
If you manage to work your way up to the higher levels, you might even receive even more impressive and exclusive perks.
These can include your own personal account manager, faster and higher withdrawals, and special promotions – even holidays and other tangible rewards.
Independent gambling sites often host slot tournaments and other competitions to add a little bit of excitement to your experience.
By taking part in these events, you can earn all sorts of goodies.
This often includes bonus credits, free spins, or even cash prizes and other rewards.
These tournaments really can add an extra layer of competition to your gameplay – giving you the chance to go up against other players.
You should also look out for bonuses that are linked to holidays, other major events (like sporting tournaments or fashion festivals, etc).
You could even see special bonuses if there's a big new game release.
These special promos often include big bonuses and more unique rewards.
So, for example, a Halloween-themed promo could offer you bonus cash, free spins on a spooky-themed slot – and various other treats.
Referral – or refer-a-friend bonuses, as they are sometimes called, reward you for introducing new players to the casino.
When your friend signs up to the casino using your special referral link and makes a qualifying deposit, both you and your friend will be given a bonus as a reward.
This type of bonus is a win-win, as it rewards you and your friend – and it expands the casino's player base.
Refer a friend bonuses can include cash rewards and free spins.
There's nothing a casino likes more than high-roller players…
This is the reason why they tend to make sure they are justly rewarded.
This is great news if you're a player who likes to bet big – as high-roller bonuses provide huge rewards if you're prepared to make large deposits.
These bonuses are tailored to high-stakes players, and they generally offer larger match percentages, higher maximum amounts, and sometimes even various other perks like exclusive VIP status or personal account managers.
One of the most important factors you need to consider when deciding whether or not to claim the welcome bonus is the wagering requirement attached to it.
This essentially dictates how many times you need to bet the bonus amount (or sometimes the bonus plus the deposit) before you can withdraw your winnings.
Wagering requirements (sometimes called playthrough or rollover requirements) are normally expressed as a multiplier.
So, for example, if you receive a £200 bonus with a 30x wagering requirement, you need to wager £6,000 (30 times the bonus amount) before you can withdraw any of the winnings you get from that bonus.
These aren't specific to UK independent online casinos.
Most casinos include wagering requirements in the T&CS to make sure that players can't simply withdraw free money.
These requirements are there to encourage you to play the casino's games with your own money.
By adding wagering requirements, it gives the casino a fighting chance as it can't afford to give away free money.
Depending on the independent casino you choose, there are different types of wagering requirements…
Before attempting to fulfil those wagering requirements, it is worth noting that not all games contribute equally to wagering requirements.
Normally, you'll find:
It's also important that these casino bonus offers come with fair and transparent terms and conditions. Here are some of the main ones you need to understand before claiming…
Looking for new casinos without sister sites is no easy task, new casinos pop up all the time, but new independent casinos? They’re launched much less often.
Whether you’re looking for brand new independent casinos because you want to guarantee you can claim that welcome bonus, or because you just want a totally fresh experience, we think these new standalone casinos in the UK could be just what you’re looking for.
These casinos are either brand new (launched in the last 12 months) or brand new to our Hideous Slots listings.
PricedUp is a casino without sister sites that launched its online casino offering in 2024. This independent casino is a solid choice if you like sites with simple bonus offerings. Their welcome bonus nets you 90 free spins for a £30 deposit, to be used on the classic Big Bass Bonanza.
Of course, PricedUp has a full UKGC licence, but it’s also affiliated with IBAS (Independent Betting Adjudication Service). This shows PricedUp’s commitment to trustworthiness and transparency, something we can all appreciate.
If you’re looking for somewhere to play slots as well as place sports bets then finding independent gambling sites is the key. Gentleman Jim is a new independent gambling site that was launched in 2024.
Gentleman Jim epitomises what it is to be a standalone casino in the UK, with a totally unique and very British flare. The casino isn’t massive yet, but it’s growing all the time. There are currently over 400 slots with lots of games you’ll know and love. Fans of horse racing and football will also find solid odds on a huge range of markets.
You’ve probably guessed from our name that at Hideous Slots, we love slot games. Some of the independent casino sites that we’ve mentioned already could definitely be considered independent slot sites, but what’s the difference?
An independent slot site is any independent online casino that has a really strong selection of slots. By that, we mean over 1,000 games from a slew of excellent game studios. When you scroll through the catalogue you’re hit with slot after slot that you know and love.
Slots Temple takes our top spot for the best standalone slot site for 2025. This slot site started out as a slot review site, but has recently launched more than 1,000 real money slot games that you can play on site.
This is a great starting point for any independent slot site, as you already know that Slots Temple is a name you can trust. They’ve been telling you the truth about slot games for years and now they’ve hand picked a catalogue of slots that’s made up of only top tier providers.
The great thing about independent online casinos in the UK is that they usually offer plenty of different payment options.
Here are some of the most common payment methods that you'll find at most…
Debit cards are accepted at pretty much all independent online casinos.
They are generally an easy and secure way to fund your account and are familiar to most people.
Options usually include
Debit cards usually offer instant deposits, although withdrawals might take 1-5 business days to process.
Tip: If you’re a Visa user then look out for independent casinos with Visa Fast Funds. This can see you get your winnings in under two hours.
E-wallets are becoming hugely popular mainly because of their speed and convenience.
They are very secure and tend to offer much quicker withdrawals compared to other banking methods.
Some of the most popular e-wallet options you'll find include PayPal, Skrill, Neteller and EcoPayz.
Deposits are usually instant with e-wallets, and withdrawals are processed within a few hours to a day, depending on the casino.
Prepaid cards and vouchers are perfect if you're particular about managing your spending or you don't want to use your bank account for online gambling.
The most common options available include:
They offer instant deposits but don't normally allow for withdrawals, so you'll need to choose an alternative.
Bank transfers are great if you prefer a more traditional banking option.
While deposits might not take too long, withdrawals often take several days to process.
This method is great if you want to make bigger transactions and aren't in a hurry to get to your wins.
With mobile gaming being on the rise, mobile payments are becoming increasingly popular.
These options let you make your deposits directly from your mobile.
Ones to look out for include:
Mobile payments are typically instant, but you'll need to check if you can withdraw via this method, as it varies from casino to casino.
There are all sorts of reasons you might want to sign up for an independent casino rather than a mainstream site.
These independent sites can give you a quirky and unique gaming experience with all sorts of exclusive and niche games, offering various innovative features you won't find at those bigger names.
They tend to offer a more personalised customer service, with more flexible and generous bonus offers, so you get an even better experience and even more value. Not to mention, you’ll always be able to claim the welcome bonus – as there’s no chance you’ve already claimed it at a sister site!
So, look through our list of top independent casino sites, pick the one you like the look of and take the road less travelled!
An independent casino is one that operates using its own software platform, usually offering unique games and experiences that you won't find at a mainstream casino. Most casinos in the UK are owned by a handful of brands, so it’s exciting to find a brand new standalone casino to try out.
Yes, our recommended independent casinos are fully licensed and regulated by the UKGC, so you can be assured of fair play and security. If you’re looking for independent casinos to try out on your own then always look for that UKGC licence.
Yes, independent casinos need to stand out from the crowd, which can be a huge benefit to you! This means they often provide even more attractive bonuses than mainstream casinos, including welcome offers, free spins, reload bonuses and plenty more too.
Standalone casinos usually accept all sorts of payment methods, including debit cards, e-wallets, bank transfers, mobile payments and sometimes prepaid cards. Opting for e-wallets is usually your fastest option, but Visa Fast Funds can be a great choice too if you want to get your winnings quickly.
Yes, most independent casinos all have fully optimised websites or apps, so you can play on the go. Because they have their own platform, you’ll often find that the apps of independent casinos feel fresh and unique compared to other sites.
The point of a true standalone casino is that it’s not part of any casino group, it’s entirely independent. All of the independent gambling sites that we’ve recommended on this page are completely independent. However, you will sometimes find other sites use the definition a bit more loosely, to mean casinos that are part of a small group.
The biggest benefit of signing up to an independent casino operator is that you get a totally fresh experience. You can try out new games, a completely new interface, and benefit from a unique site. Also, many casinos that are part of groups won’t let you claim the welcome bonus at more than one site, with independent casinos, that’s not a problem!
It all depends on which independent operator you choose. The independent casinos on this page are all vetted by us, so you know that the bonuses are generous and have fair terms. If you’re looking for your own bonuses, then pay attention to those terms – and don’t rule out independent casinos! They often offer great value.
