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.
It’s not easy getting a spot on our lists, but the casinos below 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 more 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 – and 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.
One of the reasons so many of us look for brand new independent casinos is to take advantage of a strong welcome bonus. Midnite makes this easy with its no wagering free spins offer – not only that, but Midnite runs weekly rewards too, so you can top up on bonus spins frequently.
Did you know that more gamblers play on mobile devices now than on desktop? That only makes the Jackpot.com slick casino app even more appealing. You can access more than 500 slots, as well as a huge selection of global lotteries – anything you can do on desktop at this casino, you can do on mobile.
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 ELK Studios and Big Time Gaming, you’re spoiled for choice.
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.
Now that we've shared our top choices with you, let’s take a look at some of the things that make independent sites stand out from the crowd.
This way, you’ll be able to know for sure if a standalone casino is what you’re looking for.
Not every independent casino will check each of these boxes, but you'll find that the majority will have at least a few of these features.
Independent online casinos in the UK 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.
Because they're 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 bonus offers based on your preferred casino game.
Despite being smaller, all reputable independent casinos still adhere to strict licensing requirements. 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 – offering fair play, secure transactions, and responsible gambling tools.
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. In addition, they are often less strict around players changing payment methods more frequently.
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.
Firstly, you need to make sure that the casino is licensed and regulated by a reputable authority such as the United Kingdom Gambling Commission – which means it is operating legally and legitimately. All of the sites on our list of independent casinos are fully licensed by the UK Gambling Commission.
Next is the fun bit – looking for an independent online casino that offers an excellent range of games, including those that actually interest you. Independent UK casino sites often feature some of the more unique game which is great, but make sure that you like the selection on offer.
Next, you should 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 both generous welcome bonuses and excellent loyalty rewards with fair terms.
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.
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.
If you are spending time and money on the site, you should expect a great user experience. So, before you sign up, take the time to look at how the website has been designed and how easy it is to navigate across different devices – the site should be easy to use and have a clear layout and an intuitive interface.
Next, take 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 independent casinos may not have as much visibility as those larger brands, so it's recommended that you check out feedback from various sources.
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, including SSL encryption.
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 casino site in general – even better, you can do this without any financial risk.
Most great standalone casinos try to stand out from larger, mainstream casinos by offering a variety of unique and generous bonuses.
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.
Here are some of the main types of bonuses you should look out for at an independent slots casino:
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 a generous 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 – meaning they have been launched in the last 12 months – or brand new to our Hideous Slots listings.
Read about one of our favourites below.
PricedUp is a casino without sister sites that launched in 2024. This casino is a solid choice if you like sites with simple bonus offerings. PricedUp has a full UKGC licence, but it’s also affiliated with IBAS (Independent Betting Adjudication Service), showing their commitment to trustworthiness and transparency.
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 between these terms?
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.
Check out our favourite below.
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 they're a name you can trust.
One of the best things about independent online casinos in the UK is that they often work hard to stand out from their most established peers.
There are a few different ways that they do this, including by offering a wide variety of payment methods.
This means that players who sign up will have their pick of methods, and there’ll be something for everyone – whether they value privacy, convenience, or speed.
Read more about some of the most common categories below.
Debit cards are accepted at pretty much all independent online casinos, and are generally an easy and secure way to fund your account. Options usually include Visa, Mastercard and Maestro, and one of the biggest highlights is Visa Fast Funds, which facilitates withdrawals in under 2 hours.
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 – they offer instant deposits, but you must find alternatives for your withdrawals.. The most common options available include Paysafecard and Neosurf.
Bank transfers are great if you prefer a more traditional banking option. However, whilst deposits may not take too long, withdrawals often take several days to process, meaning this method is better if you want to make bigger transactions and aren't in a hurry to get to your wins.
With mobile gaming on the rise, mobile payments are becoming increasingly popular with players across the UK. These options let you make your deposits directly from your mobile – and they're typically a faster method. Ones to look out for include Apple Pay, Google Pay and Payforit.
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.
