Here's our top 10 online casino sites, handpicked by our experienced casino reviewers:
Online casinos in the UK, and indeed worldwide, can be categorised according to certain features or attributes they possess. As your complete online casino guide, we have recommended casino lists for all such categorisations, each with its own complete page.
Deposit offers, welcome bonus, free spins... It’s important to understand the many different types of casino bonus. The bonuses on offer are so massive, sometimes even extending into the £1000s.
These bonuses give you a percentage of your initial deposit as bonus credit. For example, 200% of a £50 deposit would be £100 - giving you a total of £150 to play with. Not bad!
One of the most popular promotions is the no deposit bonus. These are bonuses you can claim without staking any of your own money. These are much smaller than the bonuses you can get by making a deposit; usually £5-20 in bonus credit and/or free spins.
These are usually added as a sweetener to one of the bonuses mentioned already. Free spins give you a certain number of spins to use on selected Slots games - but be aware that any winnings you make while using free spins will usually be subject to wagering requirements.
This is one of the most important conditions attached to casino bonuses. Wagering requirements are designed to prevent players from taking unfair advantage of bonus offers.
A typical wagering requirement could be '35x' - meaning you need to bet the bonus amount 35 times before withdrawing it. The details the wagering requirements and other terms can be found in several places:
In 2018, over 55% of players logged in and gambled via their mobile phones. This represented a 4% rise on the year before, an incredible trend given that mobile gaming only really took off in 2008 with the dawn of the smartphone era.
As a result, online casino sites are heavily invested in mobile technology, with all either creating a mobile-responsive site or app.
Newer online casinos also tend to be designed and developed mobile-first, meaning they were created primarily for mobile users first with the desktop experience a secondary priority.
There’s some debate between players whether mobile browser or app is better for mobile games. At the time of writing, the experience is roughly comparable - browser and app both have their pros and cons.
You are using the same account regardless, so the choice is up to personal preference. Some people would rather save the storage space on their device for other things, while some prefer to have the slicker interface that comes with a native app.
Whilst casino sites differ in design, they all require basically the same process to be followed to become a member.
When you’ve found an online casino that ticks all the boxes, see the CasinoGuide step-by-step guide (including screenshots) for each stage of signing up to an online casino and completing the KYC check.
KYC stands for Know Your Customer, and is a check undertaken by casinos (and other regulated bodies like financial institutions) through submission of verifiable ID through a secure online gateway.
Put simply: your ID is compared with the information you entered during registration, and either confirms or denies you are who you say you are.
By law, all online casinos in the UK are required to verify the name, address, and date of birth for all online players who sign up at their casino.
KYC is necessary to ensure that all players are over the age of 18 and therefore legally able to gamble at UK online casinos. Regulations have been tightened by the UK Gambling Commission in recent years in an attempt to reduce the number of underage gamblers in the UK.
Research undertaken by the UKGC across 2016-2018 showed a small percentage of underage UK residents had illegally accessed online gambling services, including online casino sites.
Casinos have other requirements to meet which necessitate KYC checks further. Anti-money laundering regulations necessitate checks to ensure that your money hasn't come from an illegal source, particularly if you’re making large deposits to your casino account.
Online casinos in the UK are completely legal and regulated. All legal UK online casinos hold a license from the Gambling Commission - the official Government body charged with ensuring the fair and legal operation of all gambling services offered in the UK.
When the Gambling Act 2005 was passed, thereby making both online and offline gambling legal in the UK, the Government formed what is known as the Gambling Commission. Put simply, the Gambling Commission is the ultimate authority when it comes to all kinds of gambling in the UK.
It is a legal requirement for any online casino offering their services to UK players to have a license issued by the Gambling Commission. This license indicates that the casino abides by all of the various rules set out by the Gambling Commission.
Rules and laws enforced by the Gambling Commission include everything from consumer protections, responsible gambling measures, and dispute procedures - allowing you to play with complete confidence.
A Gambling Commission license is one of the hardest to get in the gambling industry. UK-licensed online casinos are held to some of the highest standards in the world.
Every UK online casino listed here on CasinoGuide.co.uk holds a license from the UK Gambling Commission.
The UK is known as one of the best gambling jurisdictions in the world. In 2005 they overhauled all existing legislation and created the 2005 Gambling Act. Here's an overview of the legislation they've enacted since.
Can't see the image? Here's the transcription:
The UK is one of the most regulated gaming markets and jurisdictions, which works out perfectly for players and creates a safe, worry-free gambling environment.
By stopping unlicensed casinos from operating, as well as providing a whole host of other protections, the UK Gambling Commission is arguably one of the best licensing jurisdictions in the world.
For the main part, the regulation extends to the casino and how they engage with the player, forming a system of protections and rules.
This includes everything from how bonuses are advertised, to the separation of player funds, and creation of a safe gambling environment.
As licensing, certification, and RTP percentages must be obtained and published for all UK-licensed casinos, you know exactly where you stand with a UK online casino.
And crucially, you know that there are systems in place to hold the casino accountable by consumer and gambling laws if something goes wrong.
Despite the above, not all UK online casinos were created equal. Fortunately, when it comes to online casinos, we know how to tell a good casino from a less worthy one.
It’s easy enough to tell, when you know the right questions to ask:
Obviously, you don’t need to worry about this too much, as we’ve done the hard work for you. Our list of the top online casinos in the UK comprises the best of the best!
From Blackjack and Craps, to Slots and Roulette, online casinos in the UK have got it all. Here at CasinoGuide UK, you can find lists of online casinos that are most highly recommended for your particular choice of game. These can be found on our casino games page.
Whatever you want to play, you will find the ideal online casino website to play at right here on CasinoGuide. In addition, we provide in-depth strategy guides on all the most popular games, for beginners and advanced players alike.
The biggest UK online casino win on record is a whopping £13.2m. This was won in October 2015 by a British man playing the infamous Mega Moolah Slot, made popular by its massive, life-changing jackpot which never goes lower than £1m. Another Brit playing the Dark Knight themed Slot won £5.8m in 2012.
But these wins are dwarfed by the two biggest payouts ever seen in online casino games, which were both taken down by players on the continent.
Mega Fortune held the record for nearly six years with a payout of €17.8m, until it was smashed by Mega Moolah Mobile in September 2018 with a monumental payout of €18.9m.
It’s hard to imagine the feeling you would get if you suddenly won nearly £17m while playing on your mobile phone. But if you want to have a shot at it, you can try playing some progressive jackpot Slots and you could be next! Just remember to gamble responsibly.
Here at CasinoGuide UK, we only recommend the best online casinos which are regulated by the Gambling Commission, meaning they have been checked for fair gameplay practises. By playing at one of the top online casinos listed here, you avoid running the risk of playing games with odds that are more tilted towards the house than other casino websites.
With that said, it is important to note that all online casino games give the casino at least a slight edge over you, the player. This ‘house edge’ is there to ensure that the casino wins more than half of the time on average, over the long-term.
This is par for the course in casino games, and the good thing is that this information about your chances of winning is freely available – you can find it in our game guides. Here's a couple of examples:
Many UK online casinos have demo or practice mode for their Slots and RNG table games. This means if you sign up you can play for free, but without the chance to win real money.
You’ll still get all of the action though and get to try out different software, variations, and strategies while you’re at it!
Casino games vary from producer to producer, each with differing attitudes to graphics, game concepts, bonus rounds, game limits, jackpots, maths - basically, every game detail.
This means there’s an element of personal preference in deciding which developer's games you prefer - exploring UK online casinos' games libraries in demo mode is often the best way to find your preference.
After all, the games provided by a UK online casino should be a crucial factor when you're deciding if you want to play there.
Several market-dominating producers form the basis of most game libraries at online casinos in the UK. These are some of the biggest casino software providers in terms of library size and player following:
The best UK online casinos make use of the rich cornucopia of casino games on offer to create plentiful lobbies of the best and latest casino games. This, in turn, attracts new players while keeping existing players interested.
The biggest casino software providers have hundreds of games in their collection, which reflects just how long they’ve been operating for.
But these big hitters often also own smaller studios; a recent strategy is to acquire new studios to bolster and improve their own game portfolios - while the smaller studio benefits from greatly increased distribution under the brand of the established software provider.
For example, under Microgaming, you’ll also find games from the following studios:
This makes Microgaming software particularly competitive and current with several new games released each month.
Microgaming’s biggest competitor is NetEnt, an innovative studio which produces all its games created in-house. This guarantees the same sublime quality and slick graphics across all titles, albeit across a smaller portfolio (Microgaming has 650+ games, NetEnt 250+).
NetEnt is reputed amongst online players for driving innovation in games concepts, being at the forefront of graphics technology and for keeping the other software producers on their toes. The size of Microgaming’s game lobby is matched only by Playtech who have created more than 300 games.
There are many other rival software providers, big players who have been around since the 90s like Play'N Go or Scientific Gaming. Add to this all the newer breakaway software providers such as Yggdrasil, which split from NetEnt, or entirely new studios like Big Time Gaming and Red Tiger - each with something unique to add to your casino experience, and you get a highly competitive casino games marketplace.
Due to the heavily regulated gambling market in the UK, online casino transactions are protected by consumer law and there are plenty of fast, safe, and secure payment methods available.
The more payment methods a casino offers, the wider range of players they can attract, and the more flexible it is for you, the player.
The best UK online casinos offer the following types of payment options:
Some online casinos in the UK even offer cryptocurrencies now, but this is less common. Scroll up to our list of top-rated UK online casinos at the top of the page and use the filter to find a Bitcoin casino by pressing Deposit Options > Bitcoin. Or you can see them all easily on our dedicated UK-licensed Bitcoin casinos page.
For most payment methods, deposits are instant and processed through a secure payment gateway. Here's how a few of the more popular options work:
Withdrawals can usually take up to 3 working days, but VIPs can usually access express withdrawals. The casino must first process your withdrawal request, the best online casinos do this within 24-48 hours and then send the money to your account or e-wallet.
Betting duty in the UK used to be 6.75%, but since Gordon Brown’s 2001 budget as Chancellor of the Exchequer all gambling winnings have been tax-free. This includes online and land-based gambling.
How did Mr Brown go about this? He increased the flat rate charge for gambling operators to 15%, meaning only they are charged and the government did not lose any tax revenue. This is a huge benefit when withdrawing your winnings!

It's essential that you gamble responsibly while entertaining yourself at online casinos. Players are encouraged to self-regulate when it comes to gambling through responsible gambling tools, which must be provided by the casino under their licencing conditions.
These are the four most common ones:
As an addictive behaviour, gambling should only ever be a fun activity, not a behaviour you cannot control or feel compelled to engage with. To encourage awareness of gambling behaviours casinos must provide players with:
All gambling operators should also train their support services to recommend these tools and refer players to gambling support services where needed. The best casinos also have systems in place to keep an eye on their players, checking for irresponsible or addictive behaviours.
If you are in the UK and feel that your gambling is out of control or you require support to gamble responsibly, you also have a wealth of charity-based services at your disposal:
Many players that enjoy land-based casinos are put off from online casinos due to concerns that casino websites are rigged. Fortunately, UK online casinos are regulated and require a license from the Gambling Commission to operate. Hence, if you stick to playing at well-known, licensed sites like those featured in our list above, you’ll be in safe hands.
When signing up with an online casino, you'll want to be sure that your sensitive personal information is protected. At CasinoGuide UK, we only list secure, well-renowned, UK-licensed online casinos compliant with GDPR and the Data Protection Act. You can also take your own steps, like using a separate email address and only signing up at casinos which have an HTTPS connection (you can see this in your address bar).
Our comprehensive casino reviews contain all the information you need to make an informed decision on where to play. We judge casinos based on their games, the bonuses and payment options available, customer service, and more. We also give each of our recommended online casinos a basic star rating for at-a-glance convenience.
In short: basically all of them. Nowadays, you can enjoy online casinos on a wide variety of platforms and devices. This is thanks to the revolutionary creation of HTML5 software, which allows website features such as casino games to be written once and used everywhere. This has paved the way for games to be made available on laptops, tablets and mobiles.
Although players are not routinely banned from online casinos in the UK, this can sometimes occur. Online casinos reserve the right to ban players if they notice that they are trying to cheat the system, break their T&Cs, or if a player is playing from a location that has been prohibited (the UK is fine of course).
Online casinos that serve players in the UK are legal, as long as they are licensed by the UK Gambling Commission. All of the casinos we list here on CasinoGuide are perfectly legal and safe. Check out our in-depth guide on gambling licences to learn more.
When you win at an online casino the money is credited to your casino account. You can then use it to continue playing or head to the cashier and create a withdrawal request. Make sure you take a look at your casino’s terms and conditions before making this request as using some payment methods may incur fees, or there may be conditions such as using the same method to withdraw as the method used to deposit.
Or if you want to play strategically and up your chances by minimising the casino’s house edge, we recommend you play ‘skill games’ like Blackjack or Craps instead of games like Slots. To give yourself the best possible chance you’ll need to thoroughly learn the rules and strategies of the game – our game guides can help with this.
After joining the EU in 2004, Malta structured its economy to facilitate the iGaming industry. They created the Malta Gaming Authority so they could license software and casinos in-country, created favourable tax incentives and the tech infrastructure required for the industry. Together, this has made Malta one of the most competitive European bases for iGaming software and casinos and provided EU market access.
The best online casinos for UK players are the ones we recommend at the top of this page. We’ve thoroughly researched and vetted all of them for you in line with the CasinoGuide 6-point review technique, and have no qualms in recommending any of them.
Because they are safe and secure online portals of fun available at the touch of a fingertip, so why not? Unlike land-based casinos, they have no dress code and require no travel. They are also able to offer more competitive deals, lower minimum bets, and sometimes even better odds, as they have less operational costs to cover. Online casinos are an all-round winner, especially in territories like the UK where player protection is ensured by a very robust regulator.
To sum up, playing at online casinos in the UK is:
✅ Completely legal and safe, thanks to Gambling Commission regulations
