Well, we at we have managed to round up the Top 20 Online Casinos UK to help you. We’ve gone through and individually reviewed each and every aspect of the casinos to make sure you get the best possible experience.

Take a look at our Top 20 Online Casinos UK below.

What Are Online Casinos?

Online casinos are pretty self-explanatory. They allow users to play casino games on their PCs, laptops, smartphones and tablet devices. Users can play a huge number of games whenever and wherever they want while potentially, and hopefully, winning real money in the process.

Online casinos began appearing in the mid and late 1990s and have become incredibly popular over the last few years due to wide range of games and fantastic user experience offered.

Different Types of Casino Sites

As mentioned, users can play on their PCs and laptops through internet browsers, such as Chrome or Internet Explorer, or by downloading the casino software to the computer. Besides, users can also play on their smartphones or tablet devices either in-browser or through downloadable apps. How to play depends entirely on the player; do you want to download something directly to your computer or phone, or would you rather visit the casino like any other website.

We recommend users play through their web browser as it doesn’t take up storage space on your device and users have instant access to all of the available games. It’s never been better to play through your web browser too, especially on mobile devices.

The top online casinos are all mobile-friendly and offer an experience parallel to that of PCs and laptops, so you don’t need to worry about lousy performance or technical issues when using your mobile device.

Gaming Software Developers

There are a number of online casino game developers working hard to create fun and exciting games for users. Some of the games created include traditional table games such as poker, baccarat, and roulette as well as slots and live casino games, but more on that.

Microgaming, Playtech, and NetEnt are three of the most popular games developers. They’ve all been around for over 10 years and shaped the industry like no other. Let’s have a look at what each company has been up to over the last few years.


Microgaming is probably the most famous online casino developer. The software company launched in the early 1990s when they released what’s thought to be the first ever online casino. They’ve since gone on to become a leading provider and developer due to their focus on customer experience over anything else.

The firm creates exciting and fun games which are known to push boundaries. They also prioritise quality and design, making sure the game is fun to play and features jaw-dropping visuals and sound effects. They’re even responsible for creating the explosive Mega Moolah progressive jackpot slots game, which allows users to win large sums of money.

Today, Microgaming has won numerous awards including Gambling Online Magazine’s 2003 Top Casino Software award, the Best Casino iGaming Software award and an Editor’s Pick Award. While winning all of these awards, Microgaming worked to make itself available in over ten languages and to offer over 300 fun games.


Playtech is a huge online casino developer. They’ve made some incredibly popular games. Playtech has been around for 20 years and has cemented itself as one of the top providers in the online gambling industry.

The firm prides itself on offering a great selection of games and variations, offering a generous selection of bonuses and promotions as well as providing players with great 24/7 customer service.

Playtech stands out thanks to their immaculate work on graphics, special effects and attention to detail. Playtech’s games are incredibly user-friendly so that anyone can play them, and they provide players with lots of opportunities to win. If that isn’t enough for you, Playtech is the king of progressive jackpot slot games as well as licensed slots games.

In February 2017, Playtech struck a massive deal with film studio Warner Bros. to develop and release many DC Comics licensed Slots games including Justice League, Suicide Squad, Man of Steel and much more.


NetEnt is another popular online casino provider. They’ve been creating fun games for over 20 years and has managed to make a series of well-designed slots and casino table games for users. NetEnt is so popular that they held the official Guinness World Record for paying out the largest online casino jackpot worth €17.8 million through their popular progressive slot Mega Fortune.

NetEnt also makes sure to satisfy and please their customers by offering them some great bonuses and promotions. This can range from extra spins to fun and exciting bonus games. They even create individual promotions dedicated to some of their popular games such as Gonzo’s Quest and Steam Tower.

If that isn’t enough to impress you, this will! In 2017, NetEnt’s gaming servers handled over 41.2 billion transactions. In addition to that, they serve over 200 of the world’s most prominent online casinos and offer more than 200 games to their dedicated players.


Many of the casinos that made our Top 20 Online Casinos UK feature an expansive list of popular games. Most of the games offered at online casinos are those featured at real-life casinos. However, many online sites provide special variations that you wouldn’t be able to play anywhere else.

Some of the traditional casino table games offered at online casinos include roulette, blackjack, poker, and baccarat. Some websites also offer mahjong, craps, and pai gow. As mentioned, there are numerous variations of these games too including European and American roulette, pontoon blackjack, punto banco baccarat and much more.

Online casinos also offer slots games. This can range from the traditional three-reel fruit slots to video slots featuring fantasy or animal themes. Some are based on recent movies and television shows such as Game of Thrones, Jurassic World and Suicide Squad.

But there’s more! Users can also play at live casinos! This is where users can play their favourite table games with a real-life dealer who is being streamed directly to the player over the internet. The player can interact with the dealer through a messaging or chat room and the dealer responds through the stream.

Bonus and Promotions

Online casinos also offer a better range of bonuses and promotions. Online casinos always want more customers, so they’re continually changing their promotions. It’s a good idea to keep an eye on a casino’s promotions or special bonuses as you might just come across an excellent deal.

It’s also important to read the terms and conditions regarding bonuses and promotions because most casinos have deposit limits players will need to trigger to receive their rewards.

Registering and Selecting a Casino

Users are entirely free to register at one or more of our Top 20 Online Casinos UK. In fact, it’s never been easier to register! The only problem you might encounter is selecting a casino to play at.

When searching around for a new casino, it’s crucial users think about what matters the most to them. Do you want a more extensive variety of games? Do you want the best customer support or security available? Do you want better promotions and bonuses?

Once you’ve worked out what you’re interested in, you can take a look at our Top 20 Online Casinos UK list and browse through to find a casino that appeals to you. We only recommend online casinos that are proven to be safe, reliable and fair to play.

After selecting a casino, you’ll have to register with them. This is done by heading to their website and clicking the ‘Sign Up’ button. You’ll be required to provide details such as your address, date of birth, name and more to register. When you’ve completed your registration, some casinos will ask you to verify your account by using your email address or telephone number. After this, you’ll be able to deposit money, select a game and start playing.

Security, Safety and Customer Support

Many people are worried that they’ll be scammed out of money for playing at an online casino, but we can guarantee that that won’t happen, particularly if you select a casino from our list of Top 20 Online Casinos UK.

However, online casinos are incredibly safe. It’s compulsory that all casino operators providing gambling services need to process a license issued by the UK Gambling Commission. To get a license, online casinos must adhere to the Commission’s strict rules including the safety and fairness of games as well as technical security and player protection.

Many online casinos use testing agencies to make sure their games are fair. One of the most popular agencies is eCOGRA (E-Commerce and Online Gaming Regulation and Assurance), which most casinos use. Meanwhile, other European countries will have their regulatory bodies which provide licenses too.

Customer Support

Customer support is a huge factor for many people. If they ever run into a problem or a technical difficulty, players want access to someone who can help them out as quickly as possible. Most casinos offer a live chat feature which is open 24/7, allowing users to contact team members and resolve their problem promptly.

Other casinos, however, aren’t so great at customer service. They might not have a live chat feature, or maybe they lack a phone number, and the only way to contact them is through a form on their website. This would mean players would have to wait minutes, hours or even days to hear back from the support team.

We recommend registering with casinos which offer a variety of contact options including phone numbers, email addresses, and a live chat feature. We’ve made sure to highlight which casinos offer excellent customer support in our list of Top 20 Online Casinos UK.
