Top Online Casinos in the UK 2020

How can you tell a good internet casino from a lame one?

The thing is:

In most cases, you can’t, not at first glance anyway. You’d have to do a thorough background check on the casino before you trust them with your money. If you’re just getting started with online gambling, it can easily get overwhelming.

Think about everything you’d have to go through: licenses, restricted countries, terms and conditions, promotional terms, wagering requirements, hidden withdrawal fees and catches… Geez.

Thankfully, we figured it out for you in our reviews. The list of online casinos you see on this page is sorted by Global Rating. Yeah, it’s that big number you see next to each name.

Global Rating - the Fairest Casino Rating

Here’s how it works:

We look at our fellow watchdog online portals on the internet, check how they rate each particular site, add to that our own expert opinion, calculate the average, and voila - you get the most objective rating of internet casinos. Simple and ingenious, eh?

Our Opinion aka HolyMoly Score

This one is less simple but just as ingenious. In our reviews, we analyze all the important components of a casino: reputation and trustworthiness, software, bonuses, cashout time,  support, website design, and so on. We rate each component individually, then combine them into the overall score. Read more about our rating system here.

The brands you see on the top of our online casino list are as fair, safe, and reliable as they can get.

New UK Casinos

Whenever a fresh online casino licensed in the UK pops us on the internet, we immediately throw it into the ring to see how it fares against seasoned veterans. These are the websites you’ll see on the “New Casinos” list. In most cases, young companies have neither experience nor resources to impress players.

But sometimes…

Sometimes, “newer” really means “better.” In rare cases, a newcomer manages to do everything right from the very beginning. A cutting-edge website, tons of games, fair casino bonuses, gamified progression, fast and smooth payouts. It’s a real pleasure for us to review a brand-new site that can compete with (and come out on top of) huge decade-old organizations.

Casinos by Software

Here’s the deal: there are dozens of software developers who make online slots. Some of them also create full-on gaming platforms and “lend” them to casino websites to run on. We decided to keep it simple, so if you go to the NetEnt section, you’ll see the list of sites that offer NetEnt slots, not necessarily those that use the NetEnt platform.

Good news is that we have separate categories for all the most popular developers around. Open any of them, learn why this developer is cool (or not), and proceed to one of the online casinos from the list where you’ll find their games. Simple as that.

Payment Methods

When choosing a place to trust your money with, it’s crucial to pay attention to how convenient for you it would be to deposit and cash out the funds. Maybe those fancy-pancy Bitcoin casinos are just not for you, and you want to deposit with good old PayPal?

Or maybe you only have a credit card and don't want to bother creating an e-wallet account to get your payout faster?

In either case, feel free to select the relevant filter or category and enjoy the full list of UK online casino websites that allow you to cash out your winnings via the chosen payment method.

Mobile Online Casinos List 2020

An interesting fact:

Over 50% of internet traffic worldwide is generated via mobile devices.

Of course, it largely depends on the country and the sphere, but the overall trend is hard to ignore. Everyone and their mom go mobile.

What this means for the gambling niche is that a website without mobile compatibility is doomed for failure. In the Mobile Casinos section, you’ll find a list of all online casinos that allow you to play on the go on any modern device.

There’s no difference between Android and iOS devices. Whoa-whoa, wait, don’t start the holy war just yet. What we mean is that mobile online casinos run just fine on any smartphone, regardless of the operating system. The only thing you need is a fast and stable internet connection.

Game Types

When it comes to the diversity of games, most online gambling sites do fairly okay these days. They long understood that the wider the choice - the better.

Pretty much every casino on our top list has all the most popular types of games:

Slots are usually the thing in UK online casinos. So much so that you may get free spins as a cherry on top of your welcome offer. Even better - in some casinos, you can try the games for free in demo mode. It’s always a good idea to take a few practice spins on a slot you like before you bet real money.

Some websites go an extra mile and add sportsbook, poker, bingo, lottery, and other sections. If you feel like any of these is your cup of tea - select the game type in the filters and head over to the best-rated brand.

RTP Percentage

RTP means Return to Player, and it’s a percentage that shows the portion of all bets made on a particular game that is paid out back to the players over the long term.

The UK Gambling Commission requires casinos to list this rate for all titles they offer and the average payout rate for the whole site. Look it up before you register. Not only will you see if the casino is a little bit too greedy with the house edge, but also find the games with higher chances to win.

Safety and Security

Here’s a big secret:

You don’t simply trust every website on the internet.

Whenever there’s money involved, the rule gets that much more important.

In order to save yourself a great deal of trouble and have an enjoyable experience, you should only play at legit, safe, and secure casinos. Just saying, in case you were thinking, like, “Oh, what a lovely blacklisted casino, why don’t I try it out?”

First things first - all UK online casinos must have a valid license from the UKGC. Without it, they have no legal rights to accept players from the UK. Now, the license alone doesn’t guarantee that the casino management is safe, as the commission can only watch them that closely. The more reasons for you to read our reviews, where we investigate the crap out of dubious websites.

There should also be some sort of RNG certificate displayed on the website, which will prove that the software is indeed random and pays out in accordance with theoretical RTP. Such certificates are issued by third parties (iTech Labs, eCogra, or TST, just to list a few), which regularly conduct independent audits of the random number generator attached to all the games.

Other important aspects that contribute to the casino’s safety are neatly summed up in our Reputation score. We check for vague or predatory terms and conditions, player complaints that we found online, and any other traces of misbehavior. A casino denied a legit payout? Don’t worry, we’ll surely mention it in our review.

Welcome Bonuses

All online casino websites offer bonuses, with rare exceptions. Now, it doesn’t mean all of them are good or safe to claim, far from it.

The sad truth is:

Shady sites try to lure new players in with seemingly amazing offers. If there’s a banner on the website that screams “FREE £2000” in your face - chances are, you’re about to get screwed. Such “gifts” usually have a huge list of strings attached that can make you regret you had claimed it in the first place.

If you check the history of complaints about such casinos, the most of them would mention winnings confiscation and account closing, either with no explanation at all or with vague reasons like bonus abuse or not following the “spirit of the bonus,” whatever that is.

Here is one of the best T&C clauses we've ever seen while reviewing casinos. It brings a whole new level to the meaning of "bonus abuse."

“When the player got big hit he stops playing activity and requests withdraw.”

Nuff said.

Don’t lose all hope though. Great bonuses do exist.

We’ve conveniently listed them here, and you can read detailed descriptions of each welcome bonus in our reviews.

Basically, a good bonus gives you a fair chance to win and withdraw something from it.

Promotions for Returning Players

A welcome package is an excellent way to get acquainted with the casino.

What’s next though?

Not all internet casinos do this, but usually, they throw lots of stuff your way even after you’re finished with your first deposit. For one, they may send out personal bonus codes for you to claim. They are usually smaller than the welcome package, but hey, it’s still nice.

Next, there may be daily or weekly tournaments to participate in. The rules are often simple - play a particular slot, win (or wager) more than others, take the prize.

Upgrading your account is another feature that may keep you engaged. Some casinos introduce user avatars for you to level up, achievements to collect, or simply VIP tiers to climb. Casino Heroes is an excellent example of this feature done right. Read more about it in our review.

Finally, scan through the promotions list every once in a while. They are updated regularly, so you may find some new sweet offer to claim.

Responsible Gaming

Gambling is fun. When you’re in control of it that is, not the other way around.

Responsible gaming is a set of guidelines, recommendations, and policies universally employed by all internet casinos, operators, and software providers to ensure that playing remains safe and fun.

Here’s a short list of areas covered by the responsible gaming policy.

Compulsive players. If at some point you feel like you need to stop, but you can’t, it may be time to self-exclude. Contact the support operators by any means available, and tell that you’d like to delete your account. They are obliged to do so as quickly as possible or face the wrath of the UK Gambling Commission.

Underage gambling. You can only gamble if you’re over 18 years old. This is the main reason you have to undergo all those annoying verification procedures.

Anti-money laundering. Some people try to use casinos as a way to transfer funds from one account to another in order to avoid taxes or whatnot. Naturally, operators do their best to prevent such behavior. Remember those clauses in the terms and conditions that say you can only withdraw to the same credit card or e-wallet you had deposited with? There you go, now you know why all the fuss.


I’m new. How do I start playing?

Here’s a short step-by-step guide for you:

  • Choose a safe casino. Either simply take the top-rated one available in the UK from our list, or narrow down your search with our awesome filters. Read the review, see if it’s good for you, and click Play.
  • Sign up. The process takes several minutes and requires you to enter your email, name, address, and in some cases - phone number. Be sure to fill in all the data correctly, as it will be compared to your documents during the “Know Your Customer” procedure.
  • Deposit. If you have a Visa or Mastercard - you’ll be fine. Ewallets though may make the whole procedure that much faster, especially when it comes to withdrawals. You may also claim the welcome bonus when depositing for the first time. Just read the terms carefully.
  • Play. Select your favorite game and enjoy. If you claimed the welcome package, you should keep the wagering requirements and other restrictions in mind.
  • Withdraw. When you hit that big win, request a withdrawal. Again, we can’t stress enough how important it is to be informed about all the promotional terms. Make sure you cleared that welcome gift by completing the wagering requirements.
  • Check in regularly. Keep an eye on your inbox and check the list of available promotions often. You may find some sweet promo codes in there.

Can I gamble legally at any casino?

If you’re from the UK, you should only play at UKGC-licensed internet casinos. It’s safe, it’s legal, and it’s the way it should be.

Is my personal data safe in online casinos?

That depends. True and tested websites that you’ll see on our list protect your data with SSL encryption and are forbidden to disclose it to third parties, other than when required by law. Be sure to read the Privacy Policy before you sign up to learn which of your data they store and how they safeguard it.

Do I have to download the software?

In modern casinos - no, you don’t. Usually, you can play right on the website in instant play mode. In some cases, you may have to download and install the software to get access to the full library, but this gets more and more rare these days.
