1. PlayOJO – Most Popular Online Casino in the UK Overall

Glasgow Times:

18+. New, ID-verified players only. Extra bingo tickets worth 10p. Bonus spins on Big Bass Bonanza worth 10p each. No wagering requirements. Note that the full T&Cs apply.


  • High ratings on App Store and Google Play
  • 3,000+ casino games
  • Grab 50 casino bonus spins
  • No bonus wagering requirements
  • Extra, ongoing ‘Kickers’ promos
  • Award-winning site
  • Can withdraw as little as £1


  • No specific matched deposit bonus
  • Relatively fewer payment methods

When it comes to trusted UK casinos, there’s no better option overall than PlayOJO. This site is the real deal!

UK Casino Games: 5/5

We’re pretty confident that the overall casino game selection at PlayOJO is unmatched in the UK right now.

This reputable online casino UK site is offering over 3000 games in total, and the vast majority of them are very, very good.

We can tell this by the fact that the list of software providers who chipped in is pretty much faultless.

It contains all the most prominent names, like Blueprint Gaming and NetEnt, on slots duties. Plus, you’ll be treated to some incredible live casino games from Evolution Gaming.

Bonus Offers: 4.95/5

If you don’t have a PlayOJO account already, you can get an impressive 50 bonus spins with no wagering requirements at all when you sign up for one and put down a deposit of just £10.

The lack of wagering requirements means that anything you win with the spins can be instantly withdrawn! There’s no doubt that a lot of people are going to prefer the sound of that to a matched deposit with a high playthrough requirement.

There are a handful of extra promotions at PlayOJO to take part in once you’re finished with these, which can be found in the Kickers section. These change each day, so keep an eye on them.

Misc: 4.9/5

The PlayOJO mobile app is one of the most highly rated casino apps on both the App Store and the Play Store in the UK. That makes a lot of sense, as it’s a real treat to use both in terms of how attractive the interface is and how many games it features.

A minor downside is that there are fewer payment methods offered. However, the popular banking options are covered, so we’re happy with the banking side of things here, as all payouts are processed in just a few hours.

Popularity: 4.95/5

Despite only being founded in 2017, PlayOJO is one of the most trusted online casinos and has won many prestigious awards, including ‘Best Slots Site 2021’, ‘Best New Bingo Site 2021’ and ‘EGR Mobile Casino of the Year 2023’.

That says a lot about how high quality this site is and how popular it is amongst players.

2. Luckland – Most Popular Online Casino in the UK for High RTP Games

Glasgow Times:

18+. New, ID verified players only. Minimum deposit £20. 40x wagering requirements apply. Wagering contributions vary. 50 spins on Starburst. Note that full T&Cs apply.


  • Almost 10 years in the game
  • Plenty of High-RTP casino games
  • Over 1,200 slots
  • £50 and 50 spins for new players
  • Up to 50 daily bonus spins


  • Dated app design
  • Could feature more game categories

An excellent welcome bonus can really go a long way, and that’s undoubtedly true of Luckland. Plus, you’ll find many high RTP slots at this legit UK casino site.

UK Casino Games: 4.95/5

The total number of online casino games at Luckland right now is well over 1300, another impressive figure.

The majority of these are slots from the likes of Pragmatic Play and Play ‘n GO, so not only are you going to see a lot of fun titles but plenty of jackpot networks as well, including Drops & Wins.

There’s also an impressive list of high RTP games, such as Evolution Gaming’s Live Roulette, with an RTP of 99%, and other slots with RTP scores exceeding 96%.

Speaking of live casino games, another impressive area of the Luckland game selection is the live dealer section, which features dozens of options. Many of these have been developed by Evolution Gaming, too, so there’s a lot to be said about the quality of that department.

Bonus Offers: 4.95/5

The incredible welcome bonus in question at Luckland is a 100% matched deposit of up to £50, plus 50 bonus spins for the iconic slot game Starburst. We love a double-loaded welcome bonus like this, as it’s a lot more fun to have both the matched deposit and the extra spins.

On top of that, all players will have the chance to grab up to 50 bonus spins every single day through the Daily Spin Frenzy offer.

Misc: 4.9/5 

This trusted online casino site is also very quick to payout, with most withdrawals processed in just a few hours. Moreover, there are nine payment methods here, which is excellent for flexibility.

A few options include MuchBetter, Skrill and AstroPay.

The mobile app is downloadable and packed with games, but both it and the desktop site feel a little dated. Plus, it can be confusing to navigate for games as there aren’t enough categories, but that’s only a small niggle.

Popularity: 4.9/5

Formed in 2015, this reputable online casino has had almost 10 years to make a name for itself and it’s made the most out of that time.

The fact that there are so many positive reviews about it online shows us that it’s clearly still one of the favoured online casinos for popularity.

3. All British – Best Welcome Bonus of All Popular UK Online Casinos

Glasgow Times:

18+. New, ID Verified players only. Up to £100 bonus credit. Min deposit £20. No max cash out. Skrill and Neteller deposits excluded. 35x wagering requirement. Note that full T&Cs apply.


  • 55+ amazing live casino games
  • Up to £100 for new players
  • Score 10% cashback
  • Elite list of software providers
  • Smooth mobile interface


  • Fewer jackpot games
  • Skrill & Neteller deposits excluded from bonuses

If you want to combine the social element of brick-and-mortar casinos with all the added perks of exciting casino bonuses, then check out All British.

UK Casino Games: 4.8/5

There are 55+ live dealer games to play at All British, a figure that’s actually lower than some of our other picks. However, the level of quality and the array of games here are what sets All British apart for its live dealer action.

Most of the games come from Evolution Gaming, which tells you everything you need to know about the quality of them.

And unlike most live casino game catalogues, blackjack and roulette don’t dominate (although there are still plenty of options for each).

This means you’ll find tons of unique options at this trusted online casino UK site, like Gonzo’s Treasure Map and Extra Chilli Epic Spins.

The live casino is elevated further when played through the downloadable desktop or mobile All British apps. The software helps to load the games more quickly and is generally more enjoyable to use in terms of the overall layout and design.

You can also use the apps to play the impressive range of slots and non-live casino games, by the way!

Bonus Offers: 4.95/5

The current new customer offer at All British is a massive 100% matched deposit of up to £100. This is one of the largest welcome bonus offers we’ve ever seen in the UK!

You’ll also get 10% cashback, which is impressive, although there aren’t any bonus spins to be grabbed at the time of writing.

Misc: 4.85/5

You’ll be able to choose from nine payment methods at All British, with Neteller, Trustly and Apple Pay all on the cards.

Payouts are fast, too, as they’ll never take any longer than 24 hours. However, you will have to put up with a £5000 daily withdrawal limit, which might make things a little awkward if you land a big win!

Furthermore, if you don’t download the All British apps, you might find that the regular desktop and mobile sites are a little confusing to navigate as the layout and colour scheme aren’t quite as clear.

Popularity: 4.85/5

This reputable online casino in the UK has just passed its 10th birthday, so it’s safe to say that it’s an ornamental part of the online casino industry in the UK.

The positive reviews of the mobile app in the App Store and the Play Store, as well as plenty of praise on online message boards, reaffirm that notion.

4. Slots Magic – Most Trusted UK Casino Site for Slots

Glasgow Times:

18+. New, ID verified players only. Minimum deposit £10. 30x matched deposit wagering requirements apply. 60x bonus spins wagering requirements apply. Max bet £5. Bonus spins are worth £0.10. Note that full T&Cs apply.


  • Around 3,000 slot games
  • Casinomeister accreditation
  • 100% bonus up to £50
  • 50 bonus spins
  • Seven-figure progressives
  • Exciting casino tournaments


  • Bonus cashout limits apply
  • Customer support not available 24/7

You’d have hoped that an online casino that names itself after slots would have a lot of them. Fortunately, Slots Magic delivers in that regard and then some.

UK Casino Games: 4.85/5

With around 3,000 online slots to choose from, it’s clear that Slots Magic is one of the most packed online casinos. You’ll be able to play titles in all different forms, including huge progressive jackpots, games with exciting themes, loads of bonus spin rounds, etc.

Part of the reason for this diversity is the impressive list of software providers that have contributed to the catalogue.

We found plenty of titles from iSoftBet, Play ‘n GO and some of the other biggest names in the business, which is certainly a sign of the quality of the games.

Bonus Offers: 4.8/5

The current slots magic welcome bonus is a very impressive 100% matched deposit up to £50 with 50 bonus spins thrown in for the Rich Wilde and the Book of Dead slot.

This is, of course, a very similar welcome bonus to the Luckland offering.

In fact, the matched deposit wagering requirements are lower, but you will need to play through the bonus spins a few more times.

Misc: 4.75/5

There is an actual mobile app to download for Slots Magic but it could use some work. The scores are a little low in the App Store and the Play Store, with users reporting slow loading times and glitches.

Nonetheless, it is updated often in both app stores and features most of the slots, so it’s still worth getting!

The banking side of things at Slots Magic is fair, too. They impose a 24-hour pending period on payouts, so things won’t happen as quickly as at our top three, but that’s still faster than average.

Popularity: 4.8/5

Slots Magic might not be as well known as the three above it, despite being in existence for 10+ years.

However, it does have a lot of accreditations from the likes of Casinomeister, and this certainly adds to its safety, which, in turn, has caused it to become a pretty popular casino overall.

5. Red Kings – Most Popular UK Online Casino for Live Games

  • Grab 100 bonus spins
  • Convenient payment methods

  • 100+ live dealer options
  • Helpful FAQ section on site


  • Mobile compatibility is limited
  • Lacks a match deposit offer

Red Kings was first formed as a casino all the way back in 2006. So, it’s had 18+ years to build up its reputation and has done so in fine style. Plus, you’ll have access to over 100 live dealer gaming options here.

UK Casino Games: 4.8/5

You’ll find around 3,000 total games to play at Red Kings, which is an impressive haul indeed. But just as impressive is the curation itself, having been delivered by some of the top developers in the world.

Red Kings has clearly spent a lot of time throughout its near-20-year reign to do business with hit providers, as it now boasts games from the likes of ELK Studios, Blueprint Gaming and NetEnt.

This means you’ll find all the classic slots, online poker, live casino games and more. Not only that, but they’re also constantly adding all the hit new games, so you’ll never have to miss out on the latest action.

Bonus Offers: 4.75/5

When you put down your first deposit of £10 or more at Red Kings, you’ll get 100 bonus spins for the Sahara Riches Cash Collect slot credited straight to your account.

Even without a matched deposit bonus, it’s still a good offer overall, as is the VIP Club, where players can get extra perks as they rise through the ranks the more they play on the site.

Misc: 4.75/5

Red Kings offers a seamless mobile gaming experience, with its games optimised for any mobile browser, establishing it as one of the premier UK phone casino destinations.

Additionally, there are several convenient banking options here, including Apple Pay and PayPal, plus payouts only take around 20 hours, which isn’t too bad.

If you run into any problems, you can always speak to the helpful support team.

Popularity: 4.75/5

The 18 years of experience behind Red Kings has allowed it to cement its position as one of the best UK online casinos.

The site has managed to stay relevant for all these years thanks to its high-quality content and high levels of safety.

How We Ranked the Most Reputable Online Casinos in the UK

UK Casino Games

Probably the most important factor of online casinos for most players is the choice of games.

Everyone has different preferences, and the most reputable UK online casino sites featured here cater to a wide range of tastes with their game curations.

Bonus Offers

It’s crucial that reputable casino sites all offer a welcome bonus, which could be bonus spins, matched deposits or both.

But it’s just as crucial that the terms and conditions for these bonuses are fair, i.e., wagering requirements and time limits.


This category rounds up all the other important things that go into what it is to be a quality online casino site in the UK.

We’re talking about mobile compatibility, payout speed, banking options, customer support, etc.


The more popular an online casino is, the more likely it is to be high quality and safe.

To figure this out, we’ve been reading reviews from other players, considering how long the casinos have been in business and researching any awards they might have won.

Are Popular UK Online Casinos Safe?

Yes, popular UK online casinos are safe as long as they are licensed and regulated by the proper authorities.

In fact, the more popular an online casino is, the more likely it’s going to be safe. The most highly trafficked UK online casinos owe a lot of their popularity to the fact that they’re reliable and secure, as word gets around easily in the online casino community!

If an online casino was ever found to be practising in a way that wasn’t safe, the news would quickly spread, and the site would swiftly lose its popularity. That’s the beauty of it!

All of the trusted online casinos we’ve picked out today have been validated for safety, too. We used a set of specific criteria to put each of them to the test, and if they’d failed on any hurdle, they wouldn’t have ended up in our rankings.

How Can You Tell if a UK Gambling Site Is Legit?

There are plenty of ways to tell if a UK gambling site is legit.

You can put online casinos to the test yourself if you so wish. Here are a few of the factors to check:

  • Player Reviews: The best people to get an honest opinion about the safety of UK online casino sites are the players themselves. Check out online message boards to find out if any particular online casinos treat players safely.
  • Customer Support: An online casino is only ever as good as the customer support it has to offer. In fact, many UK casinos will always provide a responsive live chat for most of the hours of the day, if not all of them.
  • Payout Speed: The faster an online casino pays out, the more likely it is to be trustworthy in our experience. It always feels like a bad sign if a site makes players wait for ages before delivering winnings.
  • High RTP games: If an online casino is packed with high payout games, it’s clear to see that they value fairness to players. This is, of course, excellent news for safety.

Furthermore, you can always check that a casino is licensed correctly through the UK Gambling Commission.

The role of the UK Gambling Commission is to ensure that each UK casino site is operating safely, so it’s a seal of approval if they’ve passed the UKGC test.

Can You Wager Real Money at Trusted UK Online Casinos?

Yes! All of the reputable online casinos these days allow UK players to wager with real money, and you could be in with a chance of winning real money if luck is on your side!

There are a few factors to consider when playing for real money, of course. Here are some things to think about when you’re looking at real money casino site options:

  • Payment Methods: Any online casino will let you pay with a VISA or Mastercard, but you might want to try an eWallet or a voucher. If that’s the case, make sure to look at the payment methods supported by each site before you sign up.
  • Payout Speed: Reputable online casinos should process payouts in no more than around 24 hours or a few days at most. If they make you wait weeks for your payments, then it could be a sign that they’re not quite so trustworthy.
  • Max Withdrawals: Players who consider themselves to be high rollers might want to think about the max payouts from casinos. If you win big money, it might be awkward to have to split your withdrawals across a few payouts instead of receiving them in one go.
  • Deposit Limits: If you don’t want to play casino games super seriously and would rather play for a smaller amount of cash, consider the minimum deposit for the casinos you’re looking at. Some will let you get started from as little as £5.

However, the most important tip of all is to remember that online casino gaming should never be looked at as a money-making mission. It’s meant to be about fun, and there’s never a guarantee of profit, so make sure to practise responsible gambling at all times.

Which Popular Games Can You Play at Online Casinos in the UK?

Not sure what to play once you sign up for your new account at a popular online casino? Here are a few of the most popular online casino games to give you some inspiration.

  • Slots: You’ll find the UK’s favourite online casino game at pretty much every popular site in the country. Casinos offer a wide range of quality slots, too, with progressive jackpots, exciting themes and more.
  • Roulette: Once upon a time, roulette was considered to be a nobleman’s game that only the high society would be able to enjoy. Nowadays, it’s one of the most popular online casino games thanks to its exciting gameplay and potential for very fair payouts.
  • Blackjack: Another classic casino game that also pays out very fairly is the classic card game of 21. It’s easy, fast and widely available at trusted online casinos in both its live and non-live forms.
  • Bingo: It might not be as popular around the world but bingo is undoubtedly one of the UK’s favourite casino games. Some sites, such as PlayOJO, offer dozens of different bingo rooms to get involved with and sometimes even specific bingo bonuses.

Which UK Casino Games Have High Payouts?

If you’re looking for UK casino games with high payout rates, consider trying out the following options:

  • Pragmatic Play Live Roulette (99.5% RTP): This gorgeous live dealer game from Pragmatic Play boasts beautiful graphics, professional live dealers and a near-100% RTP that gives players every bit of chance of winning.
  • Evolution Live Blackjack (99% RTP): In a very close second place, Evolution Gaming’s Live Blackjack is one of the most popular casino games in the world, and its potential for fantastic payouts is a key reason for that. You can try this game at PlayOJO.
  • Mystery Reels Megaways (98.06% RTP): Who said slots have to have lower RTP rates? This awesome title pays out very fairly and is packed with in-game bonuses as well as some 117,649 ways to win courtesy of the Megaways engine.

So, Pragmatic Play’s Live Roulette game has arguably the highest RTP of any online casino game out there. This fair payout rate is a real treat to players, and the gameplay itself is fantastic, so for us, it’s kind of a no-brainer.

Tips and Tricks for Playing at Popular UK Casino Sites

Always Learn the Game Rules

Make sure to find out exactly what you need to do to win a casino game before you start to play it, in terms of the game rules, slot paylines, etc.

If you’re ever unsure, you can often play the games for free in demo mode to get some practice before you start spending your money.

Find Out the House Edge for Each Casino Game

The house edge of a game negatively corresponds to the RTP. So, you’ll want to look for games with RTPs of 95% or higher generally when playing at an online casino UK site. And that would work out to a house edge of 5% or less.

Look for Lower Payouts in Jackpot Slots

The lower the jackpot, the more likely you are to win, as there will be less competition from other players.

And it’s hardly like you need to compromise a lot in order to follow this tip, as even some of the lower progressive jackpots out there are offering life-changing amounts of money.

Consider the Bonus Terms and Conditions

Always read the terms for each bonus to find out any game restrictions, wagering requirements, time limits and more. If you end up missing something, you might end up invalidating the bonus and losing any winnings you might have landed.

Make the Most of Several Deposit Bonuses

Most trusted online casinos will offer a welcome bonus to all new players, and there are a lot of them out there as a result. Why not try out a whole bunch of them and cash in on some extra spins or deposit bonuses while you shop around for a new casino to call home?

Always Practise Responsible Gambling

The most important tip of all is to be responsible with your gambling.

Check out responsible gambling tools such as deposit limits and time check-ins to help you stay in control of your habits and manage your spending.

So, What Are the Most Reputable UK Online Casinos?

At this point, we think it’s pretty fair to say that the trusted online casinos we’ve picked out today are more than deserving of their popularity and are worth checking out. They treat players very fairly, are packed with games, and offer generous bonuses to new customers.

PlayOJO does all that better than the competition and even goes the extra mile by offering a top-quality mobile app, supplying responsive customer support and paying out withdrawals quickly. That’s why we’re confident it’s the first site casino players in the UK should check out.

They’re offering a great welcome bonus for new players as well, but they’re hardly the only online casino UK site from our top 10 to extend that courtesy.

So, take some time to explore the sites to work out which are best for you and grab some fantastic offers as you do so. Have fun, but always remember to gamble responsibly.
