Below is a summary of our expert's top 10 UK casino sites, with an explanation as to why each of these sites has made the list. 

Top 10 UK Casino Sites According to OLBG Casino Experts 

1. Duelz Casino 

When we have questioned users about what they want from a casino, it's often not the game choice or the look of the site, but how quickly they can withdraw their winnings. Duelz has an average payout time of 6 minutes from request to the money landing in your account. And to most casino players, that's priceless.

The great thing is, Duelz also back this up with a huge games library, whether that be live table games or slots from the biggest slot studios

2. BetMGM Casino

We know how much hassle the account verification is for players and how frustrating the document uploads can be - we get so many comments in user reviews about this. Step forward BetMGM with one of the easiest sign up processes and KYC options which can have you up and running in moments, without account blockages. 

Throw into the mix a fantastic selection of slot games, table games and live studio stuff like Crazy Time, and they've pretty much got everything you need including ongoing promotions every week.

3. 32Red Casino

Having played so many games at casinos over the years, and specifically looking for new releases, finding a casino that has exclusive games is always cool. 32Red have exclusive versions of games you won't find anywhere else as well as early releases, which is something I go for. 

With tons of jackpot slots to choose from as well, there is more than enough variety before we get into the huge table game and live dealer library on offer. Regular promotions keep you engaged

4. Unibet Casino

Unibet was not top of the teams selection but for me personally, they sit a very close second. I like the way my games are easy to find, again, exclusive releases from studios that you can only play at Unibet for a couple of weeks before general release. 

Also, if you are like me, you like your withdrawals back in your account quickly. Unibet never let me down in that regard, although, if you are lucky to need a ‘big’ withdrawal there may be a 24 hour wait. But once document upload and verification is complete, everything is a breeze.

5. Neptune Play Casino

So we come to my personal favourite online casino for slots at least. What I like about Neptune is that they try to deliver exactly what the player wants. Highlighting new released games where you want to see them, and through your play, they understand your favourites and titles you may like that are similar or from the same providers. 

Those quick payouts of your withdrawal requests again help score them highly and there are always promotions on the go, and tournaments to join in with.

6. Midnite Casino

I’ve been a big fan of Midnite since they arrived on the scene and the team here at OLBG agree in general. Very much like Neptune, they have a simple interface, making finding the games you want to play nice and easy, providing ‘top picks for you’ based on your play history.

I particularly love the fact you can create a favourites tab on the menu and the rewards section where you can you can find your free spins, vouchers and credits

7. Pub Casino

One of the best things about Pub casino is the branding - very clever. Pub have recently updated the site and it looks realy cool.

One of the best things about Pub casino is the Live Dealer section. This is separated from the main noise on the site, where you can browse a huge range of live dealer games, running through the usual blackjack and roulette through to live poker too.

8. All British Casino

All British Casino is all about the cashback for me. Always on 10% cashback on your deposits is something I've not seen elsewhere, and can mount up over time. We really like the live casino here too, they push it quite heavily, but it is good. Thousands of slots to choose from. We didn't think the way they are displayed is the best but you can search by game title if you know what you are looking for.

9. Spinyoo casino

The team have pulled SpinYoo casino into our top ten casino sites off of the back of several aspects, not least of which is the welcome offer. Coupled with the loyalty program and regular promotions, Spinyoo really do offer a place for regular players to feel valued - We don't ask for much more than that.

That's not to say everything you need isn't there, a wide range of live casino options and plenty of slot games too, SpinYoo makes a confident choice in our top ten.

10. Buzz Casino

Buzz casino are brilliant for jackpot games, they've a huge number of them, so if you are a jackpot hunter, they are very much recommended. On the other hand if you play Blackjack online then Buzz Casino has one of the best range of games to choose from. Dozens upon dozens of live dealer games, or RNG blackjack options to choose from.

We really like the simple sign up process to, that is one thing that really makes it an easy choice
