Frequently Asked Questions

How do I decide which casino sites are the best?

We know time is precious and you definitely don’t have time to sift through every online casino site going, so you can find the best one. That’s why we’ve made it really easy for you to have a quick glance on our site and find the best UK online casino sites.

Our team of experts have scoured the world of online casinos, so you don’t have to. We take loads of different metrics and use them to determine ratings for games. We’ll only recommend and rate games that we’ve tested and found to be reputable and fair.

How do you rate each site?

There are lots of different things that we look at when we test online casino sites and rate games. We look at nine different details to measure sites and give you the most up-to-date, relevant info so you can choose the right one for you. And within these nine headings, there are loads more variables that we use to give even more detailed ratings.

Our reviews give you a great overview of each casino, so you don’t just have to look at the rating system – you can get lots of in-depth insight if you want to. This all helps you find the best online casino for you!

Should I only play on high-rated sites?

It’s completely up to you as to what sites you do and don’t play, but we’d recommend reading our in-depth reviews too, so you can see the reasoning behind a certain rating. Casinos can have low-ratings for all sorts of reasons, and it’s not necessarily because it’s unsafe or will compromise your privacy - every casino listed on OnlineBingo is guaranteed to be safe and secure.

Instead, a casino can have a low rating for various reasons, perhaps because it’s not as modern or entertaining as we expect nowadays. It might have poor user design or customer service but that doesn’t mean that you don’t have a good chance of winning prizes. It depends on your own personal preferences.

What should I look for in a casino site?

When you’re thinking about playing at an online casino site, looking at reviews and what other players are saying is a really useful way to get the lowdown on what the game involves and your chances of success. We’ve made it easy with our rating and review system, so you can get an expert opinion in seconds.

Ultimately, it’s up to you to decide what is most important to you - are you interested in bonuses, game variety or something else? Whatever you're into though, we always recommend you take a quick look at the site’s T&Cs and rules before you play to fidn the best online casino and see that it suits you.

Are your casino reviews reliable?

We only endorse and work with the best online casinos that have passed certain safety and security tests, so that we only promote credible sources.

Our reviewers are casino experts with years of experience, and our review format ensures players receive honest, trustworthy information that accurately captures how a casino works and plays. Plus, we also make it easy for players to leave reviews on a site page - be sure to check those out if you need a second opinion!

And of course, once you've visited a site and tried it out, be sure to return to OnlineBingo and leave a user review for others!

What are the best bonuses at casino sites?

It completely depends on your preferences, but lots of the top online casinos offer introductory bonus offers to hook you in and get you playing. This can be a really good way to get started, and give you a tempting incentive to join and play.

You can access first deposit bonuses, welcome bonuses and no deposit casino bonuses at various sites, and they all help to add an extra incentive to your hunt for a new site. Plus, enhanced bonus offers at sites may lead you to trying a casino you would never normally play at!

Intro
What makes a casino site good?
Why casino reviews matter
Best Online Casinos this month

There are hundreds of online casino sites, and the explosion of mobile usage has helped open the industry to millions of players. Gone are the days where players had to visit a land-based casino or dingy arcade to play their favourite game - all the best casino and slot games are available wherever and whenever the player wants them.

That being said, with hundreds to choose from, how do you get started with the online casino world?

What makes a casino site good?

We assess online casinos in nine different areas, and every site listed on this page goes through this tough, rigorous review process. We can then sort our online casino listings, and highlight the ones that are most worthy of your time. Some sites don't get through our process at all, especially if they fail any of our safety or privacy standards - our listings ensure privacy and safety.

There are lots of variables that we look at, such as: how effective the customer support on offer is; whether there is a good selection of bonuses available; whether it has exclusive features for you to enjoy; how compatible the casino is with different mobile devices; and whether your data is kept safe and secure.

Of course, we also look at whether the site is fun, entertaining and offers you decent rewards too!

Why casino reviews matter

Our team of experts regularly review and test casino sites, allowing us to provide extra information and give you the best idea possible about which casinos are worth a dabble. We approach each site fairly, and give it an honest appraisal, unlike most other casino portals out there.

All hail the reviewers

Thankfully, there are a dedicated team of reviewers who go through hundreds of sites to help find the best ones for you to play at. There might be casino sites that lure you in with loud, outrageous offers, but our team looks past the noise and measure sites on their actual value, rather than what can be seen with one quick glance.

You can check how up-to-date our reviews are, which is important because there are so many sites out there with reviews and ratings which might not be relevant anymore.

Always try before you buy

Although we think it’s great that you’ll use our rating systems and in-depth reviews to decide where you want to play, we always advise thoroughly researching them yourself. If you can claim a no deposit bonus before you commit funds, it’s a good way of testing the site out and seeing if it is right for you.

We also recommend always reading the terms and conditions anywhere you go, as some casino games and sites might have specific regulations that differ to other sites. There can be varied wagering and withdrawal restrictions, so be sure to check those thoroughly. Even if a game has an attractive looking welcome offer, it could be tied to a condition that makes it difficult to make a withdrawal or lock you into something you didn’t understand - we will highlight these issues, but always always always double check for yourself!

Best Online Casinos - 2021

New casino sites pop up on a constant basis, but there will always be popular, high-performing casinos that consistently resonate with our audience and come up trumps in our testing. You can also browse our complete listing of slot sites for some extra variety.

32Red Casino – 96%

32Red Casino has got a whopping rating of 96% which makes it one of our top rated casino sites right now. It was launched in 2002 and has won loads of awards since then with its responsive design and well-laid out game-style.

LeoVegas Casino – 93%

LeoVegas is a relatively new casino site, launching in 2012, but it’s managed to make its mark and position itself as one of our best-rated casino sites – it also has an awesome name, who doesn’t love lions?

It has a first deposit bonus of 100% and a minimum deposit amount of £10 to get you started.

What are the similarities between high-rated sites?

So what can we learn from high-performing sites and the best-reviewed sites? Looking at the three casinos mentioned above, you can see that there are a few factors that these sites manage to nail.

Customer service is taken really seriously by all of these sites - they offer comprehensive, easily accessible support 24/7 through live chat, email and call centres. Investing in customer support helps to keep players happy and safe online, and it's a clear sign that the casino values player experience.
The usability and design of these sites make it really easy for beginners to enter a site, quickly find out what to do and where to go.
These sites offer healthy promotional offers and a range of bonus features. It’s worth reading up on each but with these 3 sites in particular, there are great incentives for all players and exclusive casino promotions that can't be found anywhere else.
