Our List of Top Online Casinos

You can easily spend countless hours looking at different online casino sites, reading reviews and comparing what different casinos have to offer. You may well find great online casino sites to play at that way, but spending so much time researching casinos can be quite tedious. That’s why we’ve done the research for you and come up with our list of the best online casinos!

The casinos on our list are ones we ourselves would sign up to. Every casino we’ve listed ticks plenty of boxes and is generally very well received by online players. You can rest assured that if you register with any of these casinos, you’re sure to have a brilliant online gambling experience.

Which Casinos Make the Cut?

So how do we go about deciding what the best-ranked online casinos are? There’s a lot that goes into our decision-making process. After all, making sure that only the very best gambling platforms are presented to you is our core focus. Based on our trust range system, we look at lots of different criteria and see how a casino stacks up. The casinos that we recommend are the ones that do very well in pretty much all of our trust range criteria, which include Licensing, Bonus & T&Cs, Games Selection, Banking options, Mobile Support, Customer Support and so on.

There are also some casinos that, for one reason or another, just aren’t that good. But don’t worry, you will find none of those here.

Gambling License Holder

First of all, we double-check to make a casino’s fully licensed and is as safe and secure as can be. We would never want to point you in the direction of a casino that can’t be trusted. There are numerous regulatory authorities around the world that hand out gambling licenses to online casino operators. These include the Malta Gaming Authority, the UK Gambling Commission, the Government of Curacao and the Alderney Gambling Control Commission.

If a casino has a license, this is a sign it’s been checked over and given the go-ahead to operate. Organizations won’t provide a casino with a license if they think it’s unsafe or unreliable. All the casinos on our list have a license – some may even have more than one if they’re available in lots of countries.

You should find the license on a casino’s main page. Simply scroll down towards the bottom of the page and it should be there. If you can’t find it anywhere, it’s a good idea not to sign up, just to be on the safe side. When playing online, you want to be safe and sound, so that’s why you should only play at casinos with licenses.

Gaming Selection

Once we’ve checked a casino has a license and is trustworthy, then we look at what it has to offer in terms of online casino games. Any good casino should have hundreds of online slots – if not over a thousand – along with a huge range of table games, live casino games and other games, such as video poker, bingo, keno, scratch cards and virtual sports. Basically, the larger and more diverse a casino’s game selection is, the better.
Ideally, a casino’s range of games should come from a selection of leading providers. Some of the top ones include Microgaming, Play’n Go, NetEnt, NextGen Gaming, Playtech, Yggdrasil and Pragmatic Play, to name just a few. There are nearly +250 providers altogether and many of them are highly regarded, even the ones that have only been around for a few years.

Online casino games should be well organised. There will usually be several categories for different game types (slots, table games, live dealer games, etc.), along with categories for the casino’s newest and most popular games. For casinos with a wide variety of game genres, it helps to have filters available so you can search through the collection and find what you’re looking for more easily.

Since there are constantly new games coming out, it’s great if a casino adds to its games collection frequently. There shouldn’t just be a set number of games – a casino should expand its collection whenever it can.

Promotions and Welcome Bonus

Don’t you just love having bonuses to claim? We do too and that’s why we only recommend casinos that have a wide range of bonus offers available. Any good casino should have a generous welcome offer for new players, along with lots of other special offers you can claim. The line-up of casino bonus offers will change regularly since some offers will only be around for a short amount of time. As long as there’s always at least a few promotions, you can take part in, that’s good with us and that’s what we think makes the online casino experience!

Some of the rewards UK players can receive from promotions include bonus money, free spins and cashback. Some casinos may even hold tournaments with cash prizes and offer things like gifts and invitations to real-life events. You can only use free spins on slots – sometimes, you can only use them on select slots. As for bonus money, you can use it on most, if not all, of a casino’s games.

You can also claim bonuses from a casino’s loyalty scheme and VIP club. A loyalty scheme typically has several tiers. The more you play at the casino, the more points you’ll earn and the higher your tier. As you work your way up the tiers, you’ll receive bigger and better bonuses. As for the VIP club, if a casino has one it’s usually invite-only. To qualify for an invitation, you have to be a very loyal player indeed. In other words, you have to frequently spend quite large amounts of money playing the casino’s games. If you become a VIP, you’ll benefit from all sorts of exclusive promotions, bonuses, rewards and more. Don’t forget though to read the bonus terms of each casino so you know if the bonus applies to only your 1st deposit, how much real money you need to spend before you can withdraw your winnings, also unused bonus funds might expire as well so be aware of this when depositing. Sometimes bonuses are locked to a selection of games but more than likely they will be popular casino games so you should be on the online casino sites.

Banking Options (Deposit & Withdrawal)

When it comes to banking, we like it when a casino accepts lots of payment methods. Practically every online casino will accept deposit types such as  Visa and MasterCard, while other common payment options include e-wallets, prepaid cards and bank transfers. A growing number of online casinos even accept cryptocurrencies! Ideally, there shouldn’t be any extra charges for using any particular payment method. However, in the United Kingdom, you are no longer allowed to use credit cards at online casino sites.

We really like to see fast withdrawal times. Whenever you make a withdrawal, it can take a casino anything from less than a day to two or three working days to process your request. The less time it takes, the better. Once the casino has processed your request, it then takes an extra amount of time for your money to reach you – this depends on the payment method you’re using. For e-wallets, you should receive your money as soon as the casino has processed your withdrawal request. For other types of payment methods, you should have to wait a few working days or more.

Design and Layout

Online casinos should look good. They should look good enough that you’ll want to sign up and play. The very best casinos will go the extra mile and will have lots of theming to set them apart from others. Casinos that have themes can offer a more immersive and enjoyable experience, especially when the theming’s of a high standard. Some casinos even create their own characters who you’ll see on some of the different web pages.

As for the layout, the more straightforward it is, the better. Many online casinos have a lot going on, so it helps to keep things tidy and clean. Having a straightforward layout makes casinos more easily accessible, especially for those who are new to online gambling.

Mobile Compatibility

These days, the vast majority of online casinos have a mobile version. To access a casino’s mobile site, simply visit the casino through the web browser on your device. Whether it’s a smartphone or a tablet, you should be able to access the mobile casino easily enough. Mobile casinos are simply mobile-friendly versions of the main desktop casino. They typically come with everything you’ll find at the desktop casino, though there’s a chance, not every game will be available. This is because some providers haven’t yet created mobile versions of all their games. Still, the typical mobile casino should have at least a few hundred games available to play.

Many online casinos also have an app you can download on to your device. Most of the time, apps are only compatible with iOS or Android devices. You can download casino apps from the App Store on iOS devices or from Google Play on Android devices. Apps may sometimes have fewer games than mobile casinos, but the games tend to have better performance quality.

Customer Support

If you’re playing at a really good casino, you shouldn’t have to contact customer support too often. All casinos should have a good customer support system in place for if you ever need to get in touch. Ideally, a casino will offer several ways of getting in touch, including a phone number, an email address and a live chat feature. At some casinos, there are a few hours of the day when customer support isn’t available. What impresses us is when you get in touch 24/7. If a casino offers round-the-clock customer support, you shouldn’t have to wait too long for replies when sending an email.

So to sum up, any casino that we’re happy to recommend does well in each of the criteria above. A good casino is safe to play at and user-friendly, with more than enough games to cater for players of all tastes. It also has lots of rewarding bonuses, good customer service and a reliable banking system with fast withdrawals. Finally, a casino should look good and finding your way around should be simple and straightforward. If a casino ticks all these boxes, there’s a good chance we’ll recommend it!

Being Responsible

For most people, gambling is simply a hobby they enjoy once in a while. However, some people do become addicted to gambling. Any good casino will offer lots of resources to help those who either have a gambling problem or are developing a gambling problem. Information about gambling addiction should be available, as should links to gambling addiction to charities and limits on your account. A casino should let you limit how much you can deposit, win and withdraw; the option to self-exclude temporarily or permanently should also be available.

Our Reviews
