What to look for when searching for the best online casinos

Naturally, there are plenty of different factors that need to be taken into consideration when compiling a top ten list. There are a lot of other sites out there that have their own set of criteria, but here at Gambling Metropolis, we opted for a deep dig so that our players would only see sites that truly tick all boxes and offer the greatest value proposition.

Those that are newcomers to this industry and hit on this article first – well done! You’ve hit the jackpot, and most likely have just saved yourself a lot of time searching for great deals and figuring out all the different elements that make the best casinos great and the less worthy contenders mediocre.

You can trust that we’ve done our homework and that each site was thoroughly tested against the criteria that we believe is worth judging. In order to stand out from the crowd, at Gambling Metropolis, we believe that top rated online casinos must prove their worth in each of the following areas:

  • Safety and security
  • Fast payouts
  • Customer support
  • Game selection
  • Established game providers
  • Licence and regulation
  • Mobile capabilities
  • Deposit methods
  • Payout Percentages

As you can see, we really left no stone unturned in determining what makes the sites above worthy of a place on our shortlist. But, in basic terms, the best casino sites all have a few things in common and one key element right every time. They tend to favour a clean, simple design that makes it easy for even new users to get to grips with.

Think about it, do you really want to waste some of your free time trying to figure out how to navigate a gaming site? No! You’re there to play and sites that make it easy to browse their games and that offer a smooth gaming experience will inevitably stand out from the crowd and prompt their players to come back to play again.

Bad casinos often fail on making a good first impression in this regard, but when their licenses and credentials also fall short, then no amount of promissory welcome bonuses or payout percentages will make up for such major flaws.

How we Review the Top UK Casinos:

At Gambling Metropolis, we appreciate that our users come from a variety of different levels of experience, but regardless, it is always important to know what the criteria we use to put our list together actually means, and why it is so important for you.

So, here’s a brief overview of each of the aforementioned areas that we judged the sites that made our list against before they were named among the top online casinos in the UK.

Safety and Security

Trust is everything when it comes to online gambling. Our goal was to highlight only those sites that have solid standards in place to protect you, first and foremost. Secondly, since a lot of money is involved on any given day, the security standards of the site must be ironclad, which means a secure website and software backed by encryption.

Deposit Methods

If a site does not offer the most popular payment choices, such as Visa, MasterCard and PayPal, as well as many others then the chances are that a certain number of users will feel inconvenienced, which is a major negative.

Customer Support

The strength of a site’s customer support will go a long way in terms of deciding whether you will continue playing or return. Furthermore, it should be easy to get in touch as and when you need to, and the team serving you should be knowledgeable and capable of sorting whatever issues you have quickly.

Licence and Regulations

One of the first things that we checked at Gambling Metropolis when we set out to determine our list of the best online casinos in the UK today are the licenses that each site have, and that they are regulated by the appropriate governing body. The absence of even a single licence is bad news but where there is a lack of evidence that the UK Gambling Commission or the Malta Gaming Authority properly regulates the site, you can bet that we won’t even consider it for the long list let never mind the short list.

Welcome Bonuses

We take a close look at the different kinds of casino welcome bonuses that are offered to players, including free spins, matched deposits and exclusive offers that are made available to UK players.

Payout Percentages

A high payout percentage is always attractive and something that we know you want us to take into consideration so that you always have the best chances of winning real money when you play.

Fast Payout

Sites that we have determined pay their players in time and in a safe way always score points and you can be sure will be in contention for a spot on the top 10 list.

Mobile Capabilities

Because what player doesn’t want to play while they are away from home? iPhone and Android supported apps that enable you to put your cash on the line while you’re on the move are always a good thing.

Established Game Providers

Finally, it’s vital that these sites provide you with access to the best games and the most variety so that you have a wide selection of fun options to choose from that will enhance your experience each and every time.

Filters you can use to compare online casinos

At Gambling Casino, we understand that players have their own criteria and ways to determine which casinos they will invest their time and money in.

As such, in order to get a sense of how each of the casinos that we list stacks up against each other with regards to each of the different criteria, all you have to do is use our handy filters and you’ll quickly be able to get a sense of where individual strengths lie.

It’s easy to sort the good from the bad, so think about the different elements and factors that matter to you and our comparison tool will enable you to compare them side-by-side, so that you can make your own judgments.

The criteria that we used to come up with our top online casinos list is a great reference point for anyone that wants to check out other sites that didn’t make the cut and see how they stack up. We are certain that, with this additional knowledge, you will quickly be able to pick out the best casinos and spot mediocre or bad options.

Whether it’s the absence of a mobile option, welcome bonuses and incentives that are less than thrilling, poor customer reviews that speak to slow payouts or bad customer support, all of these factors are worth your attention before you commit your time and money.
