How Our Experts Choose the Best Online Casino Sites

In today's highly competitive online casino industry, it can be hard to discern which sites are worth your time and money. As such, we are here with some practical advice on how best to select an online casino that offers a trustworthy platform along with top bonuses and exciting games.

At Gambling Zone we only review sites that hold a licence with the United Kingdom Gambling Commission (UKGC). Therefore you can trust they are legit. In this section, we cover the key factors that we take into consideration and explain why they matter.

Live Casino Games

Live Casino Games

Live Casino games are a great way to experience the thrill of playing at an online casino while also having a more realistic and interactive experience. We assess the selection of live dealer games available which includes classic table games such as online blackjack, roulette, baccarat and poker. We will look for anything that makes a casino stand out. Some sites provide regular live casino tournaments, or additional game variations.

Variety of Bonuses

Variety of Bonuses

We deep dive into the promotions page of every casino we review to see which offers are available. The welcome offer is usually the most generous and the best casinos provide deposit matches with free spins. We also look for cashback bonuses or other promotions for existing players. We consider the value of a bonus to be a combination of the amount on offer, combined with the terms.

Number of Online Slots

Number of Online Slots

The best online casinos showcase slots from classic three-reel options to modern five-reel videos with unique themes and features. We look at the number of slot games on offer, with many sites in the UK going into the thousands. All players should have the opportunity to find the perfect game that satisfies their playing style and budget.

Many sites offer jackpot slots and progressive jackpots. These offer the opportunity to win big, for a relatively small stake. In our casino reviews, we highlight what types of slots are available.

Security Features

Security Features

Beyond a gaming licence, we also check the site is secure. Casino sites need to pass rigorous audits in order to achieve a licence. SSL encryption ensures that your sensitive data remains safe. The best online casinos use state-of-the-art 256-bit encryption, while 128-bit encryption is also considered safe.

You can check what a site offers by looking for the padlock symbol in the URL of any web page. We also look for third-party certificates such as eCOGRA. These are third party independent audits that test their RNG (Random Number Generator) games.

User-Experience

User-Experience

This is such an important part of the overall experience. How does the site look, feel and perform? If a site looks slick, modern and fresh, we are more likely to register and play.

It is also important to consider how easy it is to navigate. Areas such as bonuses, games, and customer support should be readily available in a few clicks or swipes. Our reviews contain details on how well the site is signposted, what we made of the game filters and if there are any stand-out features that we really enjoyed.

Registration Process

Registration Process

Registering at an online casino should be a simple and straightforward process. First, you need to select your favourite site. Once you have done this, it is time to create an account.

The registration form usually consists of basic information such as name and contact details. If a site asks for banking details, it is a red flag as it is not required during registration. It is important to note that many of the details that the casino site needs to collect are part of the stringent requirements laid down by the UKGC.

Licences

Licences

In the UK, all online casinos must hold a licence with the UKGC. The UKGC holds significant authority and power which allows them to levy fines or revoke licences in the case of fraudulent practices. Gambling Zone only promotes fully licensed sites. Our recommended sites are legit and you can play with peace of mind.

Having more than one licence is normally viewed as an added bonus. This implies that the operator enjoys trustworthiness across multiple markets. We look for licences issued by the Malta Gaming Authority (MGA) and AGCO, Ontario - both are highly respected.

Selection of Casino Games Software Providers

Casino Games Software Providers

Regarding slots and live casino games, it is essential to know that you are playing with the best game providers. Popular gaming providers include Playtech, Global Games, NetEnt, Evolution Gaming, Red Tiger, and Play’N Go. These are widely respected in the industry for their top-notch graphics and reliable gameplay.

Lesser-known ‘copycat’ game providers do not always measure up when it comes to quality standards. It is best to choose an online casino powered by established gaming developers in order to ensure fair play and secure transactions.

Mobile Casino

Mobile Casino

At Gambling Zone we provide reviews and listings of the best casino apps in the UK. We look at factors such as user interface design, game library selection, customer support, and more. Therefore, you know exactly what kind of service each app offers before downloading it onto your device.

Not all online casinos provide a native version, with some opting for an optimised mobile web page. These are usually just as good as the dedicated app. You will find a mobile section in all of our casino reviews.

Payment Options at UK Online Casinos

Payment Options at UK Online Casinos

The best online casinos in the UK offer a range of payment methods, whether you prefer to make deposits and withdrawals using traditional banks or e-wallets. One of the most popular banking options used in the UK is PayPal, a secure, fast and convenient way to make online transactions. Because of that, we rate PayPal highly and look for it when reviewing sites.

As of April 2020, credit cards are no longer legally accepted at UK casinos. This extends to funding your PayPal with a credit card.

Responsible Gambling

Responsible Gambling

Responsible gaming is an important aspect of any online casino. Gambling should be enjoyed responsibly in order to reduce the risk of problem gambling and potential losses. The best online casinos have clear policies on responsible gaming and feature helpful resources such as limiting tools, self-assessment tests, and links to services if anyone needs assistance. It is a legal requirement for casinos in the UK to offer these tools, but some sites go above and beyond.

Loyalty Programs and Rewards

Loyalty Programs and Rewards

Loyalty programs are an integral part of online casinos as they reward players for ongoing gameplay. These programs come in a variety of forms which can be bonus points, cashback or exclusive promotions.

Some casinos provide a detailed ‘tiered’ system where you progress through levels to bigger and better rewards. These types of programs are becoming rare in the UK. We mostly see weekly rewards, such as cashback on losses.

Customer Support Channels

Customer Support

Customer support is the voice of the casino for players so we appreciate friendly and knowledgeable agents. Top online casinos provide a variety of support options, ranging from live chat to telephone and email. 24/7 live chat is our preferred option, as it allows players to access instant assistance without waiting for a response.

Telephone support is also useful when you need more detailed advice or assistance. Finally, email customer service options allow you to send in queries and receive comprehensive responses. Many sites in the UK will provide support in different languages.

Depending on certain conditions that may apply, any money won from those free spins is yours to keep.

Best Online Casino Sites for Mobile Apps

Mobile gaming has become popular for online casino players to access their favourite games. With the continual advancement of technology, more and more people are now relying on their smartphones or tablets to play. The best online casinos have taken note and have created apps which allow players to play on the go. These apps give users the same experience as playing on a desktop computer, but with the added convenience of being able to play from anywhere at any time. Furthermore, many apps also offer exclusive bonuses for users who choose to download them.

Aside from apps, many online casinos now also offer mobile-optimised websites so that players can easily access their favourite games from their smartphone or tablet’s web browser. Mobile sites are specially designed to fit smaller screens, allowing customers easy navigation and quick loading times without sacrificing quality or game selection.

Top 5 Most Popular Casino Games for UK Players

People in the UK have access to all sorts of online casino games. Many UK casino sites have thousands of games to offer, giving members more than enough options to make their time at the site worthwhile. Naturally, some types of games have become more popular than others. Below are summaries of the biggest types of online casino games in the UK.

Online Blackjack

Blackjack

What makes blackjack popular is the fact that it is not just all about luck. While luck does play a role, so do skill and strategy. When playing blackjack, you have to make important decisions about your hand that can affect the outcome. This makes the game compelling and engaging for players. Some blackjack games have slight rule changes and features such as optional side bets that add variety to the gambling experience.

Online Roulette

Roulette

Roulette is the most popular online casino game in the UK after slots, with many enjoying it because of how simple it is. All you have to do is pick one or more numbers and if the ball lands in a pocket with a number you chose, you win. There is a good number of bets you can place in a typical roulette game. These include single-number wagers and bets that cover as many as a dozen numbers.

Online Poker

Three Card Poker

Poker has long been a big hit with UK players because of its gameplay, which requires careful thinking and strategy. It is a step up from blackjack in terms of complexity, though it is still easy enough to learn and play. Many people enjoy playing poker because of how rewarding it is to win and how engaging the gameplay is. As with other table games, there are multiple variants; some suitable for beginners; others for players with more experience.

Online Slots

Slots

Slots are by far the most common type of game at online casinos in the UK. The typical site has hundreds or even thousands of them. They come in an almost endless range of themes and have many different special features, including free spins, respins, pick-me games and Megaways. Some of them have one or more progressive jackpots that can pay out huge sums of money to very lucky players.

Online Baccarat

Baccarat

This is a game where you bet on which hand, the dealer’s or the banker’s hand, is going to win. The winner is whichever hand gets the closest to 9. Baccarat is therefore a card-comparing game like blackjack, but it does not involve player decisions since everything happens automatically. To play baccarat, you simply pick a hand and see if it wins. Many baccarat games have optional side bets.

Popular Casino Sites Payment Methods for UK Players

The best UK casino sites give players plenty of choice when it comes to payments by accepting a good number and range of payment methods. Ideally, there should be at least half a dozen options, and they should include several different types of payment methods. Here are some of the most common types include:

Debit Cards

With debit cards, you can deposit money that you already have in your account. Visa and Mastercard are by far the most common types of debit cards you can use at UK casino sites. The vast majority of British online casinos accept one or both of these payment options, for both deposits and withdrawals.

Prepaid Cards

NeoSurf is a good example of a prepaid card. With this, you purchase a voucher (physical or digital) worth a certain amount of money. The voucher comes with a unique code that you enter to fund your online casino account. Prepaid cards are an option at a good number of UK casino sites, though they are for deposits only.

E-Wallets

Many UK players use e-wallets such as Neteller, Skrill and PayPal to fund their online gambling. What makes e-wallets popular is that they are easy to use, they have fast processing times and they are very secure. There is also the fact that they do not require you to enter bank details every time you wish to make a transaction.

Pay By Phone

For mobile gamblers, Pay by Phone is a common option. With this, you can make a deposit into your online casino account using your phone bill. This is a convenient option for mobile users as it requires just a few taps and the funds will reach your casino account right away. However, you cannot make withdrawals with this payment option.

Top Online Casinos Software Providers

There are a few hundred companies that create gaming content for online casinos. Gambling Zone has put together a list of the best ones, looking closely at their games and how they have fared with players.

Top 5 Tips on How to Choose the Best Online Casino Sites

We have explored many factors in how we rate online casinos, but what steps should you take before picking your next site? Our best advice is to always ensure that the casino is licensed, and trusted. If these two conditions are met then at the very least you will be playing on a level playing field. However, with so many casinos fighting for your attention, it can be tricky to work out which ones are the best.

Check out this handy checklist you can use as a guide to choosing your next online casino.

Look for the licence

You are looking for a UKGC licence number. This can be found in the footer of the page. If you want to make sure it is legit, you can check the number on the official UKGC page.

Examine the game collection

Does it have enough of the games you enjoy playing? Be sure to check the list of software providers to make sure they are well known. Does the live casino offer enough tables? It’s important that a game suite matches your gameplay.

Bonuses

You can shop around for the best casino bonuses before signing up. Take a look at the promotions page to get an idea of what other offers might come after the welcome bonus. Check the terms of the promotion. If wagering is set at unrealistic levels, it could be a red flag.

Selection of payment options

Is there a deposit method that you are comfortable with? Are the withdrawal times reasonable? It is key that you are happy with both of the answers because being able to access your online casino wallet quickly is important.

Read reviews

If you are not familiar with a casino then read unbiased, trusted reviews. Gambling Zone casino reviews show both the good and the bad. We test sites and put them through a rigorous process so you can trust our reviews are genuine.

Casino Sites You Should Avoid

Gambling Zone points readers in the direction of online casinos that are safe and trustworthy. There are a small number of sites that, for one reason or another, you should avoid. Below are some reasons why a particular casino might not be worth signing up to.

Operating Without a Valid Licence

An online casino operating in the UK should have a licence from the UK Gambling Commission. This is the regulatory authority that oversees gambling activity in the UK. Having a licence means a casino site has the approval from the UKGC to operate. When you visit an online casino, scroll to the bottom of any page and you should find licensing information. If the casino does not have a licence, it may not be safe or trustworthy.

Unfair Terms and Conditions

When you join an online casino, you have to agree to the terms and conditions for the site to set up your account. These are the rules you have to follow while using the site. They should be reasonable and fair. It is always a good idea to read the fine print before joining a casino so you know what is going on. If the terms and conditions are too restrictive or extreme, choose a different casino.

Poor Customer Support

The best casino sites should have a reliable customer support system in place so you can get help whenever you need it. Ideally, there should be several ways of getting in touch, including live chat, and help should be available 24/7, if not most hours of the day. If a casino’s customer support system is lacking, it is best to play at a different site instead.

Unpaid Winnings

Most online casinos process withdrawal requests in a few working days or less. If the casino refuses to do this or the processing hits a delay, there may be a scam of some kind going. Before signing up, check if there are any customer complaints to do with payments. If there are such complaints, you should join another casino that has a good reputation for paying out winnings.

Negative Customer Reviews

If an online casino’s reviews are mostly negative, that is a clear sign that the site is not worth joining. On the other hand, when the reviews are nearly all positive, you should not encounter any major issues if you decide to sign up. Gambling Zone focuses on promoting the best casino sites that have earned a lot of positive feedback from players.

How to Sign Up to UK Online Casino Sites

After selecting the casino that best suits your style, signing up and creating an account is relatively effortless. Although each site has its own particular processes, they usually have a lot of similarities. To make it easier, we have compiled a quick breakdown of what you can typically expect.

This should be clearly displayed on the page.

The Benefits of Playing at Online Casinos

Playing at an online casino compared with a brick-and-mortar casino comes with many benefits. In our opinion, there are many aspects to online play that a land-based casino simply can not match. We see three main advantages, let us look closer at them.

Ease of Playing

Being able to play from the comfort of your own home is a major advantage. You can simply stay in your comfortable clothes and you do not need to travel miles to enjoy your favourite games. With the addition of a live casino option, you can also enjoy a fully immersive experience, with some online casinos broadcasting from their land-based counterparts. So you can enjoy all of the thrills without the commute.

Huge Selection of Games

With thousands of games available to play online, it's impossible for a physical casino to fit that many games into their space. Therefore, the choice of an online casino is phenomenal. Furthermore, with many live table options, you do not have to wait for an opening on an online roulette table, whereas you may have to if you visit your local casino. On top of that, online sites can host a wide range of limits to suit every player.

Play Games for Free

When we say play games for free, we are referring to customer bonuses. These are not offered when you walk into a casino, and in our opinion is why online casinos are considered better for players. Free spins bonuses or cash boosts can increase your chances of landing a win, so are valuable.

Who Regulates Online Casino Sites in the UK?

The UK Gambling Commission (UKGC) is the organisation that regulates online casino sites in the UK. Back in 2005, the British government passed an important bill, the Gambling Act 2005. This bill included the formation of the UKGC, which would formally launch in 2007. The ongoing aim of the UKGC is to promote legal and responsible gambling, while working to prevent gambling problems. 

Online casinos in the UK need to have a licence from the UKGC to legally operate. To obtain, they have to pass stringent checks and maintain certain standards. The UKGC has the power to revoke licences and issue fines to sites that do not comply with its licensing conditions.

Online Casino Final Thoughts

The best online casinos provide a safe, secure and enjoyable gaming experience for players of all levels. With so much choice in the UK, players can take advantage of generous bonuses, as well as exclusive games and much more.

At Gambling Zone we pick out and recommend only the best and trusted casinos in the UK. Check out our top list and get started on a highly-rated online casino today.
