How We Rate Online Casinos

So what makes us qualified to be able to rate and recommend the best online casinos? Well, we have a team of experts with years of experience in the field who know exactly what players want from their online casinos. Our experts closely examine each of these criteria to ensure that all of our recommended casinos are up to our high standards. Let’s take a closer look at what we look for.


Every online casino we recommend is fully licenced and regulated by a recognised gambling authority. Having a licence to operate in the UK is essential, as it proves that the casino can meet the player safety and security standards of the UK Gambling Commission. The UKGC is one of the most respected gambling authorities in the world and was set up in 2005 to help regulate gambling companies within the UK.
A licence from the UKGC shows everyone that they’re fully above board and operate a fair, secure site. Getting one of these licences isn’t just a one-time thing. Online casinos must continue to prove that they meet these high standards to keep their licence.

Bonuses and Promotions

One of the major benefits of playing at an online casino is all the bonuses and promotions they offer. Many sites offer generous welcome bonuses to new players, and the top online casinos in the UK even offer ongoing promotions to keep their existing customers happy. Our experts compare the bonuses and promotions on offer across various sites to ensure you’re getting the most value possible.

Design and Usability

An often overlooked aspect of an online casino is its design and user-friendliness. A good casino design is one that you don’t think about – it does its job without drawing attention to itself. Having a good design is essential to a good user experience. You want it to look good, while still being easy to navigate.

Deposit and Withdrawal Options

Another key feature of any online casino site is its banking options. If you can’t quickly and securely move your money on and off the site, you won’t want to create an account! That’s why we look at all aspects of online casino banking. This includes your payment options, minimum and maximum limits, withdrawal times, and fees. We feel it’s important to have all of this information before choosing your online casino. There’s nothing more troublesome than finding a good site only to find that they have high fees or long withdrawal times!

Software Providers

Many people understand why having a good selection of quality games to choose from is important, but just as important is the quality of the software providers. After all, we’re sure you’ll agree that a site with a few hundred high-quality games is much better than one with thousands of repetitive, low-quality games. The software providers are the best indicator of a site’s game quality. The better the game providers, the better the games will be. Also, the more software providers you have to choose from, the better variety of games there’ll be to choose from.

Games Selection

Arguably the most important feature of any online casino is its game selection. A site needs to have hundreds of games available if it wants to compete in today’s market. They also need to meet the quality standards we’ve come to expect over the past few years. Online casinos can’t get away with hosting twenty slight variations of the same game and calling it a day, but players demand variety. Our experts thoroughly examine not only the variety of games available but also the quality of those games to ensure that we only recommend the best of the best.

Payment Options

Being able to get paid out after a winning session in a quick and efficient manner is another thing that’s important to many UK players. Many sites do not offer the same level of withdrawal options compared to deposit options, making it easy to deposit money to the site but hard to get it off. That’s why we have our team of experts not only look at the deposit options but also the payment options to ensure that you have plenty of ways to get your money off the site in a safe and secure manner.


Player security is always our number one priority when reviewing or recommending any online casino. We will never recommend a site we believe to be unsafe, and we take great steps to ensure that every casino we recommend is fully above board. Many of the best online casino websites use the latest security technology to keep your data safe. This includes state-of-the-art 128-bit SSL encryption, firewall technology, and much more! Our team of experts always checks the security measures each site has in place to keep your funds and your data secure.

Customer Support

After depositing and gambling with your hard-earned cash, you want to know that you won’t be left hung out to dry if anything were to go wrong. That’s why we check each site’s customer support team as part of our review. One of the most important things we look for is the team’s availability to ensure that you’ll always get the help you need whenever you need it. We also check the responsiveness and helpfulness of each site’s customer support team, so you know exactly how much help you’ll likely get if anything goes wrong.
How to Choose Top Online casino

How to Choose Best Online Casino

Now that you know how we rate online casinos, how do you find the one that’s right for you? It can be a tricky question, especially if you’re new to the world of online casinos. However, we’d always recommend that you focus on the aspects of a casino that are most important to you, whether it’s the gaming options, the bonuses, or the mobile gaming experience. Here are a few of the key things you should consider when trying to find the best online casino gambling site.

Great Bonuses

The bonuses and promotions are the most eye-catching aspect of online casinos, so it’s no surprise that many people consider them when picking their site. However, it’s important to find a bonus that offers value and is right for the games you want to play. For example, if you want just want to play table games, there’s no point in signing up for an online casino that only offers free spins. The best-rated online casino sites offer generous welcome packages that cater to players of all game types, so make sure you pick one that’s right for you.

A Large Game Variety

A key aspect of any online casino is the variety of games they offer. If you love playing online casino games, this may be the most important aspect to consider. Some sites only offer a couple of hundred games, whereas others offer well over a thousand. Let’s take a look at some of the most common games you’ll find at an online casino.

Casino Game Description Odds of Winning Maximum Winnings
Online Slots Online slots are one of the most popular casino games, with many sites hosting hundreds of games to choose from. The best sites even offer a variety of slot types, including jackpot slots, classic reel slots, and video slots. 2% N/A
Poker Many casinos offer both video poker and casino poker variants. Video poker variants include Deuces Wild, Jacks or Better, and Double Bonus. N/A N/A
Craps Craps is a dice game where players bet on the result of the roll of two dice. There are many different craps bets you can make, including the pass line, the come bet, the field bets, and the place bets. 49.29% 30x
Baccarat A favourite of James Bond, this classic casino game is often offered in both animated and live casino formats. You will often find different versions of baccarat hosted at online casinos, including Punto Banco and Baccarat Banque 45.8% 8x
Roulette This fast-paced casino game has several different variations, all of which you can find at online casinos. These include European, French, and American styles. 49% 35x
Blackjack Blackjack is a card game where players must try to beat the dealer’s hand without going over 21. You can find both live casino and animated versions of blackjack with a number of different betting limits. 48% 1.5x

Easy Sign Up

When starting off your online casino journey, you don’t want to be inconvenienced by a lengthy sign up process. In fact, you want to jump right into the action! Many sites have made great strides in simplifying their sign up processes as they realise they could risk alienating players if they ask for too much too soon. However, some sites still require you to provide proof of ID and address before you’ve even created your account! By checking the sign up process of your online casino before committing to it, you can save yourself from a long registration.

Common Payment Methods Accepted

Being able to easily deposit and withdraw from a casino is a dealbreaker for most people, as they don’t want the hassle of using unfamiliar payment methods. All good casino sites these days offer various payment options, with popular methods such as PayPal, Visa, and MasterCard payment method accepted at most casinos. It’s important to find the sites that offer the payment methods you prefer to use, as it makes the process of depositing and withdrawing a much smoother experience.

Fast Withdrawals

After a big winning session, the last thing you want to do is wait days to receive your money. Online casino payments have taken a big step forward in the past few years, and many payment methods offer 24-hour withdrawal times. However, despite this, many sites still take multiple days to process each withdrawal request. That’s why you should look for sites offering fast payment methods and processing times to ensure you get your money as soon as possible.

Mobile Experience

Gaming on the go has become increasingly popular over the past decade thanks to the advancement of smartphone technology. To take advantage of this, many sites offer mobile gaming options that allow you to experience their full range of games from your mobile. Some sites offer a dedicated mobile app, whereas some offer a mobile-optimised website, so make sure you pick the one that you find most appealing.

UK Casino Reputation

In the gambling world, reputation is everything. If a player has had a bad experience at a site, you best believe that you’ll hear about it, and if they’ve had a bad experience, who’s to say that the same won’t happen to you? Picking reliable online casinos with a good reputation in the UK gambling community means you’re more likely to have a good experience. All of the sites we recommend are highly reputable online casino sites within the UK gambling industry. This means that no matter what you pick from our list of online casino sites, you can be sure of a good experience.

Security and Customer Support

One of the reservations that many people have about online casinos is whether or not they’re safe. While it’s true that back in the 90s, online casinos were a bit of a Wild West, nowadays, the market is much more regulated. Each online casino that operates within the UK must hold a licence, and many of the best sites use a range of high-tech security features, such as firewall technology and encryption technology, just to name a few.

Licensing and Legislation

As we mentioned above, each online casino site operating in the UK must hold a licence from the UK Gambling Commission. The UKGC was established after the UK legalised gambling in 2005 with the passing of the Gambling Act to regulate the companies that operated in that space. Since then, the UK Gambling (Licensing and Advertising) Act passed in 2014, which requires gambling companies to hold a licence from the UKGC to legally offer games to UK players.

Types of Casino Bonus Offers

The best online casinos UK will offer you a range of different bonuses and promotions to tempt you into signing up. Some of these bonus offers are much better than others, so it pays to know which ones are worth signing up for and which ones don’t offer much value. If you’re looking to pick a site based on the bonuses they offer, it’s important to know all of the types of bonuses you’ll encounter. Let’s take a closer look at the types of bonuses casinos will offer you.

Free Spins at Online Casinos

This one is self-explanatory – the casino offers free spins at some or all of its real money online slots. Some casinos require you to make a deposit to claim your free spins bonus, whereas some will give you free spins for signing up or verifying your account. When it comes to free spins, the bigger the number, the better, so if you want to get the most value possible, look for the sites offering the most spins.

Reload Bonuses

While many people focus on the eye-catching welcome offers, it’s the promotions for existing players that will keep you playing long after your welcome bonus has been and gone. A reload bonus will reward you for making a deposit to an online casino after you’ve made your first deposit. This reward can come in the form of free spins, bonus funds, or free bets, but the most common form of reload bonus you’ll see is a matched deposit bonus.

Welcome Bonuses

All good online casinos will offer some sort of welcome bonus, even if some are more generous than others. A welcome bonus is a bonus an online casino will offer to players who have not made an account to try and persuade them to join their site. These bonuses are often the most generous offers a casino will give to its players and can come in many different forms. The most common form of welcome bonus you’ll see is a matched deposit bonus, but many sites also offer free spins as part of the offer.

No Deposit Bonuses

By far the rarest and arguably the best online casino site offers you’ll see find are no deposit bonuses. These bonuses reward you with free spins or bonus money without requiring you to make a deposit first. This essentially gives you money for nothing, which is why they’re both so popular and so rare. The most common form of no deposit bonus you’ll find is a free spins no deposit bonus, but some sites do offer bonus funds, so keep your eyes peeled for them!

Match Deposit Bonuses

A matched deposit bonus is one of the most common offers you’ll find at an online casino. When you claim this bonus, a certain percentage of your deposit will be matched by the casino up to a certain amount. For example, if a casino has a 100% matched deposit bonus up to £100, if you deposit £100 of your own money, the casino will give you an additional £100 in bonus funds.

How to Register at Online Casino Sites

Once you’ve found a site with an appealing enough bonus offer, it’s time to create an account! Luckily, many popular online casinos in the UK market have simple sign up processes, so you can create your account and start playing in just a couple of minutes. You’ll need to enter your personal information when creating an account, so make sure that the site you’ve chosen has a secure connection to ensure that no one else can access that information.

To help make registering at your chosen site that little bit easier, we’ve created a step-by-step guide to walk you through the registration process, so follow along below.

Steps Description
Choose an online casino on Slotozilla Choose your favourite online casino site. Our list contains many great options, so no matter which one you pick, you can be sure of a good experience.
Open the official website of your chosen online casino Once you’ve made your choice, open the official site of your chosen casino. Make sure that it is the correct site, as some shady companies use similar domain names to trick unsuspecting players.
Click on the registration form Click the “Register” or “Sign Up” button on the page. You’ll often find these in the centre of the page or in one of the corners of the homepage.
Create an account Start to enter your personal information, such as your name, email address, date of birth, and phone number. You’ll also need to create a password for your account, so make sure you pick a secure one. Once you’ve entered all your information, agree to the Ts&Cs and click “Register.”
Deposit and choose your welcome bonus Once your account is created, you’ll be able to make your first deposit. Go to the “Cashier” or “Bank” section of your online casino, go to “Deposit,” pick your chosen deposit method, and enter your deposit amount.
Play and enjoy! Now that your account is fully funded, you’re free to play and enjoy any of the great games available on the site!

It’s just that easy! You’ve now created your very own online casino account. However, some casinos will require you to verify your account before depositing or withdrawing a certain amount. You can verify your account by submitting a proof of address document (such as a bank statement or utility bill) and proof of ID (such as a passport or driving licence).

Deposit Options for Online Casinos in UK

Now that you’re up and running with your account, the next thing you need to do is to fund it. Many online casino sites have a wide range of payment options, so you can choose the payment method that you’re most comfortable with. However, it’s always worth checking the deposit times and the fees associated with each payment method to ensure you won’t get hit with any nasty surprises. Let’s take a look at the most popular deposit options at UK casinos.

Debit Cards

Debit cards, such as Visa and Mastercard, are one of the most popular options when making any online payment, and the same holds true for online casino payments. This is because of the security and convenience that debit cards offer, which makes depositing to your online casino a breeze. To make a deposit, simply enter your card details on to the site and enter the amount you’d like to deposit. Your deposit will be in your account and ready to play within seconds.


Another popular online payment method is the e-wallet. These wallets don’t require you to enter your bank or card details, making them one of the most secure payment methods available. All you have to do is enter the amount you’d like to deposit, enter your e-wallet email address, sign in to your account, and approve the payment.


One of the best examples of an e-wallet payment method is PayPal. PayPal is arguably the biggest e-wallet provider on the planet, with over 420 million active users at the time of writing. Many of the highest-rated online casinos offer PayPal as a payment option, making it a great option for UK players.

Prepaid Cards

Prepaid cards allow you to load a set amount of money onto a card and then use that card to deposit to an online casino. This has the benefit of limiting the amount you can deposit, giving you more control over your funds. Plus, it allows you to deposit without giving your card information to the casino, making it a more secure process.

Bank Transfers

While bank transfers used to be considered a slow way to move your money on and off an online casino, many sites now offer instant bank transfers through companies such as Trustly. These instant transfers allow you to make quick and secure deposits to an online casino without needing a debit card.


One of the more outdated but still used payment methods is the pay-by-phone method. Some casinos will allow you to make deposits using your credit on your phone or by charging your phone bill. All you need to do is select the option from the deposit method, enter the amount you’d like to deposit (up to £10), and the funds will be in your account! However, you need to ensure that you have a mobile number associated with your account before choosing this method.


From one end of the extreme to the other, Bitcoin is the most modern payment method on this list and is fast becoming a popular option around the world. However, UK casinos have been slow to accept cryptocurrency as a payment option, and many sites still don’t support it. As cryptocurrency becomes more widely adopted in the next few years, we can expect more and more sites to start accepting Bitcoin payments.

Customer Support at the Best Online Casinos

Customer Support

As you’re depositing your hard-earned money, many sites recognise the importance of having a dedicated team on hand to help you if something goes wrong. The best-rated online casino sites will have a 24/7 customer support team that you can contact in multiple ways.


Some trusted online casinos will have a hotline that you can call so you can speak to a representative directly to ask your question or resolve your issue. However, this is becoming less and less common as casinos pivot to a more digital form of customer support.


Almost all online casino UK sites will have an email address that you can use to contact them. However, the downside to email support is that you often have to wait a few hours to get a response, so if you have an urgent query, you won’t be able to resolve it immediately.

Live Chat

The most trustworthy online casinos will have a live chat system where you can speak to a representative through a chat box. This gives you instant access to the customer support team and doesn’t require you to verify your details, as they can already see your details via your account.

Social Media

An increasingly common support option is social media. Many of the most popular online casinos have a social media presence, and you can message them directly on those platforms to ask questions or raise concerns about your account.

Contact Forms

Some online casinos won’t provide players with an email address on their site but will rather have a contact form that can be filled out and sent to the customer support team. The support team will then pick up this ticket and contact you via the information you give them in the contact form.

UK Online Casinos Licensing and Legislation

The UK has long had a relaxed attitude towards gambling, especially when compared to other European countries. This can be seen as early as 2001 when the UK Government abolished the Betting Duties tax. This means that UK residents no longer had to declare their gambling winnings or losses or pay tax on any gambling winnings.

Four years later, the UK passed the Gambling Act, which legalised all forms of gambling within the UK. This Act updated older gambling laws that were several decades old and not equipped to deal with the modern forms of gambling that were now available to the public. The three main aims of this Act were to ensure that gambling remained fair and open, protect vulnerable adults and children from gambling, and ensure gambling remained crime free.

Part of the way it would achieve these goals is through new, more stringent regulations. As part of the Act, the government created the UK Gambling Commission. This independent authority would regulate all forms of gambling in the UK, with the exception of spread betting and the National Lottery. This Commission would be responsible for awarding licences to gambling companies that could meet their requirements, which included proof of funds, proof of fair games, and proof of security.

In 2014, the UK passed another Act, the UK Gambling (Licensing and Advertising) Act. This made it mandatory for every gambling company to obtain a licence from the UK Gambling Commission to offer real money games to UK players. This ensured that UK players could only play on sites that have been deemed safe and fair by the Gambling Commission.

Gambling in the UK is some of the safest in the world, thanks to the efforts of the UKGC.

Problem Gambling Help

Problem gambling is a serious problem that affects around 0.2% of the UK population, or around 130000 people. While many people enjoy gambling as a form of light entertainment, it can be extremely dangerous for problem gamblers, so we encourage our readers to seek help if they or someone they know is affected by problem gambling. There are many companies in the UK that can assist with problem gambling, and you can find information on these companies below.


GamCare is one of the country’s leading providers of information and support for anyone affected by problem gambling. The company operates the National Gambling Helpline and provides treatment for anyone who has been harmed by gambling.


Telephone: 0808 8020 133


GAMSTOP is a free online self-exclusion scheme that helps problem gamblers limit their access to online gambling. Once registered with GAMSTOP, you will not be able to gamble at an online casino for the duration of your self-exclusion period, even if you already have an account open. This is because every online casino in the UK must cross-reference your details with GAMSTOP every time you log in or register an account as part of their licensing conditions.



BeGambleAware is an independent charity that provides information to help people make informed decisions about whether or not gambling is right for them and provides support to people who suffer from gambling addiction. They offer lots of information on supporting yourself and others who may have issues with problem gambling and are a great resource to use if you know someone with this issue.


Responsible Gambling Tips

We at Slotozilla always encourage our readers to gamble responsibly, as that’s the best way to ensure that gambling stays fun. There are many things you can do to ensure that you gamble within your means, but if you’re looking for ways to manage your gambling, take a look at our helpful tips below.

  • Budget Your Gambling – Always have a set budget for your gambling and stick to it. The problem that many people face is that once they’ve used up their allocated gambling budget, they go beyond their budget to keep gambling. However, if you stick to your limits, you’ll be able to gamble much safer.
  • Use Deposit Limits – One of the best ways to ensure that you stick to your budget is to set up deposit limits. Many online casinos have built-in tools that allow you to set daily, weekly, and monthly deposit limits on your account, making it easier to control your gambling.
  • Take Regular Breaks – It’s easy to lose yourself when gambling online, so taking regular breaks from gambling is a great way to ensure that you stay within your limits. Some of the most reputable online casinos have “Reality Checks” that alert remind you to take breaks every 10-60 minutes.
