At OnlineGaming4u, we have helped thousands of players across the UK choose the right casino site by comparing what the gambling market has to offer.

Our range of suggestions, guides and tips on things to look out for when choosing a gambling site is second-to-none, and the fact that this informtion is based on real-life customer experiences and factual criteria is priceless..

Advice for selecting online casinos

Advice on Selecting Online CasinosFiltering and sorting casinos by category is a great way to narrow down your search. Especially if you are looking for a particular game or category of game to play, such as roulette or slots.

Why do we recommend filtering?

Each person is completely different when looking to play at an online casino, and they often have their own preferences on what they do and don’t like, such as device, software, games and bonus.

Therefore, when starting your gambling journey online, it is important to think long-term, rather than short-term.

Many people make the mistake of jumping in to an online casino site feet first, often attracted by a new bonus, but it’s crucial to consider how the operator can best serve you in the future, as well as now.

Based on experience, we know a lot of players think that playing at casinos is short-lived, but the reality is – the majority of players return time and again to the same casino site, especially if they offer multiple product verticals such as slots, table games, live dealer, instant-wins and sports betting.

After all,ask yourself whether or not it’s better to join one site that offers the complete package of gaming products with hundreds of games, or four different sites with individual products.

Multi-product casino sites for slots, table games and live dealer

Multi-Product Casino SitesAs we mentioned earlier on this page, lifespan and retention are two very important qualities when it comes to choosing an online casino site.

Casinos that provide multiple products are more likely to be keepers, whereas those that provide a limited gaming experience are likely to attract fly-by-night bonus hunters.

The most common retention factors that keep players playing and engaged include:

  • New Games – how often are new games added?
  • Loyalty Bonuses – does the casino reward existing players regularly?
  • Reload Bonuses – will the operator keep giving you deposit bonuses beyond the initial welcome bonus?
  • VIP Treatment – are prizes awarded for VIP players, or high rollers, who play frequently or gamble larger amounts?

Choosing an online casino site in the UK

Choosing an Online Casino SiteOnce you have the knowledge and understanding of what makes a good casino and how to find one, the next step is to actually pick one!

However, this is the step that people often get overwhelmed with.

Some players dive straight in because they think that all casinos are the same, but they’re definitely not.

There’s so much for you to consider when picking a new provider:

  • Device
  • Wagering requirements
  • Bonus type
  • Payment method
  • Software
  • Game selection
  • Customer support

Since 2006, we have been reviewing gambling sites on a massive scale. Our team has personally vetted more than 1000 gambling providers along the way, including mobile and online casinos, bingo sites, poker sites and bookmakers.

Our vetting process is intricate and covers all major talking points when it comes to online gambling. This helps us to provide expert editor opinions, customer reviews, previews and comparisons.

Popular UK casinos online

At OnlineGaming4u, our team of gambling experts test a new online casino each and every day. We are constantly adding to our comprehensive database of casinos to ensure we are providing the most up to date information on the newest and best casino sites the internet has to offer.

This means our ratings are constantly changing and our rankings are shifting with current trends.

Not only do we provide the latest information that is vital to our user-base, but we focus purely on the popular details that gamblers want to see, including the bonuses that casinos are offering, reviews from experts, feedback from past and current customers, and pros and cons.

How we review online casinos for UK players

How We Review Online Casinos UKOur online gambling directory features the latest online casinos in the UK, with information that outlines the core details what people are looking for.

In order to review a new online casino, our team carry out a seven point health-check on all sites before considering any recommendations, including operators that contact us for a potential listing.

Our seven point health-check includes:

  1. Overall casino experience from initial sign-up to withdrawing money.
  2. Promotions and bonuses for both new and existing players.
  3. In-depth research and feedback from real customers.
  4. Terms and conditions attached to any promotional offers, including realistic wagering requirements and playthrough duration.
  5. House edge and RTP on the casino’s entire portfolio of casino games and slots.
  6. Customer service and support across multiple channels at different times of day.
  7. Legality, regulation, licensing and security.

Dynamic casino site rankings – Fresh content always

The team at OnlineGaming4u has been formed by people from different backgrounds and all walks of life. The knowledge and experience between them means that they can supply buckets of helpful tips and advice on a range of back-of-house topics that make up a casino operator’s success.

In fact, our team has developed its own ranking system, which combines the most advanced algorithm with a database of knowledge and criteria so that casino listings and rankings are fluctuated automatically.

As new casino providers burst on to the scene, as mentioned in the section above, they are automatically vetted and manually checked as part of our in-house processing protocol.

A worthy mention about our system is that rogue casinos and negative operators are also stored in our database, but are intelligently excluded from our frontend site. This allows us to list only safe gambling providers for you to compare and choose from, with peace of mind knowing that a trustworthy site is the minimum benchmark for any brand.

Legal and fair casino sites you can trust

Online casinos that we recommend are completely legal in the UK and are regulated by the Gambling Commission for safe and fair gaming in a responsible environment.

Casino and betting providers that provide online gambling services on games and sports are safe and run secure servers, also known as SSL, to protect player data and keep transactions secure between customers and companies.

What to look for in a online casino – Top attributes

Top Online Casino - What to Look forAt OnlineGaming4u, we often get people coming to us asking which casino is the best, and although we can point them in the right direction, there isn’t any one casino that is above all the rest.

Each casino we recommend has pros and cons, and where one site may be superior on the bonus front, their graphics and game selection might not match up to its competitor.

Therefore, we are constantly trying to bring you a diverse range of top-rated online casinos so that you can make your own decision based on your individual preferences.

The list of casinos that we display is based on a number of criteria, from expert ratings to actual customer reviews and experiences from within the online gaming community.

In addition to this, we are all about ease and convenience, so we like to think comparing casinos on our site isn’t a difficult task for you.

Due to the high number of online casino operators on the market at the moment, we highlight a few of the top rated sites so that you can spend less time searching and more time playing the games you love!

Over the years, we have spent hours, weeks and months trawling the internet for the best rated and most reviewed online casinos and brought them all to one easy-to-use portal.

Once our list of casinos is compiled, we run a comprehensive checking system on individual sites, along with reviewing them ourselves to rate them and get a true and genuine feel for what the site has to offer before listing them in our directory.

If you are wondering how to spot top casino sites from the rest, here is a few points to look for when searching online:

  • 5 Star rating: how many stars does the casino get in its rating on average across multiple sites and how many votes is it based on?
  • Bonus: how much is the casino site offering for you to sign-up with and what ongoing promotions are on offer, including reload bonuses and loyalty rewards.
  • Customer reviews and opinions: what do other people say? Read at least five customer reviews from different sites to better understand the experience you may have with the casino provider.
  • Expert reviews: are the reviews mostly positive about the casino and what qualities are highlighted that may catch your attention?

OnlineGaming4u has been in the gambling industry for decades. During this time we have been asked hundreds of familiar questions by our visitors.

These questions are asked by users with all levels of knowledge and experience, from beginner to experienced seasoned gamblers.

In light of this, we have put together knowledge-base-style answers that cover a few of the most common questions that people have asked us over the years.

Best UK casino security and payment processing protocols

Online casinos and gambling sites are required by law to follow a strict data protection policy. This includes both personal information, such as name, address, email, and financial data such as debit card details.

Gambling sites also have to operate in a secure online environment with top-level security and encryption when carrying out payment transactions. Similar to that of generic online stores when selling products online.

However, when it comes to gambling online, some people are more wary about safety and security of sensitive information than others. But it is good to know that all UK gambling sites should be following the same protocol in this area in order to comply with their licensing requirements.

Beware of rogue casino operators!

Unfortunately, as with any industry, there is always a small minority that spoil it for others. These are known in the industry as rogue casinos, and often have been caught out for engaging in rogue activities or showing unfair behaviour.

For example, some casino providers cut corners on player safety, or are not as strict with data protection as they should be.

Therefore, it is imperative that you play casino games for money only with a provider that is 100% safe and trusted.

Trustworthy real money casino sites

Trustworthy Real Money Casino SitesWhen looking for trustworthy casino websites, a good place to start is gambling review sites (like OnlineGaming4u), who constantly check hundreds of providers and put them through a vetting process. Only sites that tick all boxes are safe to be listed on these websites.

Additionally, there are also a number of gambling guides in the UK that provide a list of known rogue casinos that real customers have complained about and warned others to avoid.

Furthermore, we have also listed a few points that you should look for when choosing a trusted gambling site, including:

  • SSL and HTTPS: Online gambling sites should use both SSL encryption and HTTPS. This means that the site is encrypted and not vulnerable to eavesdropping.
  • Strong Online Profile: Most safe providers tend to have a strong online profile and high social media presence with plenty of customer feedback and interaction.
  • Clearly Visible Information (Transparency): Trusted gambling sites clearly display their company information, background, company profile and are active in customer support channels such as live-chat, forums or email.

Download casinos Vs Instant casinos

Before casino apps, download casinos were dying out and very few operators provided software to be installed on a computer.

However, since the rise of mobile and tablet gambling over the last decade, apps have put download-casinos back on the map.

Below is a list of a few comparisons between download and instant casinos:

  • Instant casino games are played instantly via a web browser. Whereas download casinos use software or apps that install on your device.
  • Some providers offer less games at their instant casino compared with their download counterpart.
  • The amount of payment methods that you can use to deposit and withdraw is sometimes limited at download casinos.
  • Download casinos require disk space in order to be installed on your device.

There are many pros and cons of each option and often it comes down to personal preference as to whether download or instant casinos are better.

Claiming online casino promotions in the UK – What you need to know

Claiming Online Casino PromotionsBonus offers come in all shapes and sizes and top casino sites usually display clearly how you can claim a bonus underneath the offer they are advertising.

In fact, most modern online casinos give away a free welcome bonus to all new customers when they join and make a first deposit, unless they are a no-deposit casino provider, in which they provide free bonus funds without spending your own money.

The most common first-time bonuses are; welcome bonuses, first deposit, no-deposit bonus, free spins and sign-up bonuses.

Bonus opt-out – Why and how

Rather than opting in, some online casinos will allow you to opt out of claiming a casino bonus.

If you’re wondering why you would ever opt out of a bonus, then it’s worth remembering that all bonuses come with small print terms and conditions, often called wagering requirements, which can limit your casino game activities, including the amount you can win or withdraw.

Why real money bonuses at UK casino sites are the norm

UK online casinos, like other operators around the world, set their own rules when it comes to bonuses.

Players have the potential to win real money, but there are many factors that come in to play, including what type of bonus is being used and the terms attached to it.

For example; no deposit bonuses have different requirements from first deposit bonuses.

With no deposit bonuses, each player has the potential to win real money without making a deposit, but the amount they can win is usually capped or limited, e.g. max £100.

This means that if you win £150 from your no deposit bonus, you can only withdraw £100 and the remaining £50 will be written-off.

That is why many casino players look for flexible bonuses instead, such as deposit-match offers, which are not capped.

However, these have wagering requirements that must be met and played-through before any winnings can be withdrawn, and are usually a multiplication of your deposit amount.

Getting your winnings from UK casinos online without restrictions

The easiest way to win real money from online casinos that is not restricted by a cap or wagering requirement is to play without claiming a bonus.

Some casinos do not allow you to opt-out of a welcome bonus, which is usually awarded on your first deposit. So make sure you find a casino that allows you to opt out and does not force a bonus upon you.

This way, when you play games, you are playing only with your own money. So any winnings can be paid to you without limits or restrictions.

Best casino site software – Providers of slots and casino games

Best Casino Site SoftwareThe backbone of all online casino sites is the software that they provide, which in turn is responsible for the games that are on offer. Each operator partners with one or more software developers in the iGaming industry to offer customers games to play for money.

After all, it is the games that players come for and the games that makes for any enjoyable casino experience.

On the contrary, a poor selection of games can turn players right off a particular casino and may even result in them closing their member accounts.

In our experience, a casino site can be all-singing and all-dancing in terms of interface design and bonuses, but if it is lacking in both quanitity and quality of games than customer satisfaction levels are compromised.

For this reason, the best casino sites on the UK market tend to be the operators that partner with multiple software companies in order to offer a comprehensive and diverse games portfolio. This typically includes three to four ‘big hitters’, along with two or three smaller, less established brands. All of which are able to provide top casino games and new releases on a regular basis.

Below is a list of the current iGaming software providers that the best casinos are offering to UK players across a range of categories, including slots, live dealer games and RNG table games.

Top 15 casino sites FAQ


What is the best casino site in the UK?
Although casino sites are ranked in order from one to ten and beyond, each player has their own preference on what they consider the best, based on a variety of factors. The best sites will provide a great choice of casino games, multiple software developers, flexible payment options and generous bonuses.

Are UK online casinos legal?
Yes, all UK online casinos are legal in the United Kingdom providing they hold a valid license from the UK Gambling Commission. However, any casino site that does not hold a license is considered illegal and should be avoided.

Protecting customer information and financial data is of paramount importance.

Are mobile casino games available at UK casino sites?
Yes, every modern online casino in the UK now offers mobile casino games due to the popularity of mobile usage across the country. Casino sites recommended on OnlineGaming4u are mobile-friendly and have been optimised for mobile browsers such as Safari. You can also download mobile casino apps for your IOS or Android device to play games directly without loading a browser.

Which casino games are available to UK players?
The UK casino sites that we recommend offer almost every game you can think of in the online gaming industry. There are hundreds and even thousands of games to play at some top sites online, including slots with progressive jackpots, table games like blackjack, roulette and craps, and live dealer games. Live casino games offer players an interactive and immersive experience with real dealers and action that is streamed live in real-time.

What online casino has the best paying games?
Across the whole of market, online casino sites all have the potential to offer the best paying games with low house edges. The lower the house-edge, the higher the potential of paying out. Any casino that offers blackjack has the best paying game due to its natural low house-edge, or slots with RTP of 97% or higher are considered good paying-potential games.

Do I have to pay tax on casino winnings?
No. Winnings from online casinos in the UK are not taxed and players do not need to worry about paying tax on the money they win. Instead, it is the online gambling operators that pay tax, not customers.

Can casino games be played for free in the UK?
Online casinos and gambling providers are not allowed to offer free to play games or demos without registration anymore. However, players that verify their age, or register at an online casino can play games for free.

How do casino bonus offers work?
Each type of casino bonus works differently from eachother. The most common bonus offered by UK casino sites is a first deposit bonus, which matches your deposit with a certain percentage for free. No deposits and free spins do not require you to spend any more and reload bonuses are generally offered to existing customers as a ‘buy in’ incentive, which works in the same way as a deposit-match bonus.

What payment options are available at UK casinos online?
Operators allow players to make deposits and withdraw funds via bank transfer, debit cards, including Visa and MasterCard, and e-wallets such as PayPal, Neteller and Skrill among others. Credit cards are no longer allowed at UK online casinos since being banned in April 2020.
