Always choose casinos with a visible UKGC license and clear terms and conditions. This ensures safe play and transparent withdrawals.
F.A.Q.
Why don't we publish the Welcome Bonus offered by UK online casinos?
Well, this is a very serious matter. Basically, due to the stringent regulations set by the UKGC, should we decide to publish the welcome bonus of each UK online casino we mention here, this needs to be done with 100% accuracy, including publishing the T&Cs of each offer, without making any mistake! This would be impossible for us to follow even on a weekly basis, simply because online casino bonuses tend to change their bonuses even on a daily basis!!! Therefore, we have decided that it's much better for the reader to check directly on the gambling sites we have featured thus avoiding any mistakes from our side.
Are UK online casinos legal?
Yes, absolutely! If you decide to play at any of the above mentioned casinos you will be 100% safe and secure. This doesn't mean that the other casinos published on our site are not legal, but although they hold a gambling license, it's not valid for the United Kingdom and therefore they do not accept UK players.
Is there an age limit for playing at online casinos?
Yes, you cannot register and play at online casinos if you are not at least 18 years old.
How do online casinos work?
All the best UK online casinos work in the same way. Players must register with them first, then make the first deposit to be able to play at the online casino. When it comes to casino games and results, these are driven by random generators, so-called RNGs, which are algorithms that guarantee that each outcome is 100% fair and unpredictable.
Which is the best UK online casino to play?
This is a tricky question to answer. It equals to asking the same question about cars, motorbikes, fridges, computers, etc. Basically, it all depends from what you wish to do on a gambling platform and wether you are mostly interested in gambling at casino games such as roulette, slots, card games and so on, or eventually betting on sports, or even both on the same platform. It's up to you as a player to choose among the operators that have qualified to have a place on our website. Trust us, this has not been an easy task for us to publish only the BEST UK ONLINE CASINOS of the hundreds of gambling sites available! Just visit them, but don't base your choice only on the highest welcome offer available. In any case, you will definitely have a positive gambling experience with any of the casinos listed here!
What games can be played in an online casino?
Let's say that some modern online casinos offer an incredible variety of hundreds, and in some cases even thousands, of different games on the same platform. However, you need to visit each casino to verify by yourself the games available, that in the majority of cases always include: slots, roulette and card games; Many online casinos offer also sports betting, virtual sports, live casino, bingo, lottery, scratch cards and other specialty games.
Is it safe to play at live dealer online casinos?
Thanks to internet, the worldwide success of live casinos is absolutely amazing, and they are the main reason why so many land-based casinos have been hit financially, including the world famous Las Vegas casinos. Most online casinos are offering live dealer tables 24/7, with many having multilanguage live dealer tables, and they are broadcasted through the same casino platform, thanks to 100% secure encrypted video cameras. They bring the games in real time on your computer or mobile device, and the same license, rules and security systems apply as per the online casino computerised games.
What are the most popular casino games in UK?
Although it's not possible to account exactly how much money is spent on each game at online casinos, but the king or queen of all games at land based UK casinos is roulette. This doesn't come as a surprise for the simple reason that roulette is fun, easy to understand, fast-paced and sociable. Whereas slot machines do not offer any interaction with other players, and it can make you feel lonely to seat and spin the wheel by yourself. However, for what regards online casino games it might be just the opposite due to the huge number of slot games available at each gambling site. Let's not forget also that slot machines can award multi-million payouts to lucky players.
What casino game do you have the most chance of winning?
Probably Blackjack has the best odds of winning, with a house edge of just 1% in most online and live dealer casinos. Another interesting game is French Roulette with the so called "La Partage" rule, where the advantage for the house is reduced to 1.35%; When you consider that American Roulette has an average of 5.3% advantage for the house, you really have the best chance of winning when playing the "French way".
What are UK online casinos (RTP) payout percentages?
The payout percentages (RTP - Return To Player) at UK online casinos can be between 75% to 98%; This does not mean that if you play £100 you will automatically get a refund between 75 to 98 pounds. What it means is the average payout of an online casino on the total wagered by all players at the different games offered by the gambling house. For example, if a game has a RTP of 90% it means that the house edge is 10% on the total amount wagered by all players.
Are UK online casinos fair and honest?
They must be! All UK online casinos are licensed by the UKGC (United Kingdom Gambling Commission) and as such they must provide 100% fair outcomes for all casino games. Moreover, they always make sure that everything works impeccably, and they operate with high fairness standards, or risk losing their license. So, if you register with the best casino sites we have chosen, you have nothing to worry about in this regard.
How to recognise and choose a safe online casino?
The first thing you need to do is check at the bottom of the casino homepage if the casino holds a gambling license.

If they do it's automatically safe to play there and enjoy yourself without any worries.

Why do online casinos offer bonuses and promotions?
Have you seen how many online casinos there are on the internet? There are so many that the welcome bonus is needed to attract new players! However, beside that, online casinos will have the chance to enhance your gambling experience. Basically, by offering you a welcome bonus they will also have the opportunity to see what kind of player you are, if you love green tables or slot machines. In this way they will send you further offers that they consider most suitable for your profile, so to hopefully keep you as their loyal customer.
How to get casino bonuses?
Bonuses are easy to redeem, but the process is different at different online casinos. Often the bonuses are so featured that it’s hard not to see them. However, you can search for more information about bonuses by finding on each online casino homepage a button like “Promotions” or “Bonuses”.

What is KYC?
It stands for “Know your customers”, which is in practice, a generally accepted protocol in the financial world. The purpose of KYC is to check customers identity so to reduce for example, money laundering or prevent criminals from financing terrorists globally. This is a good protocol that all legal online casinos must adhere to, and that we totally agree with.

What is RNG
Random Number Generator (RNG) is a feature that ensures all gaming results are random. This means, for example, that roulette numbers, video slot results or cards are dealt at random, and that there are no specific pre-loaded patterns. Therefore, when an online casino has the RNG feature in place it's a guarantee that the casino is fair and honest.
What happens if the internet connection is lost/disconnected while you are playing?
Legalised online casinos have certainly thought about this issue and therefore they have a policy for such events. In general, if it happens right in the middle of the game, the casino gives back your bet as if the session never happened.
Can I win real money in UK online casinos?
Of course you can win real money and get paid. If during the registration process you give the casino your real name and other truthful relevant data about you that is requested in the sign-up process, you will be paid without any hassle. What is important to understand is that there are no guarantees when gambling, you can win and you can lose, and winnings should never be considered a prime source of income.
Do I have to pay tax on gambling winnings in UK?
If you play at legal UK online casinos you don't have to pay any tax on your winnings, because this duty is already being fulfilled by the casino itself. Therefore, you get the full clean amount of your winnings.
How can I deposit and withdraw money at an online casino?
You can deposit and withdraw money from trusted casino sites quite easily, as all online casino sites use multiple electronic financial transaction services such as (e-wallets, debit cards, bank accounts) to give players the opportunity to use the method that suits them.

What happens if I have a dispute?
You can raise complaints with the casino, and if unresolved, the case may be handled by IBAS for independent resolution.
Can I get support 24/7 if I have a problem?
Another important thing to check when looking for the best rated UK online casinos players can play peacefully, is the availability of customer service. As problems with withdrawing money or choosing the most appropriate payment method can arise at any time, employees of the web platform should be available 24/7. Most online casinos we have listed on this page do offer exactly such type of customer service. You can therefore sign up with any of them to enjoy a truly positive gaming experience.
