Online gambling has existed as a concept since the late ’90s and early 2000’s when the internet was still in its infancy. Years later, we have mobile gambling, crypto casinos, and e-sports betting as part of the normal online gambling experience.

But the rise in popularity and the constant increase of new casinos on the market has left a big gap for scammers to come through. Namely, there are casinos that have only profit in mind, with unfair and unclear wagering requirements, lower RTP than stated, and almost non-existent customer service, among other things.

In order for players to get the best and safest casino experience, the UK Gambling Commission and other similar gambling authorities are making sure that the casino’s practices are in line with their safety measures and that customers will not be abused.

Aside from the UK Gambling Commission, there’s also the Malta Gaming Authority which is also well respected in the online gambling world. Seeing their logo on any casino website brings players the peace of mind that the casino site in question is legal, regulated, and licensed. Because we’re talking about the use of real money, many casinos use that against players and have really unfair house edge.

License and legislation for UK Casinos

Choose the Best Online Gambling Sites

The best casino should have a license, a wide variety of games and offer the most convenient bonuses.

Important Criteria

  • Variety on payment methods
  • Different types of bonuses
  • Customer service support (chat, phone, e-mail)
  • Live games

In order for an online gambling establishment to offer its services in the UK, it needs to be regulated and licensed by the UKGC. The Gambling Commission was set up under the Gambling Act 2005 in order to regulate commercial gambling.

All UK online best gambling sites and establishments, including sports betting sites and any other type of real money gambling sites, need to be licensed and regulated by the UKGC and follow their strict rules of operating. The authority of the UKGC has led them to become a sort of framework for other gambling authorities because of how strict their rules for operating are.

This way, the UKGC protects the players and allows for safe and legal casino gaming where they can enjoy playing without worrying about being scammed. The UKGC protects the casinos as well, from players who use loopholes to their advantage, so gambling websites can offer the best experience without worrying that they’ll get taken advantage of.

How do gambling authorities protect players?

You’ve probably read in many casino reviews and articles about the gambling UK Gambling Commission, the Malta Gaming Authority, Kahnawake Gaming Commission, and many others, and just seeing the logo of just one of these on the best online casinos brings you peace of mind. But do you know how they protect players? There are several parameters that they follow in order to ensure player safety and they won’t hesitate to fine the casinos, suspend their license, or even revoke it completely.

  1. Fairness of Gameplay – There are many game developers on the market and that many gambling sites, but not all of them offer fair casino games. Gambling authorities normally have a list of approved game developers so if a casino wants to get licensed, it has to offer fair casino games from proven software developers. This protects the players’ investments and leaves no space for messing with the house edge and RTP percentage..
  2. Personal Data Protection – Perhaps the number one problem with shady and unregulated online casinos is the personal data protection – or lack thereof. Online casinos require a lot of personal information for signing up, making the 1st deposit, and even for withdrawing winnings, but most are unclear on which steps they take to ensure their safe-keeping. Gambling authorities make sure that the online casinos prove that they take all the necessary steps in order to protect the players’ personal data.
  3. Responsible Gaming – Gambling can be quite addictive, to the point where it becomes a problem. Most of the online casinos only say that they offer help however they truly don’t. All casinos registered and regulated under the UKGC, must have protocols for identifying problem gamblers as well as solutions like self-exclusion and deposit limits. It goes without saying, but a strict rule online casinos must follow is the prevention of online gambling for minors. This is something that isn’t taken lightly and is checked thoroughly by the authorities.
  4. Complaints handling – Aside from their own customer service, gambling authorities require online casinos to collaborate with an independent, third-party body that will take over complaints handling. Players can place their complaints there when they aren’t satisfied with the customer service of the gambling site in question. This offers more ways to resolve any issues that players might have with an online gambling site.

New Casino sites vs. Well-know Casino brands

Trying out a casino is always fun and exciting, whether it’s a new casino site or a well-known and already established gambling house. New best online gambling sites have to do everything they can to stand out from the crowd and attract new players so they always try extra hard. They usually have a very generous bonus offer with no deposit bonus and free spins, stellar game selection, popular payment options, and faster deposit and withdrawal processes. Trying out a new casino, however, does come with its own risk, as new players don’t really know what to expect.

Already established casino brands, on the other hand, have a reputation to uphold so players more or less know what to expect from them. While it doesn’t quite have the thrill of trying something new, as is the case with new casino sites, players know what to expect and know that it’s a reliable and legal casino. While they may not be as creative with the deposit bonus offers and the bonus amount may not be as high as the new casino sites’, playing at an established casino brand is just as exciting. In the end, it all boils down to the player’s preference, but one thing is for certain – online gambling should be safe, legal, and fun.

Trends in online gambling

The online gambling industry is an ever-changing one as it keeps growing in popularity. For the best online gambling sites to stay on top, they need to follow the latest trends in the industry as it could make or break them. As with anything, there are certain trends in the online gambling world that we think will separate the good from the bad casinos and show which ones will stay on top.

Mobile Gaming

Mobile gaming has been quite popular, especially in the last few years and it seems like it will only continue to gain popularity. Many casinos offer a mobile app or at least a mobile-optimized web page, but as far as trends go, we believe it’ll get to the point where casinos won’t do well without an app. As one would expect slots to be part of the games offered, mobile apps would soon become an integral part of a casino.

VR Gambling

Virtual Reality has become a commercial success, with its applicability in almost any field. Online gambling is one field where VR is still in its infancy but it does hold a lot of promise for the year that follows. Online gambling is already convenient enough, however, VR will make it even more so, with players being able to get the closest to the real brick-and-mortar casino experience without ever leaving the comfort of their own home. Live casino games are already popular but imagine what a little VR can do?

Blockchain Casinos

Blockchain is a hot topic at the moment and it comes as no surprise that it’s also part of the online gambling world too. Cryptocurrency is a valid payment method in many casinos, . Because of the reliability and convenience of cryptocurrency as well as gaining commercial traction, it could become a vital part of the payment methods of many online casinos.

E-Sports betting

Online sports betting is nothing new, especially since sportsbooks have been around for a very long now. With the recognition of playing computer games as a legit sport, it has paved the way for many opportunities such as e-sports better. As a lot of online casinos offer sportsbooks as part of their services, we expect many to put e-sports betting on their list of services too. It shouldn’t be long before all of the best online gambling sites in the UK that have sportsbooks add e-sports betting into the mix.

A Decrease in Land-Based Casinos

With everything that was mentioned above, a decrease in land-based casinos doesn’t come as a surprise. While it may not be a trend technically, it is something that will inevitably happen as more and more people turn towards online gambling. This is not to say that brick-and-mortar casinos will completely cease to exist, however with the lack of interest, it is sure that they will decrease significantly.

Emerging Markets

Because of the growing popularity of online casinos, there’s a possibility for a smaller list of restricted countries. It seems that many countries are looking into establishing a gambling authority that will regulate and license the gambling operators within the country. We expect more countries to legalize and regulate online gambling and thus have new, emerging markets where players can play freely and most importantly – legally.

Gamification Casinos

Gamification is another feature that the best online gambling sites have started to implement. In addition to the casino games everyone loves, casinos have now started to add mini-games, trophies, collectibles, and other forms of gamification in order to make the gambling experience even better for players.

Crypto Casino Sites and Regulations

Cryptocurrencies are the current rave and are becoming applicable almost anywhere. Because of how flexible and private they are, cryptocurrencies are the preferred method of payment for many gamblers. Now, with its rising popularity and demand, more crypto-based casino sites have opened up where players can choose between several popular cryptocurrencies like Bitcoin, Etherium, Dogecoin, and more.

When compared to fiat currencies like the dollar or the pound sterling, digital currencies are more flexible and independent. They’re not tied to any particular bank or country and thus are very private. They are however very volatile and their store of value can change almost overnight. While Fiat currencies, on the other hand, are more stable, and their store of value is set by Central Banks so you can be sure that if you have 100 pounds today, they will be the same value 30 days from now.

As good as being so independent is, it also comes with its downsides as there are many unregulated crypto casinos that can swindle you out of your money. This is a problem with fiat currencies too, however, given how valuable digital currencies are and how their value fluctuates, it will hurt your pockets way more.

The UKGC advises players to search for licensed crypto casinos so that they can be sure that the online gambling site of their choice is reliable and legit. Digital currencies are also very susceptible to theft, hacking, and other criminal activities so players should be very careful.

Mobile Casino sites

With the constant improvement and advancement of technology, it’s no wonder the demand for mobile casinos is so high. For players who like to gamble online, it shouldn’t be a problem to play at an online gambling site from their mobile phones.

Many casinos have first started as mobile-only casinos and have then ventured into the PC version but there are also many that have been PC-only first but have followed the trend and are now accessible through the mobile phone.

People who like gambling online have a choice between a dedicated mobile app and a fully optimized mobile website where they can access the casino through their mobile browser. Either way, almost all of the casinos are available for mobile play and all of the functionalities and most of the games are available on the mobile version as well.

Sports Betting Sites

Sports betting is a popular online gambling type that’s been around since the opening of the first online casino. Many online gambling venues offer both online casino games and sports betting for real money on a plethora of sports. Aside from the most popular like football, American football, basketball, and baseball, there are also sportsbooks that offer sports like horse racing, lacrosse, golf and as of recently E-sports too.

The best online gambling sites that offer sports betting too have a generous welcome bonus for new players. While this bonus type is different from the online casino one, it’s still generous and appealing enough to make you want to see if the odds are in your favor. The good thing about online British gambling sites that offer both online casino gambling and sports betting is that you can try both with the same account at the online casino in question.

Poker Sites

Online poker is perhaps one of the most played and most known casino games. There are several variants like Texas Hold ’em, Caribbean, and Video Poker, and they’re available in almost every online casino. Some casinos have a stellar selection of poker titles and casino games.


Roulette Sites

While Roulette isn’t the only game that each site has, their selection is stellar. All of the best online gambling sites offer a variety of games and that’s what makes players want to gamble online.

Blackjack Sites

Second in popularity only to Poker, Blackjack is another excellent real money casino game. The most popular of card games, Blackjack, and all of its variants are offered in just about any online casino however not all of them have as many Blackjack games as players would like.

Live Casino Sites

Nothing is quite like sitting in the comfort of your own home, yet still feeling like you’re in a brick-and-mortar casino. Live casino games have changed online gambling forever. Instead of the traditional way of playing card and table games, live dealer games add a little twist into the mix and make the whole gambling experience even better.

Slots Casino Sites

Out of all online casino games, the slots are perhaps the most preferred even in land-based casinos. The slots are quick, dynamic, and immersive types of games that have many variations and themes. They feature multipliers, special symbols like wild and scatter, bonus rounds with free spins, progressive jackpots, and even upwards of 1024 pay lines and it all boils down to what you prefer. As all the best gambling sites offer free spins as part of their welcome offer, it’s only natural that they have an extensive slots game selection.

How to choose the best UK online Casino

Choosing an online casino is a subjective thing as everyone has different ideas about what they want and need out of online gambling. However, given how many online gambling sites are out there, even knowing exactly what you want and need might still make it hard for you to choose where to gamble online.

There isn’t one formula on how to choose the right online casino, however, there are a few things you should take into account and separate the good gambling sites from the bad ones. Here are a few things we suggest you keep an eye out for.

License and Security

This should go without saying, but the license should always be the first thing you look for when you enter the online casino’s website. Usually, this information would be stated in fine print at the bottom of the site or you’ll easily spot the logo somewhere on the homepage of the site.

Playing a licensed online casino, from relevant and strict gambling authorities like the UKGC and the MGA, you can be sure that you are playing at a legal casino that is also safe. Should anything unpleasant happen or if you suspect foul play, you always have where to turn.

That’s why it’s always important to search for casinos that have valid and active licenses. In the case where you’re unclear of whether the license is valid, you can always check the site of the respective gambling authority as they usually have lists of revoked licenses as well as all of the licenses issued by them.

Aside from the license by a relevant gambling authority, it’s also important that the casino has taken all the safety measures to ensure that players’ personal information is secure. If the online gambling sites don’t have the standard 128-bit SSL encryption, you don’t really want to make a deposit and put your personal information at risk.

Online Gambling Security Organizations
UKGC The United Kingdom Gambling Commission is a respected authority that licenses and heavily regulates all gambling operators that offer services to UK residents.
MGA The Malta Gaming Authority (MGA) issues licenses to gambling sites within its jurisdiction. Operators must adhere to high standards of player protection in order to obtain and to keep their gambling license.
eCOGRA A trusted, independent testing and auditing authority. eCOGRA test and certify online gambling software. They test random number generators and analyze payouts to verify the integrity of gambling online games.
GLI A leading authority that provides RNG testing and audits of game results. They produce payout reports, detailing the actual payout percentages of real money games.
Government of Gibraltar A leading authority that provides RNG testing and audits of game results. They produce payout reports, detailing the actual payout percentages of real money games.
iTech Labs A leading authority that provides RNG testing and audits of game results. They produce payout reports, detailing the actual payout percentages of real money games.

Game Selection

The game selection and variety as well as the game developers should be other factors to keep in mind when choosing online casinos. Make sure to check if the casino has all of the games that you like to play whether that’s online poker, slots, table games, or variety. Online gambling sites in the UK offer sportsbooks in addition to the standard online casino games, so if you’re into sports betting too, you should look for those where you can play both with a single account.

The game developers are also an important factor, as some of them are very selective of the casinos that they collaborate with. Therefore, seeing that gaming industry giants collaborate with a certain casino, could mean that it’s a reliable and legit gambling site.

Welcome Bonus Offer and Other Promotions

Welcome bonuses are made to appeal to and attract new customers but at the same time, online casinos should also offer other types of bonuses to reward players’ loyalty. This is another thing that you should keep in mind when choosing your next online gambling site.

Aside from the lucrative welcome bonus that always makes players want to stay and play, see if the casino has other types of bonuses and rewards like a cash back bonus, refer a friend, loyalty reward, and daily/weekly/monthly bonuses.

Wagering requirements and Terms and Conditions

At first glance, the promotions page might look appealing and generous but seasoned players know that there’s more to it than that. Namely, online casinos place playthrough requirements on their bonuses so that they protect their investment, so to speak, and to make sure that players will not abuse them.

The wagering requirements can be as low as 1x and as high as 200x, depending on the online casino. This would mean that you would have to wager 200x the bonus amount you received, in order to withdraw your winnings. For high rollers, this may not be a problem, but for players who don’t want to overspend, it’s simply unfair.

There are the weighting requirements as well, meaning not all of the games count 100% towards your playthrough requirement. Slots usually account for 100% while some like table games and card games account for as low as 20% and sometimes they don’t even count at all.

All of this is stated in the terms and conditions page that every UK online gambling site has. That’s why it’s important to check the playthrough requirements and read through the terms and conditions thoroughly before you decide which are the best online gambling sites for you.

Payment Methods

When you are about to play at a gambling site, you’re anxious to start as soon as possible and you can only start as fast as your chosen payment method is. Same as with the game developers, payment providers are also selective about which casino they want to work with.

Some of the most popular payment methods, other than the standard credit and debit card, are PayPal, Trustly, PaySafeCard, Skrill, and Neteller to name a few. This is another factor to keep in mind when choosing the best gambling site as a lot is riding on the deposit and withdrawal methods. It’s also good to note that some casinos have made their bonuses unavailable to players who use certain types of payment methods for a deposit. That’s why we highly recommend you read through everything stated in the terms and conditions so that you can claim your bonus and start playing- hassle-free.


Depending on the type of games you prefer, you’ll experience long drought periods before you manage to win anything. Some casinos are open about the RTP of the games that they offer and some even hide it. But there are casinos that have had their overall fairness audited by an external body like eCogra. When a gambling site has been audited, you’ll notice eCogra’s logo on the casino’s website so be sure to stay on the lookout for that next time you’re on the lookout for a gambling site.

What safe online gambling sites are available?

All of the online casinos that we mentioned above are available for UK players who want to play at real money gambling websites. All online gambling sites that have a legal license from a credible gambling authority are safe to play at.

How do I know that an online casino is legit and safe?

The best way to tell that an online casino is legit and safe is by checking if they have a valid gambling license from a credible gambling authority.

Reading reviews on gambling websites is also a good way to protect your real money online.

How do I know that a casino is fair?

Just as online casinos are regulated by gambling authorities, so are the games by an independent agency. eCogra is a well-known one so you can be sure that a casino is fair if it has been audited by them and has its logo on the website.

Can I play all casino games on my mobile?

If a casino has a mobile-optimized website, you can play all of the games available through your browser. Mobile apps have a generally smaller selection than that of the online gambling site, however, with the increase of mobile gambling, more game developers are optimizing the games so you can play just about any game.
