The Winner – Play at the UK’s Top Online Casino!

On a daily basis, players are bombarded by countless ads from operators all claiming that they are the best online casino. At bestcasino.co.uk, we have taken the time to sift through the rubble to find you trustworthy and safe online casinos so that you can start playing worry-free.

On this site, you’ll also find a list of some of the other top online casinos in the United Kingdom as well as explanations of our criteria for testing operators. If you are looking for further recommendations, we strongly suggest checking out the best online casino on online-casinos.com. We also discuss welcome bonuses and their wagering requirements, which you’ll need to know about when you start playing.

The Characteristics of a UK Online Casino

Each provider recommended on this page is representative of the gold standard of what the UK has to offer when it comes to the best gambling sites UK. The operators are comparable in terms of their game selections, safety, accepted payment methods and RTPs. The following buttons show the different criteria we used for selecting the UK’s best online casinos. Feel free to click on any of the buttons below to delve further into your topic of choice.

In addition to the features above, this page discusses other topics that will be interesting for new online players, as well as for those who would like to improve their gaming experience through increased knowledge. Topics include info about table limits, history of the online casino industry, as well as some frequently asked questions. If you already know what games you like playing, you can jump to the section that recommends the perfect casino for the game you want to play.

How to Identify a Credible and Safe Online Casino

Player safety and protection is probably the most important aspect of any of the best casino sites. It is for that reason that licensing and security carries so much weight in our overall operator ratings.

In order to operate in the UK, a casino must possess a gambling licence from the UK Gambling Commission. These licences are not easy to get, and operators must display the ability to meet certain standards before they are granted one.

Every operator found on our site possesses a licence from the UKGC, so if you decide to play on one of the sites above, you can be certain that you are gaming at a safe online casino. The regulations, set out by the UKGC, are designed to keep operators transparent about their services, keep them socially responsible and to prevent underage gaming and money laundering.

If you do not find the UKGC logo prominently displayed on a casino website, stay clear of that site. The UKGC is a blanket organisation for gambling compliance, but there are also a few other things that make a casino safe.

IT security is one of the other important aspects of a trustworthy casino. It doesn’t matter how much fun the player experience is, if your money is not secure, then you shouldn’t be playing at that site. This is why all of the top online casinos take steps to encrypt sensitive information.

Many operators use SSL (Secure Sockets Layer) encryption protocol to protect your financial transactions, which means your data is safe at any of our listed best casino sites. In addition to data encryption, every casino game is subject to auditing by agencies that test the RNG (random number generators) and RTPs of every single game to ensure that the games are fair and do not rip players off. The main agencies that take care of this are eCOGRA (E-Commerce and Online Gaming Regulation and Assurance), TST (Technical Systems Testing) and GLI (Gaming Laboratories International), which are all recognised by the UKGC and are not affiliated with casinos so as to remain impartial.

Again, we would never recommend a non-trustworthy casino, and every site on our best online casino list is safe because of the three aspects above: licensing, encryption and regular auditing. If you would like to locate information about these on the casino’s website, all of the testing agencies are usually listed at the bottom of the webpage. There you are likely to find:

  1. The name and address of the company that runs the casino
  2. The logos of the responsible licensing agencies
  3. The operator’s current valid licence number(s)

We know you’re wondering, “but how can I be sure the casino isn’t lying to me about its licensing?” The good news is that you can prove the licence of the casino yourself, to make sure everything is legitimate. You just need to click on the UKGC logo on a website’s footer or click the casino’s licence number (it differs from site to site). You will then be directed to the operator’s licence, which will state if it is still active or not.

How Can You Check If a Gambling Licence is Legitimate
Locate licensing info on casino website:Image showing the footer of the betway casino website. A yellow circle is around the UK Gambling Commission Licence to highlight how to find it..
Verify validity of licence on UKGC website:Image showing the UK Gambling Commission licence of betway casino. There is a yellow circle around the word 'active' and the domain of the casino to show that the licence is still valid..

It is important to ensure that your operator of choice has a licence, but perhaps you are wondering why some websites hold licences from authorities in foreign countries and not just the UK. The next section will help to explain why this is often the case.

The Most Important Licensing Agencies in the UK

Now we cast our eyes towards some of the online gambling industry’s biggest regulators. Although licensing isn’t the most exciting aspect about the playing experience, it is the most important, and a basic understanding of some of the most important licensing agencies will help put any concerns about a casino’s legitimacy to rest.

The key locations for online gambling in Europe are the United Kingdom, Malta and Gibraltar. This is because these were some of the first countries in the EU to start regulating the online gambling market. As a result, licences from the UK Gambling Commission (UKGC), Malta Gaming Authority (MGA) and the Gibraltar Gambling Commissioner (GGC) are the gold standard when it comes to casino safety and trustworthiness. However, for UK punters, the most critical regulator is absolutely the UK Gambling Commission.

Up until 2014, most online casinos in the UK only needed a licence from an EU regulator such as the ones found in Gibraltar or Malta. However, with the introduction of the Gambling (Licensing & Advertising) Act of 2014, all remote gambling operators must hold a UKGC licence in order for UK punters to be able to use the site. The law is intended to add another layer of protection to keep UK players safe from nefarious activity.

The UKGC regulates operators and takes measures to prevent money laundering, underage gambling and to make sure that gambling sites adhere to the Commission’s technical standards in terms of fair games. Because of the UKGC, casino sites must also prominently display transparent terms and conditions, as well as publish the measures they take to protect your money. There is currently no law that regulates money protection, but it is best to look for a casino that keeps customers’ money in a separate account in case the company goes bust.

Some of the UKGC’s actions have included the placement of limitations on how the casino industry advertises, (nothing that overtly appeals to children) and the punishment of operators that do not adhere to the Commission’s standards. Operators who fail to comply face the possibility of huge fines. For example, the UKGC fined operator William Hill upwards of £6 million for failing to prevent money laundering. As you can see, even the most prominent operators are tightly regulated which ensures that players have a safe online casino experience.

You will often spot the Malta Gambling Authority (MGA) logo at some the best UK online casinos. Although some of you may be sceptical of a UK casino that isn’t based in the UK, we assure you that it is completely standard.

Many operators are based in Malta, even some of the most established sites such as BetVictor, due to the island’s trailblasing regulation of casinos, but mostly because of the country’s tax laws, which makes it an extremely attractive base of operations for casino companies. Not to mention, the MGA is located within the EU, which means that any business with a licence from Malta will be able to operate in all EU nations.

Because the UKGC has become the most important licenser in the UK, an MGA licence is not as vital, so don’t be alarmed if your casino doesn’t have one prominently displayed. However, if the operator is based in the Malta but is playable in the UK, it requires both a licence from the UKGC, and the MGA. In addition to licensing, the MGA publishes a handy list of fraudulent casinos that are to be avoided at all costs.

Gibraltar Gambling Commissioner

Gibraltar is similar to Malta in that its lower tax limits make it an ideal place for casinos to operate so that costs are low for both player and casino alike. So, a licence from Gibraltar is nothing to be sceptical about so long as the UKGC logo is sitting next to the Gibraltar logo on the gambling site of your choosing. If all of this is too much to worry about, you can choose one of the best casinos listed above to be certain that you are playing at a secure online casino.

It is important to remember that gambling legislation is constantly changing, and operators are now held to ever stricter standards (this is a great thing for player safety). The reasons the UK’s best casino sites choose to work from Malta and Gibraltar is because the economies of the two places are strongly supported by the casino industry, which makes it less likely that laws will shift overnight making once profitable websites no longer operable (although EU regulations would still apply).

Safe Casinos Verify Identities

Registration at any of the best UK online casino sites is extremely easy and completely free. Although it is important to keep your identity safe when online, you must use your real info when setting up an account. If you don’t, you will encounter problems once you want to withdraw any winnings following real money play. To ensure you don’t run into any issues, be ready to supply the following information upon registration:

UK casinos are legally obligated to verify IDs as a preventative measure against money laundering, so don’t be alarmed that the casino wants to know your name and address. As stated above, the best online casinos take the security of your personal data seriously. We suggest you avoid any casino that doesn’t ask for ID verification within the first 72 hours after making a deposit of funds. The UKGC requires that the company checks your ID or freezes your account if it can’t do so within the 72-hour time period. This is to ensure that no person under the legal gambling age can gamble at online casinos.

Why Identity Verification is Important:
  1. Registration Form

    The customer enters their data and can then deposit funds.

  2. ID verification

    Within the first 72 hours after creating an account, the casino must verify your account details with photo ID.

    Generic ID symbol
  3. Generic seal of approval

    Once your account details have been tested, all further payments will be approved.


This document from the UK Gambling Commission obligates casinos to verify the personal identity of customers.

One last reason casinos will want to know your address is to verify that you are playing in the UK. Each country has its own laws, and operators offer different bonuses based on the country, in which you are playing. If the casino finds out that you lied about your address, you will be forced to forfeit all of your winnings.

Good Casinos Help You Play Responsibly

Gambling can be a fun and rewarding when played responsibly. However, there is also a darker side to the activity, and the truth is that some players are at risk of becoming addicted, and this addiction can lead to many hardships. That is why it is important to find a casino that proudly displays its commitment to helping problem gamblers. The easiest way of doing that is to check the site’s partnerships with gambling responsibility organisations. All of the best casino sites, will also have the logos of responsible gambling organisations such as BeGambleAware.org, GamCare, GAMSTOP, the National Casino Forum and Gamblers Anonymous. These logos are usually clickable and will take you to the sites of the respective agencies where you can seek help or find literature about problem gambling (you will also find links to these agencies at the bottom of this page). You can find more information about the most recognisable institutions below.

Trustworthy casinos will provide access to tools and resources for at-risk punters. Most operators will have a ‘responsible gaming’ page on the casino site. This can usually be accessed from the footer of the webpage. Here you have access to tools that allow you to set limits to the amount you can deposit, the amount you can lose and the length of time you can play. If you really feel as though you are developing a problem, you can opt to exclude yourself from the site for a designated period of time, or forever, so that gambling there becomes impossible.

Trustworthy Casino Support

The final characteristic of a trustworthy casino site is that it should have a responsive and knowledgeable support staff that helps players with any problems that should arise on the site. Although casino technology has improved by leaps and bounds, you may still experience technical problems when playing. When it is money you are dealing with, you’ll want to make sure your issues are dealt with immediately. The casinos below have knowledgeable support staff that can also help clarify any confusing terms and conditions, help you with payments and explain game rules. Take a look at the chart below to see some of what support is available at the best casinos.

Casino: Hours of Operation: Contact Methods: Languages:
Mansion Casino 24/7 Live Chat Phone E-Mail English German

Betway Casino 24/7 Live Chat Phone E-Mail English German Finnish Swedish Norwegian Danish Spanish French Portuguese Russian
Grosvenor Casino 24/7 Live Chat Phone E-Mail English
888casino 24/7 Live Chat E-Mail English

As you can see, each of the above sites offers support in English, but some offer a handful of other languages. So, if you prefer to speak in your native tongue, you should consider an operator that provides support in your preferred language. We found that live-chat is usually the best form of support because it is often available 24/7.

Welcome Bonuses at the Best UK Online Casinos

Now that we are done learning about what makes an operator reputable, we can move on to the fun aspects of online casinos.

There are countless amounts of operators out there, and each is essentially selling the same thing: gambling. One way a casino tries to differentiate itself from the others, is to offer a welcome bonus that is unique to that operator. Pretty much every casino will offer some sort of bonus. These usually come in the form of free spins or percentage matches on your first deposit.

For some of the best online casino bonuses in the UK, you should check out our new online casinos page for a look at some of the fresh players on the scene. The casinos found there are not as well established as some of the bigger brands, but they do offer very interesting and creative welcome bonuses to entice new players.

Below, you’ll find one of the better casino welcome offers currently available. The operator will grant a cash bonus as well as free spins for a slot upon making your first real money deposit.

Casinos give you the option of declining to accept a welcome offer. You may ask, ‘why would anybody turn down free money?’ Well, it is because casinos don’t hand out free money for no reason. Most bonus offers come with some sort of wagering requirement that must be fulfilled before you get the money. It is important that you familiarise yourself with an operator’s terms and conditions before you accept the welcome bonus. Casinos are required to publish accurate information in the T&Cs, so pay close attention when reading. Once you understand the terms, you will have no issue withdrawing the cash after meeting the requirements. The next section will go further into detail on the things you should look out for when accepting a bonus.

Casino Bonus Requirements – Steps Before You Can Withdraw

Every single bonus offered by a casino will have terms and conditions attached to it. This section will delve into a few of the details about what sort of T&Cs you’ll find at the best UK casinos. Remember, each operator has different conditions for their bonuses. This only serves as a guide for what you should be on the lookout for. You should always read the full T&Cs of the website you decide to play at, because if you fail to accurately meet the requirements, you will forfeit the bonus offer. Here are the basics of what you should remember before accepting an offer:

As you can see, there are a few things to pay attention to. First, most casinos will match your first deposit amount (up to a certain limit). For example, if you deposit £100, you may get a £100 bonus and if you deposit £10 the casino will match that deposit. After making the deposits you’ll have to wager these funds. A standard requirement you’ll see is a 30x wager. This means that on a £100 deposit, you’ll have to bet £3,000 before receiving the bonus. Remember, most casinos will often use your real funds before the bonus funds. Which means, until your money is depleted from playing real money games, your playthroughs won’t count towards the welcome offer requirements. Other casinos only require you wager the deposit amount. You should also make sure if your chosen casino has given you a time limit, in which you must spend the bonus amount. Common time limits are 30-90 days; however, many casinos don’t place any time limits on the wagering requirements. In the end, it is better to think of welcome offers like a form of insurance, rather than free money. These offers provide players with an extra chance to win despite losing their original deposit.

Many casinos put limits on what types of games you can play when fulfilling wager requirements, and this info is usually found within the bonus T&Cs under ‘wagering contribution’. It is standard that slots will contribute 100% towards wagering requirements, and many card games will only count 10-25% (or not at all) of your bet towards the final amount. Perhaps it is best to avoid a welcome offer if you don’t play slot games. Although some casinos do offer live casino welcome bonuses, which are great for players who like card games.

In conclusion, welcome offers are more suited to the type of gamer who knows he or she will be playing a lot. If you fall into the casual gamer category, you can always decline the welcome bonus, and play like you would at any other casino. Anyway, most of the best online casinos offer other promotions that you’ll be able to participate in, once you’re a member.

Other Types of Bonuses at Top Online Casinos

If you decide to stay at site, although you don’t want to participate in a deposit bonus, you’ll be happy to learn that most operators offer their players additional types of bonuses. Often, you will find some form of a loyalty or VIP scheme, with which you gather points that are redeemable for cash or free spin bonus offers. In addition, casinos constantly update the promotions on their websites. It is very common to find daily, weekly and monthly offers and promotions. If want to add a little spice to your gaming experience, you might also want to participate in flash tournaments, which are becoming more and more common these days.

If you’re extremely lucky the best online casino sites will offer players a no-deposit bonus. These offers are the equivalent of free cash, and as you can expect, they are extremely rare. If they aren’t in cash form, they will usually be in the form of free spins for specific games. 888casino offers new users an £88 no-deposit bonus, so that they can try games risk free. Many no-deposit bonuses also have wagering requirements, so the casino’s terms will apply to these offers as well

What You Need to Know About Online Casino Games

There is probably nothing that impacts the overall player experience at an online casino than the games selection. After all is said in done, you’ll spend most of your time playing games. If you’re an experienced gamer, you probably already know what casino games you like to play. However, beginners should look for a few things before playing for real money. The next sections cover return-to-player rates, table limits, providers and types games. These factors can make or break your overall experience when gambling online.

Look for the High Return to Player Rates

The return to player rate (RTP) is one of the most important things to consider when playing a game. The percentage shows how much a player should expect to see returned when playing a game over an extended period of time. The higher the RTP is, the lower the house edge is. If you look at the numbers below, you’ll notice that there is a wide variance in different RTPs. Those numbers are averages, and the individual games within each category will also have different RTPs. The RTPs listed below are obviously the result of many rounds of play. RTPs can appear deviate a lot in the short term. Sometimes you may lose all your money, and sometimes you may win big – it’s up to chance. However, RTPs, in reality, never change, and will always equal the designated amount over a long period of time.

Slots and games of chance tend to have slightly lower RTPs but should fall in the 94-98% range. The best percentages are found in blackjack and other card games. This is because card games are more strategic, and less luck based. The games at our top online casinos all have RTPs in the mid to high nineties, and as previously stated, the games are tested by independent third-party auditors, which ensure that all games pay fairly.

To Compare: Slot RTPs in land-based casinos tend to be lower than those found at online casinos. This is because of the higher costs of operating a brick and mortar casino.

  10. 96.00% RTP ⮞ Gonzo’s Quest by NetEnt (Highest Payout Slot at Mr Green Casino

Table Limits That Suit You

One of the major benefits of online casinos is that they offer suitable bet and table limits for every type of player. Land-based casinos often place minimum bet limits that can be too high for the more casual player (new laws will place a max bet limit on fixed odds betting terminals, however). At any of the top casino sites you’ll find slots that allow you to bet as little as 2p on a spin, and card games that allow 10p bets per hand. This is perfect for those casual gamers, or for those who would like to familiarise themselves with a game before they start wagering larger amounts.

Software Providers and Their Strengths

It seems pretty obvious, but you should know that the games you find on a gambling site are not made by the casino operator. There are hundreds of software developers who produce the fun and unique games that casinos fill their libraries with. Some focus on one corner of the market, while others produce many types of games. If you’ve played online before, chances are you have run into games made by Microgaming, Playtech or NetEnt. These three companies represent the largest names in the casino software provider industry, and they have produced hundreds of the most popular slot, table and live games available on the web. That being said, there are tonnes of smaller game producers who have begun challenging these larger companies. Look below to learn about some of the smaller companies and see why their fun and exciting games have been winning industry awards left and right.

Exciting New Developers on the Rise

Award Winning Universe

ELK Studios has developed its own universe of characters. You’ll notice ELK Studios’ personalities spread out across award-winning games like the Wild Toro slot and Wild Seas. Crossover titles mean that these characters also appear in each other’s games.

Boundary Pushing Games

Compared to giants like Microgaming, Play’n GO’s games library is relatively small. However, where the company lacks in quantity, they more than make up for in creativity. Games like Viking Runcraft challenge our idea of what slots can be.

Beautiful Graphics

Yggdrasil is one of the newest faces on the software scene, but it has been making waves in the industry due to its beautiully animated slots. As a result the software developer has won the EGR Slots Provider of the Year Award in 2016 and 2017.

Creative Bonus Games

Thunderkick has been developing many fun games over the last few years. Every single slot they have released is stunning and exciting with creative bonus features that are not available everywhere. Keep an eye out for sticky wilds and transforming symbols

Keep an eye on what software providers your casino of choice offers. Any great online gambling site will offer a large selection of high-quality games from multiple providers. With our top casino sites, you’ll have access to a wide selection of games, with exciting bonus features, smooth graphics and jackpot opportunities.

Games Found at the Best Online Casinos

There is simply no comparison between land-based casinos and their online rivals. When it comes to the number of games a casino can offer, online sites win without question. It is common to find hundreds or even more than a thousand, different casino games at any of the aforementioned best online casinos. However, it isn’t just quantity you should look for, a great operator should also offer a wide range of casino games including card games, live games and slots. Software developers are constantly releasing new games, and my top casino sites regularly update their game libraries to keep things fresh for their users.

Slots – The Backbone of Casinos

Without question, slots are the most popular games at casinos and, chances are, the first time you ever gambled, it was on a slot machine. Perhaps the popularity of the casino classic is due to the possibility that a small wager can lead to a huge payout (especially with a jackpot slot). Whatever the reason, because of the extreme popularity of the game style, operators continue to stuff their games libraries with hundreds of fun cutting-edge slot titles with high payout rates. Recent trends have seen a growth in 3D slot games as well as games that utilise social-media to add an exhilarating and competitive element to gaming.

Some of the Best Slot Games

At the UK’s best online casinos, you will find many popular titles, from the industry’s top developers, like NetEnt’s Gonzo’s Quest and Playtech’s Gladiator. Below you’ll find my choice for the current best casino to play slot games at.

The top sites will also have a handful of progressive jackpots such as Mega Moolah, a slot that holds the record for the largest online jackpot payout with a sum of over £16 million. Jackpot games are often linked across multiple providers, which means that these games have the best online casino payouts of all games.

Blackjack – Countless Variants

The best thing about blackjack online, is that you have a wide range of special variants that are only available at online casinos. Although all games follow the basic ‘21’ rules, the games found at the top casinos allow for a wide range of side bets, that, when won, can lead to some massive payouts. Blackjack technology continues to develop, with ground-breaking games like Sonya Blackjack from Yggdrasil. Check out my dedicated page if you would like to know more info about online blackjack, and its numerous variants.

It has a great mixture of live and video versions of the classic game and its many variants.

Roulette – Timeless Classic

Roulette is another extremely popular table game. In the past, online versions of roulette have left much to be desired in terms of atmosphere. Advances in graphics as well as live-gaming technology have brought the online version of the game back to life. Playing online has its advantages because you are under no time pressure when considering your betting strategies. The computer dealer won’t roll the ball until you press ‘bet’. Below you’ll find my favourite operator at which to play roulette. Its selection of games has few rivals.

Although poker is perhaps not the most popular game at online casinos, it does still have its ardent supporters. Although, many enthusiasts have chosen to go to dedicated poker websites, which allow you to play head-to-head against other punters, some operators still offer a decent selection of games to those who like to play the card game every once and a while.

Probably the two best live gaming companies are Evolution Gaming and Playtech. If a gambling site has live games from either of these two companies, I can confidently say that you are playing the best live table games available online.

Live Blackjack

There are many reasons to play blackjack at live casinos. However, anyone new to the live casino world may have a few questions about what to expect. If you’re curious about exploring the topic further, head on over to my live blackjack page. There you will find explanations of the various features of the game when played in its live format.

Up until recently, casino apps were extremely popular and just above, you will find the best options for downloadable mobile casino apps. However, it has become increasingly easier to play casino games directly in your mobile browser. All of the best UK casino sites have extremely smooth and useable mobile websites. It is no longer necessary to download an app, and waste valuable storage on your device.

When playing on the go, you’ll find all of your favourite games from all of the industry’s best developers. You’ll have no trouble finding progressive jackpot slots, blackjack and other games on a mobile gambling site. The only games you won’t be able to play directly in the browser are some very old flash-based games. Although many are still playable.

PayPal and Other Payment Methods

No matter which site you choose, if you want to gamble for real money, you are going to need to deposit money. And if you’re lucky enough to win, you’ll want to withdraw that money. For these reasons, it is vital to find a casino with payment methods suitable to your needs. Like bonuses, payments also have their own set of terms and conditions. Pay close attention so that you don’t run into any problems when it is too late.

All of the best casino sites will accept a wide array of deposit methods including debit cards, bank transfer, e-wallets like Skrill, Neteller and more. However, not all of these methods are suitable for withdrawal. For example, paysafecard is great for deposits, but almost no site I’ve seen will make payouts to prepaid cards. These conditions also apply to welcome bonuses. I have come across some sites, at which players will not qualify for a welcome offer if they deposit funds using the wrong method. However, in recent years, online casino payments have become streamlined and largely hassle-free.

Instant Payments with

  • Additional payment methods:VISA Mastercard Skrill paysafecard

  • Quick and secure payments
  • Massive games library

£500 Bonus

Play Here!

Full T&Cs apply. *New customers only. Min deposit £20 max bonus amount £500. First deposit: 100% up to £200. Second deposit: 50% up to £300. Wagering 40x for each bonus. Game weighting applies. Cashback: 5% cashback on first and all other deposits during week 1, 10% cashback on all additional deposits taking place in week 2 only. Bonus betting limits: slots - $/£/€5 all other games – 10% of bonus amount

Perhaps the easiest and most straightforward payment method is the popular e-wallet PayPal. The payment method is not only easy, but due to the protection PayPal offers its users, most safe and trustworthy casinos will accept deposits and withdrawals with PayPal. One added benefit is that with PayPal, you don’t need to worry about sharing your bank details with the website, simply use the email and password connected to your PayPal account.

Each method of payment is subject to some sort of fee, but this is usually taken care of by the casino site. However, you may occasionally come across an operator that charges for certain deposit methods. As a result of these fees, operators usually have a minimum deposit limit of around £10 so that the fees that they cover aren’t more expensive than the actual deposit.

The processing time of a transaction depends heavily on your payment method. It is standard for deposits to be instant, but keep in mind that withdrawals will usually take a few days to ensure the money ends up in the right hands.

Summary: Casino payments are subject to their own conditions set by the individual casino, so before making a payment, I suggest you look at the bonus conditions, transfer times and possible fees associated with your chosen payment method.

The Future

It appears that the future of online gambling will utilise new technologies like virtual and augmented reality. In addition, we are starting to notice a growth in the use of cryptocurrencies, like BitCoin, throughout the industry. Regulations continue to develop with the aim to increase player safety and security.

The most significant moment for internet gambling came in 1994 when Microgaming released its first online casino software. The first online provider was InterCasino, which had 18 different games at the time. Once the EU started to regulate online gambling the industry truly started to grow. The British Crown would later regulate gaming in the best real money casinos. Since then, more and more players are turning towards the net to have fun.

Frequently Asked Questions

As you can see from the breadth of topics we have covered on this site, there are numerous different aspects to the world of online gaming. We have done our best to discuss the topics that UK players find most important, but in reality, it is impossible to cover everything. If you would like to know more, feel free to write to info@bestcasino.co.uk. Some of the most common questions sent to us by are readers are the following:

✅ What is the smallest amount that I can bet when playing a casino game?

The advantage that online casinos offer over their land-based counterparts, is that they allow players to spend a wider range of limits. Many brick and mortar casinos put minimum limits on their slot and table games that are much higher than the limits for online casino games. At some of the best gambling sites, players can wager as little as 10p on a hand of blackjack.

✅ Is it possible to try online casino games for free?

Yes, in fact, we recommend that you try out a game for free before you spend your real money gambling. Many operators allow players to play slots or table games in a ‘free play’ mode. This is a great way to get accustomed to a games features and rules without risking real cash on a game you don’t fully understand. If the casino doesn’t allow you to try a demo game, try looking at a software developer’s website. Most of these sites have casino games available for free play. Unfortunately, you cannot try live dealer games for free. If you want to learn to play a table game, I suggest you try a video version.

✅ Is registering at an online casino free?

Registration at any reputable casino site is completely free. Never play at a site that asks you for funds while setting up an account. The only time you need to deposit funds, is if you want to start playing for real money, or if you would like to accept a casino’s deposit welcome offer.

✅ Are online casinos legit?

Any casino you find on this site is completely legit, because it holds a valid UK Gambling Commission licence. These ensure that the casinos pay fairly and protect players. However, there are many fake casinos out there, so it is important to check if the site you play at has a gambling licence. Click here to find out how to do this.

✅ Which online casino pays the best?

There is no online casino that pays more than another. Payment amounts depend on your bet size as well as the game you are playing. The payment of a game is set by the developer of the game and has nothing to do with the casino, at which you are playing.

✅ Can you win money on online casinos?

Yes, you are able to win real money at online casinos as long as you deposit real money before you play. Any bet made with real money will pay in real money.

✅ Can you play slots online for real money?

Yes, in fact, slots are the most popular real money online casino games.

✅ Which online slot machines pay the best?

Almost all slot games have return to player percentages in the mid 90s. This means that most games have a similar payout rate. However, if you’re looking for the biggest payouts, you should play huge progressive jackpot games like Mega Moolah or Mega Millions.

✅ Which online casinos have the best payouts?

Game payouts have nothing to do with the casino, at which you play. The amount a game pays is set by the individual software developer of each casino game. All of the top 10 casinos above have high return to player rates in the mid to upper 90s.
