The Top 20 Best Online Casinos for 2021 by Category

Each of our top 20 online casinos for 2021 excels in a certain department. This is understandable, as the competition in the online casino industry is getting fiercer by the day, and standing out from the crowd with something special and unique is a must. We made sure to find and rate the biggest strengths of the top 20 casinos UK in a comprehensive rank list. Certainly, the information below will assist you greatly in clarifying what your best options are in each category. Without further ado, here are the shortlisted winners:

The top UK online casino sites are divided into categories that are based on the detailed criteria behind our rating process. All of the operators have particular pros and cons, and we tried to capitalise on their robust features. For instance, no deposit deals are sporadic, and we had to do a lot of research to find the best no deposit casino for UK players. Meanwhile, in other categories such as the best games, the competition is much higher. Thus, the sifting process required much more additional testing to determine the best operator from the list of the top 20 best casino sites in each gaming category – blackjack, slots, and roulette.

The Criteria Behind the Top 20 UK Casinos

Now, let’s elaborate on the criteria we use to evaluate each top UK casino site. We’ve broken down the process into a few main categories – games, payouts, bonuses, software, payment, and safety. All of the abovementioned classifications are an invaluable part of the overall assessment when ranking something as important as the top 20 UK casinos. They are often the make-or-break foundation, and we must say that the competition is vigorous. We take into consideration not only the quantity but the quality as well because in our opinion they go hand in hand – and of course, we subject all new casino sites to the same evaluation process.

For instance, many internet casino games don’t necessarily mean that they are of high quality or suit all kinds of British players. For some players less is more, as fewer games could be a good thing if they suit both low-stake and high-rollers alike. Others count on diversity and want to have access to as many gambling games as possible, letting quality take a back seat. The same rule of thumb applies to the rest of the leading criteria, and we strictly follow it till the very end of the best online UK casinos list. To help you find your way around, we have provided a quick-link navigation menu that will help you find the top UK casino website that is best for you.

As you can see, the list of available games at the best UK online casino is quite long. There’s virtually no limit on the varieties and types of real money casino games. British customers are some of the pickiest when it comes to having multiple options and premium quality, but the top 20 best UK casino sites step up to the challenge. The players love slots, blackjack, and roulette quite a bit, but frankly, that’s not surprising at all. Those three types of casino entertainment are among the most popular anywhere in the world. However, not all operators from the best UK online casino sites have the full arsenal of playing options at their disposal. That’s why further down, we’ll take a look at each game type individually alongside our suggestions for the top online casino sites.

Online Slots for UK Players

In the last 20 years, online slots have become an indispensable part of the top 20 best UK casino sites and so did extra spins bonuses. Their wild and unpredictable nature attracts players from the UK who love to count on lady luck alone, without being able to influence the outcome. Unique features, entertaining themes, and eye-pleasing graphics are just a few of the reasons why punters love slot machines. And let’s not forget the simplicity of playing slot games. There aren’t any skills or extra knowledge required, you just press the Spin button and hope for the best. Whatever the reason behind your decision to enjoy playing slots, here are the best operators from our top 20 online casinos UK:

Among our top 20 best UK casinos, we pinpointed 5, which we believe to be the best in terms of online slot selection. They offer hundreds of the most played slots, including some of the best online slot games. In order to justify our decision, we took into consideration their payouts as well as the total number and the diversity of software providers. The higher the average return-to-player percentage, the bigger your chance of securing a profit. Of course, having the latest and hottest titles in their libraries is a must for the best UK casino online.

And what better way to kick-start your real money journey than free spins? Yes, that’s also a critical indicator that determined our final choice. All of the selected British online casinos will give you the opportunity to grab a wonderful first deposit bonus and some free spins. Our selected top online casinos will treat you with literally hundreds of the best online slots on the market. Moreover, if you fancy a progressive jackpot, you’re exactly at the right place!

Online Blackjack and Roulette

While slot machines rely solely on a random number generator (RNG), the table games have a little more skill involved. Being able to strategise your move is something that many enjoy on British casino sites. Blackjack, in particular, has been on the profitable side of the coin for skilled players who can count cards. On top of that, it is known to be the game with the lowest possible house edge.

Meanwhile, roulette is the most recognisible game of chance not just in the top 20 casino sites in the UK but worldwide. All the more that is true for Evolution Gaming’s Lightning Roulette. Debates are often being held about the best online casinos roulette winning strategy. But truth be told, having good fortune is always a vital part when playing roulette, and in fact, any other game of chance. Here are the best-performing ones of the top 20 casino sites, based on the blackjack and roulette game selections:

The sheer number of roulette and blackjack games didn’t cut it to this rank list. Our criteria for top internet venues for those table games is more about the limits and game diversity at casinos in the UK. While having 20 table games instead of 2 is much better, a wide variety of table limits is much more important to us. Another major factor is being able to play live blackjack and roulette variations. Besides, having a generous welcome bonus is always a nice benefit when you want to test your skills at the best roulette games and top blackjack types. Good first deposit bonus offers can help you play more game variations for a longer period of time.

We somewhat presumed that you might be familiar with the terminology behind house edge. In case you’re not, we have a thorough payout guide for UK players, where you can learn more about the topic and how it affects casino payouts. In a nutshell, the RTP percentage varies greatly from game to game and the total number of spins. While this is an excellent indicator to orientate yourself of a possible advantage over the best UK online casinos, you shouldn’t rely entirely on it. As we said, determining the payout rate is done by authorised audit agencies and is based on thousands of spins – all best casino online slots need to pass such inspections before obtaining a license from the UK Gambling Commission.

Welcome Bonus Offers & Other Online Casino Promotions

It’s not uncommon for players to face difficulties with the bonus wagering conditions. While many UK punters are well familiar with how to turn best UK casino bonuses to good account, others are not as resourceful. For what is worth, we advise you to keep your eyes peeled at the T&C. Impossible wagering conditions will make your casino payouts impossible or hinder them in a big way. Another thing to consider is multi-deposit package deals that grant you second and third deposit bonuses. These promotions are really great for British gamblers who are regular at the online casinos.

The Bonus Wagering Requirements

Along the same line of thought, there’s an additional criterion based on the casino bonus wagering terms. Experienced UK players pay special attention to the playthrough requirements as they are well aware that without fulfilling them, the bonus will be forfeit. And you definitely don’t want that happening to you. Always make sure to get acquinted with the full terms and conditions of a particular first deposit bonus or other kind of pormotions before signing up for it. Playing with the casino’s money is one of the best advantages that online operators hold to their land-based counterparts. As a rule of thumb, it is best if you can find bonuses with low or no wagering conditions and remember to gamble responsibly. With that being said have a look at the best low wagering bonus offers from our top-rated UK casinos online:

In case it’s not clear by now, the lower the turnover conditions, the better for you. And as we already mentioned, keep in mind that most of the welcome bonus offers and other promotions come with an expiry date as well. If you fail to claim your offer until the end of the 30 days validation period, you’ll lose it plus any profit made along the way. That’s why it is best to have a game plan and follow it without failing to gamble responsibly.

After all, the software is what makes up a game, regardless of game types. The quality of the gaming provider is what separates average casino platforms from fast and intuitive ones. Many British players pay extra attention to the live and mobile platforms as well, so all games must work flawlessly on both the desktop and mobile versions.

Live Casino: Real-Dealer Games & Platform Quality

The quality of the live lobby takes a central stage when we talk about real dealer gamification. It’s not a surprise that many UK gamblers prefer playing online casino games against professional dealers. Ever since the progress of live broadcast, this type of gambling has been attracting players who are fond of playing against real croupiers. The absence of lag and high table limits are the main qualities when shopping for live dealer games. Let’s take a look at the best live UK online casino site from our recommended top 20 operators.

Essentially, each live table game is led by a professional croupier who accepts the bets of casino players within a specific time frame. The dealers usually are both men and women, but some casino operators rely on the presence of more female dealers. Typically, the croupiers are very attractive and friendly. They will greet you when you enter the game lobby and you can interact with them through the live chat option available at most of the best UK online casinos. Most commonly, punters have a countdown of 20-30 seconds to lay their bets between each round.

While there’s no limit to how many people can participate in live roulette at the same time, live blackjack tables work similarly to land-based counterparts. This means that if the total number of, let’s say, 8 seats are occupied, then you have to wait in the lobby. But that’s rarely an issue because the top 20 online casinos UK have dozens of high-quality live casino games, and you can always find a free spot. Most of the top UK casino sites offer the ‘bet behind’ option, to better the player experience for those who can’t find an open seat.

Performance of Mobile Casinos

In 2021 playing on the go is no longer a lux, but a necessity for UK punters. The premium operators cannot afford to neglect their platforms so they built them mobile-first. It’s an essential requirement that the online casinos offer seamless access to Android and iOS users alike. Thus, we’ve only listed the candidates that tick all boxes. Also, we took into consideration the total number of mobile games available, how quickly they load, and how often they crash. You definitely don’t want to be on a winning streak and experience a freeze or another error. Let’s explore the top casino apps from our approved list:

After we tested each of the top 20 UK online casinos on Android and iOS devices, we considered the shortlisted candidates the top options. Having a dedicated mobile app is also a plus, but not as vital. Overall, the browser versions are just as handy for the casino players, and they don’t require additional space on your smart device. Another perk of a casino app is that it allows you to use even more safe and secure payment methods, which are only available on your cell phone. If you want to learn more on the topic, check out our dedicated page about the best casino apps for UK players. There, you will find a casino guide to the best mobile online casino operator, along with some tips and interesting informaiton about gambling on the go.

Still, PayPal is king when it comes to the most popular casino payment method for British players. Although the competition from Skrill and Neteller is vigorous, its great reputation makes it a preferred banking method, unlike bank transfers. The fast speed of a real money deposit and the high level of security is enough reasons for millions of customers to trust the popular e-wallet. Luckily, there is a large number of trusted PayPal casinos to choose from.

And with the advancement of blockchain technology, the competition becomes even more vicious. What cryptocurrencies bring to the table in terms of speed and low-cost transactions, make them a nice addition to the list of payment methods of the top real money online casinos. While still not as popular, Bitcoin and Ethereum are expected to forge ahead soon and enjoy worldwide adoption, much to the delight of online casino players

Online Casino Safety – UK Licensing and Audits

Usually, you can find all of the above information on the footer of the best UK online casinos. If you see the logos of agencies such as eCOGRA, GamCare, and GambleAware, that’s a clear sign that the operator is reliable. Since the gambling laws in the United Kingdom are stringent, the best casino sites take serious measures to prevent irresponsible gambling from their customers. You can get help from multiple organisations whenever you feel like real money gaming is getting the better of you. Of course, our team also supports this cause fully, and we’re encouraging you to stop playing when it stops being fun.

While on the same train of thought, we must also mention the importance of cybersecurity when playing with real money on the Internet. We make sure that the recommended top 20 online casinos UK utilise the latest SSL encryption fully. Companies such as DigiCert are one of the industry leaders when it comes to cybersecurity. Furthermore, reliable customer support is also a must for the top UK casino sites. Every little form of gratitude towards the customers sticks with them and builds stronger relationships. That’s why even the smallest details count in the online gaming industry.
