Common Features for The Top 20 Best Online Casinos

Among the top 20 casinos, not just any average site makes the cut. So, what do these top-notch 20 casinos have in common that sets them apart and makes them better than others? Here, we will go through all the features that are found in the cream of the crop of casinos.

📜 Licensing

Licensing is a cornerstone for any casino aiming to be among the best. A licence is not just a guarantee of reliability; it promises that the casino is accountable to an authority that can, if necessary, penalise the casino for any rule violations.

Of course, there are differences in licences as well. Some licensors are considered the best in the industry, such as the UK Gambling Commission (UKGC) and the Malta Gaming Authority (MGA), while others may not uphold standards as rigorously.

For an online casino to legally market itself in the United Kingdom, it must be licensed by the UKGC. This regulatory body is known for its stringent rules and the top 20 casinos naturally meet the requirements set by the licence.

💷 Payment options

Payment options play a crucial role when people are seeking the best online casinos.

The top casinos take into consideration the location of their users when selecting payment methods for their sites. However, this alone is not sufficient; the casino must also think about creating a payment method selection that can cater to the broadest possible user base.

In addition to credit cards, you may encounter the following payment methods at top casinos:

Google Pay

Many finest casinos offer Google Pay deposits

Google Pay is an easy and convenient e-wallet, and you might already know who developed it (hint: it's Google). Google Pay was first launched in 2015, initially under the name Android Pay. With Google Pay, you can store multiple card details in the service and choose which card to use when making payments.

Using Google Pay means you never have to worry about sharing your card details with the casino, as you use your Google Pay credentials for deposits. Unfortunately, Google Pay can only be used for deposits as it does not support withdrawals. Therefore, for withdrawals, you must use another method.

You can check out the full list of Google Pay casino sites where you can use this payment option.


Best UK casinos often support Neteller payments

Neteller is one of the most popular e-wallet services, and on online casinos, it is one of the most common payment methods. It supports up to 26 currencies and over 40 different payment options for transferring money to your wallet. To use Neteller, you need to register an account with the service, choose a payment method, and then select Neteller as your payment option when depositing.

Neteller can be used for both deposits and withdrawals. Its only significant drawback is that many casinos have prohibited claiming bonuses using Neteller. For this reason, if you want to take advantage of the casino's welcome bonus, Neteller may not be your first choice for deposits.

See a handy list of all online casinos that accept Neteller.


Trustly is a payment method often seen on top casinos

Trustly is a payment system with its roots in Sweden, and it has since expanded its usage to over 30 market areas globally.

Trustly arrived in the UK in 2016, but it's only recently that it has become more widespread on online casinos. Using Trustly on a casino is extremely straightforward; simply select Trustly as your deposit method, then choose your bank and specify the amount you want to deposit. Approve the deposit through your bank, and you're ready to play.

Trustly can be used for both deposits and withdrawals. An advantage of Trustly is that it does not impose any fees on transfers. If transfer fees are mentioned on the casino's cashier, it is a service charge added by the casino itself.

💰 Bonus Offering

There are various bonus offerings available among the top 20 online casinos. Especially concerning first deposit bonuses, the offerings vary between bonus money and spins, and no first deposit bonus UK promotion is exactly the same as another.

The highest-quality online casinos are fair throughout their first deposit bonuses, reflected in aspects such as low deposit limits and reasonable wagering requirements.

No deposit bonuses are highly favoured by players. Sadly, they have become increasingly rare even on the best casino platforms. No deposit bonuses in the UK have been on a decline year by year. Fortunately, they are such a significant asset for casinos in strengthening their brand that no deposit bonuses will undoubtedly continue to be seen in the future. Free bonuses, after all, provide players with a practically risk-free way to try out a casino.

In addition to free bonus money, equally popular bonus offers are free spins which allow you to play some of the casino games completely for free and still win real money. In the UK no deposit free spins are almost as rare as cash bonuses but, among no deposit bonuses, free spins are the most common form.

🎰 Selection of Different Games

The games on top 20 UK online casinos is diverse

On the best-ranked casinos, game selection is one of the most important features. The top 20 casinos can showcase nearly 100 game studios and thousands of options to play. This begs the question, who would even want to play on a casino that offers only a few dozen games from a single provider?

Naturally, quality should not be replaced by quantity. The best casino selects the most interesting and reputable game developers and passes any B-list manufacturers. For example, on the highest-rated casinos, you'll almost always see games from NetEnt, Microgaming, Yggdrasil, Playtech, and Pragmatic Play, which are all considered top-shelf game developers.

Live Casino Games

For the best UK live casinos, the finest gambling sites most usually choose Evolution and Pragmatic as their live dealer developers. These two live casino studios can provide casinos with high-quality live-stream games covering everything from your classic table games to smashing game shows.

Online Slots

Slots are the heart of many casinos, and this is true on online casinos as well. The top-tier casinos also carefully select the developers of slot games and make their choices only from properly licensed ones.

On most casinos, you can find a curated list of top slots, which often include popular titles such as Starburst, Book of Dead, Dead or Alive, Big Bass Splash, and Bonanza Megaways.

Table Games

Table games are the cornerstone of every self-respecting casino. Particularly, a casino that offers a good selection of blackjack and roulette tables is sure to stand out.

The best online blackjack sites can list dozens of different versions in their game lobby, delighting fans of these classic games. Similarly, the best online roulette sites go beyond just offering American roulette, providing a diverse range of options.

🛎️ Customer Support

Good customer support is extremely important for online casinos because it directly interacts with the player.

Players most often contact the casino's customer service in case of issues or when they want to inquire about the status of withdrawals. This can happen at any time, as casinos and their games are open 24 hours a day. Therefore, the 20 finest casinos strive to provide customer support around the clock or, at least, during peak hours.

The top casinos offer customer support on multiple different channels, such as live chat, email, contact form, phone, and social media.

💸 Level of Payouts

The level of payouts significantly influences the attention a casino gathers from both players and Bojoko's experts. Naturally, the 20 top-rated casinos have a high payout percentage.

The casino's overall payout percentage is typically calculated based on the Return To Player (RTP) of its offered games. In many cases, the math is done based especially on slots with the highest RTP. The result indicates how much the casino theoretically pays out as winnings from all money wagered on games.

By adjusting the RTP, the casino can affect its margins; if the RTP is high and the casino's margins are low, the players have better chances to get bigger payouts.

There is also the casino RTP that you may want to see. It is the combined value of all the games. It doesn't immediately tell you which are the best online casinos that payout the most, but it gives you an idea of what the general RTP level is.

💭 User Experience

User experience is at least as important a feature in a casino as bonuses and games. If a casino is difficult to use or slow to load, why would anyone want to waste their time on such a site?

The sites listed among the top 20 casinos have optimised their platforms to function seamlessly on all devices, and there's no need to wait for the games to load. It's also easy to find desired games on the casinos since the game lobbies are organised in a way that makes them intuitive to use.

📢 Casino's Reputation

Reputation is practically vital for every online casino. The reputation of an online casino is largely influenced by all the previously mentioned features, from bonus terms to user experience.

If a casino has unfair bonuses, rude customer service, and/or games with poor payout rates, word spreads quickly from player to player. A casino with a bad reputation usually doesn't last long, and comparison sites like Bojoko play a part in ensuring that.

A good reputation is indeed one of the major factors that unite all the top 20 online casinos listed on this page.

Safety & Security

A safe online casino in the UK is characterised by having a license from a reputable gambling authority. Regulation alone isn't enough, however.

Casinos must ensure personal and financial information security through protocols like SSL encryption. They should guarantee fair play with random number generators (RNGs) and promote responsible gaming by providing related tools and resources. Additionally, regular audits by independent bodies are essential to maintain compliance with safety standards. We have a page dedicated to finding secure online casinos; be sure to check that out.


These casinos are far from mediocre sites and provide you with the best possible overall experience.

The top 20 online casinos represent the elite group of casino sites.

On the best online casinos in the UK, you can easily engage both on your computer and mobile device, receiving high-quality customer service when needed. The game selection is curated with care and prioritises quality, and the available deposit methods are secure and swift.

If you want only the best from your casino and want to ensure that your chosen casino is not only reputable but also safe, consider selecting your next casino from one of these top 20 sites.
