Best online casinos by category

If you are looking for a gambling site with particular strengths or unique selling points, you will find my personal favorites for the most important categories here.

Bwin Slots - Our recommendation for slots

Bwin offers one of the most varied slot lobbies on the market in United Kingdom with over 1,340+ slots. In addition to games from Pragmatic Play and Play'n GO, there are exclusive titles such as “Resurrecting Riches” and “Bwin Rush” that cannot be found anywhere else.

Merkur Slots - Most Merkur slot machines

Who has the most Merkur machines? Surprise, it's the original itself. The makers at Gauselmann list 125 titles here, from El Torero to modern versions. But there is more, because what is special are definitely the exclusive Merkur Multi Slots. Titles like Eye of Horus use a two-account system to start game rounds without waiting after a win. You can hardly get more of a German arcade feeling online.

• Largest selection of Merkur games with 125 titles, directly from the manufacturer.
• Exclusive multi-slots with two-account system for rounds without waiting.
• The seriousness and tradition of the German Gauselmann Group in the background.
• Despite the name, there is also a large selection of games from other manufacturers.

• The name and focus could turn off players who prefer other developers.

Novoline - With Novoline slot machines

While other providers only have Novomatic and Greentube games in their portfolio, Novoline is all about these titles because all three brands belong together. Greentube is the online division of NOVOMATIC and brings the well-known Novoline machines from the arcades online. With over 1,090 games, there is the largest Novoline selection in the United Kingdom , from Book of Ra to Sizzling Hot to modern variants with Lock&Win features.

Lord Lucky - Our frontrunner for Paysafecard

There are two things that particularly convince me about Lord Lucky: the payout rates and Paysafecard as a payment method. Triple Triple Chance, for example, runs at 95.43%, and overall the payout rates reach up to 95.63%. At other German casinos you sometimes look in vain for such high RTPs. Deposits via the Paysafe Wallet are possible from £ 6If you have deposited using this method, you can easily use it for withdrawals from £ 6Your request will be processed within 24 hours and your money will then land directly in your account.

Wildz – Good for Promotions & Loyalty Program

What actually makes a good loyalty program? Wildz provides the answer.

There are also new tournaments and promotions almost every week. Perfect for anyone who wants to be offered more than just a standard bonus in the long term.

Lapalingo - With the highest payout rate

Lapalingo calls itself the best casino in the United Kingdom. A bold statement, but is it true? Looking at the payout rates, the answer is: Absolutely! With slot machines like Book of Dead, Starburst or Gonzo's Quest, the RTP values ​​are often up to 10% higher than the competition.

Over 10 years of experience in the gambling market in United Kingdom

Current, understandable information for better decisions is what I have been working on for over ten years on the market in United Kingdom for reputable online casinos and gaming halls.

We have tested numerous casino sites and thousands of games and also provide guides and news .

Given the strict regulation, our reviews focus on the criteria that are really relevant for gaming fun.

• How we rate online casinos

The online casino games

For our test of the best online casinos we evaluate the following aspects:

• Number of slot machines and developers
• Early access to new online slots
• Availability of fixed jackpot games
• Exclusive games and developers

The differences are bigger than they seem. Tipwin has just over 100 slots, while Tipico has more than 900.

However, the number alone is not decisive. What is important is whether popular or exclusive developers and slot games are represented. For example, StarGames has the StarGames Blitz slot from Greentube in its range.

In the United Kingdom , the slot games from Novoline and Merkur are by far the most popular. My top tip for Merkur Slots is current Merkur Slots, I recommend Novoline Novoline.

United Kingdom's most popular gaming hall brands on the Internet:

• Merkur real money online casinos
• Novoline real money online casinos

Can the slots be tested online for free?

Unfortunately, it is not possible to play for play money at the majority of online casinos.

We can currently recommend StarGames, Löwen Play, Wildz, BingBong, JackpotPiraten and AdmiralBet for free online slot machine testing.

What makes a good casino bonus

Good bonuses and regular promotions can significantly increase your starting balance, but they always come with conditions.

Therefore: The highest bonus is not automatically the best choice. Fair conditions are crucial.

Important: Bonus credit cannot be paid out immediately. It remains separate from the real money gaming balance until the conditions are met.

My verdict after 10 years of bonus testing: The highest number is a trap. These six points decide:

• Payment methods: Which payment option can be used to activate the bonus?
• Minimum deposit: At what amount is the bonus activated? The usual range is £ 0to £ 6
• Match bonus amount: How high is the bonus in relation to the deposit? The usual range is 100% to 400%.
• Wagering requirements: How often does the bonus have to be wagered? The range is between 20x and 60x. Pay attention to whether only the bonus balance or deposit + bonus have to be wagered.
• Bonus deadline: How much time is left to activate and implement? Usually between 7 days and 4 weeks.
• Valid slot machines: Which slots count towards sales? Free spins often only apply to individual titles.
• Winning conditions from free spins: Winnings from free spins are also subject to wagering requirements.

Is a bonus code necessary? As a rule not. If so, casinos release various offers to choose from. Truly exclusive codes are rare. If there are any, I'll provide them to you.

My current top bonus tip is Wunderino. You can find more information and recommendations on the page about the best online casino bonus offers.

A good online casino needs high payout rates

The payout ratio, also called RTP (Return to Player), shows what percentage of the bets go back to the players in the long term. The higher the value, the fairer the game.

Important: A high payout rate is not a guarantee of winning!

There is no uniform value: depending on the slot and the variant chosen by the provider, the RTP fluctuates noticeably, in my examples below from around 84% to over 94%. This theoretical value is determined over millions of game rounds. In the short term, the actual payout rate can vary significantly.

Differences between casino sites:

At first glance, almost all online casinos in the United Kingdom have the same slots. However, the chances of winning may vary.

We also have a fixed basket of 30 slots: the five with the highest and the five with the lowest payout ratio, as well as the 20 most wanted slots in the United Kingdom . We check the same basket in every casino and note the odds set. Because a manufacturer offers each slot with several fixed odds, and each casino chooses one itself. Three examples from our benchmark, each for the Book of Dead slot from Play’n GO:

• JackpotPirates: 94.25%
• Wunderino: 87.25%
• DrückGlück: 84.18%, the house uses the weakest available odds here

That's over ten percentage points for one and the same game, just because the casino has a different RTP variant.

The casino software in a practical test

The software is the “engine” of an online casino. Whether it's a finished modular solution or your own development doesn't matter much to you. What is more important is whether the store is running smoothly.

Your practical test:

• Click through: Can you find the games straight away? Is the deposit page clear and understandable?
• Test mobile: Does the site load quickly on your mobile phone? Do the menus work without fiddling?

If you have to search for longer than 5 seconds, that's a bad sign.

By the way: The games themselves (slots from Merkur, Play'n GO etc.) run on the developers' servers, not at the casino. Which RTP variant of a slot you get depends on the provider: the manufacturers supply each slot with several fixed odds, and each casino chooses one itself. That's why the values ​​differ per casino, as you can see in my screenshots above.

Technology doesn’t matter, operation counts.

Security & player protection: recognize reputable online casinos

For me, security and player protection are the most important criteria in every online casino test. You can read about what happens if you don't play at licensed online casinos or slot sites on social media. At the beginning, I personally experienced what happens when you come across a dubious provider.

My acid test begins below. For me, three points separate reputable providers from dubious ones:

I only recommend legal casinos and slot sites that are licensed by the states' Joint Gambling Authority!

If you would like to check online casinos and providers of virtual slot games yourself, I will show you how to do it here.

This is how I check the security of casino sites and online casinos:

I click on the GGL logo at the bottom of the website. That should be the case GGL whitelist lead. I search there for the name of the online casino and compare the internet address given there with the gambling site I have chosen.

I also recognize a safe online casino by the following points:

• Technical security: the lock symbol in the browser address bar confirms a secure connection. The standard is 256-bit SSL encryption that protects your personal information and payments.
• Tools for Responsible Gambling: A good casino puts you in control. You must be able to set limits for deposits, losses or playing time in your player account. A self-exclusion function (temporary or permanent account blocking) is a legal requirement.
• External audits and offers of assistance: online casinos in the United Kingdom and online gaming libraries must have their games individually licensed by the GGL in order to guarantee the fairness of the games. Cooperation with organizations such as the Federal Institute for Public Health (BIÖG) or Gamblers Anonymous is also a clear sign of a reputable gambling site.

You can find these logos, for example, on some of my best online casinos in the United Kingdom and online gaming libraries:

Best online casinos for Android and iOS devices

In online casinos in the United Kingdom you can play on mobile just as easily as on the desktop. Casino software and games automatically adapt to the respective device. The good thing about it: You don't need to download an extra casino app. The mobile web browser is completely sufficient. However, some online casinos have a native app for Android smartphones and tablets or Apple mobile devices such as iPhone and iPad. On my special page too mobile casinos you will find what I think is the best casino app. For quick play in the browser, I recommend the following mobile casino:

Best mobile casino for all smartphones and tablets StarGames 600+ mobile slots Play Now

This trustworthy provider best meets my testing criteria for mobile gaming. There I pay particular attention to compatibility with smartphones and tablets and how many mobile phone games are available. Another aspect is how easy the casino site is to use via mobile phone. The developers put a lot of effort into this point in particular and you can easily visit the best online casinos away from home and play in your mobile browser on the go, whether on the train or in the park.

Classics like Book of Ra or Eye of Horus run on mobile without any compromises. Manufacturers have reissued their blockbusters for touch operation. The test criteria for mobile casino apps at a glance:

Good mobile experience

• Easy to use
• Many mobile games
• Low data consumption

• Fiddly controls
• Only a small selection of games
• Slow loading times for games

Availability of payment methods

In online casinos in the United Kingdom and online gaming libraries you will find services such as PayPal, Klarna (Sofort), Paysafecard, credit cards or e-wallets such as Skrill, Neteller. Mobile payments via Apple Pay, Google Pay are becoming more important.

Speed ​​counts when it comes to payouts. How quickly a casino pays out your winnings is crucial. I check the processing times carefully.

Limits and Fees: The minimum amounts for deposits and withdrawals must be fair. I also ensure that there are no hidden fees, especially when making withdrawals.

The most important payment methods at a glance:

And because I keep reading complaints on social media, here are a few tips:

Fast and problem-free payment processing is only possible if you follow the general terms and conditions!

• Enter your personal data completely and correctly in the casino account
• Complete the verification completely and do not use the data of relatives or friends
• If you want to go quickly: Always use the same payment method for the withdrawal as for the first deposit
• And once again for everyone: active bonus balances and bonus winnings cannot be paid out!

I recommend for PayPal deposits JackpotPirates, for Paysafecard it is Lord Lucky. Fastest payout offers StarGames. All details on my page about best online casino with fast payouts.

How good is the customer service?

If you have any questions or problems, available customer service is important. The currently best way is live chat, which many online casinos now have. Here you have the advantage that contact takes place quickly and you can often send pictures or screenshots. But a good online casino has more than one type of contact. Here you will find the most important facts about the individual contact options for customer service:

Customer service at online casinos and online gaming arcades in the United Kingdom also shows whether a provider is really reputable.

In addition to the contact types, I test the response time and ask the same question across multiple channels.

In addition to the friendliness and the service times offered, ideally 24/7, I am particularly interested in the quality of the answers. Because at the end it is for good online casinos It is crucial that you receive a satisfactory answer to your question.

Good customer service is

• Available around the clock
• Accessible in German via many channels

• Long waiting times
• No German-speaking customer service

Conclusion – many reputable online casino sites

The bottom line after over 10 years of online casino testing: The market in United Kingdom is limited but safe, and the top group is there.

The market looks very good for players in United Kingdom. There is plenty of potential for the best online casinos among legal and reliable providers that provide you with lots of games, a mobile app, the most popular payment methods and German-speaking customer service. The differences between the individual providers are sometimes quite large, but with the help of the tips from my online casino experiences and the detailed comparison with my test criteria, you already have a good overview of the market and can therefore specifically choose the best online casino for you.

At the beginning of my page I have listed the currently Best online casinos in the United Kingdom. At the top is currently StarGames, followed by further test winners in individual categories.

Mark Seibert – author and casino expert

Compared to other markets, the selection is manageable but sufficient: in Great Britain, for example, there are around 870 active online casino licenses, in the United Kingdom the market is significantly narrower. The really annoying thing is the limited game selection and the strict limits. They shape which providers I recommend and how my test turns out. Depending on your preferences, you can choose your best provider, simply using the categories from my website Online casino test.
