Choosing the best casino sites

Aside from having the possibility of being a fast source of big money, online casino sites are now booming more than ever before. In fact, a new casino is launched in the UK almost every month. So, you can expect that all the operators of these online casinos will do their best just to get your attention. More than luring customers with the usual glitz and glam, online casinos will also entertain you to the max. Can you believe it? Even entertainment can be transferred and shared online now.

So, there’s no way you will ever leave an online casino without having loads of new gaming experience. At the end of the day, you’ll be surprised at how much you can get in the digital world. But since there are hundreds of online casinos to choose from, it is up to you to choose one according to your taste and preference. But don’t worry because we already prepared the things that can help you choose the best casinos. We selected the casinos on this page based on hands-on experience and the following things to consider:

License and regulation

When it comes to finding a reliable online casino, it is wise to ensure if it is well-established and licensed by the UK Gambling Commission. The only way you can make sure if the casino offers legal card games, table games, slot games, live games, and sportsbook in the UK is by checking its license. Avoid dealing with illegal operators as you can never guarantee your safety in their hands. Dealing with illegal online casinos will not give you the support and fight you want if you end up being scammed.

So, remember to check the footer as it always shows the casinos’ licenses. You can also check the About Page of the casino which normally reveals the complete detail about their registration and license number from one or more Gambling Commissions. All regulated and licensed casinos by the UK Gambling Commission ensure players that it is safe and secured.

Casino software

Now that we’re down on the casino software, let’s see if a casino has a future to lead the industry. It is important that you know the software the casino uses. The casino software does not only reveal the kind of game compilation you can expect but also the gaming experience. Each online casino has a list of software providers up their sleeves especially if they can’t make their own games. In fact, one of the main reasons why customers register an account with a casino is because of their software providers.

These game developers serve as a great lure to customers since they supply that games that players like you want. Aside from the jackpot price, it is the casino software that players came for after all. So if you want a decent online casino to deposit your money, make sure they are supported by the leading software providers.

Most importantly, check if you still have to download the casino or just access it in your browser. The best casinos in the UK allow players to enjoy a hassle-free casino experience by making the casino accessible in browsers. No need to free up your space or manage your device’s memory disk, if you can just fire up your search engine and enter the online casino’s website.

Device compatibility

Aside from being licensed and regulated by the UK Gambling Commission, another important thing is the casino’s device compatibility. The biggest advantage of playing in an online casino is its accessibility in different devices regardless of your location. Thus, it is worth to check if the online casino you want to deal with is available on all platforms.

Can you access it in your desktop, laptop, tablet, or smartphone? The more platform devices you can access it the better. This way, you can play any casino game or bet on sports books even while you are out or taking a long bus ride.

Game compilation

Since the online casino sites are booming in the market, more software providers pop out in different parts of the world. As a matter of fact, the leading software providers in the UK like NetEnt and Microgaming also supply games across the world. Over the years, online casinos especially continue to build their game compilation to satisfy players until they reach thousands on their lists.

But more than just pure numbers, we also made sure that are recommended casinos also offer the best games ever. Sometimes it is not just that number of games you should judge but the quality of the games they offer. When it comes to quality, we can say that our UK casinos offer high-quality games that players from all over the world enjoy.

From table games, card games, live games, slots, instant plays, to sports betting, you will never get bored as long as you stick with our best casinos in the UK. Most of our top-rated UK casinos offer a wide range of casino games that promises entertainment and huge jackpots.

Casino site bonuses

Casino Bonuses, isn’t that one of the best things in playing? Ever since casino bonuses became a huge customer magnet, those quickly became a permanent part of online casinos. Even though each online casino offers different types and sizes of bonuses, bonuses are there to stay. Besides, who does not want to grab some casino bonus no matter the size is, right? Even casino high rollers would love to get some not to mention if it involves some free spins on the hottest slots.

The most common bonuses that you should look into an online casino include the welcome bonus, no deposit bonus or extra spins, and reload bonus. Welcome bonuses are usually matching bonuses, such as 100% or 200% up to a certain amount. If you are a lucky player, you can even spot a casino that offers a cashback bonus. With the cashback bonus, you can definitely reduce your loss and increase your chances of winning after you claim your cashback. One way to spot an online casino that offers tons of bonuses is by looking up its operator. Once you know that operators that are very generous expect that all casinos they operate offer similar bonuses.

Some bonuses are specially offered only for new players while others are for loyal players. Some T&Cs or terms and conditions may also apply in the bonuses which include the wagering requirements and bonus conversions.

Most bonuses also have an expiration date so all bonuses that you fail to claim within its limit will be forfeited. Those bonuses will not wait for you forever so be sure to play them once you have the opportunity.

Casino site payment methods

Since we already mentioned the bonuses and wagering requirements, you have to let go of some money obviously. Without the physical chips and cash to use in the casino, you have to rely on whatever payment method the online casino offers. So basically, it’s worth spending some of your time in checking the payment methods that the casino offers. Sometimes online casinos display their offered payment methods at the footer.

You can also find the complete list of payment methods they offer in the Terms and Conditions. Some casinos may offer a wide range of casino games and bonuses but not the payment option you prefer. It is important to look into this matter since the casino’s offered payment method can also be a deal maker. The most common payment methods that online casinos offer include Debit and Credit cards, e-wallets, mobile payments, and bank transfers.

You can even spot an online casino that offers a cheque which is rare especially in UK casinos. So ask yourself, which of the casino’s offered payment method do you prefer? Which one is already available to you? Moreover, while most payment methods you can use are free, there are also some that require fees. Each payment method also varies in speed and online security so watch out.

Speedy cashouts

Most of the time, players tend to get a little excited when they see the flashing bonuses. But, they get disappointed once they send a request for cashout and are expected to wait for a few days. Have you encountered this same problem before? If yes, then you are not alone because a lot of customers get through this kind of problem. They are too excited to check the casino’s terms and conditions when it comes to getting their cash out. There are pending and processing period to get through before you can get a cashout.

Depending on the payment method you use, you can get speedy or delayed cashout. Generally, the payment method that requires a fee is the one that offers fast cashout. So if you are really in a hurry to get your hands on your winnings, you might want to spend extra on fees. But if you are willing to wait, you can opt for other options. Even if it means it would take a week to be transferred on your account, it is up to you.

So, be sure to find a casino that is honest enough to reveal the total pending and processing days to transfer your winnings. This will save you from a lot of frustration and time for waiting.

Customer service

Coming up in the last slot is the casino’s customer service. Every customer wants good treatment especially when it comes to dealing with problems and inquiries. All licensed and regulated online casinos are monitored by the government from the games they provide up to their deposit and withdrawal transactions. Whatever payment option you use, it is covered by certain laws of the country in which they are registered.

So if you have a question, you should be able to reach the casino’s customer support via Live Chat, email, or telephone. It’s better if the casino offers a 24/7 customer support so you can contact them anytime you need help. Regardless of the device you use, the casino should respond to you within 24 hours after sending them your concern. Don’t make a mistake of disregarding the casino’s support system since you can never know when you will need assistance.

You might not realize it yet but, not all casinos are as responsive when helping customers as they do when getting deposits. Thus, reading the reviews is very important since you gain additional detail information that casinos will not reveal. A casino with a good reputation for handling customers is always the best place to visit. Here at Gambling Bulldog, we see to it that every online casino review we make covers the customer support. The faster response you can get from a casino the better.

Apparently, choosing the best casinos in the UK do not always depend on the casino’s design and flashing jackpots. You can’t just pick any casino you see and register an account then regret later. You have to do some homework to guarantee your safety as well as the gaming experience you want.

How are online casino sites regulated within the UK territories?

When it comes to the regulation of online casino sites in the UK, everything is pretty clear and direct. Since the first license was granted in 1994 by Antigua and Barbuda, the gambling laws in the UK remained updated. Due to the awareness that Tessa Jowell raised in 2003 the importance of the gambling laws in the UK led to the creation of the UK Gambling Commission.

On behalf of the UK’s Department of Media Culture and Sports, the UK Gambling Commission was established to regulate online gambling. Under the Act of 2005, the UK Gambling Commission aims to:

  • Guarantee that there are no links between gambling and crime
  • Guarantee that online gambling is done fair and square
  • Provide protection to players especially those who are under 18 years of age and are susceptible to abuse and harm

Due to the booming online gambling, the UK Gambling Commission was established for the British government to regulate the industry. The UK Gambling Commission is the one that conducts that licensing procedure for all online casinos in the UK. In return, the owner and operators of all online casinos in the UK pay licensing and tax fees to the commission. Before a business starts to operate, a license must be obtained first from the commission.

But just as there are different types of business permits to secure in the UK, gambling license varies too. Depending on the form of gambling the business wants, any or all of the following licenses may be required:

  • Operating license
  • Personal function license
  • Personal management license

These are the types of licenses that the Gambling Commission issues to any business to start an online casino site. License holders are charged with an annual fee to keep the validity of their license. This applies whether the casino wants to offer sportsbooks, BINGO, slots, live games, table games, or card game. In addition, the commission also charges tax fee to online casinos since casino players in the UK don’t pay taxes from their winning cashouts.

Thus, it is the job of the commission to pay 15% Point of Consumption Tax of their total gross profit. This is of course stated under the 2014 Amendment to the Gambling Act of 2005. Even if the online casino operates outside the UK, they are taxed as long as they have players in the UK. If the casino fails to pay the required fees, the UK Gambling Commission will automatically revoke the license. The worse for them is that the casino will not be able to obtain the license anymore.

But one of the best things that players can thank the commission for is the Data Protection and Cyber Security Standards. The commission also implemented these additional regulations to guarantee the welfare of the players’ interest. If the casino didn’t pass all the introduced regulations by the commission, they will not be issued a license to operate in the UK. Operating in the UK without a license is illegal and subject to punishments for breaking the law.

What is a white-listed online casino?

Now that you already know the license and regulation in the online gambling industry, have you heard of white-listed casino sites before? Does the term “white-listed” even ring a bell in you? If you are a businessman, we’re sure that you already know the meaning of this term especially its importance. Just like other types of business, being white-listed is important in the online gambling industry.

Besides, who in their right mind would want to transact with a non-reputable casino? When it comes to business, earning a good reputation is always a must if you want to attract customers. Here in Gambling bulldog, we make sure that our recommended and best casinos in the UK are 100% white-listed. This means that our casino sites are safe and reliable from the games, up to deposits and withdrawals.

Though some payment methods really take more time to transfer funds, your winnings will surely arrive within the given time frame. In addition, white-listed online casino sites have an excellent customer service so expect it to have a telephone and email support. Most online casinos today even have a Live Chat support where you can get an instant response.

Thus, it is more preferred by most players nowadays since you no longer have to make phone calls or create an email. It is more straightforward and definitely faster.

Obtaining the UK casino site license

Then, after going through a strict screening process, the State Secretary for Culture, Media, and Sports have the say whether the casino’s presentation meet the standards or not. Once the casino successfully passed this process, their products and services will be allowed by the UKGC to enter the UK territories. But if they failed to comply with the requirements; the UKGC will reject their application.

Take note, any online casino from outside the UK that does not contain the UKGC and any of the gambling jurisdictions’ logo is illegal under the Gambling Act of 2005, Section 331. Therefore, it is not also considered as whitelisted and should not be entered by casino players in the UK.

Top 4 casino games that you can find in the best UK casino sites

Well, don’t fret because no one is pressuring you. The best online casinos in the UK are here to stay so you have a lot of time to try at least half if not all of their games. But, do you know the top 5 casino games that UK players love?

Aside from slots, let’s not forget roulette which is one of the oldest casino games in the world. If there is a game where you can rely on pure luck, it is most probably roulette. Not unless you have a laser fast eyes that can follow the ball and estimate where it would land, then you could call that a skill. But since most casino players are clearly not “supers”, roulette players just bet and hope to get lucky. So, savour the excitement the slowly bubbles from the moment the roulette starts to spin and the ball stops to a number.
