What makes a UK casino a top slot site?

As thrill seekers we all have different gambling needs and therefore our perceptions of what a top slot site in the UK is can vary quite a lot. Having visited and played on a tremendous amount of online casinos, our definition here at slotsexpert.com is, however, very clear. Below we have listed and elaborated on factors that we consider is a must for a world class slot site to have. Factors that all of our suggested casinos above of course live up to. 

– There must be a wide selection of slot machines

This is quite an obvious factor. If we love playing slots and are looking for a top slot site, the casino does of course have to have plenty of different machines that we can enjoy. But what exactly is considered to be a big amount? These days we would say that anything below 1200 slots wouldn’t be enough to qualify for the title as one of the best slot sites in the UK.

It’s not all about quantity though, but also about variety. Usually a huge amount of slots means great diversity, but this isn’t always the case. Therefore we at slotsexpert.com always pay close attention to the providers that the casino is working with as well. Not only should they offer slots from all of the most popular ones, but we would also like to see them working with some of those that aren’t as renowned.

If you’re interested in finding out what providers you may come across at the best slot sites in the UK, we have made a list of these further down on the page.

– The casino has to be licensed by the UK Gambling Commission

As a British thrill seeker it’s always super important that the casinos we’re playing at have a gambling license issued by the UK Gambling Commission. Not only is it illegal for gambling sites to offer their services to British players without one (which on its own is a warning sign), but this regulator is also ensuring your safety. It has plenty of strict rules and quality standards that online casinos have to live up to.

When a slot site is licensed by the UK Gambling Commission, this means that your personal and financial data is fully secure. It won’t be misused by the casino and cyber hackers won’t be able to get their hands on it as the operator has to have efficient safeguards against such attacks.

Being licensed also means that the casino games are proven to be 100% fair and that the payback percentage of them (RTP) is always available. In addition, all player funds must be kept on a separate bank account from the casino’s operating cash, which protects you in case they would ever go bankrupt.

Last but not least, the UK Gambling Commission will always assist you should you have a dispute with the slot site that can’t be resolved.

– Deposits and withdrawals must be smooth and free

These days charging a fee for making a deposit or requesting a withdrawal won’t cut it if a casino wants to be considered as one of the best slot sites in the UK. This is actually likely to make them on of the worst as it’s quite a terrible feature to have.

To be considered a top slot site by us at slotsexpert.com, the most popular payment methods also have to be offered. It’s definitely a must for Visa, Mastercard, Neteller and Skrill deposits to be available, but we would also like to see PayPal and Paysafe as options. 

When it comes to withdrawals we’re personally not in a hurry, but to live up to the standards of the industry we find that these have to be processed in a timely manner. It certainly shouldn’t take longer than 24 hours on average.

  • You can find great value in frequently offered promotions

While some thrill seekers prefer playing raw, the vast majority of players love taking part of bonus offers as these can increase our chances of making a profitable withdrawal. One of the factors that we carefully look at when searching for the top slot sites in the UK, is therefore how often various promotions are being offered. If the casino doesn’t have at least a couple of new ones every week they won’t make our site as one of the best operators.

  • A professional support that is always there to assist

It’s easy to turn a blind eye to the importance of a quality customer support as most of the time we won’t require any help. When issues do occur or we have a question that we really need an answer to it can, however, be a true pain in the ass if the support isn’t available and/or has a lousy standard.

Here at slotsexpert.com we know this all too well as we’ve been through it way too many times. Therefore it’s crucial for us that a casino has a quality customer support if we are to consider it as one of the best slot sites online. This means being available on live chat and e-mail 24/7, as well as agents being friendly, knowledgeable and service-minded.

– Other factors that may be important to you

While all of the UK slot sites that we have listed on top of the page live up to the above factors that we have mentioned, there may be other things that are important to you as well. You may for instance appreciate switching up the excitement of slots with other gambling products such as table games, sports betting or online poker against other players.

The vast majority of the slot sites being recommended by us have a great selection of other casino games. This usually goes hand in hand with a huge amount of slots and upholding an overall high standard of quality. You definitely won’t be disappointed by the table game experience or by playing against real dealers in a live casino.

We have, however, not taken sports betting or online poker into consideration at all. Some of the top slot sites listed by us will still offer these products though. Just don’t expect all of them to have them

Things you should definitely know about when playing at UK slot sites

If you’re a new explorer of the exciting world that playing casino online has to offer, you are certainly in for a treat. There are, however, a couple of things that are very important to know of to save yourself from potential disappointment. We have taken a close look at these things below.

– Verification is always needed before you can start playing

To comply with the regulation of the UK Gambling Commission, all legit and licensed slot sites in the UK require you to go through a verification process before you can start playing. You won’t be able to try out any games or make a deposit until this has been done.

What the verification process means is that you have to provide the casino with a photocopy of a valid ID, such as a passport or a driver’s license. This will have to be uploaded to your player account and will then be reviewed by a risk analysis team at the slot site.

Unfortunately this is not an instant process. You can expect it to take about 24 hours when playing on any of the quality casinos that we recommend.

  • Always read the terms and conditions of bonus offers

Taking part of bonuses is usually a great thing to do as they can give you extra cash to play with or free spins on a slot which you can use to win extra money from. Especially the welcome bonuses that UK slot sites offer to new players signing up tend to be very valuable.

As good as the bonuses can be it is, however, important to be aware that they almost always come with certain rules. These are known as terms and conditions and are to be found in conjunction with the offers. Usually it’s a tiny text that you have to click on to get a big list of rules.

There are many different terms that can apply to a bonus and we won’t mention all of them. To give you an example it may, however, be that deposits with Neteller and Skrill aren’t eligible for the offer. As you can imagine this is quite an important thing to be aware of.

Another important and common rule among slot sites in the UK, is that a wagering requirement has to be fulfilled before a cash out can be made. This means that the extra money that the bonus has earned you needs to be staked a certain number of times. You are, in other words, forced to play for a certain amount of money to be able to make a withdrawal.

– The casino has an edge and is always bound to win in the long run

No matter if you’re spinning on slots or playing any other casino game, it’s crucial to know that these products are designed in favor of the casino. By taking part of bonuses you can increase your chances of winning, but in the long run the slot site will almost always have an edge on you.

This doesn’t mean that you can’t win big as plenty of players have won huge amounts and even become millionaires from life changing jackpots. It does, however, mean that you should always play responsibly and view casino as a form of entertainment and never as a way of making money.

If lady luck is by your side you will make a nice cash out at the end of your session, but odds are that you won’t. Therefore it’s important for us to highlight the fact that you should never play for money that you can’t afford to lose or try to chase any of your losses.

The best providers that top slot sites in the UK offer

As playing casino online has become more and more popular, the number of companies developing slots have skyrocketed. All in all there are well over two hundred different ones, which is quite an astonishing number. Some are, however, much more successful than others with slot machines that are constantly sought after by thrill seekers.

Below we have listed those developers that are usually considered the very best ones. Many of the slots created by these fantastic providers are being offered at the best slot sites that we at slotsexpert.com are recommending at the top of the page.

What other providers can I find at UK slot sites?

A part from the above companies, it’s not that common to find that the average UK casino is working with many other providers. They may have slots from some of them, but usually they stick to machines from the most popular ones. When playing on a top slot site listed by us it is, however, a whole different story.

You can expect to find games from plenty of other providers – some that you’ve probably never heard of before. It may not always be all of the ones that we have mentioned below, but you can definitely be sure to find slots from several of them.

Is it better to play on an old or a new UK slot site?

That’s actually quite a tough question with a lot of different answers to it as it depends on several factors. In general we would say that it’s better to play on old ones. Not only have these been tested and reviewed by plenty of thrill seekers, but they probably have a much bigger budget to spend.

This budget is likely to contribute to a better gambling experience such as support agents being available around the clock and the game selection being huge. It’s definitely not free offering such things and many of the new slot sites in the UK simply aren’t able to afford them. That’s why old and established casinos are often considered to be the best.

There are, however, exceptions to the rule. Even if a UK slot site is new it may be a part of a renowned conglomerate like Betsson Group or Gaming Innovation Group. These companies are giants in the online casino industry that own a heap of different sites. If they decide to launch a new slot site in the UK it’s likely to be a really good one as they have plenty of money to spend.

A new slot site doesn’t have to have a big budget to be worth a try though. A limited amount of cash may not give them the biggest game selection or the best customer service. They may, however, offer a terrific welcome bonus and an experience that’s highly innovative. To compete with the old dogs of the industry, new sites have to stand out and these two things can be very efficient ways of doing so.

Frequently asked questions about slot sites in the UK

What is the legal age for playing at slot sites online?
As a British citizen you have to be 18 years old. This is the most common age requirement when it comes to gambling. Some countries do, however, require you to be 21 so if you aren’t from the UK it’s best that you double check with your local authorities.

What payment options can I find at the best slot sites?
Among those that we recommend at the top of the page you can always find that Visa, Mastercard, Neteller, Skrill and Trustly are supported. Many of the top slot sites do, however, also offer Paysafe and PayPal as alternatives.

Do I have to make a deposit to play slots?
Not at all! The vast majority of UK slot sites allow you to try out their games for free by playing demo versions of them. You only have to click on the slots while not being logged in to a player account and you’ll be able to spin on them using demo credits. 

How can I improve my chances of winning at slot sites?
The best way of doing this is taking part of bonus offers as these can be quite valuable. By playing on low volatile slot machines with a high RTP you can, however, also increase your short term chances of winning. Other than that it’s all up for lady luck to decide how profitable you will be.

Is it safe for me to play at UK slot sites?
As long as they have a gambling license issued by the UK Gambling Commission it is perfectly safe as this regulator has ensured that the sites are following all necessary laws and have a high standard. If a casino doesn’t have this license you should, however, stay away from it.

How can I know if a slot site in the UK has a legit gambling license?
If you pick one of the top slot sites listed by us here at slotsexpert.com you can always be sure as this is very important to us. You can, however, also find out by going to the very bottom of a casino’s site as they always front with their gambling licenses in the footer of their pages.

Why do slot sites ask me to withdraw using a certain method?
As a measure to prevent money laundering and to comply with British laws, all licensed casino sites have to follow what is known as a closed loop policy. This means that any amount deposited from a certain payment method must also be withdrawn back to the very same one.
