Our Casino Reviews Start with the Welcome Bonus

In order to provide the best casino reviews, we have to go in great detail. The first step is evaluating the welcome bonus, also known as the new customer offer. We go through every important aspect of the casino bonus offer, to come up with a verdict.

It’s an important part of the rating each casino review showcases. You too should put great thought into the welcome bonus and have it high on your criteria list. Luckily, when carrying out UK casino reviews, in particular, the bonus terms are easy to find, but we still need to analyse and interpret them.

Moreover, due to the nature of casino bonuses, we split them into two different sections. They are both equally important and deserve the same attention. This is why you will find two bonus sections in our casino reviews. As we pointed out, one is for the new customer offer, and the other for ongoing casino promotions.

You will notice that we go in greater detail when it comes to the welcome bonus terms. The reasons behind this are unusually high wagering requirements and low cash out limits. It’s something that some players overlook.

Bonus Terms Play a Vital Role

Some bonuses look attractive, but in reality, not a single player can win and withdraw winnings. This is where the respective casino review published on Casinocountdown can help you out before you commit to a poor casino bonus offer.

Some of the bonus terms we compare and benchmark in our casino reviews are:

  • Wagering requirements
  • Minimum deposit
  • Maximum cash out limits
  • Game contributions to wagering requirements

Online casinos prefer to hide behind a veil of strong jargon words that make it hard for new players to understand the nature of the bonus offer. It is something we cannot hold against them, because UK casinos have to be transparent with all terms. This, in turn, makes our UK casino reviews and the bonus sections merely an interpretation of what they mean and how they compare to others.

Reviewing New Online Casinos – Volatile Necessity

There are new casinos getting launched on a weekly basis. They are an important part of the online gaming eco-system, just by being a fresh option for casino players. Nevertheless, they are considered volatile because players rarely know or even check the company behind the brand. Unsurprisingly, casino reviews based on detailed and unbiased research can remove this mystery and bring forward all the details that concern you and your safety.

Granted, there are new UK online casinos regularly, but we prefer to hand-pick only the reliable ones. Once in a while, we review a new online casino that doesn’t uphold to our high standards.

In short, the best thing about new online casinos is the welcome bonus. Besides that, in our new online casino reviews, we talk about the product and the service quality they provide. If we know who the owner is, we like to expose that as well.

The Casino Game Offer Compared

The online casino games are the foundation of the casino’s product, which is why games also play a big role in casino reviews. UK or not, it’s what any player is going for. The casino game offer is much like an iceberg, where players see the games only, but they don’t see the other settings and details, such as RTP, max jackpot, and whether they can play the said game with bonus money.

While casino games and online slot reviews are in our scope, we don’t dwell on them in our casino reviews. We take a different perspective, from which we analyse the:

  • game filters
  • user interface
  • quantity of games
  • diversity of casino games
  • And whether the casino has the latest games

All of these combined together should provide a complete and pleasant gaming experience to any online casino player. Ticking all of the boxes from the list above is a priority at any of the best casinos online in the UK.

There is more to it than just what you see at first glance. We spend at least an hour going through the games and checking if everything works as intended. In addition, we like to dig in the T&Cs.

Some casinos have had the audacity to change slots RTP without giving notice to their players. Things like this are covered in the casino games section in our online casino reviews. This is a good opportunity to praise the UKGC’s effective governance of the gaming market because this goes against their policy, and the said casino was sanctioned.

Considering the majority of casino games online are online slots, we speak of them as well. We cannot keep every single casino review updated with every game release, but we do evaluate its quality at the time of writing. Checking if the online casino has added the latest video slots is an easy process which indicates whether the operator has a competitive product. If you are interested in a specific slot game, make sure to check out our online slot reviews, and see if there are any new slots online that might be of your interest.

The Live Casino Experience Tested

A few years back, our job conducting casino reviews was much more difficult, mainly because there were more live dealer providers. Online casino operators were competing who will have the most diverse live dealer offer. Nowadays, it’s all about Evolution Gaming. Nevertheless, this doesn’t mean that we’re skipping this section. In our casino reviews, we talk about the:

  • bet limits
  • number of live dealer tables
  • live casino bonuses

Although the “thumbnails” look the same, these are the parameters the operator can adjust.

However, the sites offering live dealer games in the UK come with their exclusive tables. This is something that we think is extremely important and we point it out accordingly in the casino reviews. Having exclusive live dealer tables means the operator can organise and offer live casino game tournaments and live casino bonuses.

Playing Casino Games on Mobile

The United Kingdom casino market is privileged when it comes to mobile play. UK casino players are in an advantage over players from other regions because the casino apps are available in Google Play. The same applies to iOS users, and they can get these apps from the Apple App Store. We also do mobile casino reviews, but no separately. These sections are integrated within the casino reviews.

We prioritise the mobile user-experience. The diversity of mobile casino games is important, but nowadays it’s becoming irrelevant because all games have their mobile versions. Since these are UK mobile casino reviews, we also check for native apps. The casino apps which you can download from Google Play and the Apple App store are called native apps. In general, most mobile casino players first use the web app, and if they like what they see, then they proceed to downloading the app. This is something we recommend as well.

A thing worth pointing out is that mobile casinos have advanced so much that the native app is considered obsolete. Web apps are optimised to perfection performing to the same level as native apps.

Online Casino Payment Terms Reviewed

Experienced casino players know that depositing at UK online casinos is not a problem, but withdrawals can become one. Online casino operators proudly boast the deposit limits, the terms and the options you have at your disposal. However, you won’t find the withdrawal terms featured on any page, except the FAQs, and the general terms and conditions. Some UK online casinos have dedicated pages on their withdrawal policy.

Some bits are fixed, but others, while important, can be changed at the operator’s discretion. This is where our online casino reviews come into place. In most cases, there’s an issue with low withdrawal limits, or we know of complications that arise with the KYC down the road.

In addition, we recommend a payment method as well. There are some hidden terms, mainly fees which amount to a lot in the long run. One of the differences between our UK casino reviews and ones that are non-UK is the focus on PayPal. casinos accepting PayPal are a safe pick for a number of reasons. The one we like to point out is PayPal’s Customer Protection.

We have to point out the recent growth of the new payment method Apple Pay among UK sites. Although available to Apple product users, it adds another convenient option to UK casino’s arsenal of payment methods.

Customer Support Approach

We use our casino reviews as an opportunity to take the customer support system for a test spin. The online casino customer support needs to be available, ideally 24 hours a day. As transparent as they are, issues do arise and often they need to be resolved instantly. This is exactly why we cover the working hours of a casino’s customer service department. And if we want to provide the best UK casino reviews, we need to reflect on the customer support open hours in the UK.

We also take a look at the various channels. Our casino reviews usually tick all of the boxes in this area. An online casino should be reachable across all major channels, including email, live chat and over the phone. FAQs are often overlooked but they too can be of help to your gaming experience.

In our experience, a few UK casinos don’t make their contact information accessible to all players. We provide all of the contact information including the phone number and e-mail address. If it's a review of a UK casino, the details provided apply to UK customers.

Live Chat Overview

As a general rule, live chat tends to be the go-to customer support channel. If available, we always do a live chat test as part of our casino review. We look to see how helpful the agents are as well as the response time. No one wants to wait for hours to get some form of feedback.

Of course, we take into account the type of casino. In our new casino reviews for instance, where they are still building a player base, round the clock support is not always necessary. Casinos that target a wider audience, on the other hand, must make themselves available 24 hours a day. Each casino review is specific to the actual situation of the casino site.

Security Cannot Be Compromised
security of casino reviews

The one and only pre-condition for any online casino to be showcased as a UK online casino is to bear the seal of the UK Gambling Commission. Without it, the casino’s operations are illegal in the UK and should not be considered. Over the past 20 years, the UKGC has made steps in the right direction, becoming a role model for other regulators.

In the security section of our UK casino reviews, you can always find a reference to the casino’s licence number, and whether it’s valid. This way, you’re only a click away from checking the recent track record and if there have been any sanctions or penalties against the operator.

Besides the track record and if the operator still holds the UKGC licence, we also talk about:

  • Third-party software audits
  • Responsible gambling tools and mechanisms
  • Discrepancies in the general terms and conditions (terms of use)
  • Any awards the operator might have won
  • Special tools that improve player’s safety
  • KYC policy terms

Carrying out UK casino reviews is much easier compared to reviewing their international counterparts. In some instances, the UK casino version is different from the international one to a point, it acts like a different online casino. However, to you as an online casino player from the UK, this is completely irrelevant.

Responsible Gambling

Fortunately, responsible gambling mechanisms and player support are mandatory in the UK. This makes our job reviewing online casinos much easier. Nevertheless, we still go through all the tools and policies, both in the UK casino reviews, and the ones that apply to other regions.

Having fun playing casino games can easily turn into irresponsible gambling. The UKGC made this a law, so players can have some sort of safety net. Needless to say, it’s our duty to advise moderate gaming. If you’re even in the slightest dilemma, it’s worth taking a step back and evaluating your gaming habits. All online casinos that hold a UK licence can be held accountable if they fail to conduct a KYC procedure, by accident or on purpose. We do not go in great detail in reviews of UK online casinos, only because we know that the UKGC is there to take action if necessary.

Casino Reviews Beyond the UK

Our main focus at Casinocountdown are our UK casino reviews, which is a well-regulated market by the government. In some jurisdictions like Australia, gambling is not received well by the authorities. This is why besides showcasing the top casino operators in each market, outlined in the table below, we talk about other things related to gambling: safety, bonuses, payment options, and other important aspects.

What is the most trusted online casino?
Any of our UK casino reviews must abide by the fundamental security measures before getting the green light from us. You can rest assured that all of the ones listed on the page are safe. We do, however, suggest checking back to our list of the best casino reviews for the top-rated options.
How do you know if an online casino is legit?
There are certain elements that you must look for to ensure that an online casino is legit. A UKGC casino licence is always the first place to start. Of course, there are many other aspects but we point this out in our security section on this page.
Why should I trust your casino reviews?
Our team of experts have reviewed over 300 online casinos. We promise to base our ratings on the facts. If you have your doubts, you can always refer back to the operator. We also provide more details about how we go about our casino reviews on this page.
Do online casinos actually pay out?
Licensed online casinos follow strict ruleset and laws, and they have to pay out all winnings to their respective customers. Failing to pay out player’s winnings results in investigation conducted by the UK Gambling Commission. Besides heavy fines, the Gambling Commission can revoke the operator’s licence immediately.
