With each review, we follow a stringent process of data collection complemented by an editorial policy that ensures clear, conscise and accurate insight that can guide you in making the most informed choices.
Why Trust the KingCasinoBonus Review System?
Every casino review we produce sees multiple members of our team try and test the casino in question. We open real accounts, go through the sign-up process in full, make the most of offers and test every aspect of a casino, from its bonuses to games on offer, its security protocols to the customer service options on offer.
While it’s worth noting that we do have financial partnerships with many casinos, this does not dictate our reviews. In fact, our partnerships are born out of honesty, integrity and understanding, with all the casinos we work with accepting that they face the scrutiny of our reviewers and the cons will be acknowledged alongside the pros in our reviews.
Multiple casino experts check the reviews before they are published, based on a thorough policy. They ensure we only give relevant information that is easily accessible. In every online casino review on KingCasinoBonus, the following goes into it:
- 8 strict selection factors, evaluated and described in every review
- 2 specialists that test and review the casino
- 2 experts, including our chief editor, Ionut Catalin Marin, check the casino review before publication
- 8-10 hours of testing every casino we review
- 6-8 hours in creating and checking each casino review
- Between £10 and £100 to test and review each casino deposit and withdrawal method, looking at payment security, speed, and limits
- An average of £80 in checking game betting limits
- £1 to £50 to claim the casino’s promotions and check their true value, terms, and security.
How We Test an Online Casino
Our process takes into account a variety of steps in order to form our in-depth, informative reviews.
- We research the casino’s UK Gambling Commission licensing and reputation using our internal resources and specialised tools.
- Our team creates a live casino account to test the registration process.
- We verify every account to evaluate the efficiency and duration of the KYC process.
- We navigate the casino website on laptops, tablets and smartphones to test its mobile optimisation, loading speed, and responsiveness, especially during its busiest times.
- Our experts check for any glitches and analyse the graphics, design and layout of the platform, to ensure you can navigate it easily.
- We check the number and diversity of the available games, including the reputation of the software providers on the casino website.
- Our team tests 10 games in every available category, to verify minimum and maximum bets, game features, and functionality.
- We interact with the casino’s support team through all the means available, to check how they work, how fast they respond, and how reliable they are.
- Our team claims multiple bonuses from each casino, including sign-up bonuses, free spins, and reload offers to assess their terms, playthrough requirements, and their true value.
- We analyse the withdrawal process of the casino, by cashing out different amounts and evaluating the banking options available, withdrawal processing speed, limits, and any added fees.
- We compare our test results to our standards. If a casino meets our standards we use all the information we collected to create accurate, comprehensive, and objective casino reviews.
What makes the best online casinos?
Of course, we’re always on the lookout for the very best online casinos, but what do we class that to be?
In our reviews, any casino that receives a rating of 4/5 on all eight evaluation standards we’d consider to be amongst the best on the market today. This means that you’ll receive a high-quality user experience, a wide range of payment methods, good customer support, as well as an excellent range of games and bonuses, as well as a fully safe and secure site to play at.
Our experts don’t just settle for sites that meet our standards. They require a casino to exceed our expectations by delivering unique experiences or excelling at one of our rating criteria in order to list them on our best online casinos UK page.
What makes a bad online casino?
If we are to determine that a casino isn’t up to our standards, we won’t create a casino review for it. This is to ensure that a reader doesn’t sign-up to an unsafe or insecure casino just because it is featured on our website.
Types of Reviews We Create
We create two types of reviews: individual casino reviews and collective reviews of casino categories.
In the case of individual casino reviews, we provide in-depth evaluations of one single casino and the specific payment policy, the type of security granted by the casino, the particular games available, its offers, assistance and usability on multiple devices. While these reviews also compare the casino with competitors, the focus remains on what the site offers to UK players.
Our casino category reviews provide information about the sites that meet your specific preferences in gambling. For instance, we list together casinos with low minimum deposits, sites that provide the top titles for a game category, such as the best slots sites, and other categories that cater to your specific areas of interest. These types of reviews by category aim to help you find the most suitable casinos for your specific needs.
Rating the Best Online Casinos in UK
As we’ve mentioned, we rate the best online casinos in the UK based on an eight-factor system as standard. Our experts calculate a score between three and five according to how many of our requirements the casino meets for a specific factor, like bonus selection or payments.
Casinos that score five in any of the areas we evaluate meet all of our quality standards for that specific factor. We don’t list casinos that score less than 3 on any of the 8 evaluation factors.

Bonuses
Whenever our experts test and rate the bonus section of an online casino, we redeem as many promotional offers as possible. We generally only deposit the minimum required amount, usually £10, so we can redeem multiple deals. We test the eligible games, complete the wagering requirements and request payouts of the promotional winnings to clearly formulate our opinions on which promotions our readers would find most suitable.
Look & Feel
To properly examine the interface of each UK gambling site, we explore the platform from different devices, including desktops and Android and iOS phones. Our experts appreciate and give better ratings to online casinos that offer players intuitive and modern interfaces, including navigation options like search bars and advanced filters in game collections. We also expect the registration, KYC and banking processes to be as simple as possible.
Slot Games
We look for a wide range of slot games that are suited to a variety of bet ranges. We look for casinos that have a good variety in the styles of games, as well as a good range of different slot providers.
We place wagers ranging from £0.10 to £100, and our experts try classic, video, megaways and jackpot slots. To earn a high rating from us, a site must offer at least seven premium developers present in their catalogue, and a total of 700+ titles.
Live Casino Games
To gain a good score for a site’s live casino games offering, they must offer at least 40 top games across roulette, blackjack, baccarat and poker. We also expect a range of top games providers, with a minimum of two to secure a maximum score.
Payout Speed
These days, players expect to find a wide range of banking options, all of which should be safe and secure. We test many of the payment options, including debit cards, e-wallets, prepaid cards and, when available, pay-by-phone methods. We also ensure the withdrawal limits and processing time advertised by the website are correct. For high ratings in this section, the deposit and withdrawal limits need to be £10 or lower, the operator must at least accept debit cards and e-wallets, and payout processing times of under 24 hours.
Customer Service
To secure top marks for customer service, online casinos are required to offer support across email, live chat and telephone. We test each one, placing multiple queries that range from banking to registration, to KYC processes, game-related issues and more. Another factor that is highly appreciated by our team is the 24/7 availability of either live chat or phone support.
Loyalty
Loyalty and rewards schemes are a big part of online casinos and we explore the benefits that are offered by them. We usually wager at least £200 to reach that goal, and we look out for benefits like personalised bonus offers, personal account managers, as well as better deposit and withdrawal limits alongside quicker cashout processing times.
Licensing
Finally, the most important aspect that our KingCasinoBonus experts focus on is the licensing of a casino. We don’t partner with or review any UK online casinos that don’t have a valid UK Gambling Commission license. We also ensure that the gambling sites we present to our UK readers don’t have any suspensions or fines for not respecting the regulations.
The maximum rating can only be secured by operators who partner with industry watchdogs like eCogra and iTechLabs to offer you the safest and most trustworthy experience possible.
Why We Only List UKGC-Approved Casinos
Player safety is paramount to us, which is why you’ll only find casino sites that are fully licensed and regulated by the UK Gambling Commission across KingCasinoBonus.
Being licensed by the commission means that casinos must promote responsible gambling, help struggling players, offer transparent terms, fair games, safe transactions, and a high level of player data security, among other important aspects. What’s more, the Gambling Commission also regularly checks this to ensure that such rules are respected.
Essentially, the UKGC licence is a guarantee that the casinos you find on KingCasinoBonus are legitimate and safe.
Categorising the Top UK Online Casinos
We select the top UK online casinos based on the type of player requirements that they meet best. Our chief editor and main expert, Ionut Catalin Marin, personally verifies the selection process of online casinos by type of player and category.
These are the most common categories by which we select top-performing UK casinos:
By reputation
When selecting the online casinos with the best reputation, we first make sure they are licensed by the UKGC. We follow this up by ensuring they are well encrypted and protect your data and funds.
We also seek out game fairness certifications from independent auditors, as is the case with eCOGRA casinos, and consider the amount of time in which they’ve maintained a positive reputation in the industry.
By game software providers
We choose the sites with top titles from the industry’s most reputable providers. When creating specialised lists of Netent casinos or Playtech casino selections, for example, we also look at betting limits, game features, and how many new titles from a specific provider you can access.
By payment methods
When we pick the top casinos for specific payment methods, like in our Visa casinos list and Mastercard casinos selection, we make sure their payment policies also make your Visa or Mastercard transactions easy and convenient.
With top casinos that accept Neteller and our Skrill casino listing, we also check if you can access bonuses and other benefits by depositing with these methods.
By the provided sign-up bonuses
Our experts select and constantly update our top UK casinos that offer the best sign-up casino bonuses list with sites where you can find multiple sign-up options, like no deposit required offers, free spins on registration, and welcome packages.
We consider these bonuses the best because they have low wagering requirements, and high value.
