Our Approach to Online Casino Reviews

In online gambling, operators need to check a lot of boxes to be considered a top casino site. Just having a huge welcome bonus isn’t enough if withdrawal times are slow, and the best casino games are worthless if the site is lagging on mobile phones.

That’s why we look at all aspects of the casino during our reviews because we don’t want to judge a book by its cover. Here are typical questions we answer during the review process:

Icon for Bonus Offer

Bonus Offers
How attractive is the casino’s welcome bonus? Do they offer rewards and regular promotions to existing players? Are the bonus wagering requirements player-friendly?

Icon for Withdrawal Times

Withdrawal Times
How many withdrawal options does the casino offer? Are requests processed promptly? Does the operator offer player-friendly features, e.g., lock withdrawal?

Icon for Games

Does the site partner with more than one software provider? How many games are being offered in total? Is there a healthy mix of table games and online slots?

Icon for Design

How’s the design and functionality of the registration process? Is the casino’s interface easy to use? Does the website adapt to my mobile phone and tablet?

Icon for Safety & Security

Safety & Security
Does the UK Gambling Commission regulate the casino? Are transactions encrypted with SSL? Do reputable financial institutions, e.g., PayPal, partner with the online casino?

Icon for Fairness

What is the operator’s RTP (Return to Player)? Are there any existing partnerships with regulatory bodies such as eCogra? Do they cap cash-out of winnings from bonus money?

What are the Most Trusted Online Casinos

We outlined our approach to online casino reviews and trustworthiness is one of the elements with the highest weighting for the final score. Back in the days, this process took a very long time because online casinos held licenses from authorities across the world, including tax havens such as the British Virgin Islands. What’s problematic about these licenses is that the issuers don’t vet the applicant properly but rather sell the license to them. Whether the operator is dodgy or not, as long as commission receives their money the permit is granted.

Luckily, players in Great Britain don’t have to worry about such things, and at the same time, it makes our job much easier. In the UK, all casino sites that offer real-money games online are required to hold a valid license issued by the UK Gambling Commission. No exceptions!

What is Considered a Trustworthy Casino

We have just mentioned that all online casinos UK are fully licensed hence one could think that all operators are trusted ones. Well, technically this is true, but at we have more requirements than that.

For us, a trusted casino site should not just provide a safe platform and fair games but also care about their customers. If an operator delays withdrawals by taking an exceptionally long time, just to tempt you into reversing the action, then we don’t trust this site. At the same time, if an operator bends over backward and offers very player-friendly features, such as Casumos’ lock withdrawal feature, then we would increase the trustworthiness score for that online casino.

Speak to a Customer Support Agent Before Signing Up

A perfect way to find the most trusted online casinos is by speaking to their customer support team before registration. As questions about the bonus wagering requirements, withdrawal times, and whether the casino runs regular promotions for existing players. Whenever you feel the customer support agent is beating around the bush, it’s not proof that the casino site cannot be trusted, but it’s a sign you might want to dig a little deeper. Have a look at our live chat support protocol where we’ve done precisely that.

The Best Site for Online Casino Reviews

There are A LOT of casino reviews sites out there, and we’d like to think that we are the best. Truth to be told, other websites do a great job as well, and we’re not mad if you go ahead and compare a couple of them. However, as players ourselves, we genuinely care about the customer experience and work tirelessly to create comprehensive reviews that look at a casino site from all angles.

We would never say that we are the best site for casino reviews, but if you think we are, then this makes us very proud. If you have any questions, suggestions or want to give us constructive feedback, please don’t hesitate to do so by contacting us via email.
