Our Online Gambling Review Process – Gambling Sites Quality Checklist

There are no hard-and-fast rules in forming an opinion because we believe everyone is different and has different goals. We can agree, however, when it comes to online gambling ratings, we should employ as strict as possible rating criteria placing user safety and legitimacy first.

To stay true to those of the readers who want to see more technical information, we measure, assess, and test things like software, the number of games, compatibility, and novelty. Here are the steps we follow when we do gambling website reviews:

1. Check the License and Security Protocols of the Site

To us, a well-informed decision is always based on the best probability of a positive outcome. To maximise the chances of that, we recommend only the sites that have the benefit of the UKGC’s approval. We make sure that the online security is on point as well. Since there is a lot of banking going on at a high-profile gaming site, we see to it that nothing short of first-rate security systems are at work. Social responsibility is another virtuous quality we take into account. Making it possible for users to self-exclude and seek professional help is a must. Find all in one place the UK’s secure gambling sites rated and reviewed by us.

2. Try the Gambling Game Selection

As fun as ‘game testing’ may sound, we are all business when we test real-money games. We, then, share all essential details with our readers starting with the RTP and software provider. While not all the titles we review are undisputable hits, they are well-known amongst players and appreciated for their features. There’s always more to a real cash game than first meets the eye. That’s why we are very methodical about analysing and putting information such as variance, rules, bet sizes, and popularity into words. Don’t delay it, learn the ins and outs of the best UK gambling games online.

3. See If the Site Has Verified Payouts

There are two ways to go about that, and we do the best of both. First and foremost, we encourage our readers to check for an eCOGRA report. It gives an insight into the payout percentages of all games a remote gambling site has to offer. We try to use eCOGRA’s detailed reports in every gambling review UK we do. Because our gambling site reviews are done by players for players, we are genuinely interested in customer feedback. Without reading into the complaints, we use all the first-hand information we can find to make an adequate description of the best-paying gambling sites.

4. Review the Gambling Deals and Promotions

Bonuses and promotions are an inevitable part of online gambling. So much so that they are the first thing you are going to see as a new player. You can use our online gambling reviews as a trusty compass to help you tell the different offers apart and select the one that is best for you. To that end, we’ve also put together a guide to the UK’s gambling bonuses, that can certainly be of assistance to you in making sense of the best deals. This is where we get down to details and explain the fine print from a player’s perspective.

5. Research the Software Providers Behind the Platform

Most players agree that they want to be served by a reputable software provider whose name is well-known. We do our part in that we did background research of the top casino software providers featured on our best online gambling sites reviews. Ideally, we aim for those with experience and proof of concept. Even if not that popular, the software developers we recommend are legal, have an office either in the UK or Malta, and have a clear vision for their business. You could say that they are in for the long run, which is ideal for the players looking to wager on a permanent basis.

6. Test the Mobile App

A mobile gambling app is another piece of the puzzle we examine carefully. Almost all participants in the industry have migrated to a mobile-friendly solution at some point in their development. The lack of a mobile app is a big setback for the users and a misstep that leads to a lower rating given by us. Our reviewers test the ability of the best gambling apps to run smoothly on various devices and whether that comes at the cost of a tradeoff. If an instant-play version that requires no installation is available – all the better.

7. Try Out the Deposit Methods and Check the Withdrawal Times

Deposit and withdrawal times are both central to customer satisfaction when it comes to gaming. That makes it important to us to gain hands-on experience with the payment methods that are accepted at an online gambling site. We do so with a view of testing the processing time of withdrawals and deposits. The norm for deposits is to be instantaneous, whereas a conventional cashout can take from 1 to 5 banking days. The PayPal gambling sites in the UK fit the description perfectly, while having tighter than the usual, security.

8. Try the Customer Support

Along with the gambling service itself, we never forget to check if everything the customer support channels are intact. In fact, our reviewers often message helpdesk agents to see their response time and ability to help. From our online gambling reviews, you can learn if a live chat and a hotline are available along with other particulars. Count on us to check for an FAQ section and its utility. All too often, there is one, but the questions and answers are not that many nor that helpful to first-timers. If this is the case, we’ll let you know.

Contents of a Gambling Review

For us, the makings of a good gambling review are defined by the interest of our readers. Starting with information about the licence, we continue with the gambling bonus and the games of chance. The last two are tied up by way of the terms and conditions of the bonus offer, so we make sure we understand that connection and explain it to our readers.

We dedicate due attention to the payment methods that players can use for inbound and outbound transfers. We review those in terms of transfer limits, processing time, and security. Last but not least, our reviewers test the effectiveness of the customer service.
