Rating Guidelines – CasinoTopsOnline TrustScore

As a site, we're invested in making sure that our casino reviews are high quality, reliable, and provide the best possible information for players. Let's see how do we rate and write casino and game reviews on CasinoTopsOnline and the review criteria we take in consideration.

We always investigate and look into casinos before we place them on our site. We want them to meet a number of criteria for our users, and we want to provide a valuable service to our readers.

Once we receive a submission of a casino or find out about great upcoming casinos, we then review them, taking care to see if they meet the minimum standards for what we consider to be a good casino.

What Is CasinoTopsOnline TrustScore?

As a site, we're invested in making sure that our casino reviews are high quality, reliable, and provide the best possible information for players. In order to do this, we’ve developed our own unbiased system to allocate fair and honest ratings to online casinos. The casinos’ scores are determined based on a number of factors including:

Trust and Fairness

The trust and fairness rating is determined by several factors including the casino’s license, terms and conditions, privacy policy, security features and commitment to responsible gaming. We check for confirmation of third-party tests and audits for game fairness.


For the games section rating, we look at how many games are offered, if free play mode is available and whether you need to create an account to play for free, how many live casino titles are available and if there is a sports betting and esports section. We also look at the game suppliers powering the casino’s lobby as well as how often the game selection is updated with the most recently released titles.


The bonuses score’s parameters include the types of bonuses offered, wagering requirements and expiry date, minimum deposit required, transparency of bonus terms, game limits and the number of markets the bonuses are available for.

Customer Support

When testing customer support, we look at whether there is at least one 24/7 support option, which other options are available and how efficient is the support team in assisting us with our questions. If these are not answered competently, then the score of the customer service of the casino will go down.


Payment markers include banking options, with special attention to local methods, currencies accepted, payout timeframes, deposit and withdrawal limits and fees. We also take note of any complaints from past players and look out for patterns in which the casino has proved unwilling to pay players their winnings. 

Online Casinos Rated and Approved

If the online casino has been approved in all of the above criteria, we will give a final score and create a thorough review where we analyse each point to weigh up the pros and cons. Casinos are checked periodically, and the ratings are adjusted accordingly if and when we receive new information.

We believe that honesty and transparency are particularly important, which is why we describe the good and bad sides of every casino, as well as list as much information as we can give to help players. Our editorial principles highlight exactly what goes on behind the scenes when we create our reviews. 

Not recommended casinos

What Makes a Casino Not up to Our Standards?

Sometimes, a casino isn't quite what it's cracked up to be. We don't want to list any casinos on our site which might give users a negative experience, which is why we're so keen to get feedback from users about their own site experience. We mostly consider these points to be negative for a casino:

  • Poor customer support;
  • Lack of transparency;
  • Not licensed correctly;
  • Slower than normal withdrawals;
  • Unclear terms and conditions.

These are all taken into account when we review, and if we deem any points to make a casino unsafe, insecure, or just not top quality, our scores reflect such. We make every effort to keep our scores updated according to how the casinos are currently offering their services. A casino which has significant shortfalls will receive a "Not Recommended" status from us. Casinos which have engaged in malpractices and have disregarded their players' safety will receive a "Blacklisted" status.
