Our expert team set out to review STS Casino from all angles. We used our casino review methodology to find out what makes it tick and where it misses the mark. They considered the fairness of the casino's Terms and Conditions, licenses, complaints from existing players, customer support, limits, and other important factors to figure out whether this casino is safe and legit, an outright scam, or somewhere in between.
Our findings led us to the casino's Safety Index. This score shows how safe and fair the casino is. With a higher Safety Index, your chances of playing and receiving winnings without complications increase. STS Casino received a High Safety Index of 8.7, which means it ranks well for fairness and safety. It is a great pick for most players. Dig into STS Casino with the rest of our review and see if this casino is right for you.
Safety Index of STS Casino – Is it fair and safe?
We calculate a casino's Safety Index based on an elaborate formula that takes into consideration a wide range of information that we have collected and assessed in our review. These involve the casino's estimated revenues, complaints from the players, T&Cs, blacklists, and so on.
In our review of STS Casino, we meticulously evaluated and analyzed the Terms and Conditions of STS Casino. To our best understanding, there are no rules or clauses that could be viewed as unfair or exploitative. This is a favorable sign, considering that such rules could potentially be leveraged to deny the players their rightful winnings.
STS Casino is a big online casino based on our estimates or collected information. This casino has a very low value of denied payouts in player complaints with respect to its size (or it hasn't had any complaints). We consider both the casino's size and the number of player complaints and how they correlate, seeing as bigger casinos tend to receive more complaints due to the larger number of players.
Based on our findings, no important casino blacklists feature STS Casino. If a casino is included on a blacklist such as our Casino Guru blacklist, this could hint that the casino has committed some kind of misconduct towards its customers. We urge players to keep this in mind when searching for an online casino to play at.
Taking into account all factors in our review, STS Casino has scored a Safety Index of 8.7, representing a High value. For most players seeking an online casino that prioritizes fairness in the online gambling experience they offer, this casino is a recommendable choice.
STS Casino T&Cs reviewed
Whenever we review online casinos, we carefully read each casino's Terms and Conditions and evaluate their fairness. Many of them have T&Cs that contain rules and clauses that we view as unfair or plain predatory, since they can be held against players as a basis for withholding their winnings in certain circumstances.
We did not find any unfair or predatory rules in the Terms and Conditions of STS Casino during our review.
Player complaints submitted about STS Casino
Our casino review methodology relies heavily on player complaints, seeing as they give us valuable information about the issues experienced by players and the casinos' way of resolving them. When determining the casino's Safety Index, we consider all complaints received through our Complaint Resolution Center, as well as the complaints submitted through other websites and channels.
We have found no relevant complaints about this casino.
User feedback and reviews of STS Casino
On Casino Guru, users can rate and review online casinos to voice their opinions, feedback, or experience. Based on these, we generate a total user feedback that varies between Terrible and Excellent.
However, the User satisfaction score is only calculated once a casino has 5 or more reviews. Since we have only collected a review from one player, STS Casino does not have a User satisfaction score yet. You can find the reviews in the User reviews part of this page.
Note: It's important to note that user reviews may not always provide an objective reflection of the casino's quality. Instances exist where casinos write fake reviews to boost their user feedback score, while some dissatisfied players leave multiple negative reviews to tarnish the casino's reputation. Our best efforts are put into filtering these out and calculating an objectively accurate user feedback score; nonetheless, we do not include user feedback in our Safety Index calculation.
Licenses and company information
STS Casino is owned by STS S.A., and we have estimated its yearly revenues to be greater than $20,000,000. Based on the categorization we use, this makes it a big online casino.
As far as we are aware, STS Casino has not been granted any official gambling license.
Note: STS Casino has a connection to land-based casinos or betting establishments. These brick-and-mortar businesses are readily available and add credibility to the online casino. As a result, the casino's Safety Index is higher than would have been if it was only based on the online casino website.

Big casino
Bigger casinos are generally safer for players, because their high revenues allow them to pay out even very big wins without any issues and their quality has been proven by a large number of players. We take into account estimated revenues over the last 4 years.
Player complaints signify that the casino does not treat players right or deal with certain situations correctly. We consider the number and seriousness of complaints in relation to the casino’s size, as it can be expected that sites with more players will also have more complaints.
