21.com Casino Review

In this review of 21.com Casino, our impartial casino review team carefully evaluated this casino and its pros and cons based on our casino review methodology. Our expert team has taken into account the fairness of the casino's Terms and Conditions, valid licenses, complaints from players, customer support, limits, and other significant markers to assess whether this casino is safe to play at and legit, an overt scam, or something in between.

Our calculation of the casino's Safety Index, formed from the examined factors, portrays the safety and fairness of online casinos. The Safety Index tells you how safe a casino is. The higher the score, the better your chances of a safe experience. 21.com Casino scored a Safety Index of 6.9. Please keep in mind it is one of new online casinos, and it may be too early to fully evaluate its qualities and attributes. For now, we have marked it as a Fresh online casino. Dig into 21.com Casino with the rest of our review and see if this casino is right for you.

Safety Index of 21.com Casino – Is it fair and safe?

To calculate a casino's Safety Index, we use a complex formula that takes into account a plethora of information we have collected and evaluated in our review. That entails the casino's Terms and Conditions, complaints from players, estimated revenues, blacklists, and many others.

In our 21.com Casino review, we extensively examined and analyzed the Terms and Conditions of 21.com Casino. We came across some rules or clauses that we did not appreciate, and all in all, we find the T&Cs to be somewhat unfair. Unfair or predatory rules have the potential to be held against players to defend withholding their winnings. Therefore, based on our findings, we advise caution if you choose to play at this casino.

Considering our estimates and the factual data we have collected, 21.com Casino appears to be one of smaller online casinos. 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 the casino's size and player complaints in relation to each other, as bigger casinos tend to receive more complaints due to their higher number of players.

Based on our findings, no important casino blacklists feature 21.com Casino. The inclusion of a casino in blacklists, such as our Casino Guru blacklist, could suggest misconduct against customers. It's advisable for players to factor this in when making their casino choices.

21.com Casino T&Cs reviewed

We go through the Terms and Conditions of each casino we review in great detail and examine their fairness level. 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 found some questionable rules or clauses during our review, because of which we consider the Terms and Conditions of 21.com Casino to be somewhat unfair.

Note: Our particular discoveries from the T&Cs analysis are available here.

Player complaints about 21.com 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 21.com Casino

Casino Guru, provides a platform for users to rate online casinos and express their opinions, feedback, and user experience. Relying on the collected data, we compute an overall user satisfaction score that varies from Terrible to Excellent.

Unfortunately, we do not have any user reviews of 21.com Casino in our database yet. If you have had a positive or negative experience with this casino, you can be the first one to review and rate it on our website.

Note: User reviews may not accurately reflect the casino's quality since some casinos may try to generate fake reviews to boost their user feedback rating, and dissatisfied players may also submit negative reviews to harm the casino's reputation. Although we make every effort to filter them out and calculate an impartial user feedback score, we do not include user reviews in our Safety Index calculation just to be sure.

Safety and fairness

Take a look at the explanation of factors that we consider when calculating the Safety Index rating of 21.com Casino. The Safety Index is the main metric we use to describe the trustworthiness, fairness, and quality of all online casinos in our database.

Key metrics
Terms and conditions
Somewhat unfair
Issues found: 3
Last updatedLast updated
Show detailed analysis

We go over the terms and conditions of each casino and look for unfair rules that could potentially be used against players. Any clauses we consider to be unfair result in a lower Safety Index for the casino.

Casino size
Small 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.

    If a casino appears on relevant blacklists, it is usually a sign that it has some negative qualities. We consider each blacklist and decrease the casino’s Safety Index based on our view of the situation and its seriousness.
