Mason Slots Casino Review
In this review, Mason Slots Casino has undergone a detailed examination of its strengths and weaknesses by our team of independent casino reviewers using our casino review methodology. By looking into the casino's licenses, Terms and Conditions, up-to-date player complaints, limits, customer support, and other various essential elements, our review team has identified the safety and fairness of the casino, evaluating whether it falls into the category of being safe and legit or damaging for players.
Based on these markers, we have calculated the Safety Index, a score that summarizes our analysis of the safety and fairness of online casinos. A higher Safety Index generally correlates with a higher likelihood of a positive gameplay experience and hassle-free withdrawals. Mason Slots Casino has an Above average Safety Index of 7.2, making it a viable choice for certain players. However, there are numerous casinos with even higher rankings in terms of fairness and safety. Find out if Mason Slots Casino is the right casino for you by reading the rest of our review.
Is Mason Slots Casino fair and safe? Safety Index explained
Our process for establishing a casino's Safety Index involves a detailed methodology that considers the variables we've collected and analyzed during our review. These comprise of the casino’s T&Cs, complaints from players, estimated revenues, blacklists, etc.
In our review of Mason Slots Casino, we have looked closely into the Terms and Conditions of Mason Slots Casino and reviewed them. We came across some rules or clauses that we did not appreciate, and all in all, we find the T&Cs to be unfair. Unfair or predatory rules have the potential to be held against players to defend withholding their winnings. Therefore, as we discovered some serious issues with fairness of this casino's T&Cs, we advise seeking a casino with fairer T&Cs or at least approaching this casino with caution.
Considering our estimates and the factual data we have collected, Mason Slots Casino appears to be a very large online casino. Considering its size, this casino has an average sum of disputed winnings in complaints from players. We factor in the number of complaints in proportion to the casino's size, recognizing that larger casinos tend to experience a higher volume of player complaints.
To our knowledge, Mason Slots Casino is absent from any significant casino blacklists. Casino blacklists, including our own Casino Guru blacklist, can signify that a casino has done something wrong, so we advise players to take them into account when choosing a casino to play at.
On the whole, also considering other contributing factors in our assessment, Mason Slots Casino has achieved a Safety Index of 7.2, which is classified as Above average. This makes it an acceptable option for some players, but there are better casinos for players who value a fair and safe environment in online gambling.
Note: To the best of our knowledge, Mason Slots Casino is associated with 17 other online casinos. The Safety Index of Mason Slots Casino takes into account the qualities of all the interconnected online casinos.
Reviewing the T&Cs of Mason Slots Casino
To see how fair a casino is, we read through its T&Cs as part of every review. In T&Cs of many of them, we uncover clauses and rules which we consider unfair or outright predatory, as they give the casino the possibility to justify not paying out winnings to players in certain situations.
We found some questionable rules or clauses during our review, because of which we consider the Terms and Conditions of Mason Slots Casino to be unfair.
Note: Read through and explore our specific findings from the T&Cs check here.

Safety and fairness
Safety and fairness
Take a look at the explanation of factors that we consider when calculating the Safety Index rating of Mason Slots Casino. The Safety Index is the main metric we use to describe the trustworthiness, fairness, and quality of all online casinos in our database.
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
Medium casinoVery big group
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 and also consider revenues of related casinos.
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. Besides direct complaints, we also considered 1 complaints from other sources.
Blacklists
None
0x
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.
Other factors
Neutral
There can also be other characteristics and qualities of a casino that influence its Safety Index, such as win limits, low withdrawal limits, fake games or licenses, bad or no customer support, a network of land-based shops, etc.
Our Safety Index calculation also takes into account complaints about related casinos and complaints submitted through websites other than Casino Guru.

Been playing here for about two months now. Mostly blackjack and a few slot titles. Had a nice $75 win recently which I withdrew just to test things. Money showed up the following day so that's a good sign. The interface is simple and doesn't overwhelm you. Bonuses appear every now and then but nothing crazy. Support agents seem friendly and helpful. Overall the experience has been relaxed and enjoyable.

The slots were the highlight for me. Tried a few random ones and one actually paid out pretty nicely after not doing much at first. It was one of those sessions that looked dead until it suddenly wasn't. Glad I didn't leave too early.
Slots are the main highlight
Nice payout
Rewarding experience
Good variety of games

I mostly bet small amounts and this site allows that comfortably. No pressure to bet big. The experience feels relaxed. Definitely beginner-friendly. I had one withdrawal that took a little longer than expected but support explained why and it arrived later that same day, so no real complaints there.
Relaxed and friendly experience

Mason Slots casino has exceeded my expectations! Fast payments, exciting slots, and support that's both professional and approachable. My only slight annoyance is they could do better with bonus offers tailored for regular players.
Really fast payments, I had 200 bucks in an hour

I won 800€. I was already verified and the casino rules say only above 2000 a further verification is required, but okay, not even that important.
The Casino wouldn’t even inform me that there was a problem but I had to push the whole process all the time, while I got different requests each time, from different employees. After I fully fullfilled them, I each time got new requests, not even compliant with their own stated rules on their page. They say pdf files are ok on page but then deny it in emails. They say withdrawal up to 2000€ without further/special verification is possible but invent new already fullfilled requirements each time.
In their own documents section one can see that they haven’t even checked all my documents (the ones that were relevant and fullfilled all requests). That page also shows what is still needed while 2 employees claim that they have already been fullfilled.
dI never witnessed such a behavior, I was absolutely willing to withdraw within the first hours or days, while they maltreated me. After so much problem causing I realized I would never see my money again and so I gambled it away.
Problem awareness
Offer for support after some time
Obviously quality management processes
Excuses for not paying out
Catastrophic support
No complaint management
No compliance with own rules

i really don’t understand the bad rating here. Generaly some bad casinos are rated as good and good casinos rated as bad here on Guru….
For me personally, this is one of the best casinos i am playing at. (And i really tried many)
Sure you can loose money here, but this is called gambling! :)
Winnings are always payed out in under 1 hour (last withdraw took 15 minutes). The Support is very friendly and helpful, espacially when i compare it to other casinos.
I am very happy with Mason <3

I have been playing over a year at Mason Slots Casino, and I think the rating from Casino Guru are a some conservative. I think it is a great Casino, and they are absolutly fast to pay out withdrawal. I have not had any problems, so I dont know about their support. There could be more slots from more providers, and thats why I give them 4 and not 5, but they deserve regonition for their great site.
Fast pay out
Site works smooth
There could be more slots providers

During verification, the casino requested a call to Skype. We agreed for a certain time. This is my first call and I was very worried about him. I answered all the casino questions in detail during the call. I'm sure I provided all the information I was asked. Answered all questions. After the call, my account was blocked. "You have not passed Skype verification successfully. This decision is final and non-negotiable. " The casino does not name the reason and does not provide arguments in support of its position.
I am sure I have answered all Skype verification questions as per my data. I recorded our call and I can prove it. It's a terrible casino, don't use it.
