Do you like extraordinary casinos? Mason Slots could be the gambling website you are looking for. It sounds like a brilliant idea to choose the greatest conspiracy theory of all time as the casino theme. And the selection of games is impressive: there are over 4000 titles.

Mason Slots Casino Review

At first glance, Mason Slots has everything a player’s heart desires. But I took a second look at the online casino and took a closer look at the provider. In my review you can read how my Mason Slots experiences with the different game categories, bonus offers and the payout percentages went.

In order to be able to give a Mason Slots rating that is as objective as possible, I first lay down a few test criteria: In addition to the factors mentioned above, in this report I also deal with the performance of the website on mobile devices as well as the betting limits. Furthermore, you get an overview of the company behind the virtual casino and the security aspects are not neglected either.

The software & website in detail

First of all, I can say that I really liked the website with its simple design and muted colors. As a result, on the first visit you had the feeling that you were dealing with a reputable provider. In addition, everything is clearly structured so that the most important categories with casino games can be recognized immediately.

Unfortunately, in terms of categorization, I also had less good Mason Slots experience. In the area of table games, there are also some live dealer games, for which there is actually a separate section. Furthermore, there is no separate category for scratch cards. You can only find these if you enter “scratch cards” in the search bar or set a filter for the software manufacturers.

Mason slots fraud or serious?

Not only a valid license is important when it comes to guaranteeing you as a player the best possible security. Our Mason Slots experience shows that you are dealing with a license from the Malta Gaming Authority, which is recognized throughout Europe. Casinos that can have a license from this authority are considered safe and reputable. Thus a Mason Slots fraud can be excluded. In the case of our arcade, the license number is MGA / B2C / 394/2017.

In addition, other factors play an important role, such as the encryption of your user data. Mason Slots refers to the IT company Cloudflare and guarantees a secure 128-bit encryption to protect your personal data from third parties. A Mason Slots deception can thus be largely ruled out and nothing stands in the way of a safe gaming experience!

In the event that a player should discover critical gambling behavior, this online casino relies on cooperation with well-known and trustworthy aid organizations such as GamCare, Gamblers Anonymous and Gambling Therapy. Due to years of experience and trained staff, players get quick help here. So the Mason Slots Casino can also score in this respect.

Who is behind Mason Slots Casino?

Mason Slots has only been on the market since summer 2020 and is therefore one of the youngest online casinos operated by N1 Interactive Limited. There isn’t too much to say about the company itself, except that it has had its headquarters in Malta since 2017 and is now a very renowned company in the iGaming industry.

On the Internet you can find consistently positive feedback for the virtual casinos, for which N1 Interactive LTD is also responsible. For example, you can find a review of Bob Casino on our Online Casino Portal. Spinia Casino and Betchan Casino are also included.

The Mason Slots mobile app

The mobile app knows how to convince in our Mason Slots review. Nothing caught our eye here that we would record as a negative point. The operation of the app is designed to be very user-friendly and intuitive. Accordingly, the navigation bar is directly connected to the deposit button and prevents annoying searches.

In the lower area of the Mason Slots app you also have quick access to the entire casino area and your favorite games. In addition, almost all games can also be played within the app. a download is not necessary. All you need for a smooth gaming experience is the latest version of the iOS or Android operating system.

Security and Regulation

At the beginning of our Mason Slots test, we went into the security and seriousness. These aspects are particularly important to us as they are crucial for an optimal gaming experience. A reputable casino should be able to show a Europe-wide valid gambling license. In the case of Mason Slots Casino, this is the Malta Gaming Authority.

The encryption of the website is essential. Here, too, the provider relies on the renowned IT company Cloudflare. This company protects your personal data with 128-bit SSL encryption. This means that no information about yourself gets to third parties and nothing stands in the way of safe and carefree gaming.

Mason Slots Security and Regulation

But independent test laboratories such as GLI or eCOGRA also provide additional security. These laboratories are responsible for determining the average payout rates. We weren’t able to find a lot of detailed information about the RTP values ​​in Mason Slots Casino, but in particular large game manufacturers such as Microgaming, NetEnt or Play’n GO have their games tested at regular intervals.

Customer service

A competent customer service in an online casino is therefore so important, so that both experienced players and casino novices are helped with problems. Mason Slots customer service implements exactly that and scores points across the board. During the test, I found out that you can reach support in two ways: via email and live chat.

I have had the Mason Slots experience that the customer service is very friendly and helpful. Any questions I had about bonuses or payout percentages were resolved. The staff are actually so nice and offer to use a translator so that you can write with them in German, Finnish and other languages. So I have nothing to complain about.


Seriously, Mason Slots deserves admiration. It holds the MGA license, takes care of player safety and offers an extremely creative loyalty program. On top of that, the site is just perfect in terms of usability and the game selection literally enormous. Even if the bonus conditions are not the best, they are still within the industry average. The only thing I didn’t like is no warning about the need to wager the deposit amount before withdrawing.

  1. Betrug! Gewinne werden nicht ausgezahlt sondern konfisziert obwohl nichts in der AGB steht sondern irgendwo auf der Homepage versteckt das ist irreführend und beabsichtigt damit sie nichts auszahlen müssen! Ich werde definitiv hier nichts einzahlen und empfehle diese Seite niemanden. Rechtliche Schritte werden folgen weil Masonslots absichtlich und wissen die Spieler auf den Trick reinfallen lässt. Wenn es nicht so wäre könnte man die einsätze bzw freispiel kaufen sperren, das machen die aber nicht. Ich wurde um 1000€ betrogen. Finger weg von Masonslots
