About Mason Slots Casino

Freshly launched, Mason Slots opened it’s digital doors earlier this year and have already been turning heads with their fresh casino site, strong new player bonus and killer line up of around 4700 online casino games. Though it’s early days for Mason Slots when it comes to cultivating a solid reputation we can somewhat go by the owner, N1 Interactive Ltd, and their other excellent online casinos that we already highly recommend and personally enjoy here at Freespinny. N1 are behind the award winning King Billy Casino, esteemed crypto casino Betamo and Spina Casino who we also rate highly.

Mason Slots is rather curiously themed on the secret society of the Masons, pretty novel and kind of original I guess. Unlike the Masons however the door to special ‘opportunities’ is kind of easy to access and simply requires registration as a new casino member, a process we found to be straight forward and fairly quick. Once your a fully fledged Mason you can access the impressive collection of games from a long list of expert gaming studios.

Looking around, Mason Slots is simple to navigate considering the size of the games library and this is also true of the mobile casino experience. If your a mobile slots fan for example you’ll get fast access to tons of epic titles on your smartphone or tablet in smooth instant play in a standard web browser.

Firstly, if you like plenty of choice your in the right place. 4700 online casino games sure is an impressive collection to say the least. Famous software providers are onboard to curate this games library and you’ll discover real money slots and table games from the likes of Netent, Elk Studios, Thunderkick, Play’N Go, Quickspin, Big Time Gaming, Wazdan, Pragmatic Play, Yggdrasil and more.

Slot Machines make up a large chunk of the casino titles on offer and you can opt to filter your video slots by provider, by name, by the newest slots or by the most popular slots. Some great games that feature on the most popular list include Razor Shark, Piggy Gold, Black River Gold, Viking Clash and Vampires.
