I was browsing the askgamblers newest casinos section until I found a new online casino called mason slots owned by n1 interactive ltd. After verifying my account which was quite difficult to be honest, I went to the promos tab and checked what was in store. For my first deposit I received a generous 100 % match deposit bonus and 50 free spins in book of dead by play n go. The free spins are divided into 25 spins per 2 days. When it comes to bonus terms, they are visible on the main site.

Now, the max bet while wagering the bonus is 2 euros per spin. Also the wagering requirements are 40x the bonus. Moreover, mason slots has installed the automated message which does not allow you to play the excluded slots. After my bonus was added, I started my gaming session.

First pick was wild frames. I set the bet at 0.40 cents and started playing. Game was pretty bad so I had to quit after my balance was starting to decrease dramatically. I switched to golden genie and the waking wilds by nolimit. Game was pretty new back then so I had high hopes for it. That is why I increased the bet this time. Well it was pretty much a mistake since I had already lost more than half of my balance.

After this big loss I decided to play with lower bets. I found a game called cygnus by elk. So I decided to give it a try. To be honest it was pretty nice. I triggered the bonus feature and was given a nice 70x win. After that I switched to cash noire by netent. It was a new game back then so I wanted to see how it plays. I ended up losing almost everything. I was left with 15 euros. I decided to play beat the beast the mighty sphinx by thunderkick. Inset the bet at 0.50 per spin but I did not have any luck, so I lost it all. I used the whole 50 free spins in 2 days. But nothing good came up.


The bonus was pretty good and generous. To be honest I did not have fun playing here because the excluded slots list is extremely big. So to sum it up, I could not play my favorite slots. Also, the 50 free spins could be added as whole the same day instead of setting them as 25 free spins for two days. It is just a personal preference and I really stand by it.

Mason slots casino is a casino I joined earlier in May. There were two reasons I was very interested in them- the fact that they are a part of Direx NV group which is a group I've only had good experiences with as well as their welcome bonus offer. When I first noticed them I decided to sign up and claim the bonus right away.

The minimum deposit to receive the welcome bonus is 20eur but I wanted to have a bigger balance to play with, so instead I went in with a 40eur deposit. I was also glad to see that Skrill deposits were eligible for the welcome bonus which isn't too common nowadays. The offer itself was very appealing as you get a 100% match bonus as well as 50 free spins on Rise of Merlin slot. However, as it usually goes, the free spins are divided in sets of 10 per day starting the day of deposit and for the next 4 days.

After I had made my deposit, I noticed that the bonus wasn't credited. I waited for a couple of minutes but when nothing changed, I decided to contact customer support. The support was nice and professional and added the bonus manually. I had a 80eur balance to play with and wagering was 40x bonus amount, which meant I had 1600eur wagering to meet to withdraw funds. I checked their terms and saw that Twin Spin wasn't a restricted slot so being my favorite game, I dedicated my session to it. I had a few small wins here and there but nothing that would give a win over 100x bet, so within 2 hours my balance was lost. The first day I forgot about the free spins so I came back the next day and noticed I had none. I had to speak with support as they had to credit them manually since they had credited the welcome bonus manually. I did that for the next few days but didn't win anything out of these spins. 

Overall I had a pleasant time at Mason Slots casino, I really liked their game selection, bonus terms were friendly and support was really helpful. I would recommend this bonus as it has good wagering requirements, many games to play and gives a good balance boost.
