Grandmaster Casino Logo RoundVerdict

All in all, GrandMaster is an online casino that has some flaws, but is filled with many great features. Let’s start with the flaws first. There are two things that we are not fond of at this site. The first is the lack of a loyalty program. Every online casino must find a way to reward the more loyal players, but we are sure that GrandMaster Jack will feature a program like that soon.

Secondly, a processing fee is charged for each withdrawal, which is another thing that we are not fond of. If you look on the bright side, the processing fee is pretty low – £/$/€2.5 per transaction.

Now, let’s transfer to the things that we adore about this online casino. First off, there are hundreds of great games to choose from. Some of the world’s best and most reputable game providers have made sure that gamers will have a unique experience at this site.

There are tons of monthly and daily promotions for the players and they are rewarded quite often. Cashback bonuses during weekends are also available.

Finally, there are tons of accepted deposit and withdrawal methods and they will most likely suit your needs. Transactions are secure as the site uses the latest SSL-encryption software.
