Grand Duke Casino is a new Playtech online casino, launched in April of 2011.
I do not recommend playing at this casino anymore. Grand Duke Casino and their affiliate program have received several complaints since their launch, so I have removed all links from this website for the time being. Some of the issues have been resolved, while others have been ongoing for a while.
I would not feel comfortable playing there myself at this time based on what I have read. They appear to be having a rough start, so I would wait and see how their reputation changes over the next several months before playing there again.
