They do have a toll free phone number as well as a fax number you can use for this form if you have any questions. It asks for personal information, credit card number, a Legal Statement which you have to sign, and you also have to imprint your credit card onto the form. In my many attempts to research Posh Casino, all I can tell you is that there is an Account Verification Form that players have to fill out before they can join. Although it is an RTG Casino, it is surprising that the code given is the only way you can check this casino out. Moreover, there is no website other than the 'invitation' site that you can view to ascertain what this casino offers. You have to give them an invitation code to join. While it is true that Posh Casino will give you a $500 free chip to play, there is one caveat that is suspect.
During my research of fellow players, the statements made by them are quite negative.
This is a very different kind of online casino in which you can only join by invitation only.
