What is the difference between Asian mah jong and Jewish mah jong?

I want to learn how to play, but I noticed that the lessons at the community center near me are for the Asian version -- which is not what the women that I know play. Is there much difference?|||Well Meredith, being the smart-a** that I am, the first thought that went through my mind when I read your question was (and understanding that I have no idea in the world was mah jong is of any type or from anywhere): "This is easy, The one that has been circumcised is Jewish."|||There is no Jewish version,but it is a popular game among Jews but not our invention
