poker games download mac

How do I download msn games on a mac g4?

I am new to a mac and totally lost. All I want to do is play some poker on this site . I have tried other game sites and I am having this problem with all of them. I only bought the mac because my old pc with windows kept freezing up. Now i still can't play and i am broke thanks to the mac! I tried troubleshooting it says something about firewall, proxy server, netscape and it is only more confusing. Does anyone know how to explain what I need to do ? I am a total tech bozo!
