How do I download msn games on a Mac G4?

I'm new to Mac and totally lost. All I want to do is play some poker this site. I have tried other gaming sites and I'm having this problem with them. I just bought the mac, because my old PC with Windows keeps freezing up. Now I still can not play and I broke through the Mac! I tried troubleshooting it says something about firewall, proxy server, Netscape and only more confusing. Does anyone know how to explain what I do? I am a total technology moron!

idk
