Can anyone tell me what websites I can go to play cards or bingo, etc. for real money?

I have already tried partybingo.com and partypoker.com but those two sites say that you cant play for real money if you are living in the United States. I used to know someone from a previous job I had, that made about 500 bucks a week doing his favorite thing,,,,playing poker online for real money. Problem is I cant find a site that does that.
