Virginia Casino Gambling Is Gambling In The US Legal?

Is gambling in the US legal? - virginia casino gambling

I live in Virginia. I know there are reservations casinos in Nevada, New Jersey and American Indian. I assume that the game laws are laws of the state and the federal government does not? What interests me most, but not casino games or online paris exercise, but activities that friends in. For example, for me it's illegal to play cards for money at a friend's house? Is it illegal, a fantasy football league with a buy-in is charged with organizing the winner (s). Is it illegal to attend a support group for the NCAA tournament with a buy-in? Strictly speaking, we use the Internet to transfer in the last two, but not the money, but only the creation of the Federation or the pool. I know he is not really important if these activities are legal or not, is not applicable, and does not deal with questions of morality, if I violate the law. What worries me is that I "must be cautious" with such activities, such as tax payments does not explain in a forum, or send an e-mail about poker games?
