Home poker games are legal in Maine so long as they standard rules of “social gambling” are upheld. No player or other person may benefit from hosting the event. All profits must come from actual winnings from the poker game. No player may have an advantage over another. Etc, etc, etc… Maine does have strict regulations that prohibit unlawful gambling, but an exception is made for “players” in a “social gambling” situation.
