Wyoming home poker games are legally acceptable by Wyoming Statues definition of Gambling, which provides exceptions for “any game, wager or transaction which is incidental to a bona fide social relationship, is participated in by natural persons only, and in which no person is participating, directly or indirectly, in professional gambling.” Professional gambling would require someone to profit indirectly from the actual game, by charging an admission fee, taking a portion of the pot(s), etc.
