In the state of Minnesota, home poker games are an accepted form of gambling. Minnesota state law specifies that “Social bets are allowed only if they are done in a private social setting”. Social gambling is only illegal when it pertains to “organized, commercialized, or systematic gambling”, or when the owner/host of the residence profits in some way from the home poker game other than actual gambling profits from playing the card game.
