No. According to Section 53-278a, poker is listed as one of the forms of gambling that are illegal in Connecticut.
Section 53-278b exempts from prosecution and punishment people who gamble “incidental to a bona fide social relationship” as long as no one other than the participants receives anything from the game. Both the Department of Consumer Protection and the Attorney General have determined that the hosting of poker games or tournaments at commercial bars or similar establishments would violate Connecticut law.
Poker can be played legally at the two tribal casinos.
