Online gambling is concsidered a misdemeanor in CT. CT also recognizes the difference between games of skill and games of chance (i.e. poker is a game of skill and roulette is a game of chance.)
Though it is unlikely anyone would care that you are online gambling but careful about 2 things. Check the reputation of the site you are joining to make sure they are not scammers and check out how the money goes in and out. If you cannot get your money out it won't matter how much you win.
