While neighboring New Jersey led the way for a while, the Keystone State quickly grew into a premier destination for online gambling in the USA. New Jersey online casinos were the first to go live in 2013, legally dodging federal legislation by having digital-first operators work off existing Atlantic City licenses.Ģ017 marks the legalization of online casinos in Pennsylvania. Players from these regions can enjoy a range of games, including slots, roulette, blackjack, baccarat, live dealer tables, and more. Online casinos are legal in only six US states, including Michigan, Pennsylvania, New Jersey, West Virginia, Connecticut, and Delaware.
