A previous referendum in 1974 that sought to legalize casino gambling across the state was defeated. History was made on when the first casino, Resorts International, opened for business in Atlantic City. On that day, a state-wide referendum voted 1.5 million in favor against 1.14 million opposed to the legalization of casino gambling in Atlantic City, New Jersey. The gambling landscape in NJ changed forever on Nov. Atlantic City is #1 casino destination in the Garden State offering top class resorts with slot machines and live table games.
