| On February 26, 2013, then State Governor Chris Christie signed Assembly Bill 2578, legalizing online gambling in the state. Shortly thereafter, the first ever fully legal gambling sites in New Jersey officially went live. New Jersey was among the first states along with Nevada and Delaware to legalize online casinos If you’re 21-years-or-older and are physically located in New Jersey, you can sign up and play at online casinos and online poker sites that are operated by the Atlantic City casinos themselves. You don’t even have to be a resident of the state. All that is required is that you are physically located in New Jersey when you log on.
