In fact, there has been set up an advanced system to ensure enforcement of this rule requiring players to be located in NJ when gambling at NJ online casinos. If you aren’t in NJ as the time of play, you won’t be able to access online casino sites in New Jersey for real-money play. Just to be clear, you don’t have to be an NJ resident to gamble at NJ gambling sites, you just have to be physically located in the state when you play. Anyone interested in online gambling and physically based in New Jersey, including non-residents, can gamble at any NJ online casino. The general rule is that you can’t play at an NJ online casino while you’re out of the State, either for work or travel. First, you must make sure you’re physically located in New Jersey.
