Internet gambling is legal in the 48 contiguous states, including Washington, Oregon, Nevada, New Jersey, and Pennsylvania. However, the state of Hawaii and Utah prohibit it, due to their large Mormon populations. In addition, Hawaii has a concern that gambling may affect family relationships. Idaho has no plans to legalize online gambling. Regardless of where you live, you can play online poker and blackjack with real money and get the same great benefits as traditional casinos.
