USA Casinos Online by State

Las Vegas and Atlantic City are no longer the only place where you can play real money casino games. Delaware and New Jersey were the first state to allow full blown online casino gambling back in 2013. It’s been around a while, but now it’s really kicking into gear as land-based casinos like Borgata and Caesars have started to take online casino gaming more seriously.

The repeal of PASPA (Professional and Amateur Sports Protection Act) to allow online sports betting in the US has certainly helped the online casino business in legal states. NJ and Delaware got company in 2019 when Pennsylvania allowed their first online casinos in BetRivers and Hollywood Casino.
