Pennsylvania casinos rolling out around the clock online gambling

Online casino-style gambling is now available around the clock in Pennsylvania.

The Pennsylvania Gaming Control Board said Thursday that three casinos passed this week's tests to begin operating online gambling portals 24 hours a day, daily, for patrons statewide who are at least 21 years old.

Nevada, New Jersey and Delaware are the only other states where online casino gambling is legal.

Parx Casino in suburban Philadelphia, Penn National's Hollywood Casino near Hershey and SugarHouse Casino in Philadelphia are now operating online casino games on websites and mobile applications under a 2017 Pennsylvania law that authorized an aggressive expansion of gambling.

The casinos expect to roll out poker at a later date.

Pennsylvania is the nation's No. 2 state for commercial casino revenue, behind Nevada, at $3.2 billion last year.
