HARRISBURG, Pa. (AP) — Online casino-style gambling is now available around the clock in Pennsylvania. Regulators said Thursday that two casinos passed this week’s tests to begin operating online gambling portals 24 hours a day for patrons statewide who are at least 21 years old. Nevada, New Jersey and Delaware are the only other states where it is legal. Parx Casino and Penn National’s Hollywood Casino are now operating online casino games on websites and mobile applications.
