At least six Pennsylvania casino operators have filed applications to offer online gambling ahead of Monday’s initial licensing round deadline.

In April, the Pennsylvania Gaming Control Board (PGCB) invited its 13 brick-and-mortar casino licensees to apply for multi-vertical (slots, table games, poker) online gambling licenses, which were available for $10m. But well into July, the PGCB had yet to receive a single application.

On Friday, the dam broke with news that the operators of the state’s market-leading Parx Casino, the Mount Airy Casino Resort in the Poconos and the as-yet-unbuilt Live! Hotel & Casino in South Philly had submitted applications.

While the PGCB won’t release full details until Tuesday, the Pittsburgh Post-Gazette reported that operators of Pittsburgh’s Rivers Casino (pictured), the SugarHouse in Philadelphia (which already operates the PlaySugarhouse.com site in neighboring New Jersey) and the Hollywood Casino in Dauphin County had also joined the application parade.
