HARRISBURG (AP) — Two more casinos in Pennsylvania are seeking sports-betting licenses.

The Pennsylvania Gaming Control Board said Friday that Mount Airy Casino Resort and Mohegan Sun Pocono have applied for licenses.

Sports books are open at six of Pennsylvania’s 12 casinos and two off-track betting parlors, including SugarHouse Casino in Philadelphia, Harrah’s Philadelphia Casino in Chester, Rivers Casino in Pittsburgh, Hollywood Casino at Penn National Race Course near Hershey and suburban Philadelphia’s Parx Casino and Valley Forge Casino.

A seventh casino, Presque Isle Downs Casino in Erie, has a license, but hasn’t yet opened sports betting.

States are increasingly legalizing sports betting after the U.S. Supreme Court cleared the way last May. A 2017 state law allows Pennsylvania’s casino owners to pay a $10 million fee to operate sports betting.
