Regional casino operator Penn National Gaming (PNG) says it has reopened over 70% of its casinos following their COVID-19 shutdown, but thousands of staff may not be around long enough to celebrate.

On Friday, PNG announced that 30 of its 41 gaming and racing venues have resumed operations after being ordered to close in March to minimize COVID-19 transmission.

The total was boosted Friday by four PNG properties in Ohio and the Hollywood Casino at Penn National Race Course in Pennsylvania. PNG is now welcoming guests to casinos in 13 of the 19 states in which it operates.

PNG CEO Jay Snowden called the news “an important milestone” in the company’s rebound and he thanked state regulators for including gaming in their economic revival plans.
