A big demand for Mega Millions lottery tickets has boosted the jackpot to $521 million for Friday night’s drawing.
A single-winning ticket with the cash prize option would be worth $317.2 million.
The jackpot is the fourth-largest for the Mega Millions game and the 10th largest lottery prize ever offered in the United States.
The drawing comes less than two weeks after a $456.7 million Powerball jackpot was won in Pennsylvania on St. Patrick’s Day, the largest lottery prize ever won in the state.
The ticket was sold at the Speedway gas station in Manheim. The winner has yet to come forward.
Pennsylvania has sold two jackpot-winning Mega Millions tickets since joining the game in 2010. The largest was a $91.8 million cash-value prize claimed by a Virginia man in 2015.
Mega Millions tickets are sold until 9:59 p.m. on drawing nights. A ticket costs $2.
