The Powerball jackpot is now worth $415 million or nearly $269 million in cash.
It increased again after no winning tickets were sold for Wednesday’s Powerball.
There have been 18 drawings in a row with no winner.
The amount has been growing since March 2, after a Florida man claimed the previous jackpot of more than $291 million.
The next drawing is Saturday, May 7.
The Pennsylvania Lottery remains the only state lottery that designates all of its proceeds to programs that benefit older residents. Winners in the state have one year from the drawing date to claim prizes.
