The numbers have been drawn, and Powerball officials say a winning ticket was sold in New Hampshire.
The winning numbers are: 8, 17, 22, 42, 47, Powerball 21.
By the time the drawing took place at 9:59 p.m. Saturday, the jackpot had swollen to an estimated $295 million. That rivals the biggest Powerball jackpot of all time: $295.7 million won in 1998 by a group of factory workers in Ohio.
The richest lottery prize in US history is the $363 million Big Game jackpot that was won last year by two players in Illinois and Michigan.
