An $856 million Powerball jackpot is on the line Saturday night, up $70 million from Wednesday’s drawing. The jackpot is the largest since last year’s $1.8 billion prize won in Arkansas on Christmas Eve. It was last drawn on Wednesday’s drawing. The jackpot is now the eighth-largest Powerball jackpot in the game’s history. So far this year, there have been seven jackpot winners, with the last jackpot won on May 2 by two tickets in Florida and Texas.
