DES MOINES, Iowa (AP) -- Powerball officials say the jackpot has climbed to an estimated $600 million, making it the largest prize in the game's history and the world's second largest lottery prize.
Lottery officials say the prize is growing quickly Friday because so many people have been purchasing the $2 tickets.
The jackpot has jumped by an estimated $236 million since the last drawing on Wednesday. The last jackpot was won on March 30, so it's been steadily growing for about six weeks.
The next drawing is Saturday night. The largest jackpot ever was a $656 million Mega Millions prize won in March 2012.
The prize was split three ways with winners in Illinois, Kansas and Maryland. Odds of winning the Powerball jackpot are about 1 in 175 million.
Oregon Lottery spokesman Chuck Baumann said for each $2 ticket sold, $1 goes to fund the jackpot, $1stays in the state. From that, 68 cents go into the state's genera; fund and 32 cents cover administrative costs.
The retailer that sells the winning ticket gets $100,000.
