Powerball officials say the jackpot has now climbed to an estimated $600 million dollars, making it the largest prize in the game's history and the world's second largest lottery prize.
Iowa Lottery spokesperson, Mary Neubauer, says a number that big grabs everyone's attention.
A record Powerball jackpot of 587-million dollars was won in November. Neubauer says the switch from a one-dollar to a two-dollar ticket for Powerball has helped create bigger jackpots more often.
The next Powerball drawing is 9:59 p-m on Saturday. In Iowa, you can buy a ticket for Saturday's drawing up until 8:59 p-m that day.
The odds of winning the Powerball jackpot are about 1 in 175 million.
