One lucky person out there could be the winner of the Powerball jackpot tonight.
That jackpot is now up to 500 million dollars for tonight's 10 o'clock drawing.
You can pick up tickets at lottery retailers in Iowa, Nebraska and South Dakota to take your chance at the jackpot.
The odds of winning it all aren't great though, 1 in 259 million.
"As we came back to Sioux City, this is where we're from. I'm buying them as I go," said Delores Soule. "I have six grand children and eight nine great grand children to spoil. So if I win it, that's where it's going."
The estimated jackpot has gone up 100 million dollars since the last drawing on Saturday, because so many interested people are buying tickets looking to strike it rich.
