The jackpot in tomorrow (Saturday) night’s Powerball game is estimated at an even 100-million dollars, which Iowa Lottery spokeswoman Mary Neubauer predicts will bring ticket buyers out in droves. She says people have different levels at which they start to play.Neubauer says for some reason, Powerball players get very excited when the jackpot hits that magic nine-digit number. Neubauer says this 100-million dollar drawing is the new face of Powerball after changes that were made last summer. She says those changes were made with the expectation that there would be more big jackpots.It was just a month ago that Powerball ticket-buying peaked when the game’s largest-ever jackpot hit 314-point-nine million dollars, a prize that was claimed by a West Virginia man.
