Nobody won the big Powerball jackpot last night worth 103-million dollars, but three tickets sold in Iowa matched five of the six numbers. Those 100-thousand dollar winners were sold in Dubuque, Nevada and Waverly. The Lottery’s Mary Neubauer says yesterday was a busy day.About 917-thousand Powerball tickets were sold yesterday alone in Iowa. That’s a rate of about one thousand every minute statewide. Neubauer says the size of the jackpot grew with the frenzy of ticket sales. It had only been estimated around 100-million dollars, but that changed as sales increased.With no big winner last night, the jackpot drawing Saturday night will grow significantly.The Saturday night drawing should be worth at least 120-million dollars.
