"I've never played Powerball, but my husband plays a lot, so I bought a ticket while I was at the store," Robinson said.
The first-time player discovered the next day that she had matched four white balls and the Powerball in the drawing, earning a $50,000 prize that was doubled to $100,000 thanks to the Power Play option.
"The day after the drawing, my husband checked the ticket and started yelling, 'We won! We won!' I thought he was joking and that there was no way we'd won big the first time I bought a Powerball ticket. It was a surreal feeling when I looked the ticket over and saw that we really did win," the winner recalled.
Robinson said she plans to buy a house with her prize money.
