SANDY, Utah -- A 27-year-old stay-at-home mom from Sandy, Utah, has become the first person to win $1 million on NBC's "Deal or No Deal."

Jessica Robinson used a simple strategy to become the top winner in the show's three-year history.

That plan was to stick to case number four because there will soon be four in her family.

Robinson, who already has one child, was nearly 30 weeks pregnant when the show was taped in Los Angeles on July 9. The show aired Monday night.

The Robinsons plan to move to Austin, Texas, where her family lives.

Ross Robinson plans to get a newer truck and start a window-cleaning business.

Much of the money will be socked away for their children's education and other family savings.
