LAS VEGAS - Marsha Haworth of New Sharon, Iowa, had no idea that her afternoon walk to the Flamingo Las Vegas resort today would result in a $774,342.17 win on a Wheel of FortuneĀ® IGT progressive slot machine.

Haworth, a 49-year-old administrative assistant to the president of Indian Hills Community College in Ottumwa, Iowa, said she usually walks four or five miles a day for exercise and records her steps on a pedometer. She was walking along The Las Vegas Strip when she stopped at the Flamingo. Haworth invested just six quarters and a minute of her time before she lined up three "Wheel of Fortune" symbols on the slot machine's center line to win the jackpot at 1:03 p.m.

"I just sat and looked at it," she said of the winning combination. "I remained calm, but it still does not seem real. The first thing I wanted to do was call my husband and tell him." Her husband Allan grows corn and soy beans on their farm in New Sharon.

Haworth is visiting Las Vegas for a regional convention of the Association of Community College Trustees. She serves as secretary to the Indian Hills Community College Board of Trustees. When asked about her plans for the winnings, Haworth said she plans on investing, paying bills and buying her husband a new pick-up, but is not sure which she will do first.

The mother of three grown children, Haworth has been playing slot machines for about 15 years. But the largest jackpot she had won before today was $1,000.

This was the 202nd Wheel of Fortune jackpot since the progressive's inception by International Gaming Technology in December 1996. The progressive jackpot for the three-coin, three-reel, 25-cent slot machine will be paid by IGT in 20 annual payments of $38,717.10. Haworth received her first check in that amount today. The Wheel of Fortune progressive jackpot typically is won on a weekly basis in Nevada, and is reset to $200,000 after each win. The largest jackpot ever won on a Wheel of Fortune progressive slot machine was $7.6 million.
