While Michelle Kilner was originally tight-lipped about her plans for the money, she has now told the Express & Star that she is to share it equally with four colleagues.
This means each of the five workers, from the Morrisons supermarket in Rugely, are to receive £40,000.
Ms Kilner told the publication: "I won the prize myself and we all paid for our own tickets but when we went in we said we would split whatever we won."
"I'm not tempted to keep it at all, that's what we promised each other and I'm going to stick to it," she added.
The £200,000 national jackpot forms part of a total of £28 million paid out weekly by Gala Bingo, according to the company's website.
