Overview

• Tammy Carvey, 45, of Wyandotte bought a ticket online for the Sept. 6 Powerball drawing after the jackpot topped $1 billion.
• She matched four white balls plus the Powerball, and the Power Play option doubled the non-jackpot prize from $50,000 to $100,000.
• Carvey initially believed she had won $50,000 before her Michigan Lottery account confirmed the Power Play boost.
• She told the lottery she plans to pay off her home and save the remainder after claiming the prize.
• The Michigan case follows a Virginia winner, Carrie Edwards, who also used ChatGPT to select numbers and won $150,000, which she donated to charity.
