Rae Ann Wentworth-Cadieux, of Hadley, chose her numbers based on a convenience store chain 7-11 and race cars, the Massachusetts State Lottery said.
The winning numbers were 7, 10, 11, 13, 24, with the Powerball number 24.
Wentworth-Cadieux got all the numbers but missed the Powerball. She said she plans to buy a summer home with her winnings. She purchased her ticket at Pride Station & Store, 445 Russell St. in Hadley.
Jan Busby, of Norfolk, also had a system. She used her family members' birthdays to choose her numbers, the lottery said.
Busby rarely plays the lottery but said she bought a ticket because the prize purse was so high.
She purchased her ticket at Shaw’s Supermarket, 255 East Central St. in Franklin.
The third $1 million prize winner in Massachusetts had not come forward, but the ticket was sold at Global Montello/Gulf, 821 Main St. in Waltham.
The stores that sold the winning tickets will receive a $10,000 bonus.
