The woman went into Jewel-Osco, at 696 Northwest Hwy in Cary, to buy some scratch-off lottery tickets, the Illinois Lottery said.
"As I looked over the other options, this ticket stood out. It was as if my vision blocked out all the other tickets-this one was meant to be," said the winner, who chose to remain anonymous under the nickname Wishing Fish.
The woman picked a Ultimate Bonus Payout scratch-off ticket. She won $1 million on the $10 ticket.
"I was at home eating a chocolate bar with the song 'Money' by Pink Floyd playing in the background. I scratched the last symbol and immediately FaceTimed my son, repeating over and over, 'I'm going to have a heart attack-I just won $1 million'," she said.
She said she plans to share the money with 15 family members and her three grown kids.
"I want to buy a car with a sunroof and take a vacation somewhere in the Keys with my husband where I can swim with dolphins-just a few things on my bucket list," she added.
