A winning ticket has been sold for a United States lottery jackpot of US$1.22 billion ($2.17 billion), its organiser said on Saturday, one of the largest prizes in the history of the gambling game.
The ticket was sold in the state of California, Mega Millions said, after the winning six numbers were announced on Friday night.
The identity of the winner is not yet clear. It is also unclear whether they are aware they hold the jackpot ticket and are coming forward to claim their prize.
They bought the ticket at a gas station in the town of Cottonwood, about 210km north of the city of Sacramento, Mega Millions said.
The winning numbers were: 3, 7, 37, 49, 55 and 6.
