The winning ticket was purchased at a Speedway gas station in Des Plaines, about a 20-mile drive northwest of Chicago, the Illinois Lottery said. Information about the ticket purchaser was not immediately available Saturday morning.
If the holder chooses a lump sum payment option, the ticket will earn an estimated one-time payment of $742.2 million. Otherwise, the prize of approximately $1.28 billion will be spread over annual payments.
Friday night’s winning numbers were 13, 36, 45, 57, 67 and a Mega Ball of 14. The next draw is Tuesday at 11 p.m. ET.
Some other ticket holders also picked up major prizes on Friday.
Twenty-six tickets won a secondary prize of at least $1 million because they matched the first five numbers.
Six of the 26 tickets won $2 million because buyers not only matched the first five numbers, but also paid an additional $1 to activate the game’s “multiplier,” which boosts non-jackpot prizes.
The biggest jackpot of any US lottery game was $1.586 billion – a Powerball prize from January 13, 2016, shared by winners from California, Florida and Tennessee.
On Friday night, the Mega Millions website became inaccessible for several minutes after the draw. Lottery jackpots start at $20 million and increase based on game sales and interest rates, according to its website.
Mega Millions tickets are sold in 45 states, Washington, DC and the US Virgin Islands, where the draws take place Tuesdays and Fridays at 11 p.m. ET. Tickets are sold online in Georgia, Illinois, Kentucky, Michigan, New Hampshire, North Carolina, North Dakota, Pennsylvania, Virginia and DC, but the purchaser must be in this State.
