The winning ticket was purchased at a Speedway gas station in Des Plaines, roughly a 20-mile drive northwest of downtown Chicago, the Illinois Lottery said Saturday.
“We have not heard from the winner yet. We don’t know whether … they even know that they won a prize. So I encourage everybody to check your ticket,” Illinois Lottery Director Harold Mays told reporters Saturday morning in Chicago.
If the holder chooses a lump-sum cash option, the ticket will yield a one-time payment of about $780 million. Otherwise, the nearly $1.34 billion prize will be spread over an initial payment and 29 annual payments.
Friday night’s winning numbers were 13, 36, 45, 57, 67 and a Mega Ball of 14.
The Speedway convenience store in Des Plaines will receive $500,000 for selling the winning ticket, Mays said.
The jackpot winner has a year from the drawing to claim the prize, Mays said.
The largest jackpot of any US lottery game was $1.586 billion — a Powerball prize from January 13, 2016, shared by winners in California, Florida and Tennessee.
Other tickets win big prizes
Some other ticket holders also won some sizable prizes 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 the buyers matched not only the first five numbers, but also paid an additional $1 to activate the game’s “multiplier,” which elevates non-jackpot prizes.
First MegaMillions jackpot win since April 15
The Mega Millions website on Friday night became inaccessible for several minutes after the drawing. The lottery’s jackpots start at $20 million and grow based on game sales and interest rates, according to its website.
The next drawing will be Tuesday at 11 p.m. ET, at the $20 million starting point.
Mega Millions tickets are sold in 45 states, Washington, DC, and the US Virgin Islands, where drawings are on 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 that state.
