(NEW YORK) -- One sole winning jackpot ticket was sold in a Speedway convenience store in Des Plaines, Illinois, in a historic $1.34 billion drawing, according to Mega Millions.
One ticket matched all six numbers in Friday night's drawing. The winning numbers were 67, 45, 57, 36, 13 and the mega ball was 14.
The jackpot was initially estimated to be $1.28 billion, but had officially grown to $1.34 billion due to last-minute sales, Illinois lottery director Harold Mays said at a press briefing on Saturday.
The prize is the equivalent of $780 million in cash, he said.
Mega Millions has yet to hear from the winner, Mays said.
"We don't know whether they even know that they won a prize. So I encourage everybody to check your ticket," he said, noting that it could take a few weeks for a winner to come forward to "get their affairs in order."
The winner can opt to remain anonymous, he said.
The Speedway will receive $500,000 for selling the winning ticket, according to Mays.
For only the third time in the 20-year history of the American lottery game, the big prize has reached the billion-dollar mark. The jackpot has grown to an estimated $1.28 billion -- a cash value of $648.2 million -- after no ticket matched all six numbers drawn Tuesday night, according to a press release from Mega Millions.
This is the second-largest jackpot in Mega Millions history, behind only the record $1.537 billion won in South Carolina on Oct. 23, 2018 -- the world's largest lottery prize ever won on a single ticket.
"We are thrilled to have witnessed one of the biggest jackpot wins in Mega Millions history. We're eager to find out who won and look forward to congratulating the winner soon!" Ohio lottery director Pat McDonald, currently serving as lead director for the Mega Millions Consortium, said in a press release.
The jackpot has reset to $20 million for Tuesday's drawing.
Friday night's Mega Millions drawing marked the 30th in this jackpot run, which began on April 19.
In the 29 drawings since the Mega Millions jackpot was last won in Tennessee on April 15, there have been over 28.1 million winning tickets at all prize levels, including 42 worth $1 million or more in 17 states across the country. Four Mega Millions jackpots have been won so far this year -- in California, New York, Minnesota and Tennessee.
Mega Millions jackpots start at $20 million and grow based on game sales and interest rates. Despite a surge in ticket sales, the odds of winning the big prize remain the same -- 1 in 303 million.
Mega Millions tickets are $2 and can be purchased in 45 U.S. states, Washington, D.C., and the U.S. Virgin Islands. Drawings are conducted at 11 p.m. ET every Tuesday and Friday at the studios of Atlanta ABC affiliate WSB-TV, supervised by the Georgia Lottery.
Winners can either take the money as an immediate cash lump sum or in 30 annual payments over 29 years.
