The numbers drawn Friday were 28, 30, 39, 59 and 70, and the Mega Ball was 10. Now the Mega Millions jackpot resets to $40 million for the next drawing on Tuesday.
This winning Mega Millions jackpot comes as the Powerball jackpot is also at a historic level.
The two jackpots together topped $1 billion after going months without a victor.
The biggest Powerball jackpot ever won was $590.5 million claimed by one ticket-holder in Florida in 2013.
The total of the two lotteries is the third largest in the history of the games.
"The retailer will receive a $100,000 bonus commission for selling the jackpot-winning ticket", the Florida Lottery said in a news release early Saturday.
The average American spends about $200 a year on lottery tickets, although residents of some states spend far more. Puerto Rico participates in Powerball. However, under Florida law, the person can not remain anonymous.
In 2013, an 84-year-old Zephyrhills woman was the victor of the largest single jackpot in American lottery history, valued at $590.6 million.
Now, the Powerball jackpot is king at $570 million for the Saturday night drawing.
The odds of a single ticket hitting all six numbers in the Powerball are 292 million to 1, the Multi-State Lottery Association says.
The odds of winning the Mega Millions jackpot are one in 302.5 million.
