According to the lottery Web site, the winning ticket was sold in Suffolk County, at Cards & Things on Rt. 25A in Rocky Point.
Sonny Zaveri is the store's owner.
"I said, 'Wow!' I couldn't believe it," he said.
Sonny says he has no idea who the lucky winner is, but "lucky" doesn't begin to describe it.
Your odds of winning even ten dollars are 844 to one. To win 150 dollars, it's 14-thousand to one. To win 10-thousand dollars, you'd have to beat odds of 690-thousand to one. Your chances of winning 250-thousand are 4 million to one.
Winning the Mega jackpot is an astronomical 176-million to one.
According to one analysis, you are nearly four times more likely to die in an automobile accident on your way to buy your Mega Millions ticket than you are of winning the jackpot.
The store's owner wonders whether the winner is one of his regular customers, but whoever it is he's hoping it's not just someone who wants the money.
Lottery spokeswoman Jennifer Givner says the ticket shows a lump-sum option, meaning the cash would be paid out right away instead of $162 million over 26 years.
But there's a catch: The prize then shrinks to about $100 million.
Mega Millions tickets are sold in Georgia, Illinois, California, Texas, Washington, Virginia, Ohio, New York, New Jersey, Michigan, Maryland and Massachusetts.
The winning numbers are 3, 33, 35, 39, 45 and the mega ball number is 13.
