The numbers were drawn Friday night in Atlanta.
Georgia Lottery officials had estimated the jackpot for the Friday drawing at $325 million after no one hit the big prize on Tuesday. They said Friday that increased ticket sales had bumped the prize to about $333 million.
Mega Millions tickets are sold in Georgia, Illinois, California, Texas, Washington, Virginia, Ohio, New York, New Jersey, Michigan, Maryland and Massachusetts.
The new Mega Millions jackpot is estimated at $12 million for Tuesday's drawing.
