The winners will split the $355 million jackpot. Another 67 tickets, including 10 in California, had five numbers without the Mega Ball. Those tickets are worth about $250,000.
The prize was the fourth-largest in U.S. history and the second-largest in Mega Millions' history, said Arizona Lottery spokeswoman Cindy Esquer. The lottery's prize of $390 million in March 2007 remains the nation's richest on record.
Fans of the ABC television show "Lost" are having some fun with the jackpot. Four of the six winning numbers matched those that character Hugo "Hurley" Reyes used to win a lottery on the show, only to suffer a series of spectacular misfortunes. Hurley's numbers -- 4, 8, 15, 16, 23 and 42 -- popped up throughout the show.
Mega Millions said 25,587 tickets matched three of the winning numbers, plus the bonus number, so anyone who played the "Lost" numbers won $150 per ticket.
