[Update on Friday] The estimated jackpot for Friday's Mega Millions drawing has risen to $640 million, lottery officials said Friday.
[Posted at 1:57 p.m. ET Thursday] The estimated jackpot for Friday night's Mega Millions drawing rose Thursday to $540 million, extending what Mega Millions officials say already was going to be a world record for lottery jackpots.
Friday's jackpot initially was estimated at $476 million, and then $500 million, but stronger-than-anticipated sales nationwide have helped push up the figure, lottery officials said.
The previous world record for a single jackpot, according to Mega Millions officials, was that game's $390 million prize in a March 6, 2007, drawing. That jackpot was split by winners in Georgia and New Jersey.
The growing jackpot has drawn plenty of interest from would-be millionaires.
In Texas, one of the 42 states where Mega Millions is played, 482,763 standard $1 tickets - that is, tickets without the extra $1 Megaplier option - were sold from 11 a.m. to noon on Thursday, said Kelly Cripe, spokeswoman for the Texas Lottery Commission. In the same hour a day earlier, 143,605 tickets were told in Texas, Cripe said.
Mega Millions officials predict that $396 million in tickets will be sold nationwide from Wednesday through Friday's drawing, Cripe said. The estimate includes actual sales from Wednesday.
On Wednesday, lottery officials in Virginia estimated that the number of tickets sold in that state on Friday alone would be more than four times the 1.2 million tickets sold in Virginia on a Friday two weeks earlier, when the jackpot was $200 million.
"Sales are very, very strong in Virginia. It looks like we're seeing a lot more people who don't normally play want to get in the game," Virginia Lottery spokesman John Hagerty said Wednesday afternoon.
Friday's $540 million prize would be payable as an annuity over 26 years. If a winner prefers, he or she could choose a one-time, lump-sum payment, which in this case would be $389 million. Both figures are before taxes.
Friday's jackpot rolled over from Tuesday's drawing for a¬†$363 million prize, which no one won.¬†The prize has been building since January 24, when a Georgia woman won a $72 million Mega Millions drawing.
The biggest single-ticket win in the other nationwide lottery, Powerball, was in February 2006 when a¬†ticket held by eight workers at a Nebraska food plant paid a $365 million jackpot.
Mega Millions is played in 42 states plus the District of Columbia and the U.S. Virgin Islands.
A jackpot-winning ticket must match all five numbers drawn from a pot containing 56 balls and then match the Mega Ball, which is drawn from a pot containing 46 numbers. Odds of winning are almost 176 million to 1. Each regular ticket costs $1.
Jackpots start at $12 million and rise for subsequent drawings when jackpot-winning tickets aren't sold.
