The estimated Mega Millions jackpot has risen to $449 million, making it potentially the 7th largest lottery jackpot in the U.S. If any ticket matches the b*lls drawn Tuesday, the jackpot will be the largest since a $448.4 million Powerball prize won by a New Jersey family May 7. The highest jackpot drawn in the country was a $1.6 billion Powerball jackpot won in January by players in three states. The odds of picking the correct numbers on five white b*lls and one yellow ball in the Mega Millions game are one in 259 million. The drawing will take place at 10 p.m. Central time.
