In the seven years since all USA lotteries began selling both Powerball and Mega Millions tickets, both games have never offered prizes so large at the same time. This is the sixth largest jackpot in the game's history.
The next Mega Millions drawing is Friday night and Powerball on Saturday night during the 11:00 pm news on CBS4, South Florida's new home for the Florida Lottery.
In Pennsylvania, tickets for both games are sold until 9:59 p.m. on drawing nights. Lottery officials say this is the first time that the jackpots in Powerball and Mega Millions have simultaneously topped the $300 million mark.
Of course, it's pretty long odds to win just one of this week's drawings - either Saturday night's $356 million Powerball game, or Friday's $382 Mega Millions drawing. Those prizes are based on annuity options, paid over 29 years.
The odds of winning the Mega Millions jackpot with a $1 ticket are 1-in-258.9 million.
Powerball and Mega Millions are played in 44 states, Washington, D.C., Puerto Rico and the U.S. Virgin Islands. Because if you're going to dream of winning a lottery fortune, why not dream of winning two? They came up with 1 in just over 75.6 quadrillion.
