Meanwhile, the Powerball jackpot for Wednesday has rolled to an estimated annuity of $345 million.

"Lotteries are in the fun and games business, and who wouldn't have fun thinking about nearly a billion dollars in prizes?" Mega Millions Lead Director Gordon Medenica said.

The current Mega Millions jackpot has been increasing since it was last won July 24, when 11 coworkers in California shared $543 million. The last Powerball jackpot of $245.6 million was won by a New York man August 11.
