The Mega Millions jackpot hasn’t been won since late October and it is now estimated at 640-million dollars for Friday’s drawing. The Minnesota Lottery’s Marie Hinton says it’s not generating as much buzz as the two-billion-dollar Powerball in November, but ticket sales are on the rise:

“Oh absolutely even with a game that’s a littler lesser known in Minnesota when you see 640 million who wouldn’t want to start out the new year with something like that.”

Hinton says sales typically grow as the jackpot gets larger.  A Minnesota couple won a 106-million-dollar Mega Millions jackpot in April and took the 67-million-dollar cash option.
