A Mega Millions lottery ticket that contained all the winning numbers — bought along the western edge of the Chicago metro area, in DeKalb County — has made someone in Illinois $344 million richer this week.

It was a lucky night for a Mega Millions player in Illinois who bought the winning ticket, worth an estimated $344 million. This is the first time the Mega Millions jackpot has been won since Jan. 17, when a ticket in Arizona won the $112 million prize. The jackpot will now reset to $20 million ahead of Friday night's drawing.

The most recent big Mega Millions winner was a lucky lottery ticket holder in Arizona, who struck gold on Jan. 18, winning a $113 million jackpot. On Tuesday, the lottery announced mega changes to the game that will more than double the price of a ticket to $5 per play.
