Winning $50,000 Powerball ticket sold in Tucson

The Associated Press has learned that the group that runs Powerball approved, then backed off, changes that would have given ticket buyers more bang for their two bucks than the game redesign implemented last year. In October, Powerball managers changed the game's matrix in a bid to build bigger jackpots to revive lagging player interest and ticket sales. (AP Photo/Tony Dejak)</p>
