A Powerball ticket sold in Black Hawk is worth $50,000 in the latest drawing.
South Dakota lottery officials say the ticket matched four of five white ball numbers and the Powerball in Saturday's drawing to win the game's third prize, at odds of 1 in about 913,000.
The winner has about six months to claim the money.
Powerball is played in 44 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands. The jackpot is at $60 million for Wednesday's drawing.
