A ticket sold in Lennox is worth $250,000 in the latest Mega Millions drawing.
South Dakota lottery officials say the ticket matched all five white ball numbers but missed the Mega Ball on Tuesday to win the game's second prize. The odds of doing so are one in nearly 4 million.
The winner has about six months to claim the money.
Mega Millions is played in 42 states, the District of Columbia and the U.S. Virgin Islands. The jackpot sits at $55 million for the next drawing, on Friday.
