A Powerball ticket sold at a gas station in western Illinois was the sole winner of the $1 billion jackpot, ending a three-month drought without a top-prize victor.

The ticket that won the jackpot Wednesday night was purchased at a Hy-Vee station in Quincy, about 100 miles (161 kilometers) west of the state capital of Springfield along the Missouri border, Illinois Lottery officials said. The winning numbers were 4-26-66-67-69 with the Powerball number of 9.

It wasn't immediately clear if the winner has come forward yet.

The prize comes in the form of either an annuity of $1 billion paid over 29 years or a lump-sum payment of $450.5 million. Winners almost always take the lump sum.
