No one has matched the jackpot-winning numbers in Wednesday night's Powerball drawing, and the prize has increased to an estimated $478 million.
The next drawing will be Saturday. Nearly three months have passed without a winner of the big prize.
The chance of winning the Powerball is incredibly small, at 292.2 million-to-1. But players have much better odds, of about 1 in 25, of winning smaller prizes ranging from $4 to $1 million.
