WASHINGTON-The Powerball jackpot grew to $422 million before an 11 p.m. EDT drawing on Wednesday, making it the eighth largest in the game’s history and the 11th-biggest lottery prize ever in the United States. The jackpot amount has now rolled over 22 times since it was reset to its starting sum of $40 million for a drawing on May 11, lottery officials said. The Powerball game is based on lottery tickets sold for $2 apiece. It is played in 44 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands.
