Powerball is an American lottery game sold by 47 lotteries (44 states plus the District of Columbia, Puerto Rico and the U.S. Virgin Islands) as a shared jackpot game. It is coordinated by the Multi-State Lottery Association (MUSL), a non-profit organization formed by an agreement with various U.S. lotteries. Since the format change on January 15, 2012, Powerball's minimum advertised jackpot is $40 million (annuity) with a potential of nine-figure prizes.
