The Multi-State Lottery Association (MUSL) is an American non-profit, government-benefit association owned and operated by agreement of its 34-member lotteries. MUSL was created to facilitate the operation of multi-jurisdictional lottery games, most notably Powerball.
MUSL was formed in December 1987, by seven U.S. lotteries. Its first game was launched in February 1988, Lotto America. That game was changed to Powerball; its first drawing was in April 1992. Powerball was a unique game using two drums, suggested to MUSL by Steve Caputo of the Oregon Lottery.
