Overview
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.
Powerball/Mega Millions cross-selling
On October 13, 2009, MUSL signed an agreement with the consortium of states that operated the similar Mega Millions lottery, which allowed MUSL members to sell Mega Millions tickets and consortium members to sell Powerball tickets. On January 31, 2010, all but 2 of the 12 Mega Millions consortium lotteries began selling Powerball tickets. The consortium members did not join MUSL; they were licensed by MUSL to sell Powerball, and the consortium coordinates their Powerball participation with MUSL. Likewise, MUSL members may offer Mega Millions through a special MUSL product group that coordinates with the Mega Millions consortium.
Before the agreement, the only places that sold both Mega Millions and Powerball tickets were retailers that sat on state lines and offered multiple lotteries; one retailer on U.S. Route 62 straddling Sharon, Pennsylvania and Masury, Ohio sold both Mega Millions (via the Ohio Lottery) and Powerball (via the Pennsylvania Lottery) before the agreement and continues to be the only retailer to sell tickets for both states' lotteries.
