The first U.S. multi-state lottery game was formed in 1985 in Maine, New Hampshire, and Vermont; its flagship game remains Tri-State Megabucks. In 1988, the Multi-State Lottery Association (MUSL) was formed with Iowa, Kansas, Missouri, Oregon, Rhode Island, West Virginia, and the District of Columbia as its charter members; it is best known for Powerball, which was designed to create large jackpots. Another joint lottery, "The Big Game" (now called Mega Millions) was formed in 1996 by six lotteries as its charter members.
