In the United States, lotteries are run by 47 jurisdictions: 44 states plus the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Lotteries are subject to the laws of and operated independently by each jurisdiction, and there is no national lottery organization. However, consortiums of state lotteries jointly organize games spanning larger geographical footprints, which in turn, carry larger jackpots. Two major lottery games, Mega Millions and Powerball, are both offered in nearly all jurisdictions that operate lotteries, and serve as de facto national lotteries.
When Texas joined Mega Millions in 2003, it began offering an option, initially available only to Texas Lottery players, known as the Megaplier, which was similar to Powerball's Power Play. The 11 Mega Millions lotteries without Megaplier on the January 31, 2010 cross-selling date gradually added the multiplier option; by January 2011, all Mega Millions lotteries, except for California, offered the Megaplier. The Texas Lottery owns the trademark to Megaplier.
