A lottery is a form of gambling in which tickets are sold and winners are chosen by drawing. Most states regulate lotteries and the profits are used for state government programs. In the United States, most lotteries are monopolies controlled by state governments. Ticket sales are restricted to residents of the regulating states, although many games can be played online.

The word “lottery” derives from the Latin phrase lutra rota, meaning “roll of lots.” Ancient people used to draw numbers for a variety of reasons, including giving away land and slaves. In the 1740s, Benjamin Franklin organized a lottery to raise money for cannons to defend Philadelphia. George Washington was a manager for Colonel Bernard Moore’s infamous slave lottery, which advertised the prizes in The Virginia Gazette.

In the United States, all state governments have lotteries, which are regulated by their respective legislatures. The state lottery commissions set up, monitor, and run the games. In some states, the commissions have enforcement authority over fraud and abuse. In other cases, enforcement authority may be shared with the attorney general’s office or state police.

Lotteries have long been a popular way for states to increase their revenue without imposing higher taxes on middle-class and working-class people. Most people approve of lotteries, but only about half play them. Lottery enthusiasts argue that the games provide cheap entertainment and help to fund good public projects, such as schools, roads, and hospitals. They also point to the financial benefits of lotteries for small businesses that sell tickets and larger companies that participate in merchandising and marketing campaigns.
