The lottery is a game in which numbers are drawn to win money or prizes. Prizes can include cash, real estate, and even annuities that pay regular payments over time. The lottery is often used to raise funds for public projects, such as roads, bridges, or schools. Public lotteries can be run by government agencies, private companies, or a combination of the two. Private lotteries are typically held for a specific product or service, such as units in a subsidized housing project or kindergarten placements at a public school.

The casting of lots to make decisions and determine fates has a long history, including several examples in the Bible. However, lotteries offering tickets for sale and distributing prize money are considerably more recent. One of the earliest was organized by Augustus Caesar to fund repairs in Rome. Another was the apophoreta, an amusement at dinner parties where guests received pieces of wood with symbols on them and then, toward the end of the evening, had a drawing for prizes that were carried home.

In modern times, the popularity of lottery has increased to a degree where it is now offered in most states and in many countries worldwide. Despite this widespread acceptance, the lottery has been subject to numerous criticisms. These range from complaints about the impact of the gambling on poor people and problem gamblers, to allegations that lotteries encourage the accumulation of wealth by a few at the expense of the masses.
