A lottery is a game in which tickets are sold for a chance to win a prize based on the drawing of lots. It is a popular form of gambling. Lotteries are legalized in many states and are governed by state laws. Prizes are often cash or goods. Some states prohibit the sale of lottery tickets, while others require the establishment of a state agency to oversee the operations. State-sponsored lotteries are often considered to be legal forms of gambling, and their profits may be taxed.

The word “lottery” is derived from the Dutch noun “lot” (“fate”), which in turn is a diminutive of the Dutch verb “loet” (“to choose”). In English, the term was first recorded in the 15th century, and is thought to be a calque on the French word loterie, itself a calque of Middle Dutch lotinge, meaning “action of choosing by lot.”

Lottery games were once widely used in Europe as early as the 16th century, and were often a part of dinner parties or other public celebrations. In those days, the prizes were generally fancy items of unequal value. Later, the lottery became an important source of funds for various public works projects in both the private and public sectors. Lotteries played a significant role in the founding of the American colonies, and they were used extensively in colonial-era America to finance roads, canals, and wharves, as well as churches and universities. Benjamin Franklin sponsored a lottery to raise funds for cannons for the defense of Philadelphia against the British during the American Revolution.

In the United States, the modern state-sponsored lottery was established in New Hampshire in 1964. Inspired by this success, most of the other states followed suit in a short period of time.

Currently, 37 states and the District of Columbia operate state lotteries. Each lottery is run by a state agency or public corporation, and it typically begins operations with a modest number of relatively simple games. Over time, in response to pressure for additional revenues, the lottery progressively expands its portfolio of games.

Although the games vary from one state to another, most lotteries use fixed prize structures, with a single large prize, and several smaller prizes, which are awarded for specific combinations of numbers. The prizes are based on the total value of tickets sold, which is calculated after the costs of promotion and any taxes or other revenue are deducted. The size and complexity of the prize pool are often a major issue in state lotteries, because they tend to attract people with high expectations for winning big.

A number of critics charge that state lotteries are unnecessarily expensive for the public, and that they promote gambling among certain groups of the population. They note that the majority of lottery players are from middle-income neighborhoods, and that lower-income individuals participate at much lower rates. They also argue that the legislature’s earmarking of lottery proceeds for a particular purpose, such as public education, does not necessarily increase overall funding for that program.
