A lottery is a scheme for the distribution of prizes by chance. While making decisions and determining fates by casting lots has a long record in human history—including several instances in the Bible—using lotteries for material gain is more recent, with the first recorded public lottery being organized in Rome by Augustus Caesar to fund municipal repairs. Later, Roman emperors gave away property and slaves by lot as an entertaining amusement during Saturnalian feasts. During the American Revolution, the Continental Congress used lotteries to raise money for the colonial army and, at its conclusion, state governments adopted them as a popular and effective means of raising funds for various projects.
A financial lottery is a game where participants pay a small amount of money, select a group of numbers or have machines randomly spit out numbers, and win large cash prizes if enough of their numbers match those selected by the machine. This type of lottery is also common in sports, with teams selecting players for their playoff rosters based on the number they receive from the random selection process. The concept of a draft lottery was popular in the United States during the Vietnam War, where lottery-style drawing was used to determine conscripts for the military.
Some people use the term to refer to any scheme for distributing goods or services that depends on chance rather than merit, but this is less accurate. Governments use a variety of methods for allocating scarce resources, and many of these are not considered lotteries because the winnings do not depend on chance or skill but rather on the relative wealth of applicants or competitors.
