A lottery is a game of chance in which participants purchase tickets and hope to win a prize, which may be money or goods. The term is most commonly used to describe state-run games, although privately run lotteries are also common. In the United States, the lottery is a popular form of gambling and a source of revenue for state governments.

The earliest records of lotteries date to the 15th century in the Low Countries, where towns held public lotteries to raise money for town fortifications and to help the poor. Private lotteries have been around much longer, including a scheme proposed by Benjamin Franklin to raise funds for cannons during the American Revolution.

Since state lotteries are businesses aiming to maximize revenues, advertising focuses on persuading target groups to spend their money. Critics charge that this promotion of gambling can have negative consequences (e.g., for the poor and problem gamblers) and may put state lotteries at cross-purposes with the public interest.

Many people try to increase their chances of winning the lottery by buying more tickets. They often hear tips about picking hot and cold numbers, avoiding Quick Picks and selecting certain combinations. These suggestions usually have little foundation in probability theory, and they tend to be misleading. They also ignore the fact that it is important to have a long-term strategy and budget for your purchases. The most effective way to understand the odds of winning is to apply combinatorial math and probability theory to the lottery.
