Lottery is a competition based on chance in which numbered tickets are drawn at random to win prizes, usually money. The prize money may be a lump sum or annuity payments spread over a few years. Typically, the winner is required to pay tax on his or her winnings. Lottery is a popular form of entertainment and a form of gambling. It is often viewed as a harmless form of recreation, although some have found that it can be addictive.

Lotteries were introduced to the United States in the late 18th century and became a popular method of funding public projects and services. They were also viewed as a painless alternative to taxes for the poor. However, a number of studies have shown that lottery play imposes a disproportionate financial burden on those with lower incomes. It has also been shown that those who win large amounts of money tend to spend their new wealth at a faster rate than those who do not.

A state lottery is a type of gambling game run by a government agency to raise funds for public purposes. In most cases, a fixed percentage of the money collected is allocated to various categories of prizes. The remainder is used to cover operating expenses and administrative costs. If the total prize money is greater than the expenses, a larger percentage of the prize money can be awarded to winners. This is known as a multi-tiered lottery.
