A competition based on chance, in which numbered tickets are drawn at random to determine the winners of prizes. It is a form of gambling and is typically operated by state governments.

The idea of making decisions and determining fates by casting lots has a long history in human culture, including numerous instances in the Bible. More recently, state lotteries have developed as a popular method of raising funds for government purposes. Almost all states now offer a lottery. Most have laws regulating the operation and promotion of lotteries, with most delegating responsibility to a lottery division in their executive or legislative branch.

A lottery usually involves payment of a consideration in return for the chance to win a prize, which can range from money to jewelry or a new car. Federal law prohibits the marketing or sale of lottery products via mail or over the phone.

Lotteries are widely supported by the public, and studies suggest that their popularity is independent of a state’s financial health. Rather, they benefit from the perception that proceeds are used for public good, a claim heightened by the fact that state governments generally have little control over the distribution of lottery revenues.
