Lottery is a game of chance in which numbers are drawn to determine the winner of a prize. Prizes may be money or goods. Many countries have state-run lotteries. People purchase tickets for a small sum of money in order to have a chance at winning. The odds of winning vary wildly, depending on how many tickets are sold and how many numbers are drawn.

Making decisions and determining fates by the casting of lots has a long history (see here for an early account). But lotteries that distribute prizes in exchange for a ticket are of more recent origin, although they have grown to be remarkably popular.

In the United States, the first state-sponsored lottery was introduced in New Hampshire in 1964. The lottery quickly spread to other states, where it is now widespread. State governments justify introducing lotteries by explaining that they are an effective way to raise money for a wide range of public projects without increasing taxes. This arrangement has been remarkably successful, even though there are obvious problems: convenience store owners and other vendors quickly become well-established; lotteries attract high-income players; and the revenues that are earmarked for schools and other public services can be subject to inflation.

Some people prefer to take the lump-sum option, receiving one payment that is a discount on the headline amount, ranging from 45% to 55%. Other winners opt to receive the prize in annual payments that increase each year by 5%. This arrangement can take three decades to reach the final payout.
