A lottery is a type of gambling in which numbers are drawn to win prizes. It is a popular form of gambling in the United States and is run by state governments. In the United States, lottery games can take several forms, including instant-win scratch-off tickets and daily drawing games. The state governments that operate lotteries are also responsible for selecting and licensing retailers, training employees of these stores to use lottery terminals and selling tickets, and ensuring that the lottery games are promoted in a lawful manner. State laws vary as to how lottery proceeds are used. Some states use the money to fund education, while others use it for public services such as prisons and roads.

The word “lottery” is derived from the Dutch noun lot, meaning fate or fortune. Historically, people would put objects such as pebbles or pieces of paper with names or numbers on them into a receptacle (such as a hat) and shake it. The person whose name or number was drawn won the prize. Similarly, persons wishing to share a plot of land in a new settlement would draw lots to determine who got the best sites. The sense of a “chance allotment or share” is attested from 1570s; that of a “prize” is from 1630s, when the term was adopted by English from French.

In the modern sense, a lottery is a game in which people pay an entry fee for the chance to win a cash prize, usually determined by drawing lots. The prize amount can be a single large sum or a series of smaller prizes. In addition to money, some lotteries offer goods such as cars or vacations. The odds of winning vary greatly depending on the size of the jackpot and the number of tickets sold.

Some people try to increase their odds by using a variety of strategies, although these strategies rarely improve the odds by more than a small margin. Others play the lottery as a way to experience a thrill and indulge in a fantasy of becoming wealthy. Some of these people are willing to spend a substantial fraction of their incomes on tickets, and they often purchase multiple tickets each week. Typically, lottery players are lower-income, less educated, and nonwhite.

Lottery advertising focuses on the excitement of winning and the glamor of being rich. It obscures the regressivity of the lottery and encourages people to gamble more. Moreover, it reinforces the idea that gambling is inevitable and that governments should simply tack on a lottery to their budgets to capture this inevitable gambling. This view, however, misreads the real reason why states enact lotteries. They do so because they need the revenue. State legislatures may believe that if they tack on a lottery, they will attract the most enthusiastic gamblers and thus raise the most money. They are wrong. The truth is that the regressive effects of lottery gambling are even more severe than they realize.
