The lottery is a game of chance in which tokens are distributed or sold, and a prize (often money) is awarded to those who match numbers. The word is believed to be derived from Middle Dutch loterij “action of drawing lots” or from Middle French loterie, and it was first used in English in 1569. Today the term is used for many types of events involving prizes based on random selection, including commercial promotions in which goods or services are given away, military conscription, and some forms of government-sanctioned gambling. It is also the name for a group of people who are selected by chance to serve on a jury or to participate in other activities that depend on fate, such as combat duty.

In the United States, state lotteries have long been popular and are considered a good source of painless revenue for public purposes. However, critics point out that the exploitation of vulnerable groups is a serious problem. Some of the most notable critics include convenience store operators, lottery suppliers (whose contributions to state political campaigns are often reported), teachers (in those states where a portion of proceeds is earmarked for education), and politicians.

A number of strategies are used by lottery players, such as avoiding numbers that start or end with the same digit and using family birthdays (one woman who won a large jackpot was said to have picked seven for her lucky numbers). However, there is no guarantee that any strategy will work; it all depends on luck. The best advice is to play a little bit of every draw, and always check the expected value of your ticket.
