Lottery is a form of gambling in which prizes are allocated by a process that relies wholly on chance. Prizes can be awarded for a wide variety of things, including money, vehicles, real estate and vacations. The concept of lottery has a long history, including ancient times when the casting of lots was used to determine fates or for other purposes. Since the early modern period, the lottery has become a popular means for governments to raise funds for a variety of purposes.

State lotteries enjoy broad public support, and their popularity is especially high during periods of financial stress, when states are considering tax increases or cuts in public services. The public perception that the lottery promotes a particular public good, such as education, is one of the primary reasons why lotteries are so popular in some states.

Many people play the lottery on a regular basis, and often purchase tickets at convenience stores or other outlets that sell them. Some players use a particular system for selecting their numbers, such as choosing the dates of important events, or avoiding the selection of numbers that are too close together (which could reduce their chances of winning by having to split the jackpot). Others, particularly more serious players, play the lottery with the intention of making a profit.

Although the profits from the lottery may help to fund a number of public projects, critics argue that lotteries can also have negative consequences. They can lead to compulsive gambling, and they have been shown to have a disproportionately detrimental impact on lower-income people.
