Lottery is a form of gambling in which numbers are drawn for a prize. Some governments outlaw it, while others endorse it to the extent of organizing a national or state lottery and regulating its operation. A number of different games are available, including the powerball, which has a single draw and an enormous jackpot. In addition, there are games with a more limited pool of numbers, such as the keno.

Choosing decisions or determining fates by lot has a long history, with examples in the Bible and in Roman and Greek culture. In modern times, however, lotteries have gained widespread popularity as a means of raising and distributing money. They offer the potential for instant wealth to a large segment of the population and can be attractive in times of economic stress, when tax increases or cuts in public services might erode public support.

Despite criticisms of lotteries, including the problem of compulsive gamblers and their alleged regressive impact on lower-income groups, the industry continues to thrive. Lotteries enjoy broad popular support, especially in states where they are seen as benefiting a specific public good such as education. In addition, the popularity of lotteries has spawned extensive and powerful constituencies that include convenience store owners (the primary retailers for the tickets); lottery suppliers (whose heavy contributions to state political campaigns are widely reported); teachers (in states where lottery revenues are earmarked for education); and even state legislators themselves, who can expect significant campaign contributions in return for their votes in favor of lotteries.
