Lottery is a form of gambling in which prizes are allocated by chance. It is a commonplace practice, and in most cases the chances of winning are not very high. However, some people are very enthusiastic about lottery playing, and there is a real sense of hope that one day they will win the big prize. This is a kind of wishful thinking, but it is understandable in the context of an environment of inequality and limited social mobility.

The casting of lots to decide fates and property rights has a long history, including several instances in the Bible. The first recorded public lotteries to offer tickets with prize money occurred in the Low Countries in the 15th century, raising funds for town fortifications and helping the poor. Lotteries also played a prominent role in the early colonial history of America, financing roads, churches, libraries, colleges, canals and wharves. Benjamin Franklin even sponsored a lottery to raise money for cannons to defend Philadelphia against the British.

Despite these benefits, there are serious problems with state-sponsored lotteries, including the way they promote gambling. Running a lottery as a business with a focus on maximizing revenue necessarily involves aggressive marketing and promotion, which can lead to negative consequences for the poor and problem gamblers. It can also cause state officials to neglect other public responsibilities, such as providing services to the mentally ill and drug addiction recovery. This has led to the proliferation of new types of games, such as keno and video poker, and an increase in advertising expenditures.
