Lottery is a game in which players pay for tickets and hope to win prizes by selecting numbers. Depending on the type of lottery and its rules, the odds of winning vary widely. Lotteries are considered state-sponsored gambling and are designed to generate revenue for the government. Some states use lottery proceeds to fund public services, such as housing units for the poor or kindergarten placements. Others, such as Oregon, have a policy of allocating lottery proceeds to education and public health programs. Regardless of the intended purpose, lottery advertising often focuses on the idea that buying a ticket is a civic duty to help the state.

The earliest evidence of a lottery comes from the Chinese Han Dynasty between 205 and 187 BC, when people would draw keno slips in order to determine the order of selection for government posts. In the modern era, lotteries are an integral part of state governments. They raise millions of dollars each year, generating organic news coverage and attracting new participants. But is it appropriate for a government to profit from a form of gambling?

Lotteries have become an essential tool for state governments to manage their finances in an anti-tax era, and they have gained broad public approval. However, they may be at cross-purposes with the broader public interest, as they promote a form of gambling that can lead to addiction and other social problems. In addition, the evolution of a lottery is a classic example of public policy made piecemeal and incrementally, with little general oversight or control.
