A lottery is a game in which players pay a small sum of money for a chance to win a larger amount of money or goods. Some examples include a lottery for units in a subsidized housing block or kindergarten placements. Financial lotteries are the most common and are usually conducted by governments or private organizations. The drawing of lots to decide ownership or other rights is recorded in ancient documents, including the Old Testament and Roman emperors’ distribution of property and slaves. In the modern era, people play lotteries to earn money for schooling, health care, and public works projects.
