A lottery is a system where people have a chance to win a prize. They may be used to fund charity, raise money for a cause or fill vacancies on sports teams, among others. A lottery may also be a way to make a decision when there is a lot of demand for something that can be scarce, such as a vacancy on a housing block or a place in a school.
In a lottery, the odds of winning a prize are based on how many people play. The chances of a person winning the prize are higher if more people play, which is why it is important to play as much as possible.

During the 15th century, some towns in the Low Countries held lotteries to raise money for town fortifications or for poor people. They were also seen as a form of voluntary taxation that could be raised by the population.
