A lottery is a game in which people buy tickets to win prizes. The winning numbers are chosen by a random procedure and the prize money is distributed to the winners.

Lotteries have become a common method for fundraising in many countries, and they are often run as a business. The government aims to maximize revenues, and the lottery must be promoted to attract target groups. However, there are concerns about the impact on the poor and problem gamblers.

Most lotteries are based on the principle of chance, which is designed to ensure that only a small number of people will win.
