The lottery is a game of chance in which numbers are drawn to win a prize. The prizes may be cash or goods. Alternatively, the prize may be a percentage of total receipts. The first lotteries were held in the Low Countries during the 15th century to raise funds for town fortifications and the poor. Some of these early lotteries had a fixed amount as the prize, but more commonly, the prize money is a percentage of ticket sales.
