What is a Lottery?

Lottery is a competition in which numbered tickets are sold and prizes are awarded to the holders of numbers drawn at random; it is typically organized by states or sponsors. Its organizers must set rules defining the frequency and size of prizes, as well as the costs of organizing and promoting the lottery. Of the money collected from ticket sales, a percentage goes as revenues and profits to the state or sponsor, while the remainder is available for the winners. Prizes are normally sized to attract large numbers of players and maximize revenue. In addition to the main drawing, some lotteries have rollover drawings in which winning tickets are re-sold for a higher prize.

The lottery has long been a popular way to raise funds for public projects, particularly in colonial America. Lotteries were used to finance roads, canals, bridges, schools and churches, and even the founding of Princeton and Columbia universities was financed by them. They were also used to fund the expedition against Canada, and Benjamin Franklin held a lottery in 1776 to raise funds for cannons to defend Philadelphia against the British.

State lotteries are run as businesses with a focus on maximizing revenues, so their advertising necessarily emphasizes persuading target groups to spend money on them. Some states also promote the idea that the money they receive from these enterprises is earmarked for certain public purposes, and this message seems to be especially effective in times of economic stress. Nevertheless, studies show that the popularity of lotteries is not connected to the overall fiscal health of state government.
