Lottery is a game in which players pay for tickets and receive prizes if their numbers match those randomly chosen by machines. The drawing of lots to decide ownership or other rights has a long record in human history, including many instances in the Bible. But the use of a lottery to distribute material rewards is much more recent. The first known public lotteries to award cash prizes were held in the Low Countries in the 15th century. Town records in Ghent, Bruges, and other cities show that the distribution of money was an important feature of these early lotteries.

In modern times, state lotteries have become a widespread phenomenon. The lottery is a popular source of revenue for state governments, and many people play regularly. However, the success of a lottery depends on several factors, most notably its ability to attract customers and manage its costs. In addition, the popularity of a lottery may be affected by its perceived benefits to society.

A key argument used in states seeking to adopt a lottery is its value as an alternative to raising taxes or cutting public programs. But this benefit is not always clear, and studies suggest that the objective fiscal condition of a state does not seem to influence whether or when it adopts a lottery.

In general, lottery sales rise sharply following their introduction, then level off and sometimes even decline. To counter this trend, lottery officials introduce new games to maintain or increase revenues. Among these innovations are instant games, which allow players to buy tickets immediately. These games typically offer lower prize amounts and higher odds of winning than the traditional lotteries, which involve purchasing tickets to enter a draw in the future.
