The lottery is a form of gambling in which participants pay a small sum of money for the chance to win a larger amount. Unlike most forms of gambling, the lottery is not considered a sinful activity. In fact, lotteries have long been used to do good things, from distributing property in the Old Testament and Roman emperors’ gifting of slaves to giving out subsidized housing units and kindergarten placements in a reputable public school.

The most well-known type of lottery is a state-run game that awards cash prizes to paying participants who match numbers randomly selected by machines. While these games were once controversial, they have now become so common that nearly every state has one. The success of the state lottery has spawned numerous other commercial types of gambling, including commercial promotions in which property is given away and, of course, professional sports teams’ drafts of players.

Until recently, however, most state lotteries were little more than traditional raffles. People paid a few dollars to buy a ticket, and the winner was determined at some point in the future, usually weeks or months out. To maintain and even increase revenues, the lottery industry introduced innovations such as scratch-off tickets and games with increasingly astronomical prize amounts.

The wealthy do play the lottery, but they tend to purchase fewer tickets than the poor; their purchases represent a smaller percentage of their incomes. Moreover, they can afford to wait longer for their chances to win. As a result, the lottery has become what Cohen calls a “budgetary miracle:” a way for politicians to raise revenue without risking a backlash at the polls.
