A lottery is a game in which paying participants have the chance to win prizes, usually money, by matching numbers. In modern lotteries, participants buy a ticket and either select a group of numbers or have machines randomly spit out ones for them to choose from. The odds of winning are determined by comparing the numbers that each participant has chosen against the total number of possible combinations. Normally, some percentage of the prize pool is set aside for costs and profits, and the rest is available to winners.
The lottery was common in early America, where it helped finance many colonial buildings (including the first church buildings) and a few other public institutions. But it also became tangled up in the slave trade, sometimes in unexpected ways. George Washington once managed a lottery whose prizes included human beings, and one enslaved person, Denmark Vesey, purchased his freedom in a South Carolina lottery and went on to foment a slave rebellion.
When states introduced lotteries after the American Revolution, they were searching for budget solutions that wouldn’t enrage an anti-tax electorate. Most followed remarkably similar patterns: they legislated a monopoly; created a state agency or corporation to run the lottery; started with a small number of fairly simple games; and then, under pressure to generate additional revenues, progressively added more complex games.
