Lottery: A game in which numbered tickets are sold and prizes are awarded to holders of numbers selected at random; especially a competition as a means of raising funds for a public purpose. Also, (in more general use) any process of allocation that relies on chance.

In the United States all state-sponsored lotteries are considered monopolies, and their profits are used exclusively for government purposes. Private lottery companies may not compete with state lotteries, and they must be licensed by the state to sell tickets. Lotteries are popular among some people because they offer the opportunity to win large sums of money. But they can also be costly to people with low incomes. Studies show that those with the lowest incomes spend a disproportionate amount of their money playing for lottery jackpots, and critics call these games a disguised tax on society’s poorest citizens.

The word “lottery” derives from the Dutch phrase “lot,” meaning fate or fortune, and a chance game in which numbered tickets are drawn at random to determine winners. In its early days, the lottery was an important tool for financing public projects in colonial America. George Washington ran a lottery in the 1760s to finance construction of the Mountain Road in Virginia, and Benjamin Franklin supported lotteries to pay for cannons for the Revolutionary War.

Today’s lotteries take many forms. Some are run by states, and others by nongovernmental organizations. In the United States, state-sponsored lotteries are administered by a governmental agency, and oversight and enforcement of lottery rules is usually performed by the attorney general’s office or state police.
