Lottery is a gambling game in which numbers are drawn and prizes awarded. It is a form of public entertainment that is popular in many countries. In the United States, state-sponsored lottery games are common. These are generally organized by state governments and offer a wide variety of prizes, such as cash, goods, services and even real estate.

The game of lot is a common feature of sports and other events, including governmental procedures: the state used a lottery to assign spaces in the campground.
