Darts is a form of throwing game in which darts are thrown at a circular target (dartboard) fixed to a wall. Though various boards and rules have been used in the past, the term "darts" usually now refers to a standardised game involving a specific board design and set of rules. As well as being a professional competitive sport, darts is a traditional pub game, commonly played in the United Kingdom, across the Commonwealth, the Netherlands, Belgium, Republic of Ireland, the Scandinavian countries, the United States, Canada and elsewhere.
