Doubles curling (most commonly seen as mixed doubles) is a variation of the sport of curling with only two players on each team. Mixed doubles is the most common format of doubles curling, where the term 'mixed' specifies that each team is composed of one man and one woman. The term mixed is also used to describe a specific format of 4-person team curling where the team consists of two men and two women and the throwing order alternates genders, see mixed team.
With its smaller teams and quicker games, doubles curling has provided an opportunity for more countries to participate in international competition. At the 2019 World Mixed Doubles Championship 48 of the 61 World Curling Federation member countries were represented, including the first international curling competition for Kosovo, Ukraine, Nigeria, Saudi Arabia, and Mexico.[1]
