Dartball is a game in which darts are thrown at a large wooden or homasote board that resembles a baseball field with colored areas which denote bases. Dartball uses baseball-like rules and scoring. Dartball rules and board configurations vary from league to league, but generally teams comprise either seven or nine players plus possible alternates. Dartball teams are usually formed by churches, often playing their games during fall and winter months in church basements or common areas. Most leagues end their seasons with championship tournaments held at local high school gymnasiums.
