Dart is an arc-shaped throwing device, which originated in Australia and was originally used by Australian aborigines to hunt or attack enemies. There are two kinds of darts. One is non-darts, which can only fly in a straight line. It is usually rod-shaped with a pickaxe at one end. The other is boomerang, which is developed from boomerang that does not fly back. It swerved suddenly in flight, light and thin, and made of hard bent wood. Anti-darts are generally about 30 ~ 75 cm long and weigh about 340 grams. Their shapes are V-shaped, cross-shaped and propeller-shaped. V-shape is the most common.

As a sport, boomerang throwing is quite popular in Australia, America, France and other countries. Football fields, polo fields or empty suburbs can all be used as places to throw darts. When throwing, hold a leaf of the dart and throw it forward with wrist force so that the rotating plane of the dart forms a certain angle with the horizontal plane. 1983 the first world darts championship was held in Australia. The United States also hosts the Hollywood International Dart Silver Cup every June. In this sport, Australian athletes have a high level and have advantages in accuracy and speed. However, American athletes prefer to throw figures, which leads to the difficulty of sports skills and performance. The competition is divided into several forms: one is to compare the number of darts thrown and recovered in a certain period of time; The other is the flying distance of darts; Another is the flight time of darts.
