A nine-dart finish, also known as a nine-darter, is a perfect leg or single game in the sport of darts. The object of the game is to score a set number of points, most commonly 501; in order to win, a player must reach the target total exactly and hit a double scoring area with their last dart. When the target is 501, the minimum number of darts needed to reach it is nine. For example, one way to achieve a nine-dart finish is to score 60 on each of the first seven throws, then a 57 on the eighth, and lastly a 24 on the ninth. It is regarded as an extremely difficult feat to achieve even for the sport's top players, and is considered the highest single-game achievement in the sport, similar to a maximum 147 break in snooker or a 300-point game in bowling.
