Nine-dart finish (a perfect leg)

In darts, a nine-dart finish is a perfect leg.
The player only uses nine darts, the fewest possible, to checkout from 501.

This is notoriously difficult to achieve, even by the game's top professionals.

In a single game (also known as a leg) of darts the players requires to score 501 points and end with either the Bullseye or a double.
Every thrown consists of exactly 3 darts and 60 is the maximum that can be scored with a single dart. The maximum is thus 180 and nine throws are the minimum necessary to win.

Many combinations are possible but the traditional nine-dart finish requires a score of 60 (treble 20) with each of the first six throws, that is, with the first two shots of three. This leaves 141 to score on the final shot (of three darts), also known as the outshot.

This outshot is traditionally performed in one of three ways:

  •     treble 20 (60), treble 19 (57) and double 12 (24)
  •     treble 20 (60), treble 15 (45) and double 18 (36)
  •     treble 17 (51), treble 18 (54) and double 18 (36)

John Lowe performed the first televised nine dart finish at the MFI World Matchplay on 13 October 1984. He used T17, T18 and D18 as is outshot.
For this he received a prize of £102,000, and he went on to win the whole event.
