Generally, a set will consist of the best of five legs (first player to win three) – although there are some exceptions.
During the final of the 2007 PDC World Darts Championship, Raymond van Barneveld defeated Phil Taylor by seven sets to six in one of the most dramatic darts matches of all-time.
Neither player managed to gain a two-leg advantage in the final set "tiebreak" so the deciding leg was played when the score reached 5–5.
Before the final leg, the players threw for the bullseye with the nearest given the advantage of throwing first.
In recent years, more and more new tournaments have decided against using sets as the scoring method – preferring to use the matchplay format of best of x legs (such as in the UK Open and Grand Slam of Darts).
