The dartboard is divided into 20 segments, the 20 as the highest value is always at the top in the middle. The outer double ring limits the scoring range. All hits outside the double ring do not score any points. A hit in the double segment doubles the value of the respective segment. The double-20 is therefore worth 40 points. Hits in the triple range result in three times the value. Three throws into the triple-20 are with 180 the highest achievable value. The Bulls eye scores 50 points, a hit in the single bull scores 25 points.
The dimensions are always uniform. The dartboard is fixed to the wall so that the Bulls-Eye is at a height of 1,73m. The distance from the front of the dartboard to the oche is 2,37m.
501 points are the initial value of one leg. The objective is to reduce the score from 501 to 0 as quickly as possible. Players take turns throwing three darts. The score obtained is subtracted from the remaining score. The player who can play his score on 0 first wins the leg.
A leg can only be finished with a throw into a double field. Double fields include the 20 narrow outer rings and the Bulls Eye (double-25). Some tournaments (currently only the World Grand Prix in Dublin) also play in “Double-In” mode, where a Leg must be opened with a hit in a double field.
PDC tournaments are played in either “Set Mode” or “Matchplay Mode”. In “Set Mode” a certain number of Legs must be won in order to win a Set. Example: If the mode is “Best of 5 Sets, Best of 5 Legs”, the player who first wins three Legs wins the Set. The player who first wins three sets is the winner of the game.
In “Matchplay Mode”, a certain number of Legs is specified. In “Best of 21 Legs”, the player who wins 11 Legs first wins the match. On the PDC Pro Tour and at the PDC Europe events, the game is always played over the distance of “Best of 11 Legs”. In the Semi-finals the distance increases to “Best of 13 Legs”, the Final is played over the distance of “Best of 15 Legs”.
Further basic rules
Each player has three darts available for a throw. The darts must be thrown individually. Any darts that fall off the board or bounce off will not be counted. The darts must remain stuck until the player has pulled the darts off the board himself. If a dart falls off the board beforehand, it does not count. Then it is also irrelevant whether the caller or writer has already passed this value. The score must then be changed accordingly. It is therefore no rudeness of the players if they first pull the darts off the board before the handshake with the opponent. When throwing, the player must stand behind the oche. If the player is far outside, the stand must be based on an imaginary extension of the oche. No throwing circle is formed. One foot must always touch the ground. In stage games there is a colored throwing area. While a player is throwing, his opponent may not enter this area.
