The Swiss system

The Swiss system has proven itself to allow all participants the same number of games in the tournament. It is also a fair system in which the opponents are calculated based on their playing strength.

a) In the Swiss system, all participants always play the same number of times because each participant remains in the tournament even if they lose and still has a chance of a good final placement in the next rounds of the game

b) Participants with different skill levels can take part in the tournament; From the third round of the game at the latest, participants who are roughly equal in strength and those who are one behind the other in the rankings play against each other

c) All participants have a performance-based and individually determined tournament course, especially since they cannot meet the same opponent twice due to the system controls

Ideal conditions for a darts tournament played in Swiss tournament mode

In order for there to always be a clear winner in a round-robin tournament, all participants must have played - if possible at the same time - so many rounds that at the end only one participant is still undefeated or the participant with the most wins or the best rating is has enforced.

The minimum number of rounds 'n' required for an optimally played tournament in the Swiss game mode results from the number of players participating. As soon as the number of participating players is smaller than the result calculated using the formula '2 to the power of n', the parameter 'n' corresponds to the number of rounds required.

A daily tournament with 3 to 7 game rounds could then ideally be carried out as follows:

2 to the power of 3 = 2*2*2 = 8 participants (means: with 8 participants, 3 game rounds should be created)
2 to the power of 4 = 2*2*2*2 = 16 participants (means: with 16 participants, 4 game rounds should be created)
2 to the power of 5 = 2*2*2*2*2 = 32 participants (means: with 16 participants, 5 game rounds should be created)
2 to the power of 6 = 2*2*2*2*2*2 = 64 participants (etc…)
2 to the power of 7 = 2*2*2*2*2*2*2 = 128 participants

(Fewer rounds can also be created in the 2K Dart software - for example 3 rounds with 16 participants, although an ambiguous table situation may arise due to the rounds played below the optimum).

Conclusion:

The more participants you have in the tournament, the more rounds can be played. The fewer participants you have, the fewer rounds can be played, because at some point you will reach the point where there are no longer any opponents available due to the BHW/FBHW. (A detailed explanation of the BHW/FBHW and the generation of the new fixtures based on the table situation can be found in a separate article).
The maximum number of possible game rounds in the 2K Dart software corresponds to half the number of participants.

A new round can only be created once the previous round has been completed, with the bottom of the table playing against each other first in each round.
