how many rounds in swiss tournament

In a Swiss tournament, the number of rounds is typically determined by the number of participants. The general rule is:

* For a small number of participants (up to 10-12 players), a single round-robin format can be used, where each player plays every other player once.
* For a larger number of participants (13 or more players), a Swiss system tournament is used, where the number of rounds is typically between 6 to 13 rounds.

A general guideline for the number of rounds in a Swiss tournament is:

* 6-8 rounds for 13-32 players
* 8-10 rounds for 33-64 players
* 10-12 rounds for 65-128 players
* 12-13 rounds for 129 or more players

However, the exact number of rounds may vary depending on the specific tournament and the preference of the tournament organizers.

It’s worth noting that the number of rounds should be chosen to ensure that the tournament is fair and that the winner is determined by their performance, rather than by random chance. In general, the more rounds, the more accurate the tournament results will be.
