Swiss system tournaments

How does Swiss system work?

In Swiss system tournaments (also known as Swiss tournaments), every team plays a fixed number of rounds. For every match won or lost, teams ranking changes on a leaderboard.


How are teams matched each round?

In round 1, teams are matched using the team’s FACEIT skill level (average player skill level). Matching is done using the fold method, matches the highest FACEIT skill level team against the lowest (e.g. lvl 10 vs lvl 1), then matching the next highest and lowest ranked teams, until all teams are matched.If teams have the same skill level, a random team with the skill level is matched. Organizers may manually edit the first round team seedings.


In round 2 (and all further rounds) teams are matched with the same (or most similar) win-loss ratio, until all rounds are played. Example: You win your first match (winn ratio: 1-0). You are matched against someone else who also won their first match (win ratio: 1-0).


Every round the matching continues until all rounds of the tournament have been played.


I think a matchup is wrong. Why did team X get matched against team Y?

Depending on the number of teams playing, you may be given a BYE (also known as a walkover) or play a team with a higher or lower win-loss record. No team ever receives more than one BYE. You never play against any team more than once. 


Can I still win a Swiss after I lost a match?

A team may still win a Swiss tournament after losing matches, if the number of rounds is larger than the minimum number of rounds required to determine a winner. Check the tournament rules to find out if you can win a prize after losing a match.


Do teams play all rounds in a Swiss?

Yes, teams don’t get eliminated after losing a match. An exception is the Swiss bracket, where the organizer qualifies and disqualifies teams in later rounds.

Is the next round generated right after my current match ends?

No. Since match results impact the next round’s team matching, all matches of the previous round need to be finished and any admin calls need to be solved.Round generation has to be triggered manually by a tournament admin from the matches page.


How many rounds are there in Swiss?

This depends on what the tournament organizer sets. Usually a clear winner needs to be determined for the main prize. When setting up a Swiss tournament, this number is calculated and displayed on the rounds drop down.


What if a multiple teams finish with the same score?

If this happens, tiebreakers are used to create a more granular ranking. A tiebreaker is a rule used to determine the ranking among teams that have the same point score at the end of the tournament.


Which tiebreakers are used for the tournament I’m playing?

Organizers may use custom tiebreakers for their tournaments. Please check the tournament rules to find out which tiebreakers are used.


What are the default Swiss tiebreakers on FACEIT?

Swiss tournaments on FACEIT use the Buchholz score as primary tie breaker. The default secondary tiebreaker requires tied teams to play a tiebreaker match between each other.

When is Swiss system the best format?

Swiss is also known as expedite Round-robin, allowing to determine a winner out of a large pool of participants without the need for everyone to play every single team in the tournament. Unlike single elimination brackets, Swiss tournaments are mostly run non-eliminatory, allowing teams to still win or keep playing for a high ranking and a prize after losing a match. 


What are the challenges running Swiss system tournaments?

Swiss system tournaments are operationally challenging and often rejected by content creators due to the effort involved. The FACEIT tournament system matches teams and generates rounds on a Swiss system algorithm through the click of a button.
