Swiss Tournaments
An often overlooked major feature on Challonge.com is the Swiss tournament
format. While running a Swiss tournament on paper is a nightmare, we've
taken the pain out of it to bring its many advantages over traditional
brackets to light.
Swiss tournaments give equal play time to participants, pair players with
others of similar skill level, and determine a winner in far fewer rounds
than you'd anticipate. They're essentially smarter, abbreviated round robins.
First Round
Top seeds are paired against bottom seeds. Random seeding should be used if
no ranks exist. For 8 players, the pairs would be 1v5, 2v6, 3v7, and 4v8.
Points
Match wins are awarded 1 point, ties 1/2 a point, and byes 1 point (or as
configured). For multi-set/game matches, you may opt to award points for set
/game wins as well - this gives match losers a chance at partial credit.
Additional Rounds
After each round, players are grouped by score. The top and bottom half of
each group is then paired (same method as the first round), but steps are
taken to ensure there are no rematches. Players float up or down between
groups if necessary. When there's an odd number of players, a bye is awarded
to the lowest ranked player who has not yet received one.
The minimum number of rounds to determine a winner is equal to the binary
logarithm of the number of players rounded up (3 rounds for 8 players, 4 for
16, 5 for 32, and so on). On Challonge, you can opt to play more rounds
than the minimum for more definitive results.
Final Results
Players are ranked by score at the conclusion of the tournament, with ties
broken using the Median-Buchholz system. | D***e
