The Swiss Tournament Format
In a Swiss tournament, teams are paired with another team with the same record after each round of matches. For the first round of matches teams will be paired based on their seeding, with top ranked teams matched with bottom ranked teams.
After the first round of matches in a Swiss tournament half of the teams will have a 1-0 record and half will have a 0-1 record. Each 1-0 team plays another 1-0 team, and each 0-1 team plays another 0-1 team, with pairings randomly drawn between teams with the same record.
After the second round, teams will have a record of either 2-0, 1-1 or 0-2, and pairings will be drawn again. Where there is an odd number of teams with the same record, a random team with that record will be drawn against a random team with the next closest record. Any rematches from previous rounds will be re-drawn.
Example: After the second round there are three teams with a 2-0 record, six with 1-1 and three with 0-2. A random 2-0 will be drawn to play against a random 1-1, and a random 0-2 will be drawn to play against a random 1-1. The remaining pairs of 2-0s and 0-2s will play against each other, and the remaining four 1-1s will be randomly paired.
Swiss at the 2019 European Qualifier Tournament and British Quidditch Cup
European Qualifiers and BQC will both use a three-round Swiss format on Day 1. After Day 1 games are completed, teams will be ranked and these rankings used to seed the bracket(s).
European Qualifiers 2019 will use a single flight of 12 teams, with teams paired for the first round based on regionals placing. Each regional champion will be randomly paired with one of the two bottom-ranked teams (6th and 7th placed at Southern). The runners-up will be randomly paired with one of the next two lowest ranked teams (5th placed at each regional), and so on until all teams are matched.
British Quidditch Cup
BQC 2019 will split teams into two flights of 16, with teams split alternately into flights based on their national ranking (as per the USQ ranking algorithm) – i.e. 1st – A, 2nd – B, 3rd – A, 4th – B, etc. Within each flight teams will be matched in sets of two, with the 1st and 2nd ranked teams paired randomly with the 15th and 16th, the 3rd and 4th paired randomly with the 13th and 14th, and so on.
All teams on a 3-0 or 2-1 record will advance to the upper bracket and all teams on a 1-2 or 0-2 record will go into to the lower bracket.
