Making a tournament schedule comes down to four decisions: how many teams, which format, how many pitches and how long a match lasts. Once those four are settled, the rest follows.
The format determines how many matches are played and whether everyone stays equally long.
In a group where everyone plays everyone once, the number of matches is n × (n − 1) ÷ 2, where n is the number of teams in that group. Four teams therefore give 6 matches, five teams 10.
Split 12 teams over 3 groups of 4 and that is 3 × 6 = 18 group matches. Put them in one group of 12 and it becomes 66. More groups means fewer matches — and so a shorter tournament.
Add the change-over time to the match length, divide the total number of matches by the number of pitches, then multiply:
duration ≈ (number of matches ÷ number of pitches) × (match length + change-over)
18 group matches on 3 pitches, 12 minutes of play and 3 minutes change-over: (18 ÷ 3) × 15 = 90 minutes. Add a final stage of 4 matches and count on another 20 to 30 minutes.
In UwTornooi you enter teams, pitches, match length and start time, then click Generate. The schedule takes the change-over time, break windows and a team's minimum rest between two matches into account. Afterwards you can still drag cards around the schedule — every move is saved immediately.
Four or five works best in practice. With four, each team plays 3 matches; with five, 4 matches. Larger groups add up quickly: a group of 8 is already 28 matches, which makes the wait between your own matches long.
Yes, and it is one click: adjust the teams and generate again. If you only want to reshuffle one group, you can choose at generation time which category or group to recalculate, so the rest stays put.
Yes. After generating, drag the match cards to another time or pitch. Conflicts — two matches at once on one pitch, or a team with too little rest — are flagged in colour straight away.
