Answers to Questions
How to generate the rounds list for a championship?
Enter the list of participants (teams, players, people, competitors etc.) in the table, one per cell. Then click the button to start a random round-robin tournament generation.
Each item will contain all the others. All games that can be performed simultaneously (in parallel) will be grouped.
Example: With 4 teams Team1,Team2,Team3,Team4, a possible draw is :
Round 1 : Team1 vs Team2 and Team3 vs Team4
Round 2 : Team1 vs Team4 and Team2 vs Team3
Round 3 : Team1 vs Team3 and Team4 vs Team2
If the number of participants N is even, then there will be N-1 championship days in the calendar.
If the number of participants is odd, every round a participant has no opponent.
How to generate the rounds list for two legged ties?
Some championships, for fairness, organize round-trip matches, with a home game and an away game. The generator can take into account these specificities in order to list games respecting 50% of home and 50% of away and / or to include two-legged tie.
What is the difference between a championship and a tournament?
A championship is composed of a single pool.
A tournament is composed of a tree.
