A tournament is a competition involving a given set of participants. These participants play against each other following a predefined structure. They are progressively eliminated until a winner is declared and a final standing is established.

The tournament has a number of properties that describe how the competition will take place. Some of these properties enable particular features (such as registration, check-in, ...). Others are simply used to provide information to the participants.


A tournament can only be played on a single discipline in order to ensure that the competition's performances are comparable. The discipline may also add settings and specific discipline-related features.

The discipline information is also supplemented with the platform (device) used in the tournament. When the discipline involves several platforms, it is possible for the tournament to restrict the platform(s) on which it will take place. The platform is however only provided for information purposes.
