Multi-day sports competitions usually consist of a ‘single round robin’, with one team playing on its home field in each round of matches.
Using mytournament.info, you can easily realise such a tournament. . . . . .

Often, a tournament with final rounds has no resit options: a defeat results irrevocably in elimination of the losing team.
In contrast, a double-elimination tournament is one where a competitor is excluded from the final only after losing two games.. . . . . .

A single-elimination tournament (also called a knockout tournament) is a tournament format in which a team or player is immediately eliminated in case of a loss.
When you win, you advance to the next round. If you lose, you are out of the tournament.. . . . . .
