League Maker App isn't a template with a fixed format: it's a sports competition engine built from chainable phases — league, single or double elimination, Swiss system, McMahon system — each with its own pairing, points and configurable tiebreaks. This documentation describes every option available today in technical detail: to help you decide whether it fits what you need, or to explain it to whoever asks.
How this is organized
The menu on the left groups the features into six blocks:
- Concepts — the predefined formats, the chainable phases system and the points/tiebreak configuration shared by every sport.
- Chess and Go — the rule set specific to these two games: McMahon, seeding, bye, optimal pairing and balanced color.
- Integrations — export and import with federations, venues and white-labeling.
- Matches — automatic schedule, result confirmation, match reports, set scoreboard with rating, withdrawals, automatic scheduling and statistics.
- Organization — teams, players, referees, seasons and role-based access control.
- Distribution — embeddable widget, push/PWA notifications, comments and match reports.
And, separately, frequently asked questions.
The core idea: phases, not formats
A competition doesn't have a single format frozen at creation time. It's a sequence of phases, each resolved by a pure pairing engine (round-robin, knockout, Swiss, double elimination or McMahon), chained together through an advancement rule that decides who moves from one phase to the next. That's why "league + playoffs" isn't a separate format, but two phases connected together: a regular league followed by a knockout bracket among the top finishers. See Chainable phases.
