Tennis Ladder League Guide

Ladder leagues rank players in order. Beat someone above you to move up. Lose, and you may drop — keeping every match meaningful.

Elo estimates skill based on who you play and whether you win. Beating a stronger opponent moves your rating more than beating a weaker one.

Courtlio supports formats clubs actually run — from round-robin group stages to knockout brackets and hybrid ladder playoffs.
