Players' points are calculated based on Elo rating system, which is considered the most accurate system for ranking player ability. After each match, the winning player will take points from the opponent. The number of points that the winner takes is calculated based on the winner's current points, opponent's points and the importance of the match. If enough number of matches are played, the best players will be at the top of your ladder. Any match format can be used.
