I have played a couple of matches, and when i win (Just a single round, not the entire match) it doesn't says how many games are left to move on to the next ranking, and either when i won the entire match, is there a way to know how many games are left, or is this a glitch or something?
The Elo[a] rating system is a method for calculating the relative skill levels of players in zero-sum games such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor.
