# ELO Ranking
Elo ranking is a player skill evaluation system widely used in games. It determines the level of competence and experience of players in competitive gaming. Each player has their own Elo ranking, which changes based on the outcomes of their matches.
The fundamental principles of Elo ranking include:
* Players start with a designated initial ranking.
* The outcome of a match affects players' ranking adjustments.
* Players with a higher ranking lose more points for losses and gain fewer points for wins when competing against lower-ranked players.
* Players with a lower ranking gain more points for wins and lose fewer points for losses when competing against higher-ranked players.
The Elo system creates fair and balanced matches, enabling players to compete against individuals with similar skill levels. It is a tool that contributes to satisfying and competitive gaming experiences.
In RoboHero, the Elo ranking aims to precisely match opponents for PvP battles, ensuring that player levels are as accurately matched as possible. On its basis, we also create the RoboHero divisions.
