The Elo rating system is a widely recognized method used to rank players in competitive gaming, drawing its origins from the world of chess.
It was developed by Arpad Elo, a Hungarian-American physics professor, in the 1960s.
Initially designed for the World Chess Federation (FIDE), the system was a revolutionary way to rank players based on their performance in games.
Today, it has been adopted across various competitive games, including popular video games such as League of Legends, PUBG, Valorant, and many others, to provide a fair and balanced ranking system for players.

How the Elo System Works?
At its core, the Elo system is a ranking system designed to measure the relative skill levels of players.
The way it works is simple: players gain Elo points for winning matches and lose points when they lose.
0. If a player beats someone with a higher Elo ranking, their Elo score increases significantly because the system views this as a stronger achievement.
Conversely, if they lose to a lower-ranked player, their Elo score will drop more substantially, as the result is considered an unexpected or poor performance.
Balanced Matchmaking with Elo

. By calculating Elo scores over a period of time, the system helps ensure that matches are more enjoyable for all participants, as players face opponents who are roughly as skilled as they are.
This also prevents unfair matchmaking, where low-ranked players might face highly skilled opponents and vice versa.
Continuous Ranking Adjustments
One of the key aspects of the Elo system is its ability to update a player’s rank continuously. Every match results in a change to the player’s Elo score based on the outcome.
A player’s Elo is adjusted after each game to reflect their performance and the strength of their opponent.
For instance, if a player with a lower Elo rating defeats an opponent with a significantly higher score, the lower-ranked player will gain more points than if they had defeated someone with a similar ranking.
On the other hand, if the player with the higher Elo loses, they will lose fewer points, since the outcome was expected based on the rating difference between them and their opponent.
Climbing the Rankings with Elo

Over time, this results in players being matched with those of comparable skill levels, enhancing the quality of gameplay for everyone involved.
As players advance, the Elo system ensures that it becomes increasingly difficult to climb the rankings.
This means that players need to consistently perform well to maintain and improve their Elo, which includes an element of challenge and excitement to competitive games.
Common Terms Associated with Elo
In addition to the Elo rating itself, there are a few terms commonly associated with the system.
For example, MMR (Matchmaking Rating) and SR (Skill Rating) are often used interchangeably with Elo, though they may be slightly different depending on the game.
Another term, Elo Hell, refers to a situation where players feel stuck in a particular Elo range despite improving their skills.
This can be frustrating for players who believe they are better than their current rank suggests.
Similarly, smurfing refers to experienced players creating new accounts to face less-experienced opponents, which can skew the Elo system.
Conclusion: The Importance of Elo in Competitive Gaming
In conclusion, the Elo system is an essential tool in competitive gaming, designed to create balanced and fair gameplay experiences.
It is a dynamic ranking system that rewards skillful play and ensures that players face opponents of comparable ability.
Whether you’re a beginner or an experienced player, understanding how Elo works can help you improve your performance and navigate the competitive landscape of your favorite games.
