Brief Overview of What Elo Is and Why It Is Important in Gaming
Elo is a rating system used to calculate the relative skill levels of players in various competitive games. It was originally developed for chess, but it is now used in a wide range of games, including League of Legends, Overwatch, and even board games.
The Elo rating system allows players to compete at a similar skill level, making the games more challenging and exciting. It also provides a clear way to track progress and improvement, both for individuals and teams.
What Is Elo?
Definition of Elo
Elo is a rating system that assigns a numerical score to a player or team based on their performance in a series of matches. The higher the score, the better the player or team is considered.
Explanation of How Elo Works
The Elo system works by comparing the expected win probability of a player or team with the actual win or loss outcome. The expected win probability is calculated based on the current Elo scores of the players or teams involved. If a player or team wins a match, their Elo score increases, and if they lose, it decreases.
The History of Elo in Gaming
The Elo system was invented by Arpad Elo, a Hungarian-born American physics professor and chess player, in the 1960s. It was first used in chess tournaments and quickly gained popularity because of its accuracy and simplicity. Today, it is used in many board games and video games to determine skill levels.
Applications of Elo in Gaming
Competitive Gaming
Tournaments
Elo ratings are used to seed players in many tournaments. The higher the Elo score, the better the player is considered, and they will be seeded accordingly. This ensures that the best players are matched against each other in the early rounds, leading to more exciting and competitive matches.
Leagues
Elo ratings are also used to determine league placements and promotions. Players or teams with higher Elo scores will be placed in higher-level leagues, and they will be more likely to be promoted to the next tier.
Matchmaking Systems
Online Multiplayer Games
Elo ratings are used in online multiplayer games to match players of similar skill levels. This ensures that the matches are fair and balanced and provides a more enjoyable experience for all players.
Ranking Systems
Elo ratings are also used in ranking systems to provide a clear measure of a player’s skill level. These rankings can be used to track progress, set goals, and compare performances with other players.
Elo-Based Leaderboards
Many games use Elo scores to create leaderboards that rank players based on skill level. These leaderboards provide a competitive atmosphere and motivate players to improve their skills.
How Is Elo Calculated?
The Components of Elo
Expected Win Probability
The expected win probability is calculated based on the Elo scores of the players or teams involved. The higher the Elo score, the higher the expected win probability.
Actual Win or Loss Outcome
The actual win or loss outcome is the result of the match. If a player or team wins, their Elo score will increase, and if they lose, it will decrease.
Formula for Calculating Elo
The formula for calculating Elo is as follows:
New Elo Score = Current Elo Score + K * (Actual Score – Expected Score)
Where K is a constant that determines how much the Elo score changes after a match, Actual Score is the actual win or loss outcome, and Expected Score is the expected win probability.
Explanation of How Elo Is Adjusted Based on Wins and Losses
The amount that the Elo score changes after a match depends on the difference between the actual and expected scores and the value of K. If a player or team wins a match with a high expected win probability, their Elo score will only increase slightly. However, if they win a match with a low expected win probability, their Elo score will increase more significantly.

Controversies Surrounding Elo
Criticisms of Elo
Limited Accuracy
One criticism of the Elo system is that it can be inaccurate when used in multiplayer games that have too many variables to consider. The Elo system only takes into account whether a player wins or loses, but it doesn’t consider other factors like player performance or team dynamics.
Inability to Account for Player/Team Improvement
Another criticism of the Elo system is that it doesn’t take into account a player or team’s improvement over time. If a player or team improves significantly but doesn’t win many matches, their Elo score won’t accurately reflect their skill level.
Alternative Ranking Systems
TrueSkill
TrueSkill is a rating system developed by Microsoft Research that is based on Bayesian inference. It takes into account player performance and team dynamics, making it more accurate for multiplayer games.
Glicko
Glicko is a rating system that is similar to Elo but takes into account the rating deviation and reliability of the players or teams involved. This makes it more accurate for games that have infrequent matches or large skill gaps.
Conclusion
To sum up, Elo is a rating system used to calculate the skill level of players in various competitive games. It provides a clear way to track progress and improvement, and it allows players to compete at a similar skill level. While there are some criticisms of the system, it remains a popular and effective way to rank players in many games.
