The Glicko Rating System: A Dynamic Approach to Esports…

What is the Glicko Rating System?

The Glicko rating system, developed by Mark E. Glickman, is a method for ranking players based on their performance over time. It extends the Elo rating system to account for varying levels of player uncertainty and volatility.

In esports, this system allows for dynamic updates in ratings after each match, ensuring that the rankings reflect current skill levels accurately.

How Does the Glicko-2 System Work?

The Glicko-2 system uses a logistic function to predict the outcome of a game between two players based on their ratings and uncertainties. The rating update formula takes into account the actual match result, the predicted probability of winning, and the player's uncertainty.

This approach ensures that players with higher uncertainties have more significant changes in their ratings after successful performances, while those with lower uncertainties maintain stable rankings.
