Current matchmaking systems depend on a single core strategy: create fair games at all times. These systems pair similarly skilled players on the assumption that a fair game is best player experience. We will demonstrate, however, that this intuitive assumption sometimes fails and that matchmaking based on fairness is not optimal for engagement.
Player engagement can be embodiedby many specific metrics, such as time or money spent in the game,the number of matches played within a time window, or churn risk.
By formulating matchmaking into an optimization problem, we pair players in order to maximize the overall player engagement, or equivalently, minimize the overall player disengagement.
First, we measure a player’s disengagement by their churn risk after each matchmaking decision. Here churn refers to no gameplay within a period of time, such as a week.
Reminder to only play non-ranked game modes, don't fall for the jewtrap, take the quick-play pill!
