Ranked Matchmaking is Coming The next major update will add a ranked matchmaking feature to the game. This mode is aimed at experienced players who want to play in a more competitive environment and know their matchmaking rating MMR. Dota 2 matchmaking has always calculated MMR and used it to form matches; in ranked matchmaking we make that MMR visible. Ranked matchmaking is unlocked after approximately games. All players in the party must have unlocked the mode. You may not participate in ranked matchmaking while in the low priority pool. Coaches are not allowed in ranked matchmaking.
This figure is assumed to be skewed upwards, as it is generally believed that newer and less skilled players are less likely to display their MMR publicly, and therefore are not considered in the data analysis. Uncertainty Uncertainty is the standard deviation of a player's MMR. Players with high uncertainty are more likely to be matched with players that differ more greatly in skill level, and vice versa.
