Matchmaking Rating

Info

A player`s match history, showing changes in MMR after each game.

Matchmaking Rating, or MMR is a value that determines the skill level of each player. This value is used in matchmaking. Winning increases a player`s MMR, while losing decreases it.

Players with the highest ratings are listed on the world Leaderboards The top ten of Europe in Jun. 2016. Public Leaderboards are Valve s official rankings of the top 200 players in four world regions. Rankings are determined by a player s Matchmaking Rating (MMR) in solo ranked .

Matchmaking

In general, players with similar MMRs will be matched with each other. Five MMR values are tracked independently:

• Solo rating (Normal games)
• Party rating (Normal games)
• Solo rating (Ranked games)
• Party rating (Ranked games)
• Team rating (Ranked games)

MMR for ranked matches require approximately 10 games to calibrate. Players who rank in the regional top 200 for solo ranked matchmaking will appear on the Leaderboards The top ten of Europe in Jun. 2016. Public Leaderboards are Valve s official rankings of the top 200 players in four world regions. Rankings are determined by a player s Matchmaking Rating (MMR) in solo ranked .

Valve

In Dec. of 2013, Valve This topic is covered better by other wikis or sites. Please see the following links instead: Valve Corporation on Wikipedia Valve on the Valve Developer Wiki Valve Corporation Company Year Founded Aug. 24, 1996 Management gave the following MMR distribution for solo unranked matchmaking across the entire player base. It is unknown how much these figures have changed since 2013.

Percentile indicates the percentage of players who are lower than the corresponding MMR. For instance, a player with 3200 MMR would be more skilled than 90% of the total population.

OpenDota

Subsequent analysis of public player profiles collected by OpenDota shows a higher average MMR of approximately 3100. 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.
• New accounts with few games played tend to have high uncertainty, while older accounts with many games played tend to have low uncertainty.
  • Since normal and ranked matchmaking are tracked separately, a player who has many normal games will still experience high uncertainty in ranked matchmaking if he or she has only played a few ranked games, and vice versa.
• Higher uncertainty leads to larger MMR adjustments after each match, and lower uncertainty leads to smaller adjustments.
• Highly uncertain matches are sometimes called swing games because their outcomes are "breakthrough" moments that are indicative of a player`s MMR progression or regression.
• If game outcomes (win/loss and individual performance) repeatedly match the system`s expectations, uncertainty will decrease until it reaches a floor.
  • Conversely, unexpected match outcomes will cause an increase in uncertainty.

Party

In general, parties “ Play Now it s a party! Click to listen— Storm Spirit ” Players can form parties to play matchmaking games with each other on the same team. Unlike a Guild or a Team, parties are not formalized receive bonus MMR when searching for matches. This is meant to compensate for superior party coordination, as well as partying with highly skilled members.

• Parties` skill and experience values are counted as an aggregate, not individual for each player.
• Parties will receive a higher adjusted MMR.
• Parties with large differences between members` MMRs will receive a higher adjusted MMR.
• Party members with a solo MMR higher than their party MMR will receive a higher adjusted MMR.

Updating

MMR will not be changed if:

• A non-partied member of your team early abandons For Hero Strength, Agility, and Intelligence, see Attributes. Stats are a record of the player s Wins, Losses, and Abandons. They are displayed on the player profile. Contents 1 Wins and Losses 1.1 Game Modes 1.2 a normal match.
• Poor network conditions have been detected. A message must appear in game in order for this to apply.

MMR will be changed if:

• Any member of your team See in-game grouping. For competitive teams, see List of professional teams. A Team is an in-game function to form designated groups. Unlike parties, teams have a fixed identity and do not disappear late abandons.
• Any member of your party “ Play Now it s a party! Click to listen— Storm Spirit ” Players can form parties to play matchmaking games with each other on the same team. Unlike a Guild or a Team, parties are not formalized abandons in any form.
• You are playing a ranked match, regardless of any abandons.

Visibility

• The average ranked MMR for both teams is displayed on the hero selection screen during a ranked match.
  • The highest individual MMR is also displayed during hero selection.
• Ranked individual MMR for all players are displayed on the endgame screen after a ranked match.
• Unranked individual, team and party MMRs are always hidden.

Other Information

• MMR is the principal, but not the only factor used in matchmaking.
  • The system also takes into account Experience (number of games played), Player Performance, Gold Difference and various hidden variables.
• The system does not directly try to achieve any particular win rate for players.
  • Be that as it may, it does try to ensure that each team has a 50% chance of winning by matching players of similar skill against each other.
    • This means that, over time, win-loss ratios will naturally settle around 50/50 for all but the very best players.
• The system does not examine individual win / loss streaks or try to end them.
• Win rate and win count are not related to MMR, nor are they meaningful measures of player skill.

Trivia

• According to Valve, player opinions of the MMR system are highly correlated with their recent win rates.
