Matchmaking Screen

The matchmaking screen

Matchmaking is the process through which the system groups players into opposing teams for public games modes. With the exception of bot games, matchmaking is mostly determined by matchmaking ratings (MMR).


Valve has stated that matchmaking tries to fulfil several criteria:

  • The teams are balanced.
  • The discrepancy in skill between the most and least skilled player in the match is minimized.
  • The highest skill Radiant player should be close to the same skill as the highest skill Dire player.
  • The discrepancy between experience (measured by the number of games played) between the least experienced player and the most experienced player is minimized.
  • Each team contains about the same number of parties.
    • Five-player parties can only be matched against other five-player parties.
  • Players' language preferences contains a common language.
  • Wait times shouldn't be too long.


Normal Match[]

Unranked or casual games do not display matchmaking ratings and still doesn't track your MMR for solo and party queues.

  • All PvP game modes are available for unranked matches.

Ranked Match[]

Solo Queue Only Matchmaking Panel

  • Players can choose to be matched only against other solo queue players.
  • Players can select a specific role when queuing for ranked matchmaking.
    • Separate MMRs are maintained for Core and Support roles, although the two influence each other by a set percentage.

    • Parties with any player below the matches played requirement will not be able to queue for ranked matches.

Ranked Classic[]

  • Ranked Classic is the default ranked mode. It does not allow players to pick roles when queuing.

Ranked Roles[]

  • Ranked Roles allows players to queue for the role they want to play. This usually takes longer to find a match.
  • Role Queue is a function within Ranked Roles that allows players to find matches faster.
  • Players can earn 4 games for Role Queue every time they search for a match with all roles selected.
  • A maximum of 60 Role Queue games can be earned and stored.
  • When in a party, players earn Role Queue games if the party fulfills all roles between its players.
    • Two-player parties earn 2 games each.
    • Three-player parties earn 1 game each.
    • Five-player parties earn no games, but always enter Role Queue because they fulfill all roles.
    • Solo players or parties who queue for both Support and Hard Support will join the Role Queue but not earn extra Role Queue games.

Practice 1v1[]

This function matches you against another player in the Mid Lane. This match is over when one player dies twice, loses a tower, resigns or disconnects. Type gg in chat to resign.

Bot Match[]

This function matches you or your team against AI-controlled bots.

  • Co-op bot matches are always played in All Pick mode.
  • No MMR is tracked for bot matches.


Settings allow players to be matched only with others who have selected the same settings. Selecting more settings can significantly reduce wait time, as the system will be able to search for compatible players from a larger population pool.

You can select up to 3 regions.

Matchmaking Rating[]

Main Article: Matchmaking Rating

All PvP matchmaking is based on an Matchmaking Rating (MMR) similar to the Elo system. Players of roughly equal skill will be placed in the same game.



Main Article: Priority

Priority determines how quickly the player is matched with other players. There are 3 types of priority: high priority, base priority, and low priority. Players in low priority will not gain battle points from the match, will find games more slowly, and will only be put with other players in low priority. Low priority is a common punishment for abandonment. Base priority is granted to any player when they enter a matchmaking queue provided that they are not in low priority. High priority is granted when a player is returned to queue after a recently failed matchmaking attempt due to another player failing to connect to the game or declining the Ready Check.


Main Article: Ban

Players may be banned from matchmaking for a period of time due to several offenses.

  • Declining or failing to ready for a match.
  • Abandoning too many matches.
  • Poor in-game behavior.
  • Too many reports from other players.

Behavior Score and Account Flags[]


The console displaying a behavior score.

Match quality is presumably determined by a combination of the player's behavior score and their account flags value. Players with a high behavior score get matched with other players with a high score and vice versa. The account flags supposedly determine in which matchmaking pool a player should be, independently of their mmr and behavior score. The current behavior score and account flags can be checked using the Console through the commands

developer 1
dota_game_account_client_debug | grep behavior
dota_game_account_client_debug | grep flags

The behavior score shows as grades . Possible Grades are Normal (encompassing the scores formerly labeled as A+, A, B+, and B), C+, C, C-, D, and F. While Normal being the highest and F being the lowest. Valve has not disclosed how these scores are calculated, but abandons, reports and commends seem to play a role.

Account flags are represented as an integer value. Most players report having an account flag value of 0, 1 or 3. It is known that account flags with values 7 indicates that a 6-month ban is imminent on the account, but there is no known effect on matchmaking.

Players with behavior scores below 3000 will be muted and cannot use voice or chat.
