After a certain period, players are introduced into the main matchmaking pool. Players are initially placed in a separate pool, allowing them to play exclusively against other new players. In Casual mode and the Arena, new players are initially placed into special matchmaking pools to ease them into the game.Ĭasual mode matchmaking includes a new player pool. Tavern Brawl MMR does not reset, and carries over from week to week. Ranked mode MMRs are not reset at the start of every season. It is unknown whether or not cooperative Tavern Brawls (which do not use MMR for matchmaking) affect the player's MMR.

The amount of MMR gained or lost is dependent on the MMR of your opponent.

MMR is gained with wins and lost with losses.MMR is adjusted after each match, depending on the outcome of the match, and the MMR of each player: Tavern Brawls (except cooperative Brawls ).Ranked matches involving at least one player at Legend rank.Casual matches (shared between Wild and Standard format ).MMRs are used for the following types of matchmaking: MMRs are 'hidden' and cannot be viewed by players. Each MMR is determined independently and does not affect other types of play. Hearthstone uses separate MMRs for different types of play, such as Casual mode, Legend-level Ranked play, and non-cooperative Tavern Brawls. Matchmaking rating (MMR) is a special internal rating system used for certain types of matchmaking. įor information and statistics on specific types of matchmaking, see Ranked, Casual, and Arena. This ensures players are not left waiting for too long, but as a result, players may occasionally be matched with opponents of significantly different rating, rank, or record.

However, each time the system fails to find a match, its matchmaking parameters are widened. If a perfect match is not found, the matchmaking system will "wait a few seconds" and then search again. If one is found, the two players will be entered into a match with each other. When a player enters the matchmaking queue the system will attempt to find another player in the queue with an identical matchmaking value. The player's matchmaking value is the only data used in the matchmaking process: other details, such as class, deck, or playing history are not taken into account and never affect matchmaking. In each case, the goal is the same: to try to find a player of similar matchmaking value (rating, rank or record) as possible. Casual mode and the Arena feature special mechanics for very new players. Ranked play without a Star Bonus is determined by each player's rank, and Arena pairings are determined by each player's win/loss record for the current run. Casual mode, Ranked at Legend rank, and non-cooperative Tavern Brawls determine pairings using each player's matchmaking rating (MMR). The matchmaking process functions differently for each game mode. Matchmaking is the process of determining appropriate player pairings when players are queuing up to play Hearthstone.
