Matchmaking


The rating system in Battlegrounds is based on your matchmaking rating or MMR for short. It goes up if you placed 1st, 2nd, 3rd, or 4th, all of which counts as a win in Hearthstone Battlegrounds. The higher your MMR is, the more skilled your opponents will be. The lower it is, the less skilled they will be.

Battlegrounds MMR is calculated using a unique rating system. After each match, a player's rating gets updated based on a combination of things: the player's rating, the opponents' ratings, the player's place of finish, the player's predicted win chance, the player's variance, the consequences of a teamed group in the lobby, and other factors. Below 6500 rating, there is also a positive progression adjustment boost for each game a player plays, based on the player's current rating. This means that every game a player below 6500 rating plays will award a small boost to the player's MMR rating.

In November 2019, there were no plans to reset MMR, but a "normalization pass" might be done in the future to adjust players above 5,500 rating down to 5,500.

On March 8th 2020, Dean Ayala posted a Battlegrounds rating distribution for only players who had completed at least 5 games of Battlegrounds in the last 20 days:

Battlegrounds Parties
Battlegrounds Parties is an added way to enjoy the game of Battlegrounds by allowing players to queue with more than 2 other friends. Previously, only up to 2 players could queue together to search for a Battlegrounds game. Parties was added to the game on September 8, 2020 with Patch 18.2.

With the release of Battlegrounds Parties, now up to 4 players are able to queue for a ranked Battlegrounds match together. However, once the group lobby exceeds 4 players, the game type automatically switches to a private Battlegrounds match for 5-8 players.

While it may be fun to queue with up to 4 friends in ranked Battlegrounds matches, there are some downsides for the solo player matchmaking experience:
 * A group of friends can coordinate to power level and/or minimize loss of hero health whenever they are matched together.
 * The group is able to target solo players whom are dominating in a particular game.
 * The group has access to info which solo players won't, such as exact warband compositions for many of the players, and a better prediction of the composition of the shared pool of minions.
