Important Notice:
Due to recurring arguments with Community Members about the numbers formerly displayed on this page regarding the Skill Brackets and their surrounding mechanics, ALL numbers and values have been redacted from this page and will not return for the foreseeable future, also due to the general difficulty in keeping them up-to-date and accurate because of the inherently hidden and obscure nature of the MMR system in Dead by Daylight. |
The Skill-Based Matchmaking Rating, often abbreviated as "SBMM" or "MMR", is a hidden scoring system used to match Players together for ranked Trials in Dead by Daylight
.
The system has been in use since 8 September 2021 and replaced the previous matchmaking system, which had matched Players based on their Grades.
Overview
The Skill-Based Matchmaking Rating uses a hidden score that is influenced by the Player's performance in ranked Trials.
There is no way for Players to know their specific score.
The Skill-Based Matchmaking Rating is a shared value across all Survivors, but an individual one to each Killer.
This is the reason why Survivors can still switch characters when already matched, but Killers are locked to their selected characters.
Ranked Trial Mechanics
During ranked Trials, the Skill-Based Matchmaking Rating functions as a sort of game within a game.
In essence, each Survivor is in an individual mini-Trial with the Killer and vice versa, in which wins, losses, and draws can occur.
The game effectively tracks each mini-Trial, adds up the individual wins, losses, or draws, and calculates the change towards the Player's MMR score based on that.
Killer MMR-Rubberbanding
Each Killer has their own individual MMR score, which is the reason Players are locked to playing a specific Killer once the matchmaking process starts, prohibiting switching to another Killer.
Despite this, however, there is a rubberbanding-effect by which a Player's best-performing Killers will influence the score of all of their other Killers.
This is to prevent skilled Players from being matched with lower-skilled Survivors when choosing a Killer they do not play often or regularly.
It can be assumed that an experienced Player will perform reasonably well with most other Killers, despite not playing all of them equally often and matching them with inexperienced Survivors would not be fair.
This mechanic also automatically affects any new Killers the Player unlocks through purchasing DLCs.
