ELO Rating System

Mordhau uses a standard for both of it's ranked game modes, Duel and Teamfight. Every 100 Match Making Rating (or MMR) will grant you a new Rank.

The Elo rating system is a method for calculating the relative skill levels of players, originally designed for two-player games such as chess. It is named after its creator Arpad Elo, a Hungarian American physics professor and chessplayer. The Elo system was invented as an improved chess rating system, but today it has been adapted for use in many other games. Variations of it are also used as a rating system for multiplayer competition in a number of games and has been adapted to team sports including association football, American college football and basketball, and Major League Baseball.

In Mordhau, the rating system works slightly differently for each of the two Ranked modes. The amount you gain is not directly what your opponent loses, as the game tends to remove a small amount as a tax, typically between 1-3 MMR each game. Leaving a ranked match early will lose you MMR, as well as give you a X minute ban from Ranked servers.

=Duel=

In a 1v1 Duel, the rating system is quite straightforward. Two players are matched up based on their relative MMR scores, with the game searching for an opponent up to 500 points higher or lower than your rating. A formula is then used to make a prediction of what score both you and your opponent should get, based on the relative difference between your ranks. This prediction for how the match should end, is then used to compare to the final result of the match. If the result was close to the predicted result, the relative gain/loss would be small. If however you performed much better than the prediction suggested, such as defeating a player of much higher rank, then your gain, and their loss would be considerably more.

=Teamfight=

In a 3v3 Teamfight, the system works a little differently to account for it being a team mode. 6 players are still roughly matched up based on their relative MMR scores, but players in a party will be matched up only by the player with the higher MMR value in the party, which can result in lower ranked players facing much more skilled opponents, if they play with a higher ranked friend. The matchmaking search range is still 500 MMR for this gamemode. A prediction is made, similarly to the Duel system, but in this case, it is a prediction of how well your entire Team should perform relative to the opposing team. The gain and loss of MMR is evenly divided between the players, and is not proportional to players individual performance.
