The matchmaking rating (MMR) is a number used by Riot Games to indicate a player\u2019s skill level in League of Legends<\/em>. A summoner\u2019s MMR is determined by their performance in the game, and although there\u2019s no certain way to know how it\u2019s calculated, players with a stable winning streak have seen an improvement in their MMR.<\/p>
The MMR also determines the levels of the player\u2019s teammates and how strong their opponents will be. The system will place people with similar MMR in the same match to improve the game experience for everyone. Since League <\/em>has different game modes, players will have a unique MMR for each mode. <\/p>
