MMR in LoL: The Backbone of Competitive Play

For those who are not familiar with the game, League of Legends is a multiplayer online battle arena game that is enjoyed by millions of gamers all over the world. It requires a great deal of skill, strategy, and teamwork in order to win. However, a lot of players are confused about how the matchmaking ranking or MMR works in the game. In this blog post, we will decode MMR in League of Legends and give you a better understanding of how it works

MMR (Matchmaking Rating) is a system that is used to determine the skill levels of players in League of Legends. It is essentially a number that determines how good a player is compared to other players. The rank system works in such a way that players with higher MMR will be matched against players who have similar MMR. In short, MMR is one of the biggest factors in determining who you will play against in the game.

Every player starts off with a certain MMR which is determined by their performance in their first few games. From there, the system will continue to adjust their MMR based on their wins, losses, and their performance in each game. For example, if a player wins a game, their MMR will increase, but if they lose, their MMR will decrease. The amount that the MMR changes will depend on the skill levels of the players involved, and the likelihood of winning or losing based on those skill levels. 

The MMR system is designed to be highly accurate in making sure that players are placed against opponents of similar skill levels. This is why players who are new to the game will often be matched against other new players, while experienced players will be matched against other experienced players. The system ensures that players are matched against others who are as equally skilled as they are, which translates to a better gaming experience for everyone.

One thing to keep in mind is that MMR takes a lot of different factors into account. It’s not just about how many games you win or how often you play, but also how well you perform in each game. The MMR system recognizes and rewards players who perform well, even if they don’t win all the time. This means that even if you lose a lot of games, you can still increase your MMR by performing well in those games. And vice-versa; if you win a lot of games but perform poorly, your MMR may not increase as much.

It’s important to remember that MMR is not a perfect system, and there are occasional issues with it. Sometimes, players may be matched against opponents who are significantly better or worse than they are, which can make the game frustrating and unenjoyable. However, these instances are few and far between, and the MMR system is constantly being updated and improved to make the game experience as fair and fun as possible.


So there you have it, a brief but detailed explanation of how MMR works in League of Legends. Understanding the MMR system is crucial if you want to succeed in the game, and it can give you a much better idea of your own skill level. Keep in mind that MMR is just one factor in determining the outcome of a game, and that skilled players can still win games against opponents with higher MMRs. But knowing how the system works can help you get better, and lead you to a better gaming experience overall.
