About MMR In League of Legends

MMR ( Matchmaking Rating ) is a hidden score/rating used by Riot Games in League of Legends to identify the players’ skill level and to combine the players of similar MMR during Matchmaking to compete with one another, which makes the League of Legends games/matches more balanced and fair between players. 

For example, if your Matchmaking Rating is 2000, the system will include you with similar rating players during the Matchmaking process. 

More about MMR:

  • Smurf accounts: Some of the players in League of Legends do smurfing ( it means when an experienced player creates a new account ) when they feel that their MMR is not accurate or inconsistent, it helps them to start fresh.
  • MMR system updates: Riot Games is planning to implement the TrueSkill 2 system in League of Legends later in 2024, which is developed by Microsoft to improve the Ranked MMR, it will help each player to get to the right spot in the Ranked ladder, and it is expected that it will reduce the surfers and ELO hell problems. 

Why League of Legends Uses The MMR System

This is an infographic image that shows why MMR ( Matchmaking Rating ) is important in League of Legends.

League of Legends is a MOBA game that uses the MMR system to make the matches fair and balanced for all players, which means, through this system, newbies will face newbies in matches and professional players will face professional players in matches, which makes the games highly enjoyable for all of the players. 

But how does it make the matches fair? The answer is; that League of Legends combines the same skilled and MMR players during Matchmaking through this system for a playable experience, if your MMR is 2000 you will face the opponents of 2000 or similar MMR.

MMR system helps the game to combine the same skilled players during the Matchmaking process, which makes the matches highly equal and playable for all gamers of League of Legends. 

Note that the MMR system is not only used for improving Matchmaking but there also are more reasons, let’s know about them below: 

As we know, League of Legends is a big and old game that has a huge number of players, It is not an easy task for League of Legends to assign the right spot for all players on the ladder, so for this task, MMR helps them to represent the ranked tier and division of the players in the form of rating, which means that MMR is the overall summary of your current tier and division, if your ranked tier and division is high, your MMR will high too.

How We Calculate MMR

We estimate the players’ MMR by looking at their match history to know about their opponents’ skill level factors and Ranks.

We also analyze, the win/lose ratio, and how much LP the player has lost and gained, win-lose streaks for MMR calculations.

These factors help us to know about your skill level and your opponent’s skill level and yes it also helps us to make our tracker more accurate and precise, after the whole process, we estimate your rating with over 95% accuracy.

How To Identify Good And Bad MMR

MMR is hidden, but yes, you can use tools to get an idea about your score whether it is good or bad.

You can also get an idea by analyzing your matches. There are 2 factors that you should analyze, the first one is Rank and the second factor is LP gain and loss.

If your opponents have higher Ranks than yours and you are also gaining a good number of LP, then congrats, it is a good sign, it means that your MMR might be good.

On the other hand, if your opponents have lower Ranks than yours and you are also gaining less LP, then you should focus on improving your MMR because it might not be at a good stage.

Why MMR Does Not Increase After Winning Match

There are multiple factors that Riot Games considers while calculating the players’ MMR, such as victories, defeats, performance, winning streaks, losing streaks, win ratio, lose ratio, and more, these factors help them to know about your skill level more accurately.

MMR ups and downs depend on all of the factors included in the calculation algorithm, if you have met fewer factors, your score will increase accordingly, if you have met more factors your score will increase more.

So the main motive is that winning one match is not the only factor, you should meet other factors too.

Does Dodging Affect League MMR

Dodging is the act of leaving the game during champion selection, the good news is that it does not affect your MMR.

However, according to Riot Games, you will face time and LP penalties, which are mentioned below in an official image.

Dodging penalties, Source: official website.

In time penalty, Riot Games will not let you play the fresh match for some time after that you can play and enjoy the game. 

Dodging is not a good idea from the penalties perspective but it can be good if you are not comfortable with the team composition.

Another penalty is the LP loss, only in the Solo/Duo and Flex Ranked Queues. 

How MMR, LP & Rank Progress Together

LP, MMR, and Rank help the game determine the right spot for each player on the ladder. 

Here is how! 

Your MMR will be equal to Rank if you are losing and gaining the same number of LP. 

Your MMR will be greater than your Rank if you are gaining more and losing less LP. 

Your MMR will be less than your Rank if you are gaining less, and losing more LP. 

Note that this information is based on the official information of Riot Games so you can easily trust it.
