Gauging Your Game: A Detailed Guide on Checking MMR in League of Legends

The information in this article has been updated for 2024.

As an avid League of Legends player and high-elo, I’ve spent countless hours honing my skills, studying the meta, and immersing myself in the deep and intricate system that Riot Games has woven. Of the various systems embedded within the game, one has always intrigued me: Matchmaking Rating or MMR.

The Enigma of MMR

MMR, an internal Riot statistic, is a measure of your battlefield competence, ranging from 0 to 2500+. It is not a direct depiction of your rank or insignia, but it has a considerably greater impact on your gaming experience. MMR is the silent magician at the heart of the matchmaking process, ensuring you meet opponents of your skill level.

Despite its importance, many players, particularly newcomers, may wonder, “What exactly is my MMR?” and “How does it impact my gaming experience?”

MMR’s Impact on Your Gaming Journey

Your MMR directly affects your League points (LP) accumulation and the matchmaking process in ranked games. LP is the visible ranking score that players see after each game. With a higher MMR, you gain more LP for a victory and lose less upon defeat. Conversely, a low MMR means you’ll lose more LP when defeated and gain less when victorious.

How to Check MMR

Given that Riot doesn’t reveal your MMR, you have to resort to third-party sites to gauge your rating. Services like WhatismyMMR offer estimated MMR ratings by pulling data from LoL’s API. It’s important to remember, however, that these are estimates based on available data, not exact figures.

OP.GG, a widely-used site in the community, once offered an MMR estimate but has since replaced it with Rank Score or OP Score. This new system provides a more holistic view of a player’s performance without indicating their specific MMR.

MMR and Elo

MMR is often confused with Elo, a ranking system developed by Arpad Elo for chess, later adopted by many games and sports. The Elo system found its way into early seasons of League and was subsequently replaced with MMR, a more sophisticated version tailored for team-based games like LoL.

In essence, MMR and Elo serve the same purpose: determining a player’s skill level relative to others. The terms have now become interchangeable within the gaming community, often used to describe a player’s internal ranking.

Unraveling the Mystery: How MMR is Calculated

While the exact formula for MMR calculation remains a closely guarded secret to prevent exploitation, certain elements evidently influence it. Your performance in each match is the key determinant, with wins and losses having a significant impact.

What’s fascinating is that MMR seems to exhibit a snowball effect. Consistent victories or losses can result in substantial MMR changes. A win streak can push your MMR to new heights, whereas a losing streak might cause it to plummet.

Boost Your MMR

Increasing your MMR is a difficult attempt that needs continuous performance and clever strategy. A high victory rate is critical since it tells the system that you’re frequently going over your current rank’s opponents. This feedback may trigger the system to accelerate the increase of your MMR.

Victories, however, are insufficient. It’s all about accumulating victories and snowballing. Repeated victories show a performance pattern that suggests you’re better than your current MMR. As a result, the system is asked to update your MMR more quickly.

When seeking to elevate your MMR, emulate the gameplay of top-tier players. They are a testament to how strategic and skillful gameplay can positively influence MMR. Follow pro player streams, dissect their strategies, and learn from their in-game decisions. Incorporating these tactics into your gameplay can lead to an improved win rate, and by extension, an increased MMR.

Don’t forget the importance of understanding the current meta. Each new patch and season update brings changes that can shake up the game’s balance. Keeping up-to-date with these changes can give you an edge over opponents and impact your win rate and MMR.

Psychological Impact of MMR

While this debate may have peaked your interest in checking your MMR and working hard to raise it, it’s vital to consider the psychological consequences. An serious obsession with MMR can cause anxiety, tension, and a “ladder anxiety” phenomenon, in which players avoid playing ranked games in order to prevent potentially losing their MMR.

Remember, it’s just a game. While it’s natural to strive for improvement, don’t let a number define your enjoyment or dictate your gaming experience. Each player has good and bad games, and even the best can find themselves on a losing streak. These are opportunities to learn, adjust your strategies, and ultimately, grow as a player.


MMR may appear to be an enigmatic shadow hidden over your LoL experience, but understanding it and how it affects your path might give you a new appreciation for the game’s complexities.

While MMR is an important aspect of the competitive journey, don’t lose sight of why we all started playing League of Legends in the first place: for the love of the game. A higher MMR is a testament to your skill, consistency, and perseverance, but it’s the fun of playing, the excitement of team fights, and the satisfaction of outwitting opponents that keeps us coming back to League of Legends.

As we decipher the mystery of MMR together, I hope you continue to find enjoyment in the game. Remember, your MMR is not a measure of your worth but a reflection of your journey in the world of League of Legends. Here’s to the thrill of the game and the pursuit of constant improvement. Good luck on Summoner’s Rift, and may your MMR climb as high as your passion for the game.
