What is MMR in League of Legends?
Matchmaking Rating (MMR) is a hidden score used by Riot Games in League of Legends to evaluate player skill and create balanced matches. This system ensures players face opponents of similar skill levels, making games more fair and enjoyable.

For example, if your MMR is 2000, you will generally be matched with players whose MMR is close to that number. While the exact value of MMR is not publicly visible, there are tools and methods to estimate it.

How to Check Your MMR
Using an MMR Checker Tool

You can estimate your MMR using third-party tools like https://lolmmr.com/. Here's how:

  1. Enter your Summoner Name and Tagline (e.g., PlayerName#NA).
  2. Select your region.
  3. Click “Check” to view your estimated MMR.

    4. The tool calculates MMR based on match history, win/loss ratios, opponent skill levels, and other factors, with an accuracy of over 95%.

    Manual Estimation

    If you prefer, you can estimate your MMR manually:

    • High MMR Indicators: Frequent matches against higher-ranked players and gaining significant LP (League Points).
    • Low MMR Indicators: Matches against lower-ranked players and minimal LP gains or significant losses.
    • Normal MMR Indicators: Consistent matches with similarly ranked opponents and stable LP changes.
      • Why Your MMR Might Be “Unranked” or “Unable to Calculate”
      • Unranked: You have not yet been placed in a ranked tier.
      • Unable to Calculate: This can occur if input details are incorrect. Ensure you:
        • Select the correct region.
        • Enter a valid Summoner Name and Tagline.
          • Factors Affecting MMR

          MMR is influenced by various aspects of gameplay, including:

          1. Win/Loss Ratio: Frequent victories increase MMR, while losses can decrease it.
          2. Performance: How well you perform in matches.
          3. Streaks: Winning or losing consecutive matches significantly impacts your MMR.

            4. Note: Dodging (leaving champion selection) does not affect MMR but incurs LP and time penalties in ranked queues.
