| Signal | Low | Stable | High |
|---|---|---|---|
| Win rate | Under 48% | 50 to 55% | 55%+ |
| Streak | 3+ losses | Flat or 1 win | 4+ wins |

MMR stands for Matchmaking Rating. That is a hidden number that uses League of Legends. These numbers work as a behind-the-scenes system for players.
They measure the real skill of people. Riot Games uses every secret rating to match players with similar opponents. Without this system, anyone could play against anyone, what could create fights between new players and aces.
What is MMR in League of Legends
The mechanism ensures fair, balanced matches in this MOBA game for each.
MMR is different to visible rank. The ranks show: Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, Master, Grandmaster or Challenger. Although rank shows, MMR really controls the matches.
It chooses against who players you match. Also it sets how much LP you win after victory. LP stands for League Points, that helps to move through ranks.
You get LP because of victories and lose because of defeats. The amount depends on your real rank and MMR. Usually rank changes more quickly than MMR.
Even so only MMR controls, with whom you play.
When a player deserves his rank, his MMR matches it. Then gains and losses of LP match. If MMR is a lot low compared to rank, you get only little LP.
Losses then are big. So a player must win many games so that MMR catches up until the rank. To fix MMR, you need a series of victories or fewer defeats.
You can guess his MMR according to ranks of opponents. If they match to your rank, everything is normal. This way is the only one to check yourself.
New accounts or those without prior yearly rank have skill estimated according to Normal game MMR, ARAM MMR and Co-op versus AI. KDA does not directly change MMR. You can check secret MMR in ranked, normal and ARAM games by means of tools and calculators.
Some tools show MMR of the last 10 ranked games right away.
