What Is MMR in League of Legends?
The hidden rating League of Legends uses to estimate your skill, build fair matches and decide how much LP you gain or lose.
What is MMR in League of Legends?
MMR (Matchmaking Rating) is a hidden number Riot uses to estimate your skill. It goes up when you win and down when you lose, matchmaking uses it to find players at your level, and the gap between your MMR and your rank decides how much LP each ranked game is worth.
How MMR works
Every game you finish updates your MMR. Beating opponents who were expected to win raises it more than beating weaker ones, and losing to weaker opponents costs more than losing to stronger ones.
Riot keeps the number hidden. What you see in the client is your rank: a tier, a division and your League Points. Rank is the visible layer built on top of MMR, and over time the two are meant to line up.
MMR vs. rank
| MMR | Rank | |
|---|---|---|
| Visible in the client | No | Yes |
| What it represents | Riot's estimate of your skill | Your position on the ranked ladder |
| How it changes | After every game, based on the result and the opponents | Through LP gains and losses, promotions and demotions |
How MMR affects your LP
When your MMR is higher than your rank, wins give more LP and losses take less, so you climb toward the level the system thinks you belong at. When your MMR is lower than your rank, the opposite happens: smaller gains, bigger losses. Once MMR and rank are close, gains and losses even out.
This is also why LP gains are often high at the start of a season: after the reset, most players' MMR sits above their new rank.
Example
Two players are both in Gold II. One keeps beating higher-rated opponents and gets large LP gains per win. The other keeps losing to lower-rated opponents and gets small gains with big losses. Same rank, very different MMR.
Each queue has its own MMR
Normal games, Ranked Solo/Duo and Ranked Flex each track a separate MMR, so a losing streak in Flex does not touch your Solo/Duo MMR. The one link between them: your normal-game MMR is taken into account for your first ranked placement.
How to raise your MMR
- Play for consistency. MMR reacts to your results over many games, not to a single streak.
- Keep a small champion pool so your performance is stable from one game to the next.
- Stop after a couple of tilted losses. Losses lower MMR just as reliably as wins raise it.
If you would rather skip the grind, our Division Boost can take your account to the rank you are aiming for.
Frequently Asked Questions
Can I see my MMR in League of Legends?
No. Riot does not show MMR anywhere in the client. Third-party sites can only estimate it from match history, so treat their numbers as rough approximations.
Why do I gain so little LP per win?
Small gains usually mean your MMR is below your current rank. Keep winning and your MMR rises, and your LP gains grow with it.
Does playing Flex affect my Solo/Duo MMR?
No. Solo/Duo, Flex and normal games each have their own MMR, so results in one queue do not change the others.
