Questions
FREQUENTLY ASKED QUESTIONS
Most commonly asked questions about League of Legends MMR and LP, answered.
What is MMR in League of Legends?
MMR (Matchmaking Rating) is the hidden number Riot Games uses to decide who you play with and against. It is not the same as your visible rank: your LP gains and losses are driven by how your MMR compares with the rank you currently sit at. A player whose MMR is above their rank gains more LP per win and loses less per defeat.
Can anyone see my exact hidden MMR?
No. Riot's public API exposes your tier, division, LP, wins and losses, but never the raw MMR value, and no site has access to it either. Any tool claiming to show your exact hidden MMR number is estimating it. We prefer to be straight about that and show you measurements we can actually stand behind.
What does this tool actually measure?
Two things. First, where you sit on the ranked ladder as a single score built from your tier, division and LP, compared against the midpoint of your own division. Second, your real LP change per game: we store your standing when you check, and the next time you come back we divide the difference by the number of ranked games you played in between.
Why do I see no trend on my first check?
Because a trend needs two points in time. On a first check there is nothing to compare against, so you get your rank, LP and win-loss record without a climb score. Play a few ranked games, come back, and the LP per match figure appears — measured from your own history rather than estimated.
What is LP and how does it relate to MMR?
LP (League Points) is the visible 0-100 bar inside each division. You gain LP for wins and lose it for defeats, and the size of each change depends on your hidden MMR. Steady gains near 20 LP with small losses suggest your MMR sits above your current rank; small gains with heavy losses suggest the opposite.
Is it free, and do I need to log in?
It is completely free and you never hand over your Riot account. We only read data Riot publishes through its official API using your Riot ID, so there is no password, no authorisation screen and no access to your account.
Does checking my MMR break Riot's Terms of Service?
No. The tool reads public data through Riot's official API, which is exactly what that API exists for. Nothing is automated inside the game client, no credentials change hands, and your account is never touched.
Why is there no climb score for Master, Grandmaster and Challenger?
Above Diamond the LP bar no longer stops at 100 — a Challenger player can sit on thousands of LP. Comparing that against a division midpoint built for a 0-100 bar would always read as wildly above average, so we leave the comparison out for those three tiers instead of showing a number that means nothing. Your rank, LP and record still display normally.

More Details about the LoL MMR Checker
Our League of Legends MMR checker exists to answer a question the game itself never answers directly: is your rank actually keeping up with how you are playing right now? Riot keeps your Matchmaking Rating hidden, so the only honest way to read it is through its effects — how much LP you earn per win, how much you drop per loss, and where you sit inside your own division.
Every ranked game you play is scored by a hidden Matchmaking Rating. It decides your teammates, your opponents and the size of every LP change, but it is never shown in the client. Your visible ladder position runs Iron, Bronze, Silver, Gold, Platinum, Emerald, Diamond, Master, Grandmaster and Challenger, with four divisions per tier below Master and a 0-100 LP bar inside each one. When your hidden rating outpaces that visible position, the client hands you larger LP gains and smaller losses until the two line up again.
Rather than inventing a hidden MMR number, this tool measures what can be measured. It turns your tier, division and LP into a single ladder score, compares that score against the midpoint of the division you are in, and stores the result. The next time you check after playing ranked games, it divides the change in your score by the number of games played and shows your genuine LP trend per match — your own data, not a model's guess.
That trend is what turns a static rank into something useful. A player averaging eight or more points a match is climbing quickly and will rank up in a handful of games; one hovering near zero is holding position no matter how many games they grind. Knowing which of the two you are is the difference between pushing on and stepping back to fix something in your play.
Why Use Our LoL MMR Checker?
- Measured, Not Guessed: Your LP per match comes from the difference between two real checks of your account.
- Honest About Limits: Riot does not publish raw MMR, so we never pretend to show it — we show what the data supports.
- Full Ladder Coverage: Every server and every tier from Iron IV to Challenger, including Emerald.
- Rank-Up Estimates: See how many games at your current pace stand between you and the next division.
- Free and Login-Free: Official Riot API data through your Riot ID — no password, no account access, no cost.
Whether you are grinding for Emerald or defending a Challenger spot, the useful question is not what your hidden number might be but which direction it is moving. Check your account, play your games, and check again — the trend you get back is measured from your own climb.
