Bug reports: the calculator isn’t working, a page looks broken, or a number doesn’t look right. Please include your browser, your device, and the stats you entered so we can reproduce the problem.
Feedback and suggestions: ideas for new features, guides you’d like to see, or improvements to the tool.
Content corrections: League of Legends changes often. If you spot something outdated or inaccurate in one of our guides, let us know and we’ll review it.
Business and partnerships: collaborations, sponsorships, or advertising inquiries.
Privacy questions: anything related to our Privacy Policy.

We can’t look up or change your account. MMRCheckerLoL is an independent fan-made tool and is not affiliated with Riot Games. For account, ban, or in-game issues, please contact Riot Games Support.
We can’t tell you your exact MMR. Riot doesn’t publish it, so our calculator only provides an estimate based on the stats you enter. You can read how it works in our MMR Checker guide.

We’re a small independent project, so replies may take a little longer during busy periods. Thank you for your patience.
