How the MMR checker works

  1. Enter your Riot ID

    Pick the region you play on, the queue, and type your Riot ID with its tag.

  2. We read your ranked stats

    We look up the public data of that queue: rank, LP, wins and losses this season.

  3. See your estimated MMR

    Your rank and LP become a rank MMR, and your win rate moves it up or down to the estimate.

What is MMR

MMR (matchmaking rating) is the hidden number League of Legends uses to match you with players of a similar level. Your visible rank and LP follow it, but they are not the same thing.

Riot does not show MMR anywhere, so every MMR checker gives an estimate. Ours is built from public ranked data only.
