Does anyone know how to check mmr?

Sure! You should try the check mmr league of legends tool at AgataSmurf. It goes deeper than the client, which doesn’t really tell you your hidden MMR. This one looks at trends across games—whether your objective play, kill/death balance, and consistency are pushing your rating up or dragging it down. It’s more than just a number; it’s an explanation of why matchmaking feels the way it does. Perfect if you’re trying to improve step by step and want a clearer idea of your real standing.
