If you're a League of Legends player, then you know how important your MMR (matchmaking rating) is. It's a key metric that determines who you're matched up against in games, and having a high MMR can give you a significant competitive edge. So what is an MMR checker? It's a tool that allows you to input your league of legends username and view your current MMR. This can be extremely useful for players who want to track their progress and see how their MMR changes over time.
