PLR stands for Players' Lounge Rating. It's an indicator of how good a player is at a game. The higher the PLR, the better the player! This helps you find matches that you know will be competitive and avoid matches where you're going to get blown out.
You earn your your PLR after completing 3 money matches. We use an algorithm that takes into account the number of wins and losses a player has, as well as the strength of their opponents. Your PLR is adjusted as you play more games on the site.
