Just like most of the competitive online multiplayer games in the world, Dota 2 also has its own ranking system. These ranked matches basically put players into a number of different competitive tiers. These tiers are represented in the form of leagues and their medals. The medals and their associated league names can be seen on the profile of every player. This percentage is increased whenever a player wins a match, and reaching percent takes the player to a new level. Once a player reaches the next level, he is then placed into the next tier with a one-star medal.
