The Elo rating for ranked games was different for each type of queue: 3v3 arranged, 5v5 solo and 5v5 arranged teams. The rating was only visible for ranked games after 5 games played in a certain queue type. Players were awarded with medals in their summoner profile based on their Elo at the conclusion of a season. Medals were given as follows: [2]. About a month before the end of Season 2, a new rating tiers system was introduced: [3].
These are sectioned off every seventy points of elo is Silver V, is Silver IV, etc. Season Two Rating Tiers. The specific formulas which were used for Elo calculations in League of Legends are unknown. However, most Elo implementations share the same basics as that originally designed for chess. A brief summary is given below. For a more detailed discussion, see Wikipedia. It is assumed that a person's performance varies from game to game in approximately a normal distribution and a person's Elo rating was the mean of that distribution.
A person with a higher Elo may perform better on average than a player with a lower Elo, although usually it was mainly to do with the teamwork around that player. For players A and B with respective Elo ratings of Ra and Rb the expected victorious outcome Ea of the game for player A was given by the following formula:.
This standard is for Chess and may have been different in League of Legends. If you have a good win rate, the system will allow you to skip promotions or divisions to ensure that you reach your real rank as fast as possible. If a player continuously loses games, they also run the risk of eventually dropping back down to zero LP. In this case, a player could be demoted to the division below them, unless they can win some matches again.
This number is different from your actual ranking. Riot uses it as a way to determine how much LP you should gain or lose. Winning game after game can cause your MMR to rise while losing several games in a row can cause your MMR to decrease rapidly, affecting the amount of LP you can get per match. You can also lose LP by being inactive for a long period of time. Professor Elo spotted the flaws in the old system and used his findings to develop a new system.
Based on the data, if a player wins more games than expected, their rating goes up. If they lose a lot of matches, their rating goes down. Each competitive game uses a modified version of the Elo system. Different games take different metrics into consideration.
PUBG is one of the few games that uses the original Elo system. Winning increases the rating and losing decreases it. But back in , a Valve employee let slip that CS:GO initially based its matchmaking on the Glicko-2 ranking system, though it has since been adapted and improved, involving some heavy modifications. Designed for player vs player competitions such as chess, each combatant is assigned a number to represent their rank.
Glicko-2 is one such alternative, assigning a Ratings Deviation RD around a base number. The better the system knows your real rank, the smaller this range will be. However, despite Glicko-2 being an open system, clear limitations stop it from applying directly to CS:GO ranks.
Both Elo and Glicko were designed with 1v1 competition in mind. In a 5v5, team-based game, far more factors come into play. Sure, one player can earn four kills in a round, but that may only be because of an ally securing the bomb-plant, or placing a well-timed flash.
In response to this silence, some players have their own theories on how CS:GO ranks work. Back in , Steam user RetriButioN posted a lengthy record of his experience ranking up multiple accounts.
