Elo

Elo acts as the rating system for the Ranked game mode in Brawlhalla. Elo is used in matchmaking queues to find players with a similar skill level to you.

Elo is gained or lost by winning or losing a Ranked match respectively. The amount won or lost depends on the opponent's Elo. If your opponent has much more Elo than you, winning the match will result in higher Elo gain than usual, and losing the match will result in a lower Elo loss.

Elo is used for competitive matchmaking to match players with similar Elo ratings, and to determine how much Glory is awarded to the player at the end of a season.

Calculating Elo

The following formula is used to calculate Elo gain for a player:

$New Elo = Current Elo + K \times (Score - Chance)$

where:

$K$ is 32 at or below 2400 Elo, and 10 above 2400 Elo. $K$ is tripled for players while playing Placement Matches

$Score$ is 1 if the player wins, 0 if the player loses

$Chance$ is the player's chance of winning, calculated by the following formula:

$Chance = \frac{1}{1 + 10^{(Enemy Elo - Current Elo)/400}}$

If $New Elo$ is a fractional number, it is rounded to the nearest whole number. If the result of $New Elo$ is below 200, $New Elo$ will be set to 200.

This formula is used for Ranked 1v1, Ranked 2v2, and seasonal gamemodes. For personal Elo ratings in Ranked 2v2 and seasonal gamemodes, $Enemy Elo$ is determined by the average Elo of all opposing players, and is then used to calculate $Chance$.

Additionally, 2v2 Team rating can increase drastically if the average of the two players' Personal rating is much higher than their Team rating.

Soft Reset

At the end of each season, all players above 1400 Elo undergo a soft reset (also called Elo squash). This lowers the player's current Elo rating to reduce the gap between the highest and lowest Elo players.

New season Elo can be calculated using Brawlhalla's Elo Squash Calculator.

There are different formulas used to calculate a player's new Elo, depending on their current Elo:

• Personal 1v1/2v2, 1400+ Elo :

$New Elo = 1400 + \frac{Current Elo - 1400}{3 - (3000 - Current Elo)/800}$

• Legend/Team, 200-2000 Elo:

$New Elo = \frac{Current Elo + 375}{1.5}$

• Legend/Team, 2000+ Elo:

$New Elo = 1583 + \frac{New Elo - 2000}{10}$

If the result of $New Elo$ is a fractional number, it is rounded down to the nearest integer.

Trivia

• In most other games (most prominently chess), a $Score$ value of 0.5 is used in the event of a draw/tie. However, Brawlhalla simply favors and picks Player/Team 1 as the winner(s).
