This type of matchmaking is used in tournaments and any other competition that has to select opponents of similar skill levels.

Ranked matchmaking is based on the Elo rating system.

{{Notice
|A tournament participant can see their rank at the portal at https://tss.warthunder.com/ by logging into their account and clicking “Rating” in the menu. Rating is calculated individually for each game mode and difficulty level. A rating is given if the player has completed at least one battle in a relevant tournament.}}

== Rating Generation ==
Each player starts with a rating of 1,000 points. Later, the rating is calculated based on tournament battle results, using this formula:

Where

* ЕА is the expected value (from 0 to 1) for the number of points Player A will earn in a game with Player B
* RA is Player A’s rating
* RB is Player B’s rating

The rating points for Player A are calculated based on the outcome of the match:

Where

* RA is Player A’s rating after the match
* RA is Player A’s current rating
* SA is the number of points gained as a result of the match (1 for a victory, 0.5 for a tie, and 0 for a loss)
* K is a fixed coefficient with a value of 10

{{Notice
|Team ratings are calculated as the average rating of all players registered in the team.}}

== An example of formula calculations ==
Only victories and defeats in tournament battles or other competitions affect player ratings in War Thunder. Actions taken during the battle have no effect on ratings.

Let’s say that Player A has a current rating of 1225 points and Player B has a rating of 925.

The expected result for Player A would be:

Player B’s expected result would be:

If Player A wins the match, we get these results:

R’A = 1225 + 10 * (1 - 0.85) = 1225 + 1.5 = 1226.5

R’B = 925 + 10 * (0 - 0.15) = 925 - 1.5 = 923.5

If Player B wins, the result will be:

R’A = 1225 + 10 * (0 - 0.85) = 1225 - 8.5 = 1216.5

R’B = 925 +10 * (1 - 0.15) = 925 + 8.5 = 933.5

So, an experienced player with a high rating gets a much smaller gain for winning against a weak player than a weaker player who defeats a strong opponent.
