Matchmaking rules

Here's how the matchmaking works:

Get the 100 "oldest" (creation time) available matches matching these conditions: Opponent's league has to be between <your league> -1 and <your league> + 1 If opponent's league is different than yours: league score delta has to be lower than 200 points Filter out (remove) matches matching these conditions: Opponents has already been played in the last 5 minutes 2 possible cases: If there's no match remaining: Pick a random map Pick a random left/right side Create a new match using these parameters If there's some matches remaining: Sort the remaining matches using these comparison rules: Opponent in the closest league first In case of equality: opponent using a different IP first In case of equality: opponent never met or met the furthest in the past first (considered equal under a 10 minutes delta) In case of equality: opponent with the lowest league score delta (compared to yours) first (considered equal under a 10 points delta) In case of equality: oldest match (creation time) first Take the first match of the list and join it
