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
