LearnClash uses ELO-based matchmaking. You're matched with players within ~200 ELO of your rating. If no match is found within 30 seconds, the range expands. Friend duels bypass matchmaking entirely.

You lose ELO when you lose a duel or disconnect during a match. The amount depends on your opponent's rating—losing to a lower-rated player costs more points. Draws result in small ELO changes.
