Ranked ladder
Every format has its own ladder. Seasons last a month.
Loading the ladder
Play ranked
Open an online room or challenge someone from the online list and pick Ranked. Both players must pick it and be signed in.
Fair results
Both players' devices report the result. A duel counts when they agree, or when one player vanished for 10 minutes. Duels under 3 turns do not count.
Seasons
Everyone starts at 1000. Each month a new season starts from your rating pulled halfway back to 1000; your past ranks stay on your profile.
