How official competition is scheduled: Daily runs Monday through Friday (UTC), scored on completion and accuracy — no Ranking Points. Weekly Cup runs every Saturday except the third, and earns Ranking Points toward your Season. Grand Tournament replaces that week's Weekly Cup on the third Saturday of each month — one competition, not both — earns Ranking Points, requires a verified identity to enter, and counts toward your Grand Circuit. Sunday has no scheduled official competition. Exact opening and closing times for each event are published by the event service as they're confirmed.
