How challenges, matches, and scoring work.
Challenge anyone — no rank restrictions. Open competition for all.
Out of office — toggle on your profile to pause. Pending auto-reject, outgoing auto-withdraw, active matches cancel. No penalties.
Challenge expiry — challenges expire at the end of the last proposed time slot.
* Max committed challenges — active + outgoing challenges only. This is to ensure the league keeps moving.
At deuce (10–10), play until one player leads by 2 — e.g., 13–11.
Rankings use Glicko-2, an ELO-style system that also tracks how confident it is in your rating.
Placement matches — play 2 matches to get ranked. Until then you'll appear as "Unrated" at the bottom of the ladder. Your rating is tracked internally and will be revealed after your placements.
Rating — your skill level. Starting rating depends on your self-assessment. Win and it goes up, lose and it drops. Beating higher-rated players gives you a bigger boost.
Confidence — how sure the system is about your rating. The more you play, the more confident it gets, and the smaller your rating changes per match.
Inactivity — stop playing and confidence drops over time. Your rating stays the same, but when you come back, it can swing more until the system re-calibrates.
