Every match updates your rating for that club and your overall rating across every club you're in. Here's what moves the number.
Every player begins at a rating of 1500 — Gold I — with a wide-open uncertainty band. That uncertainty is what lets a new player's rating move quickly at first: your first several matches teach the system where you actually belong, then movement settles down as you play more.
A win against a higher-rated opponent moves your rating up more than beating someone below you — and a loss to a lower-rated opponent costs more than a loss to someone stronger. Rating changes reflect how surprising the result was, not just whether you won.
Winning big moves your rating a bit more than a narrow win, but the effect is capped. One lopsided blowout can't swing a season, and the closest possible win still counts as a real one.
A doubles result is scored using the two partners' combined average rating — a win or loss moves both partners by the same amount. But each player's own consistency narrows based on their own match history, so pairing with a brand-new partner doesn't suddenly make an established player's rating swing wildly.
Each tier spans 50 rating points. A fresh player at 1500 lands in Gold I.
