Skill rating
Rating
Your rating is a number that estimates your skill in a game, powered by Glicko-2 — the same system many competitive games use. You start at 1500 in every game, and the number moves only when you play a rated match against other humans.
What the number means
Higher is stronger: your rating is how the system estimates your skill against everyone else in that game. Ratings are kept separately per game, so your Chess rating and your Xeri rating move independently.
Starting point
Everyone begins at 1500 in each game. Beat players rated above you and your number climbs; lose to players rated below you and it slides.
Higher is stronger
The higher the number, the stronger the player. Glicko-2 keeps refining its estimate of your skill as your results come in.
Peak
Your peak is the highest rating you have reached in that game — a permanent high-water mark, even after your current rating dips.
One per game
Xeri, Agonia, Tavli, Checkers and Chess each carry their own rating, peak and history. One never affects another.
How it updates
Only the outcome matters, weighed against who you played. Beating stronger players raises your rating more than beating weaker ones; losing to weaker players costs more than losing to stronger ones. A tie leaves the number unchanged, and the biggest swings come early on.
Certainty grows with play
Glicko-2 also tracks how sure it is about your skill — its rating deviation, or RD. New players carry a wide RD, so early results move them further; as you play more rated matches the RD shrinks and the number settles.
Rated matches
A rated unit is a finished match between humans: a whole Xeri game, an Agonia match, a whole Tavli match, or a full game of Chess or Checkers. Conceding settles normally.
Unrated matches
Bots and system seats are never rated. A match is also unrated when it lasts under 30 seconds, when Xeri sees fewer than eight human plays, or when a pair has already played eight rated matches against each other in 24 hours. Unrated games still count as games — they just do not move your rating.
Placement
Your first 5 rated matches in each game count as placement. Results still settle your rating normally, while the arena boosts pots and forgives losses — a soft landing while your number finds its level.
Where you see it
Your profile Statistics section shows your current rating, peak and rating history for every game. On rated tables your rating helps shape the pot odds, so beating a favourite pays more.
