Rating System

The rating system measures your competitive skill in Dominion rounds. It is based on Glicko-2, a proven chess-style rating algorithm that tracks not only how strong you are, but also how certain the system is about that estimate.

How the rating works

Every player has an internal skill rating, starting at 1500. After each Dominion round, the rating moves up or down depending on your placement and the strength of your opponents: beating stronger opponents gains more rating than beating weaker ones.

Alongside the rating, the system tracks a rating deviation (RD) — a measure of uncertainty. New or inactive players have a high deviation (starting at 350); the more you play, the smaller it gets and the more precisely the system knows your skill. Long inactivity slowly increases the deviation again.

Displayed MMR

The MMR you see in rankings is a conservative estimate: the internal rating minus 2.5 times the rating deviation. This means new players start with a low visible MMR and earn their way up by playing — you can't luck your way to the top with a handful of games. As your deviation shrinks, your visible MMR climbs towards your true rating.

Reliability

Rankings show a reliability indicator derived from the rating deviation, so you can tell how settled a player's rating is:

Reliability	Meaning
High	Rating deviation of at most 80 — the rating is well established.
Medium	Rating deviation of at most 160 — a solid estimate, still moving.
Low	Higher deviation — few recent games, the rating can still swing a lot.

The rating is about skill and is separate from the ranking system, which measures long-term progression activity in Ove.
