Ratings:

Along the divisions, you have an overall rating, which shows how well you have performed and how skillful you are on a more granular level. The amount of overall rating points you gain or lose in each game depends on your opponent's overall rating. Active players in the Gold division and above can see the overall rating in their profile and in the Solo Duels page. The overall rating of Silver and Bronze division players is hidden.
In addition to the overall rating, which takes all game modes into account, you'll be able to see your game mode (Moving, No Move, NMPZ) specific ratings once you're in Gold division or above, and have played a certain number of games to unlock them. Note that the game mode specific ratings are not used for matchmaking or promotion/demotion between divisions - these are purely for statistical purposes.
