Ranked play, rating, and rank (dan)

How your rating moves and how rank (dan) is decided.

Do I need to register for ranked play?

Yes. Registration is free, and playing is free.

How does my rating change?

It moves when you play someone with a close rating. Beating a stronger opponent gains you more; losing to a weaker opponent costs you more.

How is rank (dan) decided?

It is based on your rating range. You are promoted after exceeding the upper bound of your current rank in 3 games in a row. These numbers may be adjusted as we go.

How long is a season?

3 months. Rank is finalized at the end, and part of your rating carries over.

What happens on a draw?

For games that allow a draw, ratings do not change.
