Points

Oh, it's just because of your Glicko RD.

In simple terms, your Glicko RD tells you how accurate (or how approximate) your current rating is. An RD of 20 indicates that your rating is correct within 20 points plus or minus, while an RD of 150 indicates a much looser approximation... plus or minus 150 points.

So your Daily rating of 1334 RD 205 means that your rating is only approximate, and that your true playing strength might be anywhere between 1129 and 1539.

The more often you play, the more accurate your rating will be and the lower your RD will drop. And vice-versa: the more seldom you play, the less accurate your rating will be and the higher your RD will climb.

Oh

Thank you @Abhinav0121 :D

you also get more points if you beat someone notably higher than you, and less if they are weaker than you.
