cn anyone plz tell what is most karma because my game is no1 in it for some reason and btw plz rate my game plz 

I have no idea. If I had to guess, I would say that you probably rated a lot of games or something.

It is pretty much average rating times number of ratings.

There's a 2019 thread on it:  https://itch.io/t/527869/karma-system-for-the-game-jams
