Yes, I imagine it wouldn't depend ONLY on the number of ratings, but I'm curious if that plays a role at all, or just rounds the "score" more accurately. I'm new to this :)
In general, as far as I know, in some jams there is a jury in addition to the players, and the game can take some place according to the players and some according to the jury. But this is only in some jams, in this one there is most likely no jury
