The way this jam works (other jams can work in other ways) is that the ratings that we are all giving will result in the games getting ranked under each category. The system will automatically calculate it when the rating period is over, which is in 10 days. So there will be a "winner" for each category (and possibly an "overall" category/calculation too) but there isn't a group of judges, or anything, playing through each game manually and deciding on a winner.
