-===Rating===+===Editor'Rating===
 Each map has a fixed rating on the description page. Unlike the user rating further down, this one is given by the Quaddicted staff. The purpose is to give players an indication of the quality of the map and whether it might be worth playing or not. Of course it is not the final word, and in some cases may even be quite questionable, but the main idea was to approach it in a somewhat objective way by taking a variety of factors into account, such as release date, technical aspects, and creativity. As of now, there are five text ratings that roughly correspond to school grades. Each map has a fixed rating on the description page.

 +===Users' Rating===
 +The users' rating on https://www.quaddicted.com/reviews/ is not a plain average value but a Bayesian average. This means that outliers are given less weight, for example if there are 10 votes with a rating of 5 and 1 rating with a value of 1.
