Play others' maps.
In order to review other players' maps and join the track review server, you must navigate from the main menu to CREATE, then TRACK REVIEW, and finally REVIEW OTHER TRACKS. Once selecting REVIEW OTHER TRACKS, you will be able to select whether you want to review maps for TRACK OF THE DAY or ROYAL.
Once choosing a map review type, you will then be moved to a review server, where you will be able to test other players\' maps and give them a rating from 1-5 stars.
These ratings will be seen by map selectors from Ubisoft Nadeo and based on the amount of reviews, will decide whether the map is qualified to be either a Track of the Day, or a Royal Map.
