Nintendo will be checking Super Mario Maker courses to determine difficulty level

Courses uploaded by the community in Super Mario Maker will feature different difficulty labels. For the most part, this is chosen dynamically as more players try out the level. As an example, if a course has only been completed 10 times out of 150 attempts, you’ll probably notice that it’s in the hard category.

This isn’t the only way that a course in Super Mario Maker will earn its difficulty label. Engadget reports, “user-created levels are also vetted by Nintendo moderators to determine level difficulty before it’s available for anyone to download.”
