A Superb (also called a High-level) is a rank achieved on Rhythm Games in the Rhythm Heaven series, depicting that the player did an excellent job on a minigame. Obtaining this rank will earn the player a Medal, which is used to unlock various features, such as Rhythm Toys.
The player earns a Superb when they recieve two or three (depending on the minigame) sets of praise comments. These appear after the player completes a minigame and vary from game to game. In general, few mistakes are allowed to unlock these comments.
Achieving this rank will earn the player a medal, along with the Rhythm Game obtaining a gold frame. In addition, the game becomes eligible for a Perfect challenge, which will randomly appear on any game with a Superb rating.
