Rank

In all games in the Rhythm Heaven Series, the player is given a Rank (ランク) depending on their performance in a Rhythm Game.

Description
When the player first starts a new file and reaches the Game Select, they are presented with only one Rhythm Game to play. Upon finishing it, their performance is rated based on specific categories (depending on the game), with each carrying a comment. Depending on this, the player may receive the following Ranks:

Try Again
If the player did poorly, they receive the Try Again (やりなおし) rank. The Rhythm Game does not get cleared if this is achieved. In Rhythm Heaven and Rhythm Heaven Megamix, the uncleared Rhythm Game has a white border around it.

OK
If the player did good enough, they receive the OK (平凡) rank. The Rhythm Game is cleared if this is achieved, unlocking the next game. In Rhythm Heaven and Rhythm Heaven Megamix, this rank also puts a silver border around the Rhythm Game.

Superb
If the player played really well, they receive the Superb (ハイレベル) rank. The Rhythm Game is cleared, the player is given a Medal, and the game is eligible for a Perfect Campaign. In Rhythm Heaven and Rhythm Heaven Megamix, this rank also puts a gold border around the Rhythm Game. In Rhythm Tengoku, Rhythm Heaven Fever and Rhythm Heaven Megamix, a medal icon is also shown. In Rhythm Heaven Megamix, getting a Superb on all Rhythm Games is commemorated with a Badge.

Perfect
If the player manages to finish a Rhythm Game without missing once during the Perfect Campaign, they receive the Perfect (パーフェクト) rank. The player receives a gift for their achievement. In Rhythm Tengoku, this rank is denoted with a pink heart with the letter "P" inside of it, separate of the Superb rank. In Rhythm Heaven, this instead replaces the Superb rank, denoted with a gold border with the word "PERFECT" on it. In Rhythm Heaven Fever, this is denoted with a new medal with a "P" on it, and in Rhythm Heaven Megamix, the "P" Medal is used, along with a platinum border. In Rhythm Heaven Megamix, getting a Perfect on all Rhythm Games is commemorated with a Badge.

Miscellaneous Information
In Rhythm Heaven Megamix, the ranks work in a slightly different manner. Each rank is tied to a certain score, with 0 to 59 points giving Try Again, 60 to 79 being OK, and 80 to 100 being Superb. Each rank also gives a varying amount of Coins.

If the player gets a Try Again, but does well enough in one category to trigger a Superb comment on it, they are given a blurb saying they did well, encouraging them to keep trying. In Rhythm Heaven Megamix, this may happen if the player got 55 through 59 points, in which case the "good parts" are acknowledged, and the player is given 5 points to roll over to OK. Simply getting 55 through 59 points does not guarantee this will happen, however.

If the player gets a positive comment, but did not do well enough for Superb, they receive an OK. Notably, this version of the rank has the message "Just OK" (Rhythm Heaven), "...but still just... OK" (Rhythm Heaven Fever), or "but, just... OK" (Rhythm Heaven Megamix).

In Rhythm Tengoku (Arcade)
Due to the arcade setting, the ranks are reworked in Rhythm Tengoku (Arcade). When the player begins a Stage, they are given three hearts representing how many tries they get. Beginning a Rhythm Game deducts one heart, and losing them all prompts the player to add credits to continue, or else they are returned to the menu. Getting a Superb rank rewards one heart, and locks the game for the rest of the Stage. The Perfect Campaign is no longer present, however the player can achieve a Perfect rank as if in a campaign. Aside from the visuals however, it works the same as a Superb. The ranks work the same way otherwise.

Trivia

 * If the player gets a Try Again three times in a row on an uncleared game, the Barista at the Café offers to help the player by skipping it, which if accepted, gives an OK rank for that game. In Rhythm Heaven Fever, the Barista also gives the player the option to watch a Demo Video, which shows what the Rhythm Game in question would be like if played perfectly. In Rhythm Heaven Megamix, however, Rupert instead charges the player a certain amount of Coins to skip.
 * While each game has negative comments for Try Again and positive comments for Superb, there is only a selection of generic comments for OK.
 * This feature is also referred to as the "rating" in one instance, though it should be noted this same instance also erroneously calls the Superb rank a "High Level rating", and the Perfect Campaign the "Perfect challenge".
