Difficulty naming

The purpose of difficulty naming is to inform players how difficult a map is. This article lists common conventions as well as other alternatives that have been gathered throughout the years. However, as long as the set of difficulty names is descriptive and clearly indicates progression of difficulty, you may use any desired kind of scheme.

Default

These difficulty names are the most commonly used for each game mode.

Note: The special difficulty name Marathon historically allowed mappers to submit maps of longer songs, and thus became popular for single-difficulty mapsets. Today, the name has no special meaning and is typically only used for very long songs or song compilations.
