Rating

Learn how the map rating works, this can come in handy to make mapsets or just to get a general sense of difficulty

WARNING

It is recommended to check out the following articles before reading:

• Quantum usage
• Patterns
• Skillsets

Common terms

• Overmap: A map which includes more notes than it should. Typically presented with high divisor usage.
• Undermap: A map which includes fewer notes than it should. Notes are often omitted and emphasis is lowered too.

Considerations

• When talking about BPM limits:
• • Flicks/Jumps are considered to be mapped in 1/2 divisor with the stated BPM.
• • Streams/Spirals are considered to be mapped in 1/4 divisor with the stated BPM.
• • The actual limit may fluctuate due to pattern difficulty and readability.
• Quantum patterns should resemble the behaviour (speed and movement) of certain regular patterns.

Difficulty Ratings

In the game, there are 5 difficulties, which come with their own patterns and restrictions:

• Easy:

  • Only 3x3 ongrid patterns are allowed.
  • No real BPM limit, but keep the difficulty lower than Medium.

• Medium:

  • Maps can have Quantum patterns, preferably as low-divisor Bézier curves at most. Offgrid is forbidden.
  • No real BPM limit, but keep the difficulty harder than Easy.

• Hard:

  • Maps can have any sort of Quantum patterns, as long as the difficulty stays consistently under LOGIC?. Offgrid is forbidden.
  • Minor skillset usage allowed, as long as the map's difficulty fits.
  • BPM should be between 175 and 250 (approx.)

• LOGIC?:

  • Maps can have any sort of Quantum patterns, including offgrid, as long as the difficulty stays consistently under BRRR.
  • Maps should focus on at least one skillset.
  • BPM should be between 250 and 350 (approx.)

• BRRR (SS) & Tasukete (SS+/Rhythia):

  • Maps can have any sort of Quantum patterns, but make the patterns clear at all times; avoid messy patterns.
  • Maps must focus on at least one skillset.
  • BPM should be higher than 350 (approx.).

You may take a look at some archived maps to see some examples.

Exceptions

There's also some exceptions to these rules worth noting, such as:

• If the map requires using a certain pattern for expression, the rules can be overridden to a certain extent.
• Undermapping is allowed and encouraged for any of the lower difficulties.
• Overmapping can be done on LOGIC?+ difficulties as long as it fits the song and to fit within the difficulty scaling.
