The Perfect mod is a game modifier that aims to aid players who are going for an SS grade by automatically failing and retrying beatmaps if the player misses a note or obtains any judgement on a hit object other than GREAT.

Any of the following acts will cause the Perfect mod to restart the beatmap:

  • Missing a note
  • Obtaining a OK or MEH
  • Failing a spinner
  • Dropping a slider's tail or doing a slider break

Any of the following acts will not cause the Perfect mod to restart the beatmap:

  • Obtaining a GREAT
  • Completing a spinner
  • Obtaining a PERFECT (osu!mania)
  • Obtaining a MEH/OK/GOOD on the head/tail of a long note in ScoreV2 (osu!mania)

This mod has the same effect across all game modes.


  • If there is a skippable prologue, the Perfect mod will not automatically skip it, because it uses restart functionality, as opposed to a quick retry.
