To achieve the top score in a song you need to get all 'Perfect+' beats AND hold all the hold beats until the end.
Get Perfect+ by tapping exactly at the time the beat overlaps with the perfect bar area. If you’re a little early/late it registers as perfect only.
The multiplier is streak-based. When you break a streak, the multiplier goes down by 1 level each time.
The cap on the multiplier varies by song difficulty:
• On Extreme songs, the max streak is x5
• On Hard songs, the max streak is x4
• On Normal songs, the max streak is x3
The max streak is higher for higher difficulty songs because there are more beats.
