🧐 Frequently Asked Questions
Q. What are "Green Number" and "White Number"?
A. These terms originate from Konami's BEMANI series, particularly beatmania IIDX. The "Green Number" represents the effective scroll speed—how long a note is visible on screen. The "White Number" is a value related to the lane cover setting, which determines how much of the top of the lane is hidden. This calculator uses the standard community-derived formula: White Number = 1000 - (Green Number * BPM * Hi-Speed) / 174.
Q. What is a good "Green Number" to aim for?
A. This is highly subjective and depends on personal preference, play style, and monitor size. Many players find a value between 280 and 320 to be a comfortable starting point. The key is to find a speed that allows you to read patterns clearly and then use this calculator to maintain that same speed across all songs.
📚 Fun Facts about Rhythm Game Scroll Speed
The concept of maintaining a fixed scroll speed, represented by the "Green Number," is a cornerstone of high-level play in many modern rhythm games. In early games, scroll speeds were often tied directly to a song's BPM, forcing players to constantly readjust their reading for fast or slow tracks.
The introduction of detailed Hi-Speed modifiers and systems like the "Green Number" revolutionized gameplay. It allows players to develop consistent timing and pattern recognition skills by ensuring the notes always approach at the same visual velocity, regardless of the song's tempo. By "locking in" their preferred visual speed, players can focus their mental energy on execution and mastering complex charts, making it an essential technique for serious improvement.
