What is Blue White Flag?

Identifying Fake Commands - The Game's Core!
It's not just following commands, but a judgment game.
Examples:
- "Don't raise blue flag, raise white flag!"
- "Except blue flag, raise white flag!"

- Peaceful - Slow pace, good for beginners learning rules
- Normal - Speed increases and fake commands increase
- Hard - Requires quick judgment and concentration

Practical Strategy Tips
Strategies for Beginners
Focus on Visual Signals First
Initially focus on visual signals rather than sound. Words and input boxes appearing on screen are highlighted to the beat, so watching these first is good. As you get used to it, you can gradually process sound and visuals simultaneously.
💡 Tip: Focus on accuracy over speed initially
Fix Hand Position on Arrow Keys in Advance
Fix hand position on arrow keys in advance to reduce reaction time. On PC, keep fingers on ⬆️⬇️ arrow keys, and on mobile keep both thumbs ready on touch areas of the screen.
💡 Tip: Fixing hand position makes reaction speed 2x faster
Strategies for Intermediate Players
Listen Carefully for Negative Expressions in Fake Commands
'Fake commands' are all about listening carefully for negative expressions in sentences. In "Don't raise blue flag, raise white flag", missing 'don't' causes mistakes. Pay special attention when negative expressions like "except", "excluding" appear.
💡 Tip: When you hear negative expressions, pause 0.2 seconds and react carefully
Learn Rhythm Sense
Through repeated learning, mastering rhythm sense makes even high-difficulty modes clearable. As you become familiar with the game's rhythm and patterns, your hands will move automatically. 5-10 repeated plays naturally adapts you to command types and timing.
💡 Tip: Consistent daily practice, even briefly, greatly improves skills
Strategies for Experts
Overcome Speed Birth Mode
The quite challenging 2 Speed Birth Modes are extreme challenges for experts. To clear this mode, you must completely familiarize patterns into your body through dozens of repeated practices. With almost no time to think, you must rely on unconscious reflexes.
⭐ Key: Form muscle memory through repeated practice - play speed mode by instinct
Warmup with Peaceful Mode
Warmup with Peaceful mode before serious play. Difficulty rises in order: Peaceful → Normal → Hard → Hell, and practicing in early modes reduces mistakes when entering high difficulty.
⭐ Key: Always start with easy difficulty to warm up your body
Practice Daily in Short Sessions
Consistent daily practice of 10-15 minutes is more effective than one long session. Rest when fatigued as skills decrease, so practice with appropriate rest.
