How to play
• Choose Ion mode or Ionic compound mode
• Tap the correct formula as fast as you can
• Targets all look the same — you only find out after you shoot

Hard mode
• Ions → same ion, wrong charge/sign
• Compounds → wrong ratios (salts) or near‑miss acids

Boss rounds
• Every 10 correct answers triggers a boss round (more targets)

Scoring
• Correct: +10 (Boss: +45)
• Wrong: −6 (Boss: −10)
