■ What is flash anzan?
Flash anzan is a "soroban-style" (Japanese abacus) way to do mental math: numbers flash on the screen one after another, and you add them up in your head. No abacus experience needed — start at the beginner level and work your way up.
■ Who it's for
• Kids and students who want faster arithmetic
• Soroban / abacus learners practicing for tests
• Adults who want a quick daily brain workout
• Anyone looking for a habit they can actually keep
■ Certification-based ranks
Question count, number of digits, and flash speed are designed around flash anzan certification standards. Begin at the entry grades, pass a promotion exam, and your rank goes up — from your first dan all the way to 20th dan. Your skill is shown clearly as a real rank.
■ See your progress
• High score and daily scores tracked in charts
• Switch between weekly, monthly, and all-time trends
• A practice calendar makes your run visible
■ Stay motivated
• Online ranking: compete with players worldwide, by week or all-time
• Daily missions: see today's goals at a glance
• Reminders: a gentle nudge at your practice time
■ Make it yours
• "Practice" mode: pick your own level (digits, count, speed) with no pressure
• "Challenge" mode: race the clock and test your limit
• Toggle read-aloud and sound effects
A few minutes of flash anzan a day turns calculation practice into a habit. Why not start with one round today?
