Mental Math vs EbiOboe

■ 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.
