Numbers flash for an instant, then vanish. Add them in your head. Flash anzan practice built on the Japanese soroban grading standards — useful whichever abacus programme you study under. 40 LEVELS Level 1 to Level 40. Every level states exactly what it is: 2 digits × 5 terms · 8s, and so on. Digits, terms and timing come from the official Japanese grading standards, so the ladder is real rather than invented. Get 7 of 10 to pass, 5 or 6 for a near pass. PRACTICE — your own settings 1 to 5 digits, 2 to 30 terms, 0.05 to 5.0 seconds per term. The slow end really does go to 5 seconds, so beginners fit too. Subtraction and comma separators are optional. ONE-MINUTE DRILL How many can you answer in 60 seconds? Addition, subtraction, multiplication and division. Just tap the answer. HOW TO Four short lessons on what abacus classrooms actually teach: why words are too slow, the pairs that make 5 and 10, how to move the abacus into your head, and what to raise in what order. BREAD COUNT — a break Count loaves instead of digits. 20 stages, 24 kinds of bread to collect. DIGITS THAT LOOK RIGHT The numbers use the handwritten forms taught in abacus classrooms, not a generic typeface. If you have studied soroban, they will look familiar. ADS No ads at all while a problem is on screen. They appear only between sessions, limited by both count and time. IN-APP PURCHASE A one-time purchase removes the ads. Pay once; nothing renews. Use "Restore purchase" when you change devices. Every mode stays free. Problems are never behind a paywall. RECORDS Every answer is written to the device immediately, so a crash never loses your progress. Privacy Policy https://tomople.com/privacy-policy/
