Flash Anzan - Soroban Math

40 levels on the Japanese soroban standards. Every level states its spec: digits, terms and timing. No ads while you are solving.

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.
