Move the soroban's beads with your finger to build numbers and get a real feel for calculation. SOROBAN Drag the beads on the on-screen abacus and the current number shows large as you go. Full-featured: you can even choose which column is the ones place (fixed-point marker). Clear, undo, and toggle the result display — use it as freely as a calculator. PRACTICE Pick a grade (10 kyu, easiest, through 1 kyu, hardest) and a type — addition & subtraction, multiplication, or division — then solve 10 questions. The abacus board stays on screen, so you can move real beads while you work. Each answer is checked the moment you enter it, with a full score at the end. RECORDS Every practice run is saved automatically — date, grade, type, and number correct. A perfect score gets its own special mark. Seeing your progress makes it easier to keep going.
