Dadu the Great Soroban sneezed, and every bead bounced away across Gutiland. Help Moyna the myna bird bring them home through six places: Pebble Pond, Mango Grove, Rice Fields, River Boats, Train Station and The Fair. On the way, children learn to show and read numbers on a soroban abacus, add and take away, and picture the beads in their mind. Made by Kidosia. No ads, no accounts, and it works offline.
