Abacus Legend

The abacus is not an ancestor of the calculator. It is a way of thinking that lives in your hands. Abacus Legend puts a real 2:5 suanpan on your screen. Each bead above the beam counts five, each below counts one, and a bead pushed toward the beam is active. Tapping feels like the real thing: tap an active bead and it slides away together with everything between it and the beam; tap an inactive one and it comes in the same way. A rod may even read 15 for a moment, because that is exactly how a real abacus passes through a carry. NINE CHAPTERS, NINETY STAGES, NINE KINDS OF PROBLEM From reading your first bead all the way to division: · Set — dial the given number · Addition — make five, carry ten · Subtraction — break five, borrow ten · Chain — several operations in a row · Flash — numbers appear one by one; add each to the abacus as it comes. The abacus is your memory, and everything shown stays on screen · Deft — reach the target within a strict budget of bead moves · Complement — what completes it to ten, hundred or thousand: the backbone of bead arithmetic · Multiplication — single-digit multiplier, rod by rod · Division — exact division; estimate, then place DAILY CHALLENGE Ten questions a day, identical for every player, drawn from all nine chapters. Your best score and your streak are kept. ALWAYS SOMETHING TO WORK ON Fourteen achievements, eight upgrades (more time, hints, a shield, combo bonuses, softer penalties) and six abacus skins: sandalwood, jade, blue porcelain, gold, inkstone and starlight.
