Store description excerpt
Sansū: Origami Numbers is a warm, hand-folded take on the classic arithmetic grid puzzle — the kind created to make practicing math genuinely fun. Fill the grid so that every row and every column uses each number exactly once, with no repeats. Each outlined "cage" shows a target and a sign (＋ − × ÷); the numbers inside must combine to hit it. It's part Sudoku-style logic, part mental arithmetic — and every puzzle has exactly one solution you can reach by reasoning, never guessing. THREE WAYS TO PLAY • Solo — an endless supply of fresh puzzles at your own pace, with pencil notes, undo, and a gentle hint. • 2 Players — pass-and-play on one device: same puzzle, fastest correct solve wins the round, best of three. • vs Computer — race a friendly, beatable opponent whose speed scales with the difficulty. MADE FOR EVERY AGE • Easy (adding only), Medium, and Hard grow with the player — from first sums to all four operations. • A "Coach" mode highlights repeats and offers a nudge when you're stuck. • Big, tappable number keys made for small hands. THOUGHTFULLY BUILT • 11 languages, with full right-to-left support for Arabic and Urdu. • 100% offline — no internet, no accounts, no ads, and no data collection, ever. • One simple, one-time purchase. Yours forever. A quiet, beautiful way for kids and grown-ups alike to fall in love with numbers.
