Playing Kudoku
Fill each row, column and 3×3 box with 1–9. Numbers in a cage must add up to its target without repeating. The interactive tutorial explains both rules.
25,000 puzzles span five difficulties. Play each track in order for free, enjoy daily challenges, collect badges, or try Hell mode. The game has no ads and needs no account. Puzzles work offline.
Premium and purchases
Optional Premium adds unlimited hints, Auto Notes, note highlights, last-cell hints, detailed statistics, themes, direct access to every catalog level, unlimited mistakes in regular levels and iCloud progress sync. Free play includes three hints a day. Hell mode retains its own run rules.
