About this app

Find your next move, one clear deduction at a time. Enjoy classic 9×9 Sudoku with a clean board, pencil notes, and hints that help you understand the reasoning. Start with the basics or settle into a harder puzzle at your own pace. • Four difficulty levels, from Beginner to Expert. • Daily challenges with a completion calendar and streak tracking. • An optional hands-on tutorial for entering numbers, taking notes, and using logical hints. • Logical hints with explanations and board highlights for single-candidate and single-position deductions. • Notes, undo, erase, and highlighting for rows, columns, boxes, and matching numbers. • Training levels and a replay of your moves after completing a puzzle. • Statistics, daily goals, and badges to record your progress. • Six themes, with sound, haptics, and optional daily reminders. No account registration is required. Game progress is saved on your device. The app includes ads and an optional in-app purchase to remove them. When hint credits run out, you can choose to watch a rewarded ad for more hints. Take a moment. Solve a puzzle.

Try the optional tutorial to practice number entry, pencil notes, and logical hints. Logical hints now include explanations and board highlights. Incorrect entries and positions without a supported deduction are explained without using a hint credit.
