Designed around your attention
Everything a Sudoku needs. Nothing it doesn't.
Helpful, never noisy
Notes, undo, erasing, and measured hints stay close when you need them—and disappear when you do not.
Private by design
No account, no advertising, no analytics, and no tracking. Your puzzle is saved only on your device.
The rules, in one breath
One of each number. In every direction.
Fill each row, column, and 3×3 box with the numbers 1 through 9. No repeats. Every complete row, column, and box also adds up to 45—but logic, not arithmetic, reveals the answer.
