About this game

Solve number grids at your own pace with a calm, focused logic experience.

Work through 6 × 6 beginner puzzles or 9 × 9 standard grids. Every row, column, and region must contain each number without repeats. Original clues stay protected while your entries, candidates, conflicts, and deductions remain easy to distinguish.

Choose a chapter, continue an unfinished puzzle, or take a locally selected daily challenge. Candidate mode lets you record possibilities without treating them as answers. When you need direction, up to three hints explain a checkable deduction instead of simply revealing a solution. Undo and reset support careful experimentation.

Review your completed puzzles and build a personal local record over time. Preferences include light and dark themes, conflict markers, gentle motion, and assistance display.

The entire experience works offline. Your progress and preferences stay in private storage on your device. There are no accounts, ads, social features, or leaderboards.
