Just Sudoku

Classic sudoku on Android, built without the noise. No ads interrupting your solve, no tracking, and no locked features. Everything is there from the first install. No premium tier, no “pro” mode, no nudges to upgrade. The stuff other apps charge for is just… included.

• Three difficulty levels, all included from the start.
• Pencil notes with automatic candidate clearing.
• Unlimited undo.
• Light and dark themes, follows system preference.
• Stats tracked locally. No account required, works fully offline.

The name is the whole description. Just the grid. Just the puzzle.
