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.
• Finish a puzzle and the grid says so — a wave of teal across the board, then confetti. Tap once to skip it if you’d rather start the next one.
• Stats tracked locally. No account required, works fully offline.

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