Sudoku - Classic Sudoku Puzzle

This is a solo, portrait-oriented Sudoku puzzle game with standard progression and high replay value, suitable for players seeking a relaxing mental challenge. While playable offline and with optional sound, be prepared for frequent, unskippable ads that can interrupt gameplay, though the core puzzle experience is short and can be played one-handed. It's best for players who can tolerate aggressive ad monetization for a classic puzzle experience.
