## What is Sudoku Classic Master?

Sudoku the way it should be: clean, fast and relaxing. Whether you have five minutes or an hour, Classic Sudoku gives you the perfect number puzzle — no clutter, no login, just you and the grid.

TRAIN YOUR BRAIN, YOUR WAY
Choose from four carefully balanced difficulty levels — Easy, Medium, Hard and Extreme. Every single puzzle is guaranteed to have exactly one solution, so you can always solve it with logic alone.

A NEW CHALLENGE EVERY DAY
Come back daily for the Daily Challenge and build your streak. Miss a day? Keep your streak alive with a Streak Freeze. Watch your progress fill up in the monthly calendar and chase your longest run yet.

SMART HINTS THAT ACTUALLY TEACH
Stuck? The built-in hint doesn't just fill a cell — it explains the logic behind the move (Naked Single, Hidden Single and more), so you get better every time you play.

EVERYTHING YOU EXPECT — DONE RIGHT
• Pencil notes for tracking candidates
• Unlimited undo
• Automatic mistake highlighting with a 3-lives mode
• Smart number pad that shows how many of each digit are left
• Row, column, box and matching-number highlighting
• Timer, statistics and personal best times
• Auto-save — pick up exactly where you left off

BEAUTIFUL IN LIGHT & DARK
A calm, modern design that looks great day or night and automatically matches your system appearance.

PLAY YOUR WAY
Sudoku is free to play. Prefer zero interruptions? A one-time Remove Ads purchase clears all advertising and unlocks extra options like turning off the mistake limit.
