Cafe Sudoku - Classic Puzzle

A little coffee-break calm. One satisfying square at a time.

Cafe Sudoku brings classic 9×9 puzzles to your daily downtime. Solve with logic, not guesswork, and find your next step with hints that explain why. With no full-screen ads between games, you can stay focused on the puzzle.

☕ Five levels, from easygoing to expert
Easy · Medium · Hard · Expert · Master.
Difficulty is based on the solving techniques each puzzle requires—not the number of empty cells. Every puzzle can be solved by logic alone. Start wherever you feel comfortable, then take on a new challenge when you’re ready.

💡 Learn the why, not just the answer
Hints explain where to look, which technique to use, and why a number belongs in a cell. They help you move past a tricky spot while building skills you can use in your next puzzle.
Hints are unlimited for everyone. No ad-watching required.

📅 A daily puzzle. A collection to grow.
Everyone gets the same Today's Puzzle each day. Complete challenges on 20 days in a month to earn that month’s mug.
Build your mug collection and earn 43 achievement stickers for consistency, skill, and exploration.

🍰 One small banner. No interruptions between puzzles.
The only ad is a small banner at the bottom of the screen. There are no full-screen ads between games and no rewarded ads.

🎨 Your colors. Your way to play.
Set the mood with color themes named after café drinks, and settle into the solving style that suits you.
