## What is Clean Sudoku?

Clean Sudoku is the classic number puzzle, rebuilt from the ground up: a calm board with no ads, and hints that teach you how to solve instead of just filling in a number.

DAILY PUZZLE
• A new puzzle every day, the same for everyone
• Keep your streak going and follow it from a Home or Lock Screen widget

SCAN OR SOLVE ANY SUDOKU
• Photograph a puzzle from a book or newspaper, or pick one from your photos
• Fix any digit the scanner misread, then play it or see the solution at once
• Type in a puzzle yourself, or open one a friend shared

HINTS THAT TEACH
• Every hint names the technique and shows why the move works
• Lessons for 23 techniques, from Hidden Singles to X-Wings and chains, each with an example on a real board

FIVE LEVELS
• Easy, Medium and Hard, plus Expert and Master with Clean Sudoku Pro
• Every puzzle has exactly one solution and is graded by the techniques it needs

FOR IPHONE, IPAD AND MAC
• Notes, automatic notes, undo and mistake highlighting
• Write digits with Apple Pencil, or play with a keyboard
• A Live Activity keeps your game on the Lock Screen
• Game Center leaderboards and achievements, plus detailed statistics
• Plays offline and saves your game automatically
• Available in 9 languages

CLEAN SUDOKU PRO
Pro unlocks Expert and Master puzzles, every lesson, the Paper and Glass styles and custom colors. Choose a yearly plan with a one-week free trial, a monthly plan, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your App Store account settings. If you played Clean Sudoku before version 2, Pro is free for you.
