Frequently Asked Questions
How do I scan a Sudoku puzzle?
Open the app and tap the "Scan" button on the home screen. Point your camera at a Sudoku puzzle from a newspaper, book, or screen. The OCR scanner will recognize the puzzle and let you play it instantly.
What is Kidz Mode?
Kidz Mode is a child-friendly version of the game with simpler 4x4 and 6x6 grids, playful colors, and no time pressure. It's perfect for children learning Sudoku or anyone who wants a more relaxed experience.
How does streak tracking work?
Complete a puzzle each day to build your streak. The streak counter increases each consecutive day you solve a puzzle. Missing a day resets your streak to zero.
Can I see my puzzle statistics?
Yes! Navigate to the Stats tab to see your puzzle history, best times by difficulty, completion rates, and overall progression. All stats are stored locally on your device.
Is my data safe?
Absolutely. Zen Sudoku stores all your game data locally on your device. We don't collect, transmit, or store any personal information. See our Privacy Policy for details.
