• Import puzzles from your photo library
• Correct recognition results manually
• Step-by-step logical hints
• Learn advanced solving techniques
• Save puzzles and continue anytime
• Clean and easy-to-use interface
• Supports both beginners and experts

Instead of giving you the solution, Sudoku Tutor teaches you how to think.
