Sudoku EyeCare

Classic Sudoku with a calmer, clearer interface. Eye-care themes, night mode, larger text, and break reminders — designed to feel comfortable every session.

Sudoku EyeCare is not just a complete classic Sudoku app. It is built around a simple idea: solving puzzles should still feel comfortable during longer sessions.

Play standard 9x9 Sudoku with flexible difficulty levels, multiple input styles, notes, undo and redo, hints, daily challenges, and personal stats. Beginners can rely on layered hints and learning support, while experienced players can enjoy a stable puzzle library and a focused solving flow.

What makes the app different is its eye-comfort experience for night play, low-light environments, and extended sessions:

• Eye-care themes and a dark night theme
• Automatic night mode based on system settings or a custom time range
• Larger text, more readable candidate numbers, and bigger touch targets
• Softer highlights, gentler animations, lighter error feedback, and optional reduced vibration
• Focus mode to reduce visual noise around the board
• Lightweight 20-20-20 inspired eye break reminders
• Quick 15-30 second break pages that help users pause without losing progress
• Presets tailored for night comfort, long sessions, readability, and older users

Sudoku EyeCare is designed to be easy to start, rewarding to grow with, and comfortable enough to come back to every day.
