## What is 許爸的數獨?

許爸的數獨 is a 9×9 Sudoku game you can open anytime and enjoy at your own pace. We want everyone who loves Sudoku to play easily, without pressure or cost. The game is completely free, with no ads or paid features. Puzzles are generated on your device, and you can play without an internet connection or account.

New Solving Techniques lessons use step-by-step diagrams, example grids, and pattern cards to help you learn Sudoku reasoning from beginner to advanced levels.

Choose the way you like to play:

• Five difficulty levels, from Easy to Master.
• Relaxed and Challenge modes; Challenge mode limits mistakes.
• A daily puzzle based on your device's local date, with separate progress for regular and daily games.

Use notes, clear entries, undo moves and hints as you solve. Pick up where you left off later. Your completed puzzle count and best time for each difficulty are saved on your device.

Share a puzzle with a friend: send the original puzzle to start together, or include your current board, notes, time, hints used and mistakes so a friend can continue. Paste a friend's puzzle message on the home screen to preview and import it. Friend puzzles keep their own progress, separate from regular games and daily challenges.

Choose color mode or enable Older device compatibility mode to reduce resource use on older devices or when play feels slow. Switch between Traditional Chinese, English and Japanese. To keep or move your progress, export a backup through your device's share menu and import it from a file later.

Whether you solve one puzzle a day or work toward a harder level, you can enjoy Sudoku wherever you are.
