Lantern Sudoku 퍼즐 앱 대상 Android 설명
Lantern Sudoku is a quiet sudoku for short, calm sessions. It has no ads, no account and no game over, and it works fully offline.
When you're stuck, a hint lights the next step instead of giving the answer away. You choose how much help you want:
- Where to look: the area where the next step is.
- Why: the technique by name, with a short explanation and the cells that matter highlighted.
- The digit, only if you want it.
If a digit on the board is wrong, the hint tells you that first, so you never chase a step built on a mistake.
Honest puzzles
- Four levels: Easy, Medium, Hard and Expert.
- Every puzzle has exactly one solution and never needs guessing.
- Each puzzle is graded by the hardest technique it needs, so a level means the same thing every time.
- More than 11,000 puzzles come with the app. Nothing is downloaded.
A daily puzzle
- One puzzle a day, the same for everyone, with a streak and days played.
- Share a spoiler-free result card if you like. Nothing is shared unless you tap Share.
Made to be easy on the eyes
- Large, clear digits, with a Larger digits option.
- Light, Dark and two high-contrast themes.
- Works with large system text and with TalkBack.
Never punished
- Mistakes can be shown or hidden. A mistake limit is optional and off by default.
- Your game is saved after every move. Undo, redo, erase and notes that tidy themselves when you place a digit.
- A calm summary when you finish, and statistics per level.
Private by design
- No ads, no analytics, no crash reporting, no account.
- The app asks for no permissions, not even internet access.
- Your games stay on your phone. If Android backup is on, Android may copy them to your own Google account; the app itself never uploads anything.
Lantern Sudoku is free and open source software (GPL-3.0-or-later).
