It has no ads, no account and no game over, and it works fully offline.\n\nWhen you're stuck, a hint lights the next step instead of giving the answer away. You choose how much help you want:\n• Where to look: the area where the next step is.\n• Why: the technique by name, with a short explanation and the cells that matter highlighted.\n• The digit, only if you want it.\nIf a digit on the board is wrong, the hint tells you that first, so you never chase a step built on a mistake.\n\nHonest puzzles\n• Four levels: Easy, Medium, Hard and Expert.\n• Every puzzle has exactly one solution and never needs guessing.\n• Each puzzle is graded by the hardest technique it needs, so a level means the same thing every time.\n• More than 11,000 puzzles come with the app. Nothing is downloaded.\n\nA daily puzzle\n• One puzzle a day, the same for everyone, with a streak and days played.\n• Share a spoiler-free result card if you like. Nothing is shared unless you tap Share.\n\nMade to be easy on the eyes\n• Large, clear digits, with a Larger digits option.\n• Light, Dark and two high-contrast themes.\n• Works with large system text and with TalkBack.\n\nNever punished\n• Mistakes can be shown or hidden. A mistake limit is optional and off by default.\n• Your game is saved after every move. Undo, redo, erase and notes that tidy themselves when you place a digit.\n• A calm summary when you finish, and statistics per level.\n\nPrivate by design\n• No ads, no analytics, no crash reporting, no account.\n• The app asks for no permissions, not even internet access.\n• 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.\n\nLantern Sudoku is free and open source software (GPL-3.0-or-later).\n","categories":["Puzzle Game"]}
