Mossgrid: Sudoku Offline Game

Mossgrid is classic sudoku on a calm board of moss and river stones, made for players who want to solve at their own pace. Fill every row, column and 3x3 box with the digits 1 to 9. There are no lives and no mistake limit, and it plays offline. NO LIVES, NO MISTAKE LIMIT A wrong digit never ends your game. Repeated digits glow red as you play, and Check rings every wrong digit whenever you ask. Your first check on each puzzle is free, and undo is always free. LOGIC, NEVER LUCK Every sudoku puzzle is checked by a solver that only makes forced moves, so it has exactly one solution and you never have to guess. EASY TO EXPERT Start with easy sudoku, then move through medium and hard sudoku to expert puzzles with fewer clues. A new Daily Stone puzzle arrives every day, the same for everyone. NO ADS WHILE YOU SOLVE Nothing ever pops up in the middle of a puzzle and there are no banners. A short ad can appear between puzzles now and then, never after every one. Videos for coins only play when you tap them, and pay out as soon as they finish. PLAYS LIKE PEN AND PAPER - Tap a cell and its row, column and box light up, along with every matching digit. - Pencil notes: turn on Notes to jot candidates. Placing a digit wipes it from the notes around it. - The number pad shows how many of each digit are left, and finished digits fade away. - Finished rows, columns and boxes ripple green. - Erase and unlimited undo. - Hints fix a mistake first, otherwise they fill the next cell logic can find, so you learn where to look. - Auto-save: leave mid-puzzle and pick up where you stopped. ALSO - Daily check-in with coins. Seven days in a row pays the most. - Optional evening reminder so your streak doesn't slip. - Light and dark themes, sound and vibration switches. - Plays offline. No Wi-Fi and no account needed. QUESTIONS PEOPLE ASK Is there a sudoku game with no mistake limit? Yes. In Mossgrid a wrong digit never ends your game.
