Scan, solve, and play Sudoku in one app. Explore different solving paths with Move Tree, a visual history of your attempts. CAMERA & PICTURE SOLVER Point the camera at a printed or handwritten Sudoku board to recognize and solve it in real time, or choose an image from Photos. Correct recognized digits before solving, enlarge the detected board with pinch gestures, save scanned puzzles to history, and reopen them later. The solver supports 9×9 and 4×4 boards and can: • Solve the full puzzle. • Reveal one cell. • Identify the most useful cell to solve next. • Show possible numbers as pencil marks. • Flag conflicting, unsolvable, and completed boards. • Display focused and clear board views. • Provide live framing, lighting, and steadiness guidance. PLAY SUDOKU • Choose from 155 built-in Easy, Hard, and Expert puzzles. • Turn a Sudoku scanned with the camera or selected from Photos into a playable board. • Resume games, track completion, and remove saved scanned puzzles from your library. • Use Undo, Redo, Notes, Smart Notes, and cell highlighting. • Detect both immediate row/column/box conflicts and moves that leave the puzzle with no valid solution. • Ask for a Hint that selects a strong next cell. Optional explainable hints describe why the cell was chosen. • Review player statistics, solving times, streaks, and hint-free wins. MOVE TREE Keep track of your ideas as you solve. Move Tree shows your puzzle’s history as a visual tree, with miniature boards highlighting what changed at each step. • Preview earlier positions without changing your current game. • Continue from an earlier position and try another approach while preserving existing branches. • Bookmark positions you want to revisit. • Pinch to zoom, drag to pan, and collapse branches to keep the view manageable. • Resume your saved puzzle with its branches and bookmarks intact.
