AI Sudoku Solver & Scanner

Scan, solve, learn, and play three Sudoku variants in one app: Classic Sudoku, Killer Sudoku, and Thermometer Sudoku.

IMPORT PUZZLES IN SECONDS
Use the camera or photo library to scan puzzles from books, newspapers, screenshots, and printed pages. Review and correct recognized digits before saving. For Killer Sudoku, you can also edit cages and sums; for Thermometer Sudoku, you can edit thermometer paths.

HINTS THAT EXPLAIN THE LOGIC
Ask for one logical step at a time. The app highlights the relevant cells, shows placements or candidate removals, and explains which strategy is used and why it works.

THREE WAYS TO PLAY
• Classic Sudoku: solve with row, column, box, and candidate techniques.
• Killer Sudoku: combine Sudoku rules with cage sums, combinations, and the 45 Rule.
• Thermometer Sudoku: use standard Sudoku logic together with paths that strictly increase from the bulb to the tip.

LEARN AND PRACTICE
Study techniques from singles, pairs, and box-line interactions to advanced patterns such as X-Wing, XY-Wing, and chains. View explanations and board examples, then practice individual strategies. Killer and Thermometer hints use their own specialized logic and results generated by the solver.

PUZZLES AND PROGRESS
Choose from four difficulty levels, use notes, resume unfinished games, bookmark favorites, and review your results on the scoreboard.

Many Sudoku solvers only provide the final answer. AI Sudoku Solver & Scanner focuses on the solving process, helping you understand the logic, learn strategies, and solve independently with confidence.
