SudoFlash: AI Sudoku Scanner
Puzzle Solver: Logic & Hints
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Scan. Understand. Solve. Get a single hint, follow every step with an explanation or reveal the full solution. Your Sudoku, your choice.
Scan a printed Sudoku and keep solving on your iPhone. SudoFlash finds the 9×9 grid, reads the printed digits and turns the puzzle into a calm digital board.
CHECK THE SCAN
Review every recognised digit and correct uncertain cells before you continue.
UNDERSTAND THE NEXT MOVE
Ask for one logical hint at a time. SudoFlash shows the digit and explains why it belongs in that cell. You stay in control of the puzzle.
PRIVATE, ON YOUR IPHONE
Core grid detection, digit recognition and Sudoku logic run on your iPhone and work offline. On compatible iOS 27 devices, a few difficult isolated printed digits may use Apple Private Cloud Compute. Full camera images and puzzle history stay on your device. No account is required.
