OCR
โ
โ
To seize a printed puzzle by OCR will need some cleverness: perfect (very) close-up focus, no motion-blurring, filling up the square window with the puzzle grid but a tiny white margin.
Check that all the digits are correct, and if not change them by hand - or retry OCR.
Don't forget "done" to leave!
