Google Goggles Solves Sudoku 206
mikejuk writes "Ever been frustrated when you can't solve a Sudoku? Well, now there's an app for that. It is just one more capability in the latest version of Google Goggles. All you have to do is point your phone's camera at a Sudoku puzzle, take a snapshot, and pattern recognition and a bit of game logic sorts out the answer. Have you ever had the feeling that AI is getting to be just a little too commonplace?"

The developer of Sudoku Grab for the iPhone - which solves Sudokus via the camera - has a blog post explaining how he did this (in June 2009.)

It's not even to do with numbers, it's just unique identifiers.
You could do it with animals. 1 = cow, 2 = sheep, so one so forth. I like to do it with colours, red, blue, yellow, etc. You could do it with Letters, ABCD...
There is no addition, subtraction, no real computation done with any of the numbers. The only rules are that there has to be 1 of every 9 symbol in each box and each row, and that rule will enforce the subsets that most other people apply (no two identical symbols in the same row or box).
