Google Goggles has a peculiar Sudoku-solving feature. If you want the answers because you can't get past a certain point or need them to check your work, here's how:
Step 1:
Launch Google Goggles and take a picture of the Sudoku puzzle.
Step 2:
Once Google Goggles recognizes it as a Sudoku puzzle, you'll see a notification box that states that it is a Sudoku puzzle. Tap the notification area to move on to the next step.
Step 3:
The following screen will display links to Sudoku sites as well as the option to solve the puzzle you just scanned. Tap "Solve" to have Google Goggles solve it.
Step 4:
The next screen will display an animation of the numbers being filled out until the puzzle has been completely solved.
There you go. As the uncle in "Spider-Man" once said, "With great power, comes great responsibility." Egregious abuse of this feature will likely defeat the mind-sharpening abilities of Sudoku, so beware!
