Teach them young, they say, and they will grow up to the kind of little people you want them to be. When you encourage Sudoku, what kind of kids are you raising? You raise them to be creative and logical. You raise them to be patient and investigative. You raise them to never back down from a good challenge. You raise them in Sudoku puzzles.
