Sudoku requires no math
Yes, you did read correctly! Sudoku requires no math to solve. In fact, Sudoku doesn't really involve numbers at all. The boxes in the puzzle could just as easily be filled with nine letters of the alphabet, nine different pictures, or even nine colors! Numbers are only used because they are wellrecognized symbols. I’d be willing to guess that Sudoku’s popularity has suffered because of the numbers. I’m sure it gives many folks the wrong first impression & scares them off… Now don’t get me wrong…I’m not saying you don’t need to think in order to solve a Sudoku puzzle. You definitely need to use the old noggin. In fact, logic and possibility elimination are the keys to the whole thing…
