Yes, I've been playing Sudoku for a bit, but I'm just curious, when you do medium or hard Sudoku boards, do you basically just end up guessing? Like when you have two squares and you know that they will be either 1 or 4, and basically you can't eliminate 1 or 4 by any logical reasoning. What do you do then? In the example above, I've also done "possible numbers" for all the remaining squares, and I still can't eliminate 1 or 4. |
