A simple Sudoku game. Put a number from 1 to 9 in each empty square, but without duplicating that number in any row, column, or larger square of nine individual squares.
I’ve got a particular game this far. So close. How hard could it be? We could trial and error the remainder; it wouldn’t take long, but is there a solution that doesn’t require that initial trial and error guess?
