Sudoku Discussions: A little tip to help solve the puzzles: "So far this method has worked.
1 After obvious initial entries fill in the blank cells with all allowable numbers.
Now look for a single occurence of any one number:
a) in any row
b) in any column
c) in any of the boxes
when you find a single occurrence then that is the number . Now eliminate that number from the box and row and column.
Then look for another singleton and repeat the process when you find one."
