If a row has three empty cells, look at the columns of the empty cells of that row. If either column contains two of the three missing numbers, then the other number is the correct number.

You can also apply this technique to columns.

It can be used with two, three,four or five empty cells in the row or column. Six or more empty cells rarely works.
