Postby jeffcia » Fri Jan 23, 2015 2:06 pm

can somebody please give me an algorithm that will help me to fill in the last few here. I can solve it using a guess and check, but would prefer to have an algorithm. Thanks in advance

There is a naked pair in column 8, and then singles to the end.

Thanks!! I was looking for naked pairs/triples only within each big square!! I didn't think to look above for the 89.
