SPOILERS GIVEN IN POST!!! DO NOT LOOK IF YOU HAVE NOT SOLVE THIS WEEK'S FREE TIC-TAC-TOE LOGIC!!!

Anyways, here's what the program and I agree on:

OXOXOXOX
XXOOXOXO
XOX - -OXO
OXO - -XOX
XOXOXOOX
OXOXOXXO
OOXXOXOX
XOXOXOXO

The program wants

XO
OX

in the missing four spaces. And this is a valid solution. However,

OX
XO

is also a valid solution.

Hi, there's a rule that all rows and columns must be unique. However, in your second solution, the 3rd and 8th rows are the same.

Thanks. I actually missed that rule, since it's so rarely needed.

This may sound nit-picky, but it is all rows and all columns must be unique, not all rows and columns. They actually changed the wording of that rule after I asked why their solution to one puzzle was valid since row X and column Y were identical.

I honestly read the original wording to mean no row could match any other row or column and the same for columns. Not that no row could match any other row and no column any other column.

As I said, it seems nit-picky now, but oh well. ;)
