Lost interest on 3rd beginner puzzle when validation failed for multiple valid solutions.

  What solutions were you trying? As far as I can tell, the puzzle is fully constrained. From the start, the bottom-left cell as well as the right column can be solved just from the starting hints, and then you can derive the top-left cell per the backreference. In particular, you can reframe the right column's hint as (AB|OO|OR), and only one of those satisfies the bottom row's hint.

    Not so. Something as simple as "OO\nDO" should be valid. But also "OO\nDD" and myriad other solutions.

      Ah. The difference is that you're trying partial matches, as opposed to full matches from the specified patterns. edit: and by full match (since this seems to be the source of some confusion in another subthread), I explicitly mean anchored with your \A...\Z or whatever you want to use.
