    This is a very clever concept, (and a challenging puzzle). I really enjoyed the new kinds of thinking necessary to solve this one.

    Thanks guys, I’m glad you enjoyed the variation.

    Of course everyone’s experience may vary but I think this puzzle remains rather difficult even towards the end.

      I didn’t need to use that logic, but it was interesting that I found the location of all the stars before I confirmed that it was a valid Star Battle grid. Even then, it took me several minutes to convince myself that the grid was both valid and unique.
