Thanks to everyone who said they had to guess a little, I think I got something now. I was struggling because a lot of instruction websites I ran in to said "if you're guessing, you're doing it wrong" but then I was stuck with no where to go BUT guess.
I agree with this a lot, something about it felt not very satisfying.I solved it. But personally, it wasn't as satisfying as I'd hoped it would be.
My issue with this puzzle is that, you can start solving it using standard nonogram rules until it comes to a dead end. Then you have to proceed with guessing based on symmetry. Then you go back to using nonogram rules.
