Looks like I'm continuing my Frustration puzzles with a second one, because I didn't think that I would be making more. Yet, here I am! I am absolutely disgusted with all those illogical symmetrical puzzles because they are no fun whatsoever. So, what is someone to do with these puzzles that have all these 1s? Just guess and hope for the best they get the answer eventually. Of course, I'm not cruel, so I'll give you some fillings on one side, and then you can figure out the rest through symmetry.

Fill out: C6R3, C6R6, C1R7, C3R4, then use vertical symmetry to figure it out.
