I can’t get 18 Pentopia to work even without the time pressure of the contest. Broken it in many different ways. What am I missing?

perhaps you can link to an image of your progress?

wow, absolutely awful round, but considering how bad I am at all the non-akari genres in general I guess that's not surprising. Kept breaking both of the easier pentopia, I need to go back and solve these legitimately to figure out where I'm going wrong.

As I say, I'm not deliberately guessing, I just get to a broken point. I think this is the last common point before I start trying different things, so I reckon something is wrong by this point.

@pinkagape I can say this is correct actually. Your mistake is probably coming after this. From here, you may see contradictions in 2 of them if you try the 3 different possibilities for the r1c8 clue.

I was something like 25 seconds away from a completion here. Fun set!

You saying there were three options in the top right was all I needed. I only had two and found the contradictions multiple times. Thanks!

Really nice puzzles, especially the Akari (Skyscrapers)
