Puzzles #130, #131 & #132: Kurodoko Trio

So it turns out I've now solved every Kurodoko on puzz.link except one. Here's three more I made, all inspired by either things I found in solving, or musings about the genre I had. No bifurcation is necessary and the logic is well worth discovering, here!

This first one is probably the most difficult of the three, but also my favorite.

Likely the easiest, but a pleasant solve from those who tested it.

The idea in this third puzzle can definitely be used for some more interesting or complicated deductions. It turned out exactly how I wanted it to in the end, though.
