2020-09-05: confused seal 10: Connecting Puzzles

See the first post in this series for more information. [important note: remarried seal has become "seal with a confusing relationship status" (abbreviated as confused seal), since August is over but Freddie is continuing intermittently as sporadic seal, and TheGreatEscaper has begun making a daily loop puzzle as bacheloop seal]

At the time of writing, there are only 6 Araf puzzles in the puzz.link database. So I decided to fix that!

The first one is a mini-demo of a deduction required for the second one, so it's a bit of a spoiler for the big puzzle.

Was trying to make a shakashaka to demonstrate some basic deductions, but ended up with a mediocre puzzle instead, which was just decent enough to not throw away.

I made these puzzles to demonstrate how "penalty theory" in Heyawake can be applied locally.

This one is well worth doing logically – the deductions aren't hard but work well together.

This is the first standard logic puzzle I made – I don't think it's very good, but it's not bad either.
