I used a walkthrough to beat one puzzle in a game that I was stuck on for ages and I found a secret in a game after someone I know mentioned it.

Ehh if desperate I would say not really. I know a lot of people use walk throughs also although not a puzzle game my first play through of dark souls I looked online for help in doing a few things also did this for mabinogi's crazy quests

I would say it is a situation dependent grey area.

I don't know why it even matters, how can you "cheat" at a single-player game? It's only "cheating" if you feel like you cheated yourself, imo.

I would much prefer to look something up than just never progress and never get to enjoy the game.

I wouldn't really call walkthroughs a way of cheating.

It's fine to use walkthroughs, especially in RPGs.

They're your best friend in every RPG game out there.
