> knowing the rules
Only because I've solved them first. As in I didn't look up the rules until I was done with all the puzzles just because I wanted to see if there's a decent spoiler free explanation for Chazina.
> able to fiddle with the game yourself
That really comes more into play for the puzzles where you have to move your character to solve them. Most of the ones where you're stationary can theoretically be solved pen and paper, although it is a slight advantage to be able to trace it ingame yea.
