Cut out shapes, get legos out, etc. Tetris puzzles become sooooooo much easier once you have something to physically play with on a grid. (I use graph paper and cut out graph paper squares.)
I think I'm going to have to do this because the tetris puzzles are the ones giving me the most amount of trouble where I theoretically know what the rules are. Stuck on the last puzzle of of the third set of puzzles. Not looking for hints yet because I don't feel like I've exhausted my ideas on it but, again, these frustrate me because I kind of know what the rules are but then I hit a new puzzle where I feel like the prior rule explanations don't build well to what the new puzzle is.
I figured out the Desert Ruin yesterday, finally. The puzzles weren't even hard, but
the trick (because that's what it really is)
Also, I don't know if I just haven't been given the in games tools to figure out the Monastery yet but I have no idea. It just feels like there's no tutorial which makes me think I'm just not in far enough yet.
