It's not like I'm opposed to them or anything (I mean I'm a little annoyed that I can't do them alone and I'm pretty much the only person in my friend group who both has Escape Sim and likes sudokus, so I do feel like I'm missing out but that's not really the maps' fault), I'm just confused. Like, A) how does it work without arbitrarily separating the board (which seems counterproductive for sudoku) and B) my first thought when doing a sudoku isn't "Wow, I wish this were co-op!" so the motivation is lost on me as well.

Unless people are just labeling them 2P-only for no reason, like a bunch of maps that are tagged as 2+ only despite being perfectly doable singleplayer (I don't understand you people, why do you do this to me)
