As I said on the question... that is not a game. A game is defined by actors making decisions.
Any length of text is not a game. You read it. It's a book. Only when it includes a decision making process like a choose-your-own-adventure, it becomes a game, because you have now become an actor with agency.
Any video is not a game. You watch it. It's a movie. Unless it becomes very a different movie every time the player makes a decision. Then we call it a video game.
A deck of playing cards is not a game. Until you define rules how and when to make decisions and what consequences those decisions have, then it becomes a card game.
Potatoes has no in-game decisions. It has a single decision to make, and you can make that decision without any context, even before starting the game. You could even say it is not a real decision, because there is a mathematical optimization and you can make a good decision or a bad decision, but again, you can calculate that beforehand with no uncertainty.
It also contains no role playing. Someone said you can play it out. Yes. You can. It is not explicitely forbidden by the rules. But is that really our argument why it is an RPG? Because R is not explicitely forbidden? I could claim that doing my math homework on the bus on my way to school is an RPG. The teacher never said I was forbidden to roleplay and I think my elven x² was level 3 by the time the bus stopped.
We have pretty clear lines here. Choose-Your-Own-Adventure are not roleplaying by our standards. Games like Hero Quest are not roleplaying. Why? Because while you certainly can roleplay (and roleplayers probably will), they do not contain any material to do so.
So no. It is neither a game, nor roleplaying. So I don't see why it should be on topic here.
