This is so much better than a death game manga. The problem with those is that they are FORCED to act, rather than choosing to. The trick behind this game messes with the mind. Much better than, "do this or die." It takes away natural motivation.
This is exactly what i was thinking. The win condition was “get one answer right” not “answer yes to one question at minimum”. I can only assume there was a mistranslation somewhere. Either that or we’re supposed to believe that the stress of the situation prevents them from remembering all of the rules at the same time.
