So I'm re-watching Squid Game and I'm trying to figure out something with the glass bridge sub-game. How did they know that someone would survive the sub-game? At that point of the series/episodes, there are
players but I counted
glass panels. It's possible that there will be no survivors if they choose incorrectly. Did I miss something earlier or are the game keepers content with someone not winning that year's Squid Game?
