As you say, Squid Game is a Korean game, its rules nonsensical to westerners, and it has not taken off in the west, because we all collectively agreed the game is fucking stupid.

So maybe they call the remake something else. Squid Game is only called that, one, because they play children’s games; and two, because Squid Game is the final game in the first season.

A remake wouldn’t be impossible, but they’d have to change the name to something more culturally relevant. There is actually a Hide and Seek movie IIRC. Maybe Capture the Flag?
