The episode Atari from season 2 sees José Ramse refer a number of time to Atari. No – he’s not talking about the Atari you play space invaders on.

Atari is a term from the game Go – an ancient Chinese board game played with Marbles. Atari is a term that describes something similar to check in Chess.

Ramse uses it as a metaphor for being out of moves, with no alternative options remaining.

We see Ramse teaching his son Sam the game at the end of the episode.
