Cited on HN 4 times, 2014–2026, never outright recommended score 0
Years with an HN recommendation, 2007–2026

HN cites it as shorthand for the tic-tac-toe lesson, especially in threads about AI and nuclear strategy or games that cannot be won.

The final scene of the 1983 film WarGames, in which the WOPR computer runs through nuclear war scenarios and concludes that the only winning move is not to play. It is a six-minute clip uploaded in higher quality than earlier copies.

“Make LLM's win every game of tic-tac-toe and see if it reaches the same conclusion of WOPR.” (HN, 2026)

on HN thread AIs can't stop recommending nuclear strikes in war game simulations
They have no real stake in any decision they make. And they are not human. Not even a sociopath or psychopathic human. At best they might be able to estimate casualties. LLM's probably can't even reach the logic conclusion of the fictional WOPR Joshua from the movie Wargames [1]. Make LLM's win every game of tic-tac-toe and see if it reaches the same conclusion of WOPR. [1] [1] - [this video] [video][6m][tic-tac-toe]
WarGames ending where WOPR learns tic-tac-toe lesson
