You probably remember that in Tron: Legacy, Quorra is part of a computer program. She mentions to Sam that she has a hard time beating her father at what seems to be some futuristic strategy game. However, it’s actually a Chinese board game called go, which is quite complex for computers to run.

In fact, it’s so complex that it wasn’t until 2016 that a computer program was able to beat a world go champion. We can’t be sure, but it seems like Quorra was not doing so well because it took computers a long time to beat a human in a match of this board game.
