Their plots both revolve around table games. The protagonists show a god-like mastery of their games, though they show no interest in the game at first. The protagonists' rivals spur them on to become better at the game in similar ways. The supporting casts, for the minimal amount of screentime they get comparatively, are both very distinctive and memorable. The characters in Saki are all skilled female players with few skilled males, while it is the opposite case in Hikaru no Go.
