Noughts-and-crosses

Noughts-and-crosses was a game played on Earth.

While held prisoner in the Savoy Hotel, the Seventh Doctor and Ace played noughts-and-crosses to pass the time. The Doctor won seven games and there were one hundred forty draws. (PROSE: Timewyrm: Exodus ^[+]Loading...["Timewyrm: Exodus (novel)"])

Oskar Steinmann claimed that chess was just a more complicated version of noughts and crosses, but the Doctor disagreed. (PROSE: Just War ^[+]Loading...["Just War (novel)"])

From 1967, a television test card would display the image of a girl playing noughts and crosses with a clown. The Fifth Doctor attempted to explain this to Nyssa, but she did not understand.
