Draughts was a board game.
Adric and Nyssa played draughts on Deva Loka. Tegan tried to help Nyssa by making a move for her; this only improved Adric's game.
Anicca and Anatta, manifestations of the Mara, played draughts in a dream of Tegan's. (TV: Kinda)
Haliard and Ferras frequently played during their leisure time at the Cimmeria IV base. Haliard was almost always the victor, though Charlotte Pollard easily beat him. (AUDIO: Embrace the Darkness)
