Gomoku
Gomoku, also called "Five in a Row", is an abstract strategy board game. It is traditionally played with Go pieces (black and white stones) on a Go board, using 15×15 of the 19×19 grid intersections. Because pieces are not moved or removed from the board, Gomoku may also be played as a paper-and-pencil game. The game is known in several countries under different names.
Go (game)
Go has also been featured in a number of television series. Starz's science fiction thriller "Counterpart", for instance, is rich in references (the opening itself featuring developments on a Go board), including applications of the game's metaphors, a book about life and death being displayed, and Go matches, accurately played, relevant to the plot. Another example is Syfy's "12 Monkeys": In the first season's episode "Atari", one of the characters explains the homonymous concept, using it as an analogy to the situation he was facing, and his son is briefly seen playing Go later on.
