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)
The word "Go" is derived from the full Japanese name "igo", which is derived from its Chinese name "weiqi" (Middle Chinese "hjwɨj-gi"), which roughly translates as "board game of surrounding" or "encircling game". To differentiate the game from the common English verb "to go", "g" is often capitalized, or, in events sponsored by the Ing Chang-ki Foundation, it is spelled "goe".
