In Gomoku the dark color normally plays first, and players alternate in placing a stone of their color on an empty intersection. The winner is the first player to get an unbroken row of five stones horizontally, vertically, or diagonally.
The origin of Gomoku comes from China but the name "Gomoku" is from the Japanese language. Gomoku is also known as Gobang, Omok and Five In A Row.
