Gomoku originated around the Hwang Ho delta
in China as early as 2000 BC. This spread to Japan in 7th century
BC where Gomoku became established as a game of excellence and Japan
the centre for this game. Gomoku's popularity is fuelled by being
playable on a Go (AKA: Wei-chi and Badu) board with Go counters,
so also became a popular quick alternative to the longer and harder
game of Go.
