The wooden board used in the game of Go, traditionally with 19 x 19 grid lines for placing stones.
From Japanese 'gōban' (碁盤), where 'gō' (碁) means the game of Go and 'ban' (盤) means board. The term entered English from Japanese gaming culture.
The goban's 19×19 grid isn't arbitrary—mathematicians discovered it creates exactly 361 intersections, a number that was cosmically significant in ancient Chinese culture, connecting a game board to astronomy and philosophy!
