五目並べ

• IPA^(key): [ɡo̞mo̞kɯ̟na̠ɾa̠be̞]

From 五(ご) (go, “five”) + 目(もく) (moku, “piece, mark”) + 並(なら)べ (narabe, “line up”). Literally “five pieces in a row.”

五(ご)目(もく)並(なら)べ • (gomokunarabe) 

1. a traditional two‑player board game played on a Go board, in which players alternately place black and white stones with the objective of being the first to align five stones in a row vertically, horizontally, or diagonally

• Typically played on a 19×19 Go board, though 15×15 is common in competitive play.
• Standard rules strongly favor the first player (black); therefore, international tournaments often use 連珠(れんじゅ) (renju) rules, which restrict certain opening moves.
