What Is Weiqi? (Go / Baduk Explained)
Weiqi is the Chinese name for Go — also called Baduk in Korean. Learn what the game is, how the 19×19 board works, and why millions still play it online.
Answer first: Weiqi (围棋) is the Chinese name for the ancient two-player strategy game known in English as Go and in Korean as Baduk. Players place black and white stones on a grid — usually 19×19 — aiming to control more territory than the opponent.
Go is widely cited as one of the oldest board games still played at a high level; historical sources place its roots in China more than two millennia ago, with deep cultural footprints across East Asia. (Britannica — Go)
● Names
01Weiqi, Go, and Baduk
One game, three primary names — useful for search and for talking to players worldwide.
| Name | Language | Notes |
|---|---|---|
| Weiqi (围棋) | Chinese | Literally “surrounding chess / game of encirclement” |
| Go / Igo (囲碁) | English / Japanese | “Go” is the global English default |
| Baduk (바둑) | Korean | Dominant name in Korea |
If you searched for any of these terms, you are looking at the same rules family. Scoring details (Chinese vs Japanese area/territory counting) can differ slightly by rule set, but the core skill transfers.
