Play Go online free
Go, also called Baduk in Korea and Weiqi in China, is the oldest board game still played in its original form. TseGo lets you play it free in the browser or on your phone: a KataGo neural-network engine that runs fully offline, bots that genuinely play at their stated rank from 20 kyu to 5 dan, 15,000 tsumego puzzles, and ranked online games on 9x9, 13x13 and 19x19 boards under Japanese or Chinese rules. No signup, no ads in play.
