Go Goose 雁金

With friends

You get a link to send — whoever opens it takes a seat, or just watches and chats. Any open seat can go to a KataGo bot, from inside the room.

rengo

team Go — teammates share a color, alternating in fixed rotation

co-op

the bigger team plays Black against a lone White — often a bot to gang up on

atari go

first capture wins; the fastest way to teach the rules (humans only)

handicap

Black starts with extra stones; H1 is just Black first at no komi

Solo — against a human-like AI

KataGo's human-style model — calibrated ranks from 20 kyu to 9 dan, plus pros by era.

The famous games

Opens in the viewer — arrow through or hit auto-play. Copy a share link to watch alongside a friend.

Bring any SGF — or open a finished game, or a classic from the shelf — then use Analyze (territory + candidate moves), Review (points lost, move by move), and Human view (what a 20 kyu or a 1920s pro would play), all powered by KataGo.
