Cliff Go

Blast factories, seize territoryA Go-style game you can play without knowing Go

Red and Blue take turns building one factory at a time.
Whoever has more factories and chimneys in total wins. (Blue, moving second, gets 7.5 bonus points)
Factories surrounded by the opponent explode.
Surround one empty square with factories to make a courtyard. With two courtyards, chimneys rise and a flag goes up on the factories.
The game ends when both pass in a row. Then factories without a flag explode, and squares surrounded by flagged factories automatically become yours.

Red 0Blue 0+7.5

Based on Chinese rules: area scoring, komi 7.5.
But to keep it simple for beginners, at the end, any group without two one-point eyes is captured.
(Groups in seki and groups with one big eye are too.)
During a game, tap "Go board" to switch to a board-and-stones view.

About this game

Stones become factories that explode when surrounded: a Go board game you can understand by watching. Free in your browser, no sign-up.

A game in progress, with red and blue factories in a fortress above the clouds
  • See the rules: Liberties appear as lamps on factory vents, with a warning when only one is left. Capturing stones blows up the factories.
  • A clear finish: Factories without chimneys explode at the end and territory is counted automatically, with no arguing over dead stones.
  • A fortress above the clouds: Watch chain explosions and rising chimneys in a storybook 3D town, as the sky turns from morning to night.
  • Real Go underneath: Your Go tactics still work, and you can switch to a board-and-stones view. 10 computer levels, the top ones trained by self-play.
  • A different town each time: Play from 7×7 to 19×19, on random town shapes or with walls you place yourself, or just watch the computer play itself.
