Online Go

Overview

Stones on a grid, territory on the line, and a rule set so spare it fits on a postcard — Go is the ancient East Asian strategy game whose depth has kept players and, more recently, researchers occupied for well over two thousand years. Two players, black and white, take turns placing stones on the intersections of a lined board, and the goal is to wall off more empty territory than the opponent while capturing enemy stones by surrounding them with no liberties left. The rules say almost nothing — place a stone, capture when a group has no breathing room, pass if you must — yet the space of possible games is vast enough that even strong computers were historically outplayed by humans long after chess fell. The "online" part is the draw here: this build links into live multiplayer Go, so instead of a single computer opponent you are matching against real players, with ranked play and a community that keeps games flowing at almost any hour.

How to Play

Input is mouse or touch only, since this is not a keyboard-driven game. Click an intersection to place a stone, or tap it on a touch screen; black moves first, then the players alternate, and a placed stone never moves, though it can be captured and removed if it runs out of liberties. The matchmaking pairs you with another live player at roughly your level, and ranked play records the result toward your standing. Because the opponent is a real person, games run at human pace, with time controls keeping things moving. When neither side wants to play another stone, both players pass and the game scores the territory each side has surrounded, awarding the win to the larger area after the standard compensation is applied.

Tips & Strategy

Play the corners first, then the sides, then the center — the old Go proverb holds because corner territory needs only two walls to secure, a side needs three, and the center needs four. Build influence by playing on the third or fourth line from the edge: the third line is territory-oriented, the fourth line aims at influence toward the center, and most opening shapes use some of each. Do not get attached to weak groups; a group that cannot be saved should be abandoned so you can invest elsewhere, and trying to rescue dead stones is the fastest way to fall behind. When you attack, attack toward territory you want to build, so that even a failed attack leaves you thicker. Against a human opponent, think in terms of whole-board balance rather than local fights, since winning one corner while losing the other three is still a loss.
