Go Rules

Objective

Surround more territory than your opponent by the end of the game. Capture enemy stones by surrounding them completely.

The Board

Go is played on a 19×19 grid. Stones are placed on the intersections, not inside the squares.

How to Play

• Tap an empty intersection to place your stone.
• Black always plays first.
• Players alternate turns.

Capture

• A stone (or connected group of same-color stones) is captured when all of its adjacent intersections are occupied by the opponent.
• Captured stones are removed from the board and counted as prisoners.

Ko Rule

You cannot place a stone that recreates the exact board position from the previous move. This prevents infinite loops.

Suicide Rule

You cannot place a stone in a position where it would have no liberties, unless doing so captures enemy stones.

Passing

Instead of placing a stone, a player may Pass. When both players pass consecutively, the game ends.

Scoring

Territory (empty intersections surrounded by your stones) + prisoners captured. Black gives White 6.5 komi points to compensate for moving first. Highest score wins.
