Game Guide

Go Guide, Rules, and Tips

Go is a two-player territory game in which Black and White take turns placing stones on the intersections of a grid. The rules fit in a few sentences, yet the game is famous for its depth. Play a friend on one device or practice against the built-in AI with adjustable difficulty.

How to Play

  • Black plays first; players then alternate placing one stone on any empty intersection.
  • A stone or group with no empty adjacent points (liberties) is captured and removed.
  • Suicide is not allowed unless the move captures, and the ko rule forbids repeating the previous board position.
  • When both players pass, territory and captures are counted. White receives 6.5 points of komi, and the higher score wins.

Strategy and Tips

  • Corners are easiest to secure, then sides, then the center.
  • Keep your groups connected, and make sure each one can form two separate eyes to live.
  • Count liberties before starting a fight: the group with more liberties usually wins the race.
  • Do not chase every capture; a strong, influential position is often worth more than a few stones.

Controls

MouseTouch

Click or tap an intersection to place a stone. Use Pass when you have no useful move, and turn on coordinates or last-move markers in the settings to follow the game more easily.

Background

Go originated in China more than 2,500 years ago, where it is called weiqi. It spread to Korea and Japan and is regarded as one of the oldest board games still played in its original form. In 2016 it became famous worldwide when AlphaGo defeated top professional Lee Sedol.

Frequently Asked Questions

Can I play Go against the computer?

Yes. Choose Player vs AI and set the AI difficulty. Player vs Player mode lets two people share one screen.

How is the winner decided?

After both players pass, each side counts its surrounded territory plus captures. White adds 6.5 komi to offset moving second, so there are no ties.

Is Go hard to learn?

The rules are simple; the strategy takes a lifetime. Start by learning to capture stones and to make a group with two eyes.
