How to play Stones

Stones is the ancient game of Go on a quick 9×9 board: place black and white stones in turn, surround territory, and capture stones that run out of room. The side with more area at the end wins.

Controls: Tap (or click) a point on the board to place your stone; a faint stone shows where it will go. Press PASS when there's nothing more to gain. Two passes in a row end the game.

Tips

  • Start near the middle or on the star points. Corners are easiest to make territory in, then the sides, then the centre.
  • A stone or group with one liberty left is in atari: save it by adding a liberty, or let it go if it's already lost.
  • A group needs two separate eyes to live for ever. Make room for them, and try to stop the other side's groups from getting two.
  • Don't play inside your own territory or fill your own eyes. When there's nothing left to gain, pass.
  • White gets 6.5 points of komi for moving second, so Black has to win by 7.
  • When both players pass, stones that can't live are counted as captured and the board is scored.
