AtariGo for Palm by Tapani Raiko

The one who makes the first capture wins. The game starts on a 10 by 10 board with a crosscut in the middle. No passing.

Try it as a soft introduction to Go or as a nice boardgame as itself. You can check the rules below.

The beginning of a game.

An example game.

The players alternately place stones of their own colour to empty points on the board. Black is first. Once a stone is on the board, it is never moved or removed. The first player to surround some opponent stones wins. The surrounding is clarified below.

Stones of the same colour that touch each other form strings. Top left corner shows two black strings; one with three stones and the other with just one.
A string is surrounded when it does not touch an empty point. The black string in the top right corner is surrounded by six white stones and the one in bottom right corner is surrounded by just two stones.

If black plays to the blue point, he makes a suicide and loses the game. On the other hand, if he first plays to the red point and later to the blue point, he wins. (even with his own stone surrounded!)
Neither player wants to play in the bottom left corner, since the other player can win by playing to the other point. The white string is therefore safe as long as there is room to play elsewhere on the board.
