Gameplay is a lot like Tetris, but instead of lines, the pieces break like Go captures. In Go, a stone is captured by surrounding it by stones of the opposing color (or by the edge of the gameboard). More than one stone may be surrounded in this way, and the more stones you capture at once, the more points you receive.

Groups of stones are also removed from the gameboard when they surround two or more eyes. Stones removed from the board this way are counted as "Territory". See the in-game for more details.

You also get more points at higher levels.

Enjoy!
