Ai Igo

A classic Japanese board game that's heavy on strategy and boasts several moods and personalities for the advanced CPU-controlled opponents. Players start with a blank grid and take it in turns to place markers at the points where the grid lines intersect; the main aim is to occupy as much territory as possible and then to capture enemy markers, or groups, by surrounding them. Markers of the same colour joined together along the lines of the grid are a group and can be captured when an opposing marker is placed on the group's last liberty point. Liberties are the adjacent intersections to a single or group of markers. Markers cannot be joined across diagonals to form groups.
