Territory

The territory of a player is usually meant to signify the part of the board that the player controls. One way to define it is to say that it is the set of hexes occupied by the player, plus those adjacent to cells occupied by the player.

However, it is often better to consider it in a looser sense. For example, if Red has an outpost on the fourth row, which can be used as a Ladder escape, it makes sense to consider the area between this and the edge as Red's territory.
