In Kingdom Builder, the players create their own kingdoms by skillfully building their settlements, aiming to earn the most gold at the end of the game.
Nine different kinds of terrain are on the variable game board, including locations and castles. During his turn, a player plays his terrain card and builds three settlements on three hexes of this kind. If possible, a new settlement must be built next to one of that player’s existing settlements. When building next to a location, the player may seize an extra action tile that he may use from his next turn on. These extra actions allow extraordinary actions such as moving your settlements.
