Win the whole map and you will win! Keep an eye on your food supplies though! As Napoleon said: "The army marches on its stomach", so no food means your troops can't fight. Taking squares on the map and connecting them to your cities will ensure that the food keeps coming, so try to keep your kingdom connected. Are you strategic enough to win the Conq.io?
