Citadel is a game of skill, played by two people, in which two different colored sets of ten pieces each, are played on a cornered checkered field of contrasting colors. These ten pieces are of four kinds, each having different powers and values. There is only one citadel piece in each set and it is the object of each player to protect his own citadel piece and to capture that of his opponent, to win the game. - BoardGameGeek
