Tarock games, Dummett's Type III, differ from other forms in the function of the Fool which is now simply the highest trump. Games of this category include Cego, Zwanzigerrufen and Königrufen. These games use the 54 card French suited Cego or Industrie und Glück decks that strip certain pip cards. The games are widely played in the Upper Rhine valley and its surrounding hills such as the Black forest or the Vosges, and the countries within the boundaries of the former Austro-Hungarian Monarchy, for which even the name 'Tarockania' (Tarockanien) has been coined: the Austrian variation of the game (and the variations thereof) is thus still widely popular among all classes and generations in Slovenia and Croatia, while in Hungary different rules are applied. The Swiss game of Troggu is believed to be an intermediary form linking the older tarot games to the Central European ones.
