Königrufen or Königsrufen (German: "Call the King") is a four-player, trick-taking card game of the tarot family, played in Austria, Southern Tyrol, and Slovenia. As with other regional tarot card games, it is usually called Tarock (the German term for tarot card games) by its players. It is the only variant of Tarock that is played over most of Austria and, in 2001, was the most popular card game in Austria after Schnapsen and Rommé. By 2015, it had become "the favourite card game of Austrians". It has been described as the most interesting tarot game for four players, the "Game of Kings", a game that requires intelligence and, with 22 trumps in play, as good "training for the brain".
