Zwanzigerrufen (XX-rufen) is an Austrian Tarock game for four players, somewhat simpler than Königrufen, and played with just 40 cards of the Tarock pack. The name means "Call the XX", because you call the tarock-XX to determine who will be your partner.

You can find the rules on this archive copy of Bernhard Krüpl's Tarock Page and on the Zwanzigerrufen Wikipedia page.

Players in North America can obtain Austrian Tarock cards from TaroBear's Lair.

You can play XX-rufen on line against live opponents at the Gametwist site (the interface is in German).

A XX-rufen computer program is available from KEC Austria: Triangle productions.
