Trull (cards)
The trull is a trio of three special trump cards used in Tarock games in Austria and other countries that have a much higher card value than the other trumps. The individual cards are known as trull cards (Trullstücke). The word trul is derived from the French tous les trois which means "all three".
In spite of its French roots the term is not common in the game of French tarot, where the trull cards are called les bouts ("butts") or, in earlier times, les oudlers, which has no other meaning.
Introduction
The games of the tarot (French) or Tarock (German) family are distinguished mainly in that, in addition to the suit cards, their decks have a series of 21 classical, permanent trumps, most of which are numbered with Roman or Arabic numerals. In games of German-language origin the trumps are also called tarocks. ebenfalls als Tarock bezeichnet. The special role of the 'fool' (Narren) is described below.
Tarock games are trick-taking card games, in which the cards have values in addition to their trick-taking power or ranking. In German these values are known as Augen which means "pips" or "card points". In most variants of Tarock there is, however, a complex system of scoring using fractions (e. g. 4 1/3), which are subsequently rounded to the nearest natural number.
