Although there were already similar bonuses in "Hundertspiel", it was only in the 20th century that the idea arose of extending the bonus of the "Pagat ultimo" to higher tarocks and earlier tricks, initially to the Eagle Owl ("Uhu"). In 1937, this name was first used for the Tarock II in Franz Unger's "Kleiner Lehrbuch des Tarockes in seinen schönsten Arten" ("Little Textbook of Tarock in its Best Ways"); there, however, the bonus was awarded for playing the Owl in the last trick. Later, the penultimate trick became the norm.
