The game is common in the German-speaking region among children and young people.
The aim is to collect four cards of the same value (a so-called quartet) in one's hand (e. g. four Unters or Bauern).
A player who achieves the aim of having four cards of equal rank in hand, places them face up and calls "Fingerkloppe!".
In a two-hand game, the loser is the one who has not managed to collect four cards of a kind.
In the second case, the loser also names a desired card and also whether the talon is to be counted down from the top or up from the bottom.
