German playing cards are a style of playing cards used is some parts of Central Europe. Playing cards (Spielkarten) entered German-speaking lands around the late 1370s. After much experimentation, the cards settled into new suits of Acorns (Eichel), Leaves (Grün or Blatt), Hearts (Herz) and Bells (Schelle) around 1450. Closely related Swiss playing cards are used in German-speaking Switzerland. Cards of these types spread throughout Central Europe into areas that were once under German or Austrian control (Hungary, Slovenia, Slovakia, Czech Republic, Croatia, Transylvania, Vojvodina, South Tyrol, Transcarpathia, and parts of Poland). They were also produced and used as far east as Russia until the early 20th century. German-suited decks are not well known all over these countries including parts of Germany itself as they are undergoing strong competition from French playing cards. Traditional card games in which the German suit is used include Skat, Schafkopf and Doppelkopf.
