German-suited playing cards are a very common style of traditional playing card used in many parts of Central Europe characterised by 32- or 36-card packs with the suits of Acorns, Leaves, Hearts and Bells. The German suit system is one of the oldest, becoming standard around 1450 and, a few decades later, influencing the design of the now international French suit system of Clubs, Spades, Hearts and Diamonds. Today German-suited playing cards are common in south and east Germany, Austria, German-speaking Switzerland, Liechtenstein, north Italy, Hungary, Czech Republic, Slovakia, Slovenia, Croatia, Bosnia, northern Serbia, southern Poland and central and western Romania.

A playing card is a piece of specially prepared card stock, heavy paper, thin cardboard, plastic-coated paper, cotton-paper blend, or thin plastic that is marked with distinguishing motifs. Often the front (face) and back of each card has a finish to make handling easier. They are most commonly used for playing card games, and are also used in magic tricks, cardistry, card throwing, and card houses; cards may also be collected. Playing cards are typically palm-sized for convenient handling, and usually are sold together in a set as a deck of cards or pack of cards.
