Skat is a traditional German card game for three players played with a standard card deck, roughly 200 years old. The game is based on Schafkopf, Ombre (bidding) and Tarock (remaining cards).

A play comprises two phases: first an intricate bidding process to decide the solo player who choses the type of game to be played in the second phase, the actual playing of tricks.

The latest revision of rules as approved by both the International Skat Players Association (ISPA) and the German Skat Association (DSkV) dates back to 1998. The BGA adaption follows these rules, but also offers some hobbyist rules (Ramsch, Contra/Re).
