Jass is the name of a trick taking card game. It is popular in Switzerland, Liechtenstein, Vorarlberg (Austria) and parts of Bolzano-Bozen (Italy) and is sometimes considered as the national game in Switzerland.
It is played with a deck of 36 cards (A, K, Q, J, 10, 9, 8, 7, 6), used with French, swiss-german or Austrian cards.
While many variants of the game exist, with 2 to 6 players, the most commonly played is called chibre (Schieber), and involves 2 teams of 2 players playing against each other.
The point values for the cards are as follows:
In trump: J=20, 9=14, A=11, K=4, Q=3, 10=10 (8, 7, & 6 have no point value)
non-trump: A=11, K=4, Q=3, J= 2, 10=10 (9, 8, 7, & 6 have no point value)
