Thirty-One
Jass Group is a card game that is very popular in the Netherlands. The game is played with four players. The two players sitting opposite each other form a team, so North and South are a team, and East and West are a team. In each round, a trump card is chosen and the first player decided whether to play or pass. When a player selects to play, they do so on the assumption that their team will be able to win more than half the points allotted per game. Players take turns to play cards with the aim of winning the round. After 8 rounds, the point total is calculated to determine the winning team. There are a number of rule variations players can choose in this game, including Rotterdam rules and Amsterdam rules.
The game features a full overview of the rules for players to consult.
