Klaverjassen is a popular card game in the Netherlands that is traditionally played in cafes, social clubs, and at home. The game is designed for four players who sit opposite each other in pairs. The game has several variations, which are named after the cities where they originated: Amsterdam and Rotterdam.
The goal of the game is to get as many points as you can in 16 hands. In competition games, the players on one table will rotate so that each of the other three players has a partner, resulting in three sets of 16 hands.
The goal of each hand is for the player (and partner) who picks trumps to collect more than half of the available points. If they fail to do so, they receive no points and the opposing pair receives all of them.
