Mus is a 4-player card game with Basque roots and is often played in Spain.
At the beginning of the game the players are divided into two teams of two, who play against one another. The team partners always sit opposite each other and have the opportunity to communicate using set gestures. After receiving the cards, the players must call either “Mus” or “No Mus”. A “Mus” means that the player would like to exchange cards. The aim of the game is to reach 40 points.
