The first mention of the game Mus was made by the philologist and Basque Jesuit Manuel de Larramendi in 1754 in his dictionary of three languages (Basque, Spanish and Latin)

Most historians say that this mus game with a 40-card deck was born in the Basque Country. There is great care that the name Mus comes from the kiss, since the kiss is the best game, the gesture of expressing the 31. The expression of the hordago is also understood to come from the indicative place, the expression that is usually said when the bet reaches its maximum level.

Players are dealt four cards. Once these cards are dealt, there are four phases (or plays) in this order:

Handira: Who has the largest cards.

Txikira: Who has the smallest cards.

Pairs: Who has the best pairs, to what extent the four cards you’ve had are similar.

Game: Who has the best game. It depends on the sum of the values of the cards and requires at least 31 points. If no one gets that much, you play the point. In this case, the best score will be 30 points.
