Mus: The Spanish Bluffing Game - A Comprehensive Guide

Mus is a popular, Basque-origin card game that originated in Spain, designed for 4 players in fixed partnerships. Unlike many card games, Mus is a partnership game that does not require money to play, making it accessible to all. This guide aims to provide a clear, precise, and enjoyable introduction to the game, helping you to understand the rules, strategies, and common variations of Mus.

Game Overview

Mus is a part of the vying games category and is played with a standard 40-card Spanish deck, available on Amazon (baraja espanola mus). The suits in the deck are swords, batons, cups, and coins, and each suit consists of Rey (R, King), Caballo (C, Horse), Sota (S, Knight), 7, 6, 5, 4, 3, 2, and Ace (A). In Mus, the suits have no significance, and the 3's are equivalent to kings, while 2's are equivalent to aces.

Objective

The objective of Mus is to score 40 points as a team before your opponents, with games usually played best of three. Points are scored by having the best hand in one of four categories: Grande (high), Chica (low), Pares (pairs), and Juego (game).

Setup

The dealer shuffles the deck, and the player to their left cuts the cards. The dealer then deals one card at a time, anticlockwise, to each player until each player has four cards. The player to the dealer's right speaks first in each round of betting and is known as the mano.

How to Play

Mus begins with a proposal by the mano that all four players should have a chance to improve their hands by discarding one or more cards. This can only happen if all four players agree. Players speak in turn, starting with the mano, and if all agree to change cards by saying "Mus," the discard takes place as described below. If any player disagrees by saying "No hay mus," there is no opportunity to discard, and the game proceeds immediately to the first round of betting.

If everyone says "Mus," each player in turn discards one to four cards face down and is dealt an equal number of new cards. The players then look at their new hands, and there is another opportunity to propose "Mus" as before. If the players keep on agreeing to Mus, eventually, the dealer will run out of cards. If this happens while more than one player requires cards, all discards are shuffled to form a new stock to deal from. If the cards run out while only one player is short, then the cards excluding that player's discard are shuffled to make a new stock.

The players compete to establish who has the best cards in each of four different categories: Grande (high), Chica (low), Pares (pairs), and Juego (game). The objective is to have the best hand in each of these categories, as explained in the following sections.

Scoring and End of Game

After the final round of betting, there is a showdown where the hands of the players are compared, and points are calculated. Points are scored for having the best hand in each category and can be increased by betting during the betting rounds.

In the absence of betting on the Grande or Chica, the side with the best hand wins one stone. If there is no betting on the Pares, whoever has the best hand scores for their own and their partner's hand as follows:

  • Par Simple: 1 stone
  • Medias: 2 stones
  • Duples: 3 stones

and the other side scores nothing for any Pares they may hold.

For the Juego (game), players add up the point values of the cards in their hand. To have a Juego, you must have at least 31 points. The best Juego is a hand of exactly 31 points. The next best is 32, then come in descending order 40, 37, 36, 35, 34, and 33, which is the lowest Juego. Totals of 39 and 38 are not possible, and if your cards total 30 or less, you don't have a Juego.

Common Variants

Mus has several common variants, including Mus with four kings and four aces, Juego Real, variations in signals, Mus Visto, replacement cards for 4-5-6-7, Mus with Ten Kings, and Mus for three, five, or six players.

Beginner Mistakes to Avoid

Beginners should focus on understanding the ranking of the cards and the four ways of comparing hands (Grande, Chica, Pares, and Juego). Additionally, it's essential to understand the betting procedure and the opportunity to propose "Mus" during the game. As you become more comfortable with the game, you can explore the various variants and strategies to improve your gameplay.
