Mus: The Complete Guide to Spain’s Most Beloved Card Game

Introduction

Mus is Spain’s national card game, played passionately in bars, homes, and social clubs across the Basque Country and all of Spain. It is a partnership bluffing game — and the only Spanish card game where signaling between partners is not only allowed but essential. Walk into any tavern in Bilbao, San Sebastián, or Madrid, and you will hear the unmistakable sounds of Mus: stones clinking on tables, players calling “¡Órdago!”, and spirited debates about who had the better hand.

Unlike poker, where players hide everything from everyone, Mus thrives on a delicious paradox: you must communicate openly with your partner using standardised facial signals, while your opponents watch every twitch of your face. This creates a game of layered deception — are you signaling truthfully, or is that lip bite a bluff designed to trick the opposing pair into folding?

Mus has been played for centuries and remains deeply embedded in Spanish culture. Major tournaments draw thousands of players, and the World Mus Championship is a fiercely contested annual event. Whether you are a seasoned card player looking for a new challenge or a complete beginner curious about one of Europe’s greatest card games, this guide will teach you everything you need to start playing.

The Deck: The Baraja Española

Mus is played with the 40-card Baraja Española (Spanish deck), one of the oldest and most beautiful card decks in the world. If you are familiar with standard French-suited cards, the Spanish deck will feel exotic but quickly intuitive.

The Four Suits

• Copas (Cups) — ornate chalices, roughly equivalent to Hearts
• Espadas (Swords) — curved blades, roughly equivalent to Spades
• Bastos (Clubs) — thick wooden cudgels, roughly equivalent to Clubs
• Oros (Coins) — golden coins or medallions, roughly equivalent to Diamonds

The Ranks

Each suit contains 10 cards numbered 1 through 7, plus three face cards:

• 1 (As / Ace) — the lowest numerical card
• 2 through 7 — pip cards
• 10 — Sota (Jack/Page) — the first face card, depicted as a young page
• 11 — Caballo (Knight/Horse) — a mounted horseman
• 12 — Rey (King) — the King, highest card

Note: the 8s and 9s do not exist in the standard 40-card Baraja. The numbers jump from 7 directly to the Sota (10).

The Critical Mus Rule: 3s and 2s

Here is the rule that makes Mus unique among Spanish card games: all 3s count as Kings (value 10), and all 2s count as Aces (value 1). This means the deck effectively has only six distinct card values: 1 (Aces and 2s), 4, 5, 6, 7, and 10 (Sotas, Caballos, Kings, and 3s). This dramatically increases the likelihood of pairs, three-of-a-kind, and four-of-a-kind combinations, which is fundamental to how Mus plays.

Object of the Game

The object of Mus is to win betting rounds across four categories — Grande, Chica, Pares, and Juego (or Punto) — and accumulate enough points for your partnership to reach the target score before your opponents do. Points come from winning bets, and the game is as much about bluffing and reading your opponents as it is about holding good cards.

The first partnership to reach the agreed target (typically 5 amarrakos, equalling 25 points) wins the game.

Setup & Deal

Mus is always played by four players in two fixed partnerships. Partners sit across from each other at the table, so that play alternates between the two teams.

1. Choose a dealer. Any agreed method works — cutting for the highest card, youngest deals first, or simply volunteering. The deal passes to the right (counter-clockwise) after each hand.
2. Prepare scoring materials. Each partnership needs small stones or tokens called piedras (at least 22 total) and larger stones called amarrakos (at least 4 total). Coins, beans, or poker chips work perfectly.
3. Shuffle and deal. The dealer shuffles the 40-card deck and deals 4 cards to each player, one at a time, starting with the player to the dealer’s right (the mano — the “hand” player who acts first in every betting round).

The Mus Phase: The Unique Card Exchange

Before any betting begins, Mus features a card exchange phase that has no equivalent in any other major card game. This is the Mus phase, and it is one of the game’s most distinctive and strategically rich elements.

1. The mano speaks first. The player to the dealer’s right looks at their hand and says either “Mus” (requesting a card exchange) or “No Mus” (also called “No hay Mus” or simply “Corto”).
2. All must agree. Moving counter-clockwise, each player in turn says “Mus” or “No Mus.” If any single player says “No Mus,” the exchange is blocked for everyone and the betting rounds begin immediately.
3. If all say Mus: each player discards as many cards as they wish (zero to four) face down. The dealer then distributes replacement cards from the deck to each player to bring them back to four cards.
4. Repeat. After drawing new cards, the Mus phase starts again from the mano. Players can request Mus multiple times — there is no limit. This continues until someone finally says “No Mus.”

The Four Betting Rounds

Once someone says “No Mus,” the hand proceeds through four betting rounds, always in the same order. Each round evaluates the players’ hands according to a different criterion. The mano always acts first.

1. Grande (Highest Hand)

   In Grande, the partnership with the best high cards wins. Hands are compared card by card from the highest card downward. Kings (and 3s, which count as Kings) are the best. If the highest cards tie, the second-highest cards are compared, and so on. The ranking for Grande from high to low is: Rey/3 (King) > Caballo > Sota > 7 > 6 > 5 > 4 > As/2 (Ace).

   Grande is always played — every hand has a best high card combination.

2. Chica (Lowest Hand)

   Chica is the mirror image of Grande: the partnership with the best low cards wins. The ranking is completely inverted. Aces (and 2s, which count as Aces) are the best cards for Chica. A hand of four Aces/2s is the ultimate Chica hand.

   Like Grande, Chica is always played. The ideal strategy is to hold cards that are strong in multiple categories simultaneously.

3. Pares (Pairs)

   Pares is only played if at least one player holds a pair or better (remember, with 3s counting as Kings and 2s as Aces, pairs are quite common). The combinations from best to worst are:

   • Duples — two different pairs (e.g., two Kings and two Aces). Worth 3 bonus points to the holder even without betting.
   • Medias — three of a kind. Worth 2 bonus points.
   • Pares — a single pair. Worth 1 bonus point.

   If both teams have pairs, the better combination wins the bet. Within the same type, the higher-ranking cards break ties. If neither team has any pairs, this round is skipped entirely.

4. Juego / Punto (Game / Point)

   Each player adds up the values of their four cards. Face cards (Sota, Caballo, Rey) and 3s all count as 10. The 2s count as 1 (like Aces). All other cards count at face value.

   • If any player has a total of 31 or more, the round is called Juego. The best Juego hand is exactly 31, followed by 32, then 40 (four Kings/face cards), then 37, 36, 35, 34, 33. Juego is worth 3 bonus points (or 2 points if won by default when opponents fold).
   • If no player reaches 31, the round becomes Punto. The hand closest to 31 wins. Punto is only worth 1 bonus point.

Betting Mechanics

In each of the four rounds, the betting follows the same structure. The mano (or their partner, whoever holds the relevant cards) acts first:

• Paso (Check) — decline to bet, passing the action to the other team. If both teams pass, the round is resolved by simply comparing hands, and the winner gets 1 point.
• Envido (Bet) — place a bet of 2 or more points. The opposing team must respond.
• Quiero (Accept) — the opposing team accepts the bet. The round will be resolved by comparing hands, and the winner takes the wagered amount.
• No Quiero (Fold) — the opposing team declines the bet. The betting team immediately collects 1 point without showing cards.
• Órdago (All-in!) — the ultimate bet. An Órdago stakes the entire game on this single round. If accepted, the partnership with the better hand wins the game immediately. If declined, the betting team collects just 1 point. The word comes from Basque (“hor dago”) meaning “there it is.”

Teams can also raise each other’s bets. If Team A bets 2, Team B can raise to 4 (or any higher amount, or Órdago). Team A must then Quiero, No Quiero, or raise again. This back-and-forth can escalate dramatically.

Scoring: Piedras and Amarrakos

Mus uses a distinctive physical scoring system that adds a tactile, satisfying element to the game:

• Piedras (small stones) — each worth 1 point. Partnerships keep these in front of them on the table.
• Amarrakos (large stones) — each worth 5 piedras. When a partnership accumulates 5 small stones, they exchange them for 1 amarrako.

Points are scored from multiple sources in each hand:

• Betting wins — the wagered amount in each of the four rounds
• Default wins — 1 point when opponents fold (No Quiero)
• Bonus points — awarded for Pares (1–3 points depending on combination type) and Juego (2–3 points)

A standard game ends when one partnership reaches 5 amarrakos (25 points). In tournament play, the target may be higher. Points from betting rounds are awarded in a fixed order (Grande, Chica, Pares, Juego/Punto), which matters when both teams are close to winning — the team that earns the winning point in an earlier category wins, even if the other team would have scored more total points from later categories.

Partner Signals: The Famous Mus Signals

This is what makes Mus truly unlike any other card game in the world. Partners are allowed — and expected — to signal each other about the strength of their hands using standardised facial gestures. These signals are known to all four players, which means opponents can see your signals too. This creates an extraordinary game within the game: are you signaling honestly, or setting up a bluff?

The Standard Signals

• Biting the lower lip — signals a good hand for Grande (strong high cards)
• Puckering the lips (as if to kiss) — signals a good hand for Chica (strong low cards)
• Showing the tip of the tongue — signals having Pares (pairs or better)
• Raising the eyebrows — signals having Juego (hand total of 31 or more)

These signals are completely legal and expected in every form of Mus, from casual home games to world championship tournaments. However, players are free to signal falsely — biting your lip when you have terrible Grande cards is a perfectly legitimate bluff. The art lies in knowing when your partner is signaling truthfully and when they are performing for the opponents’ benefit.

Experienced Mus players develop remarkable ability to coordinate with their partners through subtle combinations and timing of signals. Some partnerships develop additional nuances — the intensity of the lip bite, a quick versus slow eyebrow raise — to communicate finer details within the accepted signal framework.

Strategy Tips

History & Basque Origins

Mus is widely believed to have originated in the Basque Country (Euskal Herria), the culturally distinct region straddling the border between northern Spain and southwestern France. The word “Mus” itself is Basque, and many of the game’s core terms — Órdago (“hor dago” — “there it is”), amarrako (from “hamar” — “ten”), and the word Mus (possibly from “mutur” — “lips/face,” referencing the signals) — are unmistakably Basque in origin.

The earliest written references to Mus date to the 18th century, though the game is almost certainly much older. Basque culture has a strong oral tradition, and card games were passed down through generations in the cider houses (sagardotegiak) and village squares long before anyone thought to write down the rules.

From its Basque heartland, Mus gradually spread across the entire Iberian Peninsula. By the 19th century it had become popular throughout Spain, and by the 20th century it was firmly established as the country’s most socially important card game. Unlike many card games that are associated primarily with gambling, Mus has always been fundamentally a social game — played for pride, camaraderie, and the simple pleasure of outwitting your opponents.

The game also crossed the Atlantic with Spanish emigrants and is played in parts of Latin America, particularly in Argentina, Mexico, and Colombia, as well as among Basque diaspora communities in the United States, especially in Nevada and Idaho.

Tournament Mus

Competitive Mus is thriving. The World Mus Championship (Campeonato Mundial de Mus) draws partnerships from across Spain and beyond, and regional tournaments are held in virtually every Spanish province. The Basque Country, Navarra, and Madrid are particular hotbeds of competitive play.

Tournament rules are highly standardised. The target score is typically 5 amarrakos (25 points) per game, and matches are often played as best-of-three games. Strict rules govern the timing and visibility of signals — they must be made openly, not hidden. Tournament organisers provide official scoring stones, and an umpire may be present for high-stakes matches.

What makes tournament Mus special is the emphasis on partnership chemistry. The best pairs have played together for years or even decades, developing an almost telepathic understanding of each other’s tendencies, signal nuances, and risk tolerance. It is common for tournament partnerships to stay together for an entire playing career, much like a doubles team in tennis.

Online platforms have also brought Mus to a global audience. Several Spanish-language apps allow players to compete remotely, though purists maintain that without the facial signals and the clinking of stones, something essential is lost. The physical, social, and theatrical aspects of Mus — the lip-biting, the dramatic Órdago calls, the raucous post-hand debates — are what elevate it from a card game to a cultural institution.
