About this Game
Want to play Mus card game online? Mus is a Basque partnership card game where four players compete in two teams of two. It's one of Spain's most beloved card games and a cornerstone of Basque culture. With centuries of history, you'll find people playing Mus in bars and cafes all across Spain every single day.
On Stone Online, play Mus instantly — free, no signup, no download. Team up with a partner and face off against opponents from around the world, right in your browser.
What makes Mus truly unique is the signaling (señas) system between partners. You can tip off your teammate about your hand using pre-agreed signals like eye movements and lip gestures — and these signals are officially allowed by the rules, making Mus one of the most social card games ever created.
How to Play
You play with a 40-card Spanish deck. 3s count as Kings, and 2s count as Aces. Deal 4 cards to each player. First comes the card exchange phase (mus), then four betting rounds.
The rounds go in order: Grande (highest hand), Chica (lowest hand), Pares (pairs), and Juego (hand total of 31 or more). In each round, a team can declare 'Envido' (bet) or pass. The opposing team can accept, raise, or fold. Folding gives up that round's base points. After all rounds, tally the scores. First team to 40 points wins. You track points using stones (piedras).
