Truc, pronounced [tʁy(k)] in France and [tɾuk] in Spain, is a 15th-century bluff and counter-bluff trick-taking card game which has been likened to poker for two.

It is played in Occitania,[1] Sarthe (where it is known as trut), Poitou (tru) and the Basque Country (truka), and is still very popular in the Valencia region (joc del truc).

More elaborate versions are widely played in Argentina, Uruguay, Venezuela, Paraguay and Brazil under such names as Truco, Truque and Truquiflor.

The French version Le Truc has become more widely known in the English-speaking world and among hobbyist gamers after Sid Sackson included it in his popular book A Gamut of Games (1969),[2] it being a translation of E. Lanes' 1912 book, Nouveau Manuel Complet des Jeux de Cartes.

[4] Francesc de Borja i Moll, in his Diccionari Català (1993), offers a similar definition, recalling the hierarchy of the cards as: 3 2 A K Q J 9 8 7 6, and a brief entry on the Matarrata variant, a similar game in which the 7 ♦ ranks higher than 7 ♠, A ♣ and A ♠.

[5] Truc is closely related to the old English game of Put, which was first described by Cotton in The Compleat Gamester (1674).

[6] In France it is played with a French-suited Piquet pack, the cards ranking 7 8 A R D V 10 9 in each suit, whereby R is the Roi (King), D the Dame (Queen) and V the Valet (Jack).

[2] In Catalonia in Spain, Truc is played with a Spanish-suited pack of 40 cards ranking 3 2 1 R C S 7 6 5 4, whereby R is the Rei (King), C is the Cavall (Cavalier) and S the Sota (Jack).

If both cards played are of equal ranks, the trick is then considered "spoilt", belonging to none of the players (but during scoring is effectively awarded to the player who captured the first trick of that hand), and the same leader leads the next.

The opponent may either concede, in which case the increase does not take effect and the player that offered it scores the number of points the round was set at, or may themself announce "My remainder", in which case the player that wins the round wins the game.
