Truco Offline is a card game that can be played without an internet connection. The game involves four players, divided into two teams, or six players, divided into two teams of three. In the Truco Cego version, the 8s and 9s are removed, and the game is played with the numbers 1 to 7, plus the Jack, Horse and King.

The game is played until one team reaches 24 points, divided into two halves, the lower half called "ruins" and the upper half called "goods." The first team to reach 12 points resets the score and gets a "ruin." If the team reaches 12 points again, they get the "goods" and win the game. The popular appeal of the game comes from its exciting betting system, where each score can be bet on to earn more points for the team. Bluffing and deception are also fundamental to the game.
